Recipe Information
Ingredients
- 4 large caps Portobello mushrooms
- 4 tablespoons Olive oil
- 2 tablespoons Balsamic vinegar
- 1 tablespoon Soy sauce
- 3 cloves Garlic
- 4 pieces Burger buns
- 4 slices Cheddar cheese
- 1 large Yellow onion
- 2 tablespoons Butter
- 4 leaves Lettuce
- 1 large Tomato
- 4 tablespoons Mayonnaise
- 0.5 teaspoon Salt
- 0.5 teaspoon Black pepper
Instructions
Clean the Portobello mushroom caps with a damp paper towel and remove the stems.
In a small bowl, whisk together 3 tablespoons of olive oil, balsamic vinegar, soy sauce, minced garlic, salt, and black pepper to make the marinade.
Place the mushroom caps in a shallow dish and pour the marinade over them, making sure all caps are evenly coated. Let them marinate for 15 minutes, flipping halfway through.
While the mushrooms marinate, peel and slice the onion into thin rings.
Heat 1 tablespoon of olive oil and 2 tablespoons of butter in a skillet over medium heat. Add the onion slices and cook, stirring occasionally, until they are golden brown and caramelized, about 10-12 minutes. Set aside.
Slice the tomato into thin rounds and prepare the lettuce leaves by rinsing and patting them dry. Set aside.
Heat a grill pan or skillet over medium-high heat. Cook the marinated mushrooms for 4-5 minutes per side, or until they are tender and slightly charred. In the last minute of cooking, place a slice of cheddar cheese on each mushroom cap and cover the pan to allow the cheese to melt.
Toast the burger buns lightly on a grill or in a skillet for added texture and flavor.
To assemble the burgers, spread 1 tablespoon of mayonnaise on the bottom half of each bun. Layer with a lettuce leaf, a slice of tomato, the cheesy mushroom cap, and a generous serving of caramelized onions. Top with the other half of the bun.
Serve immediately with your favorite sides like French fries, coleslaw, or a simple salad!
