    Some slow cookers come with digital settings, which allow you to set a timer and even choose a keep-warm mode for when your meal is done cooking, so you can dive straight into a hot freshly cooked meal. Manual slow cookers are typically cheaper, but need to be switched off in person when your meal is done cooking.

    You can choose from low, medium and high heat settings with the best slow cookers, for tender slow cooked beef and lamb, as well as flavour-packed stews and curries. Some even come with an stove-safe insert for searing meat before cooking for added flavour, or sautéing onions and garlic. Check out our roundup of the best rice cookers for more cooking essentials.

    Best slow cookers 2021

    1. 4.5L DuraCeramic Sauté Slow Cooker by Crock-Pot

    Best slow cooker overall

    Digital? No
    Capacity: 4.5 litre
    Features: Hinged lid, multi-use bowl, non-stick

    Some things may deter you from cooking. Having to transfer food from a pan to a pot, cleaning up or that annoying puddle of water you get from putting the lid down on the worktop. If that’s you, you need this smart model.

    This slow cooker has been designed to be easy to clean – food residue just slides off. It’s oven and hob safe, so you can sauté in it. Be aware that the handles get hot, too. Slot in the hinged lid, which also has a seal around the edge, and you’re good to go.

    Its manual control features three heat settings – high, low and keep warm – and there’s an indicator light. Given its mid-range price, there are a few extra features you’d expect to have like a timer or automatic controls. The bowl isn’t dishwasher safe. Also, despite being induction-compatible, this type of hob wouldn’t recognise it during testing. Beware, those with older induction hobs may struggle.

    It’s also awkward to fit the bowl in the base after the lid, so it has to be put in first and taken out after the lid is removed. Having said all this, it made a fantastic Bolognese sauce in four hours on high. Rich and tasty, with perfectly cooked meat and veg.

    2. Russell Hobbs Sous Vide Slow Cooker

    Best large slow cooker for families

    best slow cooker

    Digital? Yes
    Capacity: 6.5 litre
    Features: Sous-vide, timer settings, keep warm mode, temperature probe

    The Russell Hobbs 25630 Slow Cooker is a true multi-tasker. Armed with a temperature probe and sous vide capabilities, you can make sure that your meat is cooked just right before you cut it open, or fill up a water bath for succulent sous vide fish or veggies. This digital slow cooker comes with a probe and sous vide setting on its front control panel, as well as a regular slow cooker mode. You can set a timer, and choose between high and low heat, as well as a keep warm mode. 

    We tested the Russell Hobbs 25630 out on slow cooker stews, as well as a whole cooked chicken. This is when the temperature probe came in particularly useful, because we were confident that our chicken was cooked perfectly when we took it out, with none of the guesswork that come with roast chicken timings. Other features we enjoyed included the lock-safe lid and dishwasher-safe pot, both of which made mealtime easy and stress-free. 

    If you buy this slow cooker, you’ll probably want to use its sous vide mode. One thing we found is that you should account for how long the water will take to come to temperature when planning your meal around this. For us, it took about 20 minutes, so we suggest adding already hot water to speed this process along.

    3. Bosch AutoCook Multicooker

    Best slow cooker for keen entertainers

    best-slow-cookers-3 Bosch AutoCook

    Digital? Yes
    Capacity: 5 litre
    Features: Multi cooking, smart controls, dishwasher-safe accessories

    There’s one area in which slow cookers truly excel and that’s producing top-notch meals that taste like you’ve been slaving away in the kitchen all day. In fact, all you had to do is pop some ingredients in a bowl and walk away. This is what the AutoCook slow cooker does brilliantly, stewing and simmering away while you enjoy a glass of wine with your guests.

    Strictly a multi-cooker rather than a simple slow cooker, Bosch’s AutoCook Pro nonetheless performs the role with gusto. Offering up a five-litre cauldron-shaped round bowl, it provides good capacity without the awkward depth. It also uses induction to heat it evenly, removing the issue of hot spots. Also unlike a traditional slow cooker, there’s an abundance of controls to get to grips with. Some are more confusing than others.

