Ingredients
Scale
- 1 lb 80/20 ground beef
- 4 brioche burger buns
- 8 oz cremini mushrooms, sliced
- 4 slices Swiss cheese
- 2 tbsp unsalted butter
- 1 clove garlic, minced
- 1 tsp kosher salt (plus black pepper to taste)
Instructions
- Step 1: Prepare the mushrooms by melting the butter in a skillet over medium heat. Add the minced garlic and sliced mushrooms, sautéing until the mushrooms are deeply browned and tender (about 6-8 minutes). Season with a pinch of salt and pepper, then remove from heat and set aside.
- Step 2: Form the ground beef into four 4-ounce patties, slightly wider than the buns. Season both sides of the patties generously with the remaining kosher salt and black pepper.
- Step 3: Cook the patties on a hot grill or skillet to your desired doneness (typically 4-5 minutes per side for medium). During the last minute of cooking, place one slice of Swiss cheese on top of each patty to melt.
- Step 4: While the cheese is melting, lightly toast the burger buns (either on the grill or under a broiler). Spread 1 tablespoon of mayonnaise on the top and bottom halves of each toasted bun.
- Step 5: Assemble the burger by placing the cheeseburger patty on the bottom half of the bun. Top the melted Swiss cheese with a generous portion of the sautéed mushroom and garlic mixture.
- Step 6: Place the top bun over the mushrooms and serve immediately.
Notes
- To maintain flavor and texture, store leftover cooked patties and the mushroom mixture in separate, sealed containers in the refrigerator for up to 3 days.
- Reheat patties gently in a 300°F oven for about 10 minutes to prevent drying out; warm the mushroom topping briefly in a separate skillet to ensure it maintains its rich, savory texture.
- The richness of the Swiss and beef is perfectly balanced by serving alongside a crunchy side like dill pickle chips or a light, vinegary coleslaw.
- For the best texture in Step 1, avoid overcrowding the skillet when sautéing the mushrooms; deep browning (not steaming) is crucial for developing the rich umami flavor that defines this burger.
