Ingredients

Mushrooms:
½ cup butter
1 pound baby bella mushrooms, thick sliced
½ shallot, minced
1 tablespoon Worcestershire sauce
2 cloves garlic, minced
salt and pepper to taste

Burger:
1 ½ pounds ground beef
salt and pepper to taste
4 slices Swiss cheese
4 hamburger buns
butter for toasting buns
mayonnaise

Directions

For the mushrooms:
Heat ½ cup butter in a skillet over medium high heat. Add in 1 pound baby bella mushrooms, and ½ shallot,sauté for about 5 minutes.

Add in 1 tablespoon Worcestershire sauce, 2 cloves garlic, and salt and pepper to taste. Sauté another 2-3 minutes. Remove the mushrooms from heat and set aside.

For the burger:
Make 4 hamburger patties out of the 1 ½ pounds ground beef. Place two patties on the hot griddle or skillet and season with salt and pepper to taste. You can cook all of the hamburgers at the same time if your griddle will fit them all.

Cook the burgers for 2-3 minutes on each side, placing a slice of the 4 slices Swiss cheese on the patty once it’s been flipped. Once the patties are cooked, take 4 hamburger buns, butter them, and toast them on the same skillet.

Assemble from the bottom up. Start by spreading mayonnaise on the bottom and top bun, place the patty with the Swiss cheese on the bottom bun, spread a generous helping of the mushrooms on top of the patty, top the burger with the top bun.
