This rich and flavorful burger, featuring perfectly seasoned beef, gooey Swiss cheese, and savory grilled mushrooms and onions, is a must-try! Don't forget to pick up a bottle of @countrybobinc All-Purpose Sauce at @Walmart to take it to the next level.
Heat a large skillet over medium heat. Add olive oil and butter, letting the butter melt completely.
Add the diced onions and cook for about 2 minutes until they begin to soften.
Stir in the sliced mushrooms and continue to cook for 5-7 minutes until the mushrooms are tender and browned.
Add the minced garlic and salt, pepper, and garlic rub. Cook for another minute, stirring frequently.
Pour in Country Bob’s All-Purpose Sauce, stirring well to coat the mushrooms and onions. Let simmer for 1-2 minutes, then remove from heat and set aside.
Preheat a grill or skillet over medium-high heat.
Season both sides of each patty with the salt, pepper, and garlic rub.
Cook the patties for about 3-4 minutes per side for medium doneness, or adjust to your preferred level.
In the last minute of cooking, place a slice of Swiss cheese on each patty and cover the grill or pan to help the cheese melt.
Spread a thin layer of mayonnaise on the bottom half of each toasted brioche bun.
Place the cooked burger patty with melted Swiss cheese on top.
Generously spoon the grilled mushroom and onion mixture over the patty.
Add the top bun and serve immediately.
