  • 2 kg onions (or 4 pounds, chopped)
  • 750 g apples (or 1-2 pounds, chopped - I used Gala/Braeburn)
  • 1-2 tbsp balsamic vinegar
  • 1/4 cup coconut oil (melted)
  • 2-3 tbsp honey


  1. Toss all ingredients in slow cooker and place on low for 8-10 hours.

Recipe Notes

You don’t have to chop your onions and apples finely, as it won’t affect the final result.

If you want a jammier texture, leave it longer but take the lid off about an inch whilst cooking.
