• 1kg good-quality beef mince
  • 1 small onion, finely chopped
  • 2 garlic cloves, finely chopped
  • 2 tsp Dijon mustard
  • 1 tbsp Worcestershire sauce
  • Small handful chopped fresh flatleaf parsley
  • 1 large dill pickle gherkin, finely chopped
  • 1 large free-range egg yolk

To serve

  • 1 tbsp sunflower oil
  • 200g good melting cheese, such as Cheddar, Gruyère or Taleggio, sliced
  • 8 burger buns
  • 4 tbsp mayonnaise
  • 2 tsp Dijon mustard
  • Avocado, tomato and red onion, sliced
  • Lettuce leaves


  1. Place all the ingredients for the burgers in a large bowl. Season and mix well. Cover and chill in the fridge for 1 hour.
  2. Using wet hands, shape the mixture into 8 burgers. If you want to cook them straight away skip to step 4.
  3. If you are freezing them; place flat between sheets of baking paper in a rigid freezerproof container. Freeze for up to 3 months. When ready to use, defrost the burgers completely in the fridge; this will take 3-4 hours.
  4. Heat a griddle pan or barbecue to hot. Brush both sides of the burgers with oil and cook for 3-4 minutes each side or until well browned and cooked.
  5. Meanwhile, preheat the grill to medium hot. Top each burger with a slice of cheese and grill for 2 minutes until bubbling. Toast the burger buns until lightly golden.
  6. Mix the mayonnaise with the mustard and spread over the base of each bun. Add some tomato, lettuce and avocado slices, then the burger, red onion slices and the other half of the bun.
  7. Serve with a small bowl of ketchup and fries, if you like.
