The best slow cookers 2020

1. Tefal RK302E15 Multicook 8-in-1 multi-cooker – best value multi-cooker

Pros:

• pop-up vented lid
• fingerprint-free stainless steel exterior

Cons:

• only displays minutes left to cook in the last hour

The multiple functions, safety features and reasonable price of the Tefal 8-in-1 multi-cooker make this a highly desirable piece of kit. The recipes we tested were impressive. The beef stew was beautifully thick, thanks to the vent in the lid releasing vapour, and the gravy was glossy and dark. At the end of cooking, the meat stayed in large, meltingly tender chunks.

3. Sage the Fast Slow Pro™ – best slow cooker and pressure cooker in one

Pros:  

• stylish appearance
• impressive functions

Cons:

• price

The Fast Slow may be expensive and have fewer functions than some multi-cookers, but it's worth the investment for its great looks, searing, sautéing and reducing functions. It has a relatively small footprint for a multi-cooker and the build is solid – all features feel robust and well-built, from the strong handles to the hinged lid.

• can't sear ingredients

Available to buy from: 
Amazon (£29.99)
Tower (£38.49)

This slow cooker has simple, straightforward functionality and looks good enough to leave it sitting on the worktop. It may not come with the fancy flourishes and added settings of more expensive models, but its strength lies in its cooking performance and value for money.

Pros:  

• able to sear ingredients in the pot, including on induction
• option to delay start time

Cons:

Available from Lakeland (£59.99)

This is a seriously good choice if you want a larger machine for family meals or batch cooking. Being able to sear ingredients in the pot on the hob, including on induction, and the delayed start option are two functions worth having, with the added bonus that it cooks food superbly.

7. George 3-litre stainless steel slow cooker – best basic slow cooker

Pros:

• easy to use

Cons:

• flimsy construction

8. Morphy Richards Sear, Stew and Stir slow cooker – best everyday slow cooker

Pros:  

• handy stirring function
• ability to sear in the pot

Cons:  

• bulky

Available from: 
Morphy Richards (£54.99)
Amazon (£44.96)

This is a well-made, reliable appliance. It's bulky, but offers an automated stirring function and the ability to sear in the pot. It's worth noting that the stirring function isn't suitable for every recipe, for instance those using large joints of meat.

9. Salter EK2842 chalkboard 3.5-litre slow cooker – best slow cooker for innovative and practical design

Pros:  

• surprisingly useful chalkboard finish  
• small kitchen footprint 

Cons:  

• short electric lead

Available from: 
Robert Dyas (£24.99)
Amazon (£30.67)
Salter (£39.99)

With its great cooking results and reasonable price, this is an excellent option, especially for those with limited kitchen space. The quirky, chalkboard finish is a surprisingly useful feature for noting cooking times, as the machine doesn't have a timer. The stay-cool handles live up to their name, allowing you to easily lift out the inner pan.

10. Wilko 6-litre slow cooker – best budget slow cooker

Pros:

• bargain price
• family-sized 

Cons:  

• high setting is fiercely hot

Available from Wilko (£25)

This generously-sized cooker easily makes enough food for six people. The high setting is a little too fierce for some recipes but a few adjustments and you have excellent bargain buy. We recommend using the low setting for the best results. We were particularly pleased with the results of the chicken curry test – the sauce was glossy and the flavour excellent.

How we tested slow cookers

We tested a range of slow cookers, including multi-cookers, with two favourite BBC Good Food slow cooker recipes. The first, a slow cooker beef stew, was cooked on the high setting for 4 hours. As the meat requires searing before cooking, where this was an available setting on the cooker, we did this too.

The second, an easy slow cooker chicken curry, requires marinating overnight, making it perfect for switching on in the morning and leaving for 6 hours of cooking. The chicken isn't seared first, making it a fuss-free recipe to prepare. 

We scored the slow cookers against the following criteria:

Capacity and size: the bowl capacity and the footprint for using and storing in the kitchen

Heat retention: how the cooker holds heat for safety on the worktop and whether the food catches or burns

Ease of use: how easy it is to assemble and use

Functions:  additional functions on the cooker including browning, reheating, reducing and whether it is hob or oven-safe

Versatility: does the cooker make a range of dishes?

Quality of material: the material and the construction of the machines

Design features: the type of lid, handles, automatic warming, countdown and indicator lights

Finished results: the tenderness of the meat and vegetables, the consistency of the cooked sauce and the heat of the food when serving

Manual: how helpful was the instruction book and did it include recipes?

Packaging: excessive use of plastic in packaging was scored negatively

Which slow cooker should I buy? 

With so many variations of slow cookers out there, choosing can be confusing. Here are a few questions you might want to consider.

How many are you cooking for?
With sizes starting at 1-litre through to a whopping 6.5-litres, choosing the right size for you is imperative. The smallest sizes are suitable when cooking for one or two or those with small appetites. 3-litres to 4.5-litres (one of the most popular sizes on the market) serve four, and the large 6 – 6.5-litre models are super for families and batch cooking. It's also worth bearing in mind that the capacity stated on the sales blurb is the size of the bowl, not the working capacity, which can sometimes be half that. 

How much space do you have?
A slow cooker takes up space on the worktop and in the cupboard. There are two shapes, the round and tall, which has less of a footprint, and the oval, which takes up more room but can be more versatile. 

What is your price range?
If it is a straightforward, no-frills slow cooker you're after, then you can pick these up from £10. Choose digital models with additional features or multi-cookers with multiple cooking functions and the price jumps. These can also be cost-effective if you use all the extras.

Slow cooker vs pressure cooker

Both slow cookers and pressure cookers offer a convenient and versatile way to cook, as the machine takes on some of the work. They can both be effective at braising and stewing, however there are some key differences between the two gadgets. 

Slow cookers are plug-in electronic appliances that use a gentle heat over a long period of time (usually four hours or more) to cook liquid-based dishes.

Pressure cookers can be hob-top or electronic and operate at high temperatures, employing pressure to quickly work through ingredients that traditionally require slow cooking, such as hard pulses and tough meat cuts. Similar to slow cooking, pressure cooking is a wet cooking technique and liquid should always be used. 

As for one versus the other, there are pros and cons to both. Slow cookers can result in watery sauces, while pressure cookers can be intimidating to use. With practice and the right recipes, they can be very useful for busy households. Investing in a multi-cooker is a good way to get the best of both worlds.

Slow cooker tips

No liquid escapes from a slow cooker, so when adapting a recipe not specifically written for a slow cooker, reduce any added liquid by a third to compensate.

Don't remove the lid too often to avoid heat loss.

The inner pot needs to be at room temperature before you start cooking. If you've kept a slow cooker dish in the fridge, you must wait for it to warm up before turning it on.

Slow cookers vary considerably, so follow your manufacturer's manual for guidelines on temperatures and cooking times.

Rice and pasta dishes work best cooked on high for the shortest time possible. Always use easy-cook rice, rinsed well first – the more starch you rinse from the rice, the better the finished result. 

Take time to brown your meat really well. Slow cookers tend to leach meat of its colour, so it’s important for appearance and flavour that they are well browned to start with. Flavours won't become more concentrated because the liquid doesn't reduce, so try to pack in as much flavour as you can.

How to use a slow cooker: video

Gravy granules will add colour to stews, as food cooked in a slow cooker is usually pale. Marmite will do the same job. Season at the same time.

Use arrowroot or cornflour to thicken sauces by removing a spoonful of sauce from the pot and whisking in 1-2 tbsp of flour before adding it back in. 

A dash of cream or crème fraîche at the last minute will enrich sauces and soups.
