How to buy the best pressure cooker

We explain how to choose between electric and stove-top models, how to choose the right size of pressure cooker for you, and features to look out for.

When you think of pressure cookers you may remember traditional models that screeched and rattled on the hob. Cast these thoughts aside, though, as the new generation of pressure cookers have been updated to suit a modern kitchen.

Today’s pressure cookers come in different shapes and sizes, but there are two main types – stove-top pressure cookers and electric pressure cookers. They work in fundamentally the same way, using a build-up of steam pressure to raise the temperature above boiling point and force liquid into food. This means that food cooks more quickly. It also helps to develop flavour and make food more tender.

Not sure whether you should buy an electric or stove-top model? If you only want a quick way to cook soup, are a confident cook or short on kitchen space, a stove-top pressure cooker might be best. However, if you want to be able to 'set and forget' your meal, and let an appliance do the hard work for you, an electric pressure cooker might be a better option. 

You could also consider a microwave version. There are fewer of these around but they can be good as long as you don't need a large capacity.

Electric pressure cookers

Electric pressure cookers are standalone appliances, similar to multi-cookers or slow cookers. Pricewise, they start around the £50 mark and go up to around £200.

Their main benefit is that they pretty much automate the cooking process. You simply select the pressure level or cooking function you want, and the appliance does all the work, with an integrated timer letting you know when to release the pressure and when your meal is ready. This makes them a good option for people who are new to pressure cooking or those who don’t want to watch over their appliance.


  • Set-and-forget functionality, no need to worry about pressure levels
  • Some can also be used for other functions such as slow cooking


  • Tend to be more expensive than stove-top models
  • Take up a fair bit of space in your kitchen
  • Typically lower pressure levels make them slower to cook than stove-top models
  • Temperatures aren't as high, so sautéing not as effective as the hob

Electric pressure cookers: features to consider

If you’ve decided that a electric pressure cooker is right for you, here are some things to think about when choosing between models:


Electric pressure cookers generally have smaller capacities than stove-top pressure cookers. The smallest models have about a three-litre capacity, but most are around four to six litres, which should be plenty to make a meal for a family of four. The Instant Pot comes in a larger eight-litre option, too. 

A larger capacity will add to the price, so go for the smallest option that works for your household if you're looking to save money.


If you want maximum flexibility, look for a pressure cooker, such as the Instant Pot, that is also a multi-cooker. These appliances can double up as a steamer, slow cooker, rice cooker, or even have dedicated settings for porridge and yoghurt.

Multiple pressure settings

Some electric pressure cookers only have one pressure setting, whereas others have two (for high and low pressure) or even more (the Sage Fast Slow Pro has eight). The low-pressure option makes cooking more energy efficient, as the cooker can switch to this setting once the food has cooked. It’s also useful for cooking more delicate foods such as leafy vegetables, pasta, eggs and fish.

Automatic pressure release

Some models (such as the Sage Fast Slow Pro) have an automatic pressure release. This makes the cooking fully automated, so you can choose your setting, leave your pressure cooker and come back to your finished meal, rather than having to release the pressure manually then waiting for it to complete. This will cost you more, though.

Sauté function

This will let you brown meat inside the pressure cooker with the lid off, saving you the time of transferring food between pan and pressure cooker, and the hassle of extra washing up. 

Delayed-start / keep-warm setting

If you love having a hot meal waiting for you, these features will give you more flexibility in when you put your ingredients in and take your food out.

Stove-top pressure cookers

Stove-top pressure cookers can initially be a little more daunting to use, as you need to monitor the level of heat on the stove to help the appliance reach and maintain pressure. But if you’re prepared to take a more hands-on approach to cooking, they have their benefits. They’re often cheaper than electric models (you can buy one for as little as £20) and, as they can reach higher pressure levels, they cook food even more quickly.

Most are made from stainless steel or aluminium, and can double up as a sturdy saucepan. They don’t have multiple functions for different foods like electric models do, but some come with accessories such as steaming baskets. 


  • Often cheaper with larger-capacity options available (up to 12 litres)
  • Can reach higher pressures
  • Easy to brown meat in the pan first
  • Can quickly reduce pressure on some models with cold water


  • Need to manually monitor the pressure levels and reduce heat
  • Fewer extra functions such as slow-cooking or yoghurt-making settings

Stove-top pressure cookers: features to consider

Here are the main things to think about when choosing a stove-top pressure cooker:

Size and materials

Like electric pressure cookers, stove-top models come in different shapes and sizes, starting at around 1.5 litres for a mini pressure cooker and going up to as much as 12 litres. You’ll want to consider how many portions you like to cook as well as how much storage space you have.

If you’re prepared to spend more, one of the main things your money will buy is better-quality materials. Pricier stove-top pressure cookers are often made of stainless steel instead of aluminium and have a thicker base, making them more durable than cheaper models. Some even have a lifetime guarantee.

Ease of use

Some hob pressure cookers have handles on either side, making them easier to carry, as they can be heavy when filled with food. Others have folding or removable handles, making storage easier.

All models will indicate when pressure has reached the desired level, but some have multiple pressure levels to choose from, or built-in timers and thermometers to take some of the guesswork out of the process. 

A two-valve mechanism gives you more choice for releasing pressure, either naturally by leaving it to cool, or speeding things up by sitting the pan in cold water or running some over the top.


For peace of mind, look for additional safety features such as a locking lid, a second pressure release valve (in case the first gets blocked) and an auto shut-off function.

For more information on pressure cooker safety features, see our guide to using a pressure cooker.

Pressure cooker spare parts

Whether you buy an electric or stove-top pressure cooker, you'll need to take care of the rubber sealing ring (gasket) that sits inside the lid. This helps to form an airtight seal so pressure can build up. If it's damaged, your pressure cooker won't work properly.

The gaskets need replacing periodically to keep your pressure cooker working at its best. They aren't usually too expensive but it's worth checking how readily available and expensive they are before you buy a pressure cooker, so you don't get stuck with a model that has hard-to-find or costly spare parts.

Ways to look after the gasket include:

  • Handwash in soapy water
  • Don't stretch or bend
  • Dry before putting back in the pressure cooker lid

Microwave pressure cookers

If you're short on space, you could also consider a microwave pressure cooker. These are usually made of silicone, so are easy to clean after cooking, whether you pop it in your dishwasher or wash it by hand. 

The microwave helps the silicone pressure cooker reach pressure almost instantly, so it’s one of the quickest ways to cook. However, you do have to compromise on size – models from Lakeland and Prestige only have a 2.2-litre capacity, which would struggle to feed a family of four.

Other gadgets to take the work out of meal prep

Not sure if a pressure cooker is for you? Here are some alternatives:

  • Slow cookers - if you’re interested in the hands-off approach to cooking, but would prefer to not have to release pressure, these will turn out tasty stews and curries for those prepared to wait.
  • Microwaves - these have the health benefits of pressure cookers, as well as the speedy cooking times.
  • Soup makers - if you just want to make soup, these automatic gadgets do the cooking and blending for you.
