Caramelised onions, a great way to get one of your five a day in a tasty way.

Caramelised onions in the slow cooker for kids


6 -8 Red Onions (any onions can be used)

3 tablespoons Butter OR Olive Oil

Pinch of Salt (Optional)

Pinch of Sugar (optional)


Large Knife

Chopping Board

Slow Cooker on low


10 hours for a bite

Further couple of hours with the lid open to get jammier texture.

Caramelised onions are a great way to get one of your five a day in a tasty way. We use red onions as they are naturally sweeter than other types, however any can be used. If you are new to onions, chop them up small, add the sugar if you like and cook them for longer, the more sugar you add, the sweeter they will be, however they will also be less healthy and bad for your teeth. The onions will develop a natural sweet taste after cooking without the sugar. If you already like onions, you will not need the sugar and if you cook them for the recommended time, they will have a slight bite. Beware, onions can make you cry, breathing through your mouth, not your nose can help. You can cook them in a frying pan on a very low heat if you do not have a slow cooker, but they must be stirred every 5-10 minutes and left with a lid on. This way they will take just over an hour to be ready.

1. Peel the onions and chop into slices

2. 1/2 to ¾ fill the slow cooker with onions

3. Drizzle the olive oil or butter for a creamier taste over the onions

4. Salt and sugar if desired and mix with the onions

5. Put on the lid and turn on to low

6. Leave for 10 hours

7. Return, stir, taste and decide if you wish to cook them longer

8. Leave the lid slightly ajar and stir every hour after until they are the texture you desire

You can then eat the onions or let them cool and freeze them. I would advise putting them into portion size containers and freezing, not in one large one or it will all need defrosting and you cannot then freeze again.

Caramelised onions can be eaten in sandwiches, in pasta, on toast with anything you wish to try, the only thing stopping you is your imagination.
