This slow cooker caramelised apple onion recipe is an accompaniment that can take your meals to the next level! Easy to make and flavourful without much, this paleo condiment is a must-make in your home.

I’ve made caramelised onions on this blog before, but I wanted to do something a little different this time. My next thought was adding a fruit to it – if you’re a regular reader, you’ll see that I LOVE adding fruits to savoury meals (makes me feel a little more 5* chef-y).

So, I poured some apples and onions in my slow cooker, gave it a toss and let it be overnight. I woke up to a sweet-smelling aroma and thanked God for good food.

How to make Caramelized Onion Recipe: Stove top vs Slow Cooker

Caramelised onions are very easy to make. You can choose to make them on your stove top or with a slow cooker. 

The benefits of using a slow cooker is that you can literally pour everything in without worrying about the food burning. You can set it and forget it. 

With the stovetop, you get the results quicker but you also have to stir the onions for the duration of the cooking process so they don’t burn

I prefer using a slow cooker method as I think the onions come out more buttery. However, the stove top does add a nice crispiness to the onions. 

Stove top caramelised onions are probably best used in burgers and with slaws. Slow cooker caramelised onions is best used in stuffings.

You will know when onions are caramelised by the colour change. They will turn a deep dark brown colour and become softer and jammier.

How to make an onion Chutney

A way to take this paleo caramelized onions and apples recipe to the next level is by making it into an apple onion chutney or apple onion jam. 

The texture is perfect once it’s slow cooked, all you need to do is add some spices like curry powder and cinnamon, some apple cider vinegar or lemon juice. 

To make it jammier, in the last 2/3 hours of cooking,  just leave the lid off a bit whilst cooking.

FAQ’s about caramelised onions:

Can you freeze caramelised onions?

Yes! Freezing caramelised onions is the easiest and longest way to store and preserve them. They will last for 3 or 4 months in the freezer and only 3 or 4 days in the fridge. 

How do you reheat caramelised onions?

The best way to reheat caramelised onions is on the stove top. This way, you have the best of both worlds when you make it in the slow cooker as it crisps up on the stove. However, microwaving for 3-4 minutes from frozen is also good.

Caramelised onions are keto friendly and vegan so this is definitely a great all round condiment!
