For the Burgers:

  • 1 1/2 pounds 90% lean ground beef
  • 1 1/2 teaspoons Worcestershire sauce
  • 1 1/2 teaspoons Montreal steak seasoning
  • 1 clove garlic crushed

For Serving:

  • 4 slices Swiss cheese
  • 4 buns
  • 1/2 cup caramelized onions See Recipe


  • Preheat a grill to medium-high heat.
  • Mix together all ingredients for the burgers in a large bowl. Shape the mixture into 4 equal patties.
  • Cook the burger patties until they’re done to your preference, about 7 to 9 minutes per side, flipping once.
  • When they’re almost done, put 1 slice of cheese on each burger, cover the grill, and let the cheese melt.
  • If desired, split the buns in half and toast them (cut side down) on the grill for a couple minutes.
  • To serve, put each burger on a bun and top each with 2 tablespoons caramelized onions. (See Note)


  • See our post on how to easily cook caramelized onions.
  • Don't overwork the beef mixture or the burgers can become tough and chewy. Everything should be just combined.
  • Don't be tempted to press the burgers down on the grill or keep flipping them. Let them cook without constantly moving them.
