My caramelised onions are the perfect accompaniment to steak

If you read my ‘Amazing steak burger recipe ideal for the weekend’ last week, you may remember that I promised to upload my favourite caramelised onion recipe as the two went so well together. If you’re a fan of onions and want something different than the usual fried rings, this goes well with a steak and amazingly well with that steak burger.

Have them on the side with a salad or on the burger as a relish, the choice is up to you but the overall effect is the same. Delicious sweet oniony goodness with very little effort or preparation. That’s the perfect recipe as far as I’m concerned!


  • 2 tablespoons vegetable oil
  • 2 medium onions, thinly sliced
  • 1/2 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 2 tablespoons tomato puree
  • 3 tablespoons Worcestershire sauce
  • 2 tablespoons white wine vinegar
  • 2 tablespoons butter
  • 1 tablespoon light brown sugar


  1. Heat the oil in a pan over a medium heat and add the onions. Season to taste. Cook for around 10 minutes until they begin to brown.
  2. Add the tomato puree and cook in for a minute. Then add the Worcestershire sauce, vinegar, butter and brown sugar. Make sure to mix thoroughly and collect all the little bits of onion as you go. Cook for around 15 minutes or until caramelised.
  3. Add a tablespoon of water, mix until combined and allow to cool.

It’s a very simple but very effective recipe that delivers awesome onions with very little effort. It works with white onions as long as they are fresh or use red onions for a little more sweetness.

You can make this recipe days in advance and keep in the refrigerator in a plastic container. Allow to come up to temperature or heat them slightly before serving. Don’t freeze them though as it doesn’t work.
