    • Total time
  • Easy
  • Serves 8
Slowly, slowly caramelised onions with a hint of balsamic vinegar


  • 1tsp Oil

700g Onions, finely sliced (use red for a sweeter taste)

  • 1tbsp Caster Sugar
  • 1tsp Salt
  • pinch Pepper
  • 2tbsp Balsamic Vinegar


  • STEP 1
    Put all the ingredients apart from the vinegar in a slow cooker - or a very low oven or aga (50degreesC)
  • STEP 2
    Let it cook all day - and all night if it needs it - untill the onions are soft and dark brown and reduced. If it is crisping the heat is too high. You may need to stirr it occasionally - but i usually just leave it.
  • STEP 3
    Cook for the last half hour without a lid - to help it dry out a bit.
  • STEP 4
    Stirr in the balsamic vinegar. Done!
  • STEP 5
    I serve this with Lamb or Beef - but I also keep pots of it in the freezer to top homemade bread - or to put on puff pastry with brie.
