1 lb. brick or Reminisce Angus Beef
2 cups finely chopped mushrooms (such as cremini or button mushrooms)
1 small onion, finely chopped
2 cloves garlic, minced
2 tablespoons olive oil
1 tablespoon Worcestershire sauce
1 teaspoon dried thyme
1 teaspoon dried oregano
Salt and pepper to taste
Your favorite burger toppings (lettuce, tomato, onion, cheese, etc.)
Condiments (ketchup, mustard, mayonnaise, etc.)
Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the chopped mushrooms and cook, stirring occasionally, until they release their moisture and turn golden brown, about 5-7 minutes. Transfer the cooked mushrooms to a plate and set aside.
Cook Onion and Garlic
In the same skillet, add the remaining tablespoon of olive oil. Add the chopped onion and minced garlic and cook until softened, about 3-4 minutes.
In a large mixing bowl, combine the ground beef, cooked mushrooms, cooked onion, minced garlic, Worcestershire sauce, dried thyme, dried oregano, salt, and pepper. Use your hands or a spoon to mix everything together until well combined.
Divide the mixture into 4 equal portions and shape each portion into a burger patty, about 1/2 to 3/4 inch thick. Make a slight indentation in the center of each patty with your thumb to prevent them from bulging during cooking.
Preheat your grill or skillet over medium-high heat. Cook the burger patties for about 4-5 minutes per side, or until they reach your desired level of doneness (160°F/71°C for medium). If adding cheese, place a slice on top of each patty during the last minute of cooking to melt.
Toast the burger buns on the grill or in a toaster. Place a cooked burger patty on the bottom half of each bun. Top with your favorite burger toppings and condiments. Cover with the top half of the bun.
Serve the mushroom burgers immediately with your favorite side dishes and enjoy!
