Tasty and lean beef burgers packed with sweet and sticky caramelised onions and rosemary - a Slimming World Friendly feast!

Course: Main Course
Servings: 6 burgers
Author: Katie Bryson
Ingredients
  • 1 red onion finely diced
  • fry light
  • 2 tsp soft dark brown sugar
  • 1 tsp sea salt flakes
  • 1 splash balsamic vinegar
  • 500 g lean beef mince (5% fat)
  • 1 tsp dried rosemary
  • salt and pepper to season
To serve
  • wholemeal sandwich thins
  • salad leaves
  • pickles
Instructions
  1. Make the caramelised onions first. Finely chop the onions, spray a frying pan with fry light and gently fry the onions with the brown sugar, sea salt and balsamic vinegar on a low heat for a few minutes to get it all coated. Give it a good stir.

  2. Tear off a 30cm squared piece of greaseproof paper, scrunch it up in your hand and run it under the cold tap. Shake off any excess water and then place it over the top of your onion mixture to completely cover it. Turn the heat down as low as it'll go and let the onions caramelise for about 10-15 mins. Keep an eye on them in case they start to catch! But they should be sticky and soft.

  3. Put your block of mince in a large mixing bowl and season with dried rosemary, salt and pepper. Using a fork give it all a good mix, breaking down the strands of minced beef. Finally add in the caramelised onion.

  4. Either using your hands or a simple burger press, form six equal sized burgers, pop on a plate and allow to chill in the fridge for a few hours.

  5. Heat a griddle pan on a medium heat, spray with fry light and gently cook the burgers for around 5 minutes, turn over for another 5 or until cooked through.

  6. Serve in wholemeal sandwich thins with lashings of salad and pickles. A side order of roasted Butternut Squash wedges always goes well too!
