Ingredients
- 1 pound Ground beef (80/20 blend)
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper
- 0.5 teaspoon Garlic powder
- 2 tablespoons Olive oil
- 1 tablespoon Butter
- 1 large Yellow onion, thinly sliced
- 8 ounces Mushrooms, sliced (e.g., cremini or button)
- 1 tablespoon Soy sauce
- 1 teaspoon Balsamic vinegar
- 4 slices Thick slices of crusty bread (e.g., sourdough or ciabatta)
- 4 slices Cheddar cheese, sliced
- 2 tablespoons Fresh parsley, chopped (optional, for garnish)
Directions
Step 1
In a large bowl, mix the ground beef with salt, black pepper, and garlic powder. Divide the mixture into 4 equal portions and shape each portion into a patty, slightly larger than the bread slices.
Step 2
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Cook the burger patties for 3-4 minutes per side, or until they reach your desired level of doneness. Remove the patties from the skillet and set them aside on a plate to rest.
Step 3
In the same skillet, add the remaining 1 tablespoon of olive oil and the butter. Once the butter is melted, add the sliced onion and cook for 4-5 minutes, stirring frequently, until softened and slightly caramelized.
Step 4
Add the sliced mushrooms to the skillet with the onions. Cook for an additional 5-6 minutes, stirring occasionally, until the mushrooms are golden and tender.
Step 5
Stir in the soy sauce and balsamic vinegar, cooking for 1 more minute to combine. Adjust seasoning with a pinch of salt and pepper, if needed. Remove the onion and mushroom mixture from the heat.
Step 6
Lightly toast the slices of crusty bread in a toaster or under the broiler until golden on top. Place each slice onto a serving plate.
Step 7
Top each slice of toasted bread with a burger patty. Place a slice of cheddar cheese on top of each patty while they are still warm, allowing the cheese to melt slightly.
Step 8
Spoon the onion and mushroom topping generously over each burger. Garnish with chopped fresh parsley, if desired.
Step 9
Serve immediately with your favorite sides or as a standalone meal.
