Everyone needs a good burger recipe up their sleeves. And this one is a proper grown-up version. Makes 4 burgers.
- 2 slices white bread
- 50 ml milk
- 500 grams minced beef
- 1 tsp mustard
- 1 tsp onion powder
- 1/2 tsp garlic powder
- salt and pepper
- 1 large onion
- 1 tsp sugar
- 25 grams butter
- 4 tbsp mayonnaise
- 4 tsp Dijon mustard
- block of reblochon cheese (if you can’t find reblochon or want something milder, try gruyere instead)
- 4 buns of your choice
- Take the crusts off the bread and tear into small pieces. Soak the bread in a little milk for a few minutes until soft – squeeze out any excess milk.
- Add the minced beef, mustard, onion and garlic powder and a good grind of salt and pepper to a bowl with the soaked bread. Mix it all together thoroughly with your hands.
- Shape into 4 burger patties and set aside.
- Finely slice the onion and add it to a frying pan with the butter and sugar. Gently fry the onion until it’s nicely caramelised, and set aside.
- Mix the mayonnaise and French mustard together is a small bowl and set aside.
- Heat a large frying pan (or your BBQ to around 200 degrees C) and cook your burgers, flipping every couple of minutes, until almost cooked through.
- Slice the cheese and top each burger with it – cover just until the cheese starts to melt.
- Meanwhile, halve the buns lengthwise and briefly grill the inside of them so they’re slightly charred.
- To assemble: spread a layer of the mustard-mayo mix on the bottom half of the bun. Top with a burger with the melted cheese on it, and add a spoonful of the caramelised onion mixture. Top with the other half of the bun and serve immediately.
