Ingredients
- 4 large portobello mushroom caps, cleaned and stems removed
- 3 tablespoons extra virgin olive oil
- 2 tablespoons balsamic vinegar
- 1 tablespoon soy sauce or tamari (for gluten-free)
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- Salt and black pepper, to taste
- Fresh lettuce leaves, washed and crisp
- 1 large tomato, sliced
- Thinly sliced red onion (optional)
- 4 slices cheese (cheddar, Swiss, or vegan cheese)
- 4 burger buns, toasted (whole wheat or gluten-free if preferred)
- Optional toppings: pickles, avocado slices, spicy mayo
Instructions
- Clean and prep mushrooms by wiping caps with a damp cloth and removing stems. (5 minutes)
- Make the marinade by whisking together olive oil, balsamic vinegar, soy sauce, minced garlic, dried oregano, salt, and pepper in a mixing bowl. (3 minutes)
- Place mushroom caps gill side up in the marinade and brush to coat generously. Let marinate for at least 15 minutes, up to 30 minutes. (15-30 minutes)
- Preheat grill or grill pan to medium-high heat (about 400°F). (5 minutes)
- Grill mushrooms gill side down for 5-6 minutes, then flip and add cheese slices. Grill another 4-5 minutes until tender and juicy. (10-12 minutes)
- Toast burger buns lightly on the grill or in a toaster. (2-3 minutes)
- Assemble burgers by layering lettuce, tomato slices, grilled mushroom with melted cheese, red onion, and optional toppings on toasted buns. Serve immediately. (5 minutes)
Notes
Do not overcook mushrooms to avoid mushy texture. Use tongs gently to keep caps intact. Add cheese in the last few minutes to melt perfectly. Marinate mushrooms for at least 15 minutes for best flavor. If no grill is available, use a grill pan or cast iron skillet on the stove. Toast buns lightly to prevent sogginess. Leftovers can be stored separately in the fridge for up to 2 days and reheated gently.