    The silver lining of this button bonanza is that you have more flexibility with your slow cooking time and temperature as it goes as low as 40C. In tests, the AutoCook slow-cooked eggs in their shells to gently poach them. The resulting eggs were still slightly watery after an hour. However, this slow cooker could be a time-saver for a dinner party. It made yogurt on a slow cooking programme that took eight hours and resulted in creamy semi-set yogurt. Parts of the lid need to be washed by hand but the bowl and its accessories are all dishwasher-safe.

    4. Lakeland 1.5L Slow Cooker

    Best compact slow cooker

    Digital? No
    Capacity: 1.5 litre
    Features: Compact, energy-efficient, dishwasher-safe

    Slow cookers rarely come as dinky as this compact model. If you’re only preparing meals for one or two people, its size will be a bonus, both for storage and energy efficiency. Comprising a 1.5-litre ceramic bowl this slow cooker has three manual settings of high, low and auto. The pot heats to a high temperature before dropping to a lower one (120C to 60C). A base element wraps around the bowl for even heat distribution.

    It might be small but it’s perfectly formed. It also comes with lots of advice for getting to grips with slow cooking but strangely, only a couple of recipes. The size of this slow cooker will be limiting for anyone wanting to make more than a small meal. In tests, it was used to make chilli. All the ingredients had to be sautéed in advance before placing in the bowl. Once in, though, they simmered away nicely, the glass lid coming in handy for checking on progress.

    The exterior also doesn’t get too hot when it’s in use. Both the lid and bowl are dishwasher-safe, making clean-up effortless. Also, as neither are especially big, they’re not overly heavy. The resulting chilli, after six hours on auto, was great, with moist meat, no dry beans and slightly hotter than serving temperature.

    5. Russell Hobbs Chalkboard Slow Cooker

    Best budget slow cooker

    Best-slow-cooker-russell-hobbs

    Digital? No
    Capacity: 3.5 litre
    Features: Chalkboard exterior, dishwasher safe

    There’s lots to like about the Chalk Board Slow Cooker. It has a 3.5-litre ceramic bowl that can cook up to three or four portions. Its matt black finish is designed to be written on in chalk. So, for example, you could write on what time dinner will be ready, what’s cooking inside or what time to add a final ingredient. It features standard settings of high, low and warm but the control dial is manual so you’ll need to be there to switch between them.

    It’s affordable and a good medium size with enough capacity for newbies to experiment with, without occupying too much room. During testing, a few quirks emerged that you’ll need to work around. One is that adhesive left behind from a sticker made writing on the chalkboard area difficult. Another is that there’s no light to indicate it’s on, so you’ll need to preheat it before decanting dinner.

    When used to cook soup on high, some steam and condensation escaped from the lid, leaving a puddle of water on the worktop, while the exterior grew very hot. However, the low setting produced a tasty Bolognese meat sauce and the warm function kept food at a hot enough serving temperature. The pot and lid are dishwasher-safe, too, which is advisable as it’s tricky to see food on the pot’s black glaze.

    6. Sage The Fast Slow Pro

    Best slow cooker for batch cooking

    Digital? Yes
    Capacity: 6 litre
    Features: Multi cooker, smart display, sear function and more

    Removing the need to sauté in a pan before transferring to the pot, the Fast Slow Pro is as useful for slow cooking converts as it is to experienced cooks. Functioning as both a slow cooker and a pressure cooker, it includes sensors at the top and bottom to monitor temperature. This makes inconsistently cooked stews a thing of the past. Also, you can set this slow cooker to heat for two to 12 hours – ideal if you’re going to be out of the house for a long day.

