Mushroom Swiss Cheeseburger
Mushroom Swiss Cheeseburger
Ingredients
For the Beef Patties
- 1 1/2 pounds ground beef, 80/20 lean
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper, freshly ground
For the Sautéed Mushrooms & Onions
- 8 ounces cremini mushrooms, thinly sliced
- 1 yellow onion, medium, thinly sliced
- 2 tablespoons butter
- 1 teaspoon fresh thyme, chopped
- 1/4 teaspoon salt
- 1/8 teaspoon black pepper, freshly ground
For Assembly
- 4 hamburger buns, split
- 4 slices Swiss cheese
- 1/4 cup mayonnaise
- 2 tablespoons Dijon mustard
- 4 leaves green leaf lettuce, optional
- 1 tablespoon butter, for toasting buns, as needed
Instructions
- 1
In a large bowl, gently combine the ground beef, Worcestershire sauce, garlic powder, onion powder, 1 teaspoon salt, and 1/2 teaspoon black pepper. Be careful not to overmix, as this can make the patties tough. Divide the mixture into 4 equal portions and form them into patties, about 3/4 inch thick. Make a slight indentation in the center of each patty with your thumb to prevent them from bulging while cooking.

Heat 2 tablespoons of butter in a large skillet or cast-iron pan over medium-high heat. Add the sliced mushrooms and onions, fresh thyme, 1/4 teaspoon salt, and 1/8 teaspoon black pepper. Sauté, stirring occasionally, until the mushrooms are browned and the onions are softened and caramelized, about 8-10 minutes. Remove from the skillet and set aside.

In the same skillet, if needed, add 1 tablespoon of butter and toast the hamburger buns, cut-side down, until lightly golden, about 1-2 minutes. Remove the buns and set aside.

Increase the heat to medium-high. Place the beef patties in the hot skillet. Cook for 3-5 minutes per side for medium-rare to medium, or adjust cooking time to your desired doneness. During the last minute of cooking, place a slice of Swiss cheese on top of each patty and cover the skillet with a lid or foil to help the cheese melt.

While the patties are cooking, in a small bowl, whisk together the mayonnaise and Dijon mustard to create a creamy spread.

To assemble the burgers, spread the mayonnaise-Dijon mixture on both halves of each toasted bun. Place a lettuce leaf (if using) on the bottom bun, then top with a cheesy patty. Spoon a generous amount of the sautéed mushrooms and onions over the patty, and finally, place the top bun. Serve immediately.
