Balsamic Caramelised Onions

Side Dish Recipes

These sweet and sticky onions are my favourite fried onions by far. They're great on burgers and hot dogs, with bangers and mash and as a topping to liven up any tart or quiche. The recipe is simple and slow but definitely well worth the wait!

I recommend you always use a good quality balsamic vinegar. Be prepared to pay around £8 to £15 for a 250ml bottle and make sure it has Aceto Balsamico on the label. 


1 Tbsp olive oil   

1 tsp soft brown sugar

250g white onions sliced and broken up   

1 Tbsp balsamic vinegar


Heat the olive oil over a medium heat. When the oil is hot, add the sugar & mix well with the oil. Stir in the onions with the oil. Add the balsamic vinegar & mix well. Keep stirring every 5 minutes until you get the shade of onions you require. I like mine mid to dark brown!

If you’re making the balsamic caramelised onions to use straight away, cook them as above. If you’re planning on using them as a topping on a baked tart, undercook them slightly and let the baking process finish them off.
