Ingredients
  

For the lamb burgers
  • 600 g lamb mince 15-20% fat
  • 1/2 small onion very finely grated or minced
  • 2 tbsp fresh mint leaves finely chopped
  • 1 tbsp fresh parsley finely chopped
  • 1 tbsp Worcestershire sauce
  • 1 tsp Dijon mustard
  • 1 tsp fine sea salt
  • 1/2 tsp freshly ground black pepper
For the mint relish
  • 1 small bunch fresh mint leaves only, finely chopped
  • 1 small shallot or 1/4 red onion very finely chopped
  • 2 tbsp red wine vinegar or cider vinegar
  • 1 tsp caster sugar
  • 3 tbsp olive oil
  • Pinch of salt and pepper
To serve
  • 4 burger buns or brioche rolls
  • Little gem or iceberg lettuce leaves
  • Tomato slices
  • Red onion rings optional

Method
 

Step 1

  1. In a bowl, combine lamb mince, grated onion, chopped mint, parsley, Worcestershire sauce, Dijon mustard, salt and pepper. Mix gently until just combined.

Step 2

  1. Divide into 4 equal portions and shape into patties around 2 cm thick. Press a slight dimple in the centre of each. Chill for at least 30 minutes to firm up.

Step 3

  1. For the mint relish, whisk vinegar, sugar and a pinch of salt in a small bowl until the sugar dissolves. Stir in the chopped mint, shallot and olive oil. Adjust seasoning to taste and set aside.

Step 4

  1. Preheat the BBQ to medium-high direct heat. Clean and lightly oil the grates.

Step 5

  1. Grill the burgers for 5-7 minutes per side, turning once, until cooked through. Aim for a safe internal temperature of 75 C for minced meat burgers.

Step 6

  1. Lightly toast the buns on the grill for 30-60 seconds.

Step 7

  1. Assemble with lettuce, tomato slices and a generous spoonful of mint relish on top of each lamb burger. Serve immediately.

Notes

UK guidance recommends thoroughly cooking minced lamb burgers to at least 70-75 C in the centre for safety.
You can add crumbled feta to the burger mix for a richer flavour, or a pinch of chilli flakes to the relish for heat.
