A juicy homemade beef burger topped with melted Swiss cheese, caramelized onions, sautéed mushrooms, fresh tomatoes, pickles, arugula, and a creamy Dijon sauce, all served on a buttery brioche bun.

Ingredients

For the Burgers

• 500 g ground beef (80/20)
• 1 tsp salt
• ½ tsp black pepper
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tbsp Worcestershire sauce (optional)

Instructions

1. Mix the ground beef with the salt, pepper, garlic powder, onion powder, and Worcestershire sauce. Divide into 4 patties.