    Its slow cook presets correspond to different types of food, such as pudding, casserole, stock, pot roast and legumes – it also has a custom setting. All settings switch automatically to keep your dish warm at the end. In testing, the sear function was a little too hot and caused oil to spit. Also, the bowl was an awkward shape for turning a chicken while browning.

    The chicken was cooked on the pot roast programme after, set on a rack over water, and emerged juicy and so tender the meat fell off the bone. The machine also slow-cooked stock on low for six hours. This produced a rich, flavourful broth without making the kitchen smell from hours on the hob. The slow cooker’s ‘reduce’ function was useful for bubbling away excess liquid after slow cooking.

     7. Morphy Richards Sear and Stew Slow Cooker

    Best slow cooker for ease of use

    best-slow-cookers-7-Morphy-Richards-460005-Sear-and-Stew-3.5L-Digital-Slow-Cooker-460005-hero.jpeg-1.jpg

    Digital? Yes
    Capacity: 3.5 litre
    Features: Smart display, can be used on the hob, automatic keep-warm

    Feature-packed, versatile and so simple to get the hang of, you’ll be slow cooking everything you can with the Sear and Stew. It could revolutionise your mealtimes. Its pot is made from aluminium rather than ceramic, meaning you can use it on the hob (not induction) to brown meat and veg. You can then transfer it to the base to slow cook on either high or low heat. Then all you need to do is set a cooking time in increments of 30 minutes using its digital display. When the time’s elapsed, it’ll switch automatically to a two-hour keep warm option.

    The Morphy Richards slow cooker’s high setting can also be used to reduce liquid after cooking. In tests, it was used to make Bolognese, first sautéing meat and veg on the hob. The pan’s base was slippery on the cast-iron support of a gas burner, so it had to be held in position when stirring. This required gloves as the handles grew hot. After, it was transferred to the base to cook on high for four hours.

    The slow cooker was easy to set, though the timer button seems a bit redundant alongside up and down buttons for toggling the duration. While cooking, it bubbled away well. The exterior of the base only grew slightly warm. After the time had elapsed, it switched to keep warm, which was still hot enough to serve. Both the pot and the toughened glass lid are dishwasher-safe so clean-up was straightforward.

    8. Swan 1.5L Slow Cooker Retro

    Best slow cooker for a classic kitchen

    Best-slow-cooker-swan-retro

    Digital? No
    Capacity: 1.5 litre
    Features: Retro look, dishwasher safe, transparent lid

    Proving that limited worktop on space doesn’t mean compromising on style, this cheerful slow cooker is a welcome departure from so much stainless steel and purely functional designs. Not only is it available in a wide range of colours from pastel Blue to bright Red, it comes with generous chrome handles and a matching control knob.

    Inside, a white ceramic pot makes a change from the usual black, and it’s topped off by a glass lid. It’s quite compact, so best suited for solo households or couples and comes with plenty of recipes to try. The only catch here is that you’ll have to adjust the quantities to suit the size of its bowl as they’re portioned for bigger pots.

    One plus is the cooker’s auto mode, which cooks on the high setting before switching to low heat for the remainder of the time required. It wasn’t clear at what point in the cooking duration this happens but it provides a useful alternative to its high and low settings. Sadly, there’s no keep warm option, only the low setting if dinner needs to be delayed.

    We used it to cook chilli cooked on high, which required sautéing some ingredients beforehand in a pan. After two hours of cooking, the chilli was bubbling and the lid clear, making it easy to check on progress without lifting it.

    After four hours, there had been about an inch of liquid evaporation, with some of the meat slightly dry but soft beans. We also used it to simmer rice pudding on the low setting. After five hours there was a slight browned crust around edge but no burns and plenty of liquid, so the pudding wasn’t too thick or clumpy.

    The bowl and lid were both easy to clean and dishwasher safe.

