American Mushroom and Swiss Burger

Ingredients

• 1 pound ground beef
• 8 ounces mushrooms sliced
• 4 slices Swiss cheese
• 4 whole hamburger buns toasted
• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 teaspoon salt
• 1/2 teaspoon black pepper freshly ground

Instructions

1. 1 In a large skillet, heat the olive oil and butter over medium heat. Add the sliced mushrooms and cook for 5-7 minutes until they are golden brown and tender. Set aside.
2. 2 Preheat a grill or grill pan over medium-high heat.
3. 3 In a large bowl, combine the ground beef with salt and freshly ground black pepper. Mix gently to combine.
4. 4 Divide the beef mixture into four equal portions and shape each into a patty about 3/4-inch thick.
5. 5 Place the patties on the preheated grill and cook for 4-5 minutes per side, or until they reach your desired doneness.
6. 6 During the last minute of cooking, place a slice of Swiss cheese on each patty and allow it to melt.
7. 7 Remove the patties from the grill and let them rest for a couple of minutes.
8. 8 To assemble the burgers, place each patty on the bottom half of a toasted hamburger bun. Top with sautéed mushrooms and cover with the top half of the bun.
9. 9 Serve immediately with your choice of sides.
