Which slow cooker to buy

Are slow cookers economical? You can pick up a slow cooker for as little as £15 (or as much as several hundred pounds) but price doesn't always equate to quality.

1. Cut down your prep time

One of the main attractions for many people is the ease of a slow cooker, so when you're looking for recipes, avoid those that suggest a lot of pre-preparation. For many dishes, particularly soups and stews, you really can just throw all the ingredients in. It can be nice to cook the onions beforehand, as the flavour is different to when you put them in raw, but experiment both ways as you may find you prefer one. It can also be good to brown meat to give it some colour, but again, this is not essential.

2. Prepare for slow cooking the night before

If you're short on time in the morning, prepare everything you need for your slow-cooked meal the night before, put it into the slow-cooker dish, cover and store in the fridge overnight. Ideally the dish should be as close to room temperature as possible, so get it out of the fridge when you wake up and leave it for 20 minutes before turning the cooker on. If you need to heat your dish beforehand, then put the ingredients in a different container and transfer them in the morning.

3. Choose cheap cuts

Slow cookers are great for cooking cheaper cuts like beef brisket, pork shoulder, lamb shoulder and chicken thighs. You can also use less meat, as slow cooking really extracts a meaty flavour that permeates the whole dish. Bulk up with vegetables instead.

4. Trim fat from meat before slow cooking

You don't need to add oil to a slow cooker – the contents won't catch as long as there's enough moisture in there. You don't need a lot of fat on your meat either. Normally when you fry meat, a lot of the fat drains away, but this won't happen in a slow cooker so trim it off – otherwise you might find you have pools of oil in your stew. Removing the fat will give you a healthier result, and it'll still be tasty.

5. Reduce liquid when using a slow cooker

Because your slow cooker will have a tightly sealed lid, the liquid won't evaporate so if you're adapting a standard recipe, it's best to reduce the liquid by roughly a third. It should just cover the meat and vegetables. Don't overfill your slow cooker, or it may start leaking out the top, and the food won't cook so well. Half to two-thirds full is ideal – certainly no more than three-quarters.

6. Use flour to thicken sauces

Just as the the liquid doesn't reduce, it also doesn't thicken. You can roll meat in a small amount of seasoned flour before adding it to the slow cooker or use a little cornflour at the end. If you want to do the latter, take a teaspoon or two of cornflour and mix it to a paste with a little cold water. Stir into your simmering slow cooker contents, then replace the lid.

7. Use the slow cooker low setting

Ginny has been working with slow-cookers for over a decade, and her advice is to use the 'Low' slow cooker settings as much as you can, finding that most dishes really benefit from a slow, gentle heat to really bring out the flavours. This also means you won't need to worry if you're heading out for the day – it'll take care of itself. "I think of it as my cook fairy making my dinner while I'm out," says Ginny. Optimize your culinary creations with ideal slow cooker temperature UK settings by checking your user manual.

8. Leave your slow cooker recipe alone

Slow cookers are designed to do their own thing, so you don't need to keep checking the contents. Every time you take the lid off it will release some of the heat, so if you keep doing this you'll have to increase the cooking time.

9. Add all ingredients at the start (most of the time)

Ideally you want to choose recipes where most, if not all, of the ingredients can be added at the beginning, leaving you free to do other things. However, in most cases, pasta, rice and fresh herbs will need to be added towards the end.

10. How long should I cook a slow cooker recipe?

If a dish usually takes:

• 15-30 mins, cook it for 1-2 hours on High or 4-6 hours on Low
• 30 mins – 1 hour, cook it for 2-3 hours on High or 5-7 hours on Low
• 1-2 hours, cook it for 3-4 hours on High or 6-8 hours on Low
• 2-4 hours, cook it for 4-6 hours on High or 8-12 hours on Low

Root vegetables can take longer than meat and other vegetables so put these near the heat source, at the bottom of the pot.