    9. Tower 3.5 litre Slow Cooker

    Best value slow cooker

    best slow cooker

    Digital? No
    Capacity: 3.5 litre
    Features: Range of colours, ceramic pot, glass lid

    If you’re on the hunt for an affordable slow cooker with plenty of capacity, this model should fit the bill. Its black ceramic pot has enough room for making a batch of soup or a family-sized casserole plus there’s stacks of advice in the instruction for converting standard recipes and getting the most from slow cooking.

    Where it falls short is recipes to try – there’s just two – and you’ll still need to sauté some ingredients in a separate pan. Its settings are low, high and keep warm, controlled by a neat knob at the front.

    It’s not all about functionality though – the cooker’s available in a choice of red, black or stainless steel finishes. The lid and pot are dishwasher-safe, although the pot isn’t too heavy and can be washed by hand easily enough.

    We made chilli con carne in it on the high setting. Quite a lot of condensation formed in minutes from putting the lid on, so it seemed to trap the heat and liquid well initially. After a few hours, we could see that the mixture was simmering around the edges.

    Around three hours into cooking, there was visible steam emerging from the edges of the lid even though its position hadn’t altered. At the end of cooking, there was still enough liquid left, although some smaller bits of beef were a little chewy.

    Next, we cooked rice pudding on the low setting. Four hours into cooking, we noticed that the milk had started to burn into a crust so had to turn it off and remove the remaining pudding. Some liquid was still left at the bottom of the pot, suggesting that the heat distribution wasn’t as even as it could be. Some dishes may require some extra stirring to help resolve this.

    10. Cookworks 6.5L Slow Cooker

    Best budget slow cooker for big portions

    best-slow-cookers-1 Argos Cookworks 6.5L Slow Cooker - Black

    Digital? No
    Capacity: 6.5 litre
    Features: Large capacity, three heat settings, glass lid

    Affordable slow cookers can sometimes be restrictive in size, but not this capacious model. It comes with a 6.5-litre oven-safe ceramic bowl. That’s big enough to fill with enough stew, curry or soup to easily satisfy a family of five or six.

    On top, there’s a toughened glass lid, while on the base it has three settings – low, high and ‘warm’. However, there’s no sauté function and the pot isn’t hob-compatible, so pre-cooking will need to be done in a pan.

    It’s also advisable to preheat it before the contents are added to the bowl. In testing, this slow cooker made a delicious chilli con carne on high, although a few pieces of mince were a little dry. It also slow-cooked a tender beef brisket. Although, once simmered on low and switched to the ‘warm’ function, the meat cooled faster than the sauce.

    It was only lukewarm when served, suggesting that the ‘warm’ switch may be better for recipes with more consistency, rather than joints of meat. The bowl and lid aren’t dishwasher-safe but washing by hand was straightforward, if a bit awkward. As this slow cooker is black, so it’s hard to see baked-on food debris. Plus, the bowl is very heavy.

    How to buy the best slow cooker for you

    Best-slow-cookers

    Why do I need a slow cooker?

    Slow cookers have got so much going for them, it’s hard not to love them. Not only will a good one save you time and effort in the kitchen, it’ll save you money too. Slow cookers transform cheaper cuts of meat into tender dishes and liven up economical healthy pulses, like lentils, beans and peas. Plus, while they can be on all day, it’s at such a low wattage that it will only cost pennies.

    Slow cookers are also brilliant for less-than-confident cooks, easily creating all those meals that seem a bit scary on the hob. That’s because slow cooking develops the flavours of food for richer, tastier results. It’s not just dinners that slow cookers excel at making either. They make great porridge, granola, stewed apples, bread and butter pudding, fudge and dips. You can use your slow cooker to melt chocolate, as a Bain-marie.

    How much should I spend on a slow cooker?

    Slow cookers are one of the most affordable small appliances, and you can buy one for as little as £20. At this price, it’ll be pretty basic in terms of features. Also, the dish may be the traditional choice of heavy, potentially breakable, ceramic. However, you should still be able to simmer and stew whatever you like.

