Nothing beats a burger hot off the grill! This one is topped with caramelized onions and melted Gruyère for an extra pop of flavor!!



  • 1 pound lean ground beef
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon coarse ground pepper
  • 1 teaspoon dried minced onion
  • 1/2 teaspoon seasoned salt
  • 34 oz Gruyère, (thinly sliced)
  • 3/4 cup caramelized onions
  • 34 brioche buns
  • 1/4 cup olive oil mayonnaise
  • 1 teaspoon Worcestershire sauce


  1. Preheat your grill to medium-high heat – about 400°F.
  2. Mix ground beef, Worcestershire, pepper, dried onion and salt in a small mixing bowl. Form into 3-4 burger patties.
  3. Cook burgers on a preheated grill for 3-5 minutes per side, depending on the desired doneness. The internal temperature should be 160° on an instant-read thermometer. 
  4. While the burgers are cooking mix the mayonnaise with the Worcestershire sauce. Refrigerate until ready to use.
  5. Turn grill to low and top each burger with a slice of cheese. Place brioche bun halves sliced side down on the grill away from the heat. Close the grill and let buns toast and cheese melt for 1-2 minutes.
  6. Remove everything from the grill. To assemble the burgers, spread the bottom half of each roll with the mayo mixture. Top with a burger patty and then add the caramelized onions. Top with remaining roll half and serve immediately.


If you haven’t previously made the caramelized onions, you’ll need to add about 45 minute to your prep time.
