Sugar- Free Caramalized Onion Jam

(Laura's onion Jam)

This recipe is purely based on my mum's sugar laden caramelised onions that I grew up having– Just a few ingredient changes and she’s a keto dream!

Patience is key with this recipe don’t pull the onions off the heat until the are really softened all the way through and then they really are pure perfection! Perfect in a savoury tart , make a big batch and keep them in a jar in the fridge- I have had a jar last over a month, it has a great shelf life.

My favourite ways to use the onion jam are on a keto pizza, paired with steak or on Keto crackers- They can be found here