    Spend more and you’ll find a greater array of features, such as automatic functions. A bigger budget will allow for a durable metal pot that can be used on your hob and is dishwasher-safe. Stretch your budget to the £100 mark and your slow cooker may also double up as a multi-cooker, so it can cook fluffy rice and steam food, too.

    What are the main features of a slow cooker?

    Best-slow-cookers-russell-hobbs-2

    Slow cooker capacity

    The first thing you need to consider with any slow cooker is its capacity – each will list its bowl size in litres. Bear in mind that this won’t translate to the same amount of food, as you shouldn’t fill slow cookers to the brim. This gap allows your food to bubble and simmer properly. The usable cooking space will be around three-quarters of its bowl size, for example, a five-litre cooker can accommodate around four litres of food.

    Slow cookers range in size from a compact 1.5 litres to a 6.5-litre bowl, so be sure to choose the right size for the way you intend to cook. As a rough guide, 1.5-3 litres will feed one or two people, 3-5 litres, three or four people and anything over five litres should suit a large family, with six litres or more ideal for batch cooks who like to fill the freezer. Alternatively, a larger cooker is great for those who like to eat what’s leftover for lunch the next day.

    Slow cooker controls

    Most slow cookers will have similar standard controls – high heat for meals cooked in less than a few hours, low heat for all-day cooking. A ‘keep warm’ mode should hold food at a serve-able temperature without actually cooking it. Some cookers will switch to ‘keep warm’ automatically after an elapsed cooking time, while more basic models need this altered manually.

    Slow cookers with digital controls may also have a delay start, which is ideal if you’re out of the house for more than eight hours. This means you can start cooking at a time to suit you – while it’s hard to overcook recipes with a lot of liquid, this gives more freedom with dishes that could potentially start to dry out. A timer is another handy feature – this will either turn the machine off after cooking or put it into a limited time keep warm mode.

    One-pot solutions

    Basic slow cookers won’t get hot enough to sauté meat or vegetables, so you’ll need to do this in a pan before transferring the contents to the bowl. However, more expensive models offer a different one-pot solution. This can either be bowls that you use on your hob or in your oven in place of a pan (some will even be induction compatible). They will need to be moved to the slow cooker base. Machines with a sauté function for high-heat browning can simply be switched to slow cooking.

    The advantage of this is not leaving all that lovely seared flavour behind in a pan, and it reduces washing-up. Finally, look for a slow cooker with a transparent lid, so you can keep an eye on your food’s progress. Lifting the lid of a slow cooker while it’s in use lets out heat and steam, prolonging cooking time. It’s always best to be able to see what’s going on without doing so.

    Are slow cookers easy to clean?

    Best-slow-cooker-lakeland

    Image credit: Lakeland

    You’ll only have a lid and a pot to wash but even so, it’s best to check the cleaning instructions. Budget models with large ceramic dishes may not be dishwasher-safe and the pot can be heavy and cumbersome to clean thoroughly by hand. Dark glazes may also make it hard to see stuck-on food. A non-stick coating on a lighter pot can be a better choice for straightforward maintenance.

    What other key questions do I need to ask?

    • Does your slow cooker have good heat distribution? Some can suffer from hot spots that cause drying out in corners or at the base. Uneven heat is something that’s more likely to occur in larger bowls.
    • Do you need a round or oval bowl? If you plan on making stews and curries, round bowls are ideal as the shape provides even heat. However, they can be awkward to use for a whole chicken or lamb shanks – in which case, an oval bowl will make getting meat in and out easier.
    • Do you plan to put food in and dash out of the house? Slow cookers can take a while to warm up, so look for a model with a light to show it’s on. This is a little extra reassurance that you’ve remembered to switch on the socket and aren’t coming home to uncooked dinner.
    • Do you need a separate source of recipes? Most cookers will come with a few ideas, which is useful for getting to know what sort of dishes you can make. However, there’s a huge amount of recipes online, so don’t just stick to what it comes with.
