Grilled Portobello Mushroom Burgers

Hearty and flavorful grilled portobello mushroom burgers that are a perfect vegetarian alternative to traditional beef burgers.

Ingredients

Scale
  • 4 large portobello mushroom caps
  • 1/4 cup balsamic vinegar
  • 2 tablespoons olive oil
  • 1 tablespoon soy sauce
  • 2 cloves garlic, minced
  • Salt and black pepper to taste
  • 4 burger buns
  • 4 slices provolone or mozzarella cheese (optional)
  • Lettuce leaves
  • Tomato slices
  • Red onion slices
  • Condiments of choice (mayonnaise, mustard, etc.)

Instructions

  1. Clean the portobello mushrooms and remove the stems.
  2. In a small bowl, whisk together balsamic vinegar, olive oil, soy sauce, garlic, salt, and pepper.
  3. Place mushrooms in a shallow dish and pour the marinade over them. Let marinate for 15–30 minutes, flipping once halfway through.
  4. Preheat grill to medium-high heat.
  5. Grill mushrooms for about 5–7 minutes per side, or until tender and grill marks appear. Add cheese slices during the last minute of grilling, if using.
  6. Toast the burger buns on the grill for 1–2 minutes until golden.
  7. Assemble the burgers by placing a grilled mushroom on each bun bottom, then topping with lettuce, tomato, onion, and desired condiments. Cover with bun tops.
  8. Serve hot and enjoy.

Notes

  • Marinate mushrooms longer for deeper flavor.
  • Use vegan cheese or skip cheese for a vegan version.
  • Customize toppings as desired.
