This decadent, incredibly juicy burger recipe can be easily whipped up on a weeknight, but is impressive enough for company.


Ingredients

  • 3 tbsp unsalted butter , divided
  • 1 Spanish onion , sliced into rounds
  • 1 cup beef broth
  • 500 g lean ground beef
  • 1 tbsp finely chopped thyme
  • 2 tsp Dijon mustard
  • 4 slices Gruyère cheese
  • 4 brioche burger buns , split
  • 1/2 cup mayonnaise
  • 1 tbsp chopped parlsey
  • 1 cup arugula , (optional)

Instructions

  1. Melt butter in a large frying pan over medium. Reserve 1 tbsp in a small bowl. Add onion to pan and cook, stirring often, until softened, about 8 min. Pour in broth and continue cooking, stirring occasionally, until onion is very soft, about 15 min.

  3. Preheat barbecue or grill pan on medium. Oil grill. Cook patties, lid closed, until cooked through, 5 to 6 min per side. Melt a slice of cheese on each patty, lid closed, 2 min.
  4. Brush reserved 1 tbsp butter on insides of brioche buns, then place on grill to toast, about 2 min.
  5. Meanwhile, stir mayo with parsley and remaining 3/4 tsp pepper in a small bowl.
  6. Spread bottom buns with pepper mayo. Layer with patties, sautéed onions and arugula. Sandwich with top bun.
