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

Directions

Step 1

Clean the Portobello mushroom caps with a damp paper towel and remove the stems.

Step 2

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.

Step 3

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.

Step 4

While the mushrooms marinate, peel and slice the onion into thin rings.

Step 5

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.

Step 6

Slice the tomato into thin rounds and prepare the lettuce leaves by rinsing and patting them dry. Set aside.

Step 7

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.

Step 8

Toast the burger buns lightly on a grill or in a skillet for added texture and flavor.

Step 9

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.

Step 10

Serve immediately with your favorite sides like French fries, coleslaw, or a simple salad!
