Ingredients

Scale
  • 4 large portobello mushroom caps, cleaned and stems removed
  • 1/4 cup olive oil (extra virgin preferred)
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon soy sauce (Kikkoman recommended)
  • 3 cloves garlic, minced
  • 1 teaspoon dried oregano
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 8 oz creamy cheese (mozzarella, provolone, Havarti, sliced or shredded)
  • 4 burger buns, toasted (brioche or whole wheat)
  • Optional fresh toppings: lettuce, tomato slices, red onion rings, pickles
  • Optional condiments: burger sauce, mayo, mustard

Instructions

  1. Gently wipe each portobello mushroom cap with a damp cloth to remove any dirt. Remove the stems carefully by twisting them off. (Approx. 5 minutes)
  2. In a mixing bowl, whisk together 1/4 cup olive oil, 2 tablespoons balsamic vinegar, 1 tablespoon soy sauce, minced garlic, 1 teaspoon dried oregano, salt, and freshly ground black pepper to make the marinade. (Approx. 5 minutes)
  3. Place mushroom caps in the bowl or a shallow dish, gill side up, and pour the marinade over them. Let them soak for at least 20 minutes, turning once halfway through. (Up to 1 hour for better flavor)
  4. Preheat grill or grill pan to medium-high heat (about 400°F). Lightly oil the grates or pan to prevent sticking.
  5. Place mushrooms gill side down on the grill. Cook for 5-7 minutes until char marks form. Flip carefully with tongs, add slices or shreds of creamy cheese on top, cover to help cheese melt, and grill for another 3-5 minutes until mushrooms are tender and cheese is bubbly.
  6. While mushrooms grill, toast buns lightly on the grill or in a toaster. Slice any fresh toppings you want to add.
  7. Assemble burgers by placing grilled mushroom caps with melted cheese on the bottom half of each bun. Add fresh lettuce, tomato, onion, and preferred condiments. Top with the other half of the bun.
  8. Serve immediately while hot to enjoy the creamy cheese and smoky mushroom flavor at their peak.

Notes

If mushrooms seem dry, brush with extra olive oil before grilling. Avoid overcooking to keep mushrooms juicy. Add cheese after flipping to melt without burning. Toast buns during last few minutes of grilling. For dairy-free, use plant-based cheese; for gluten-free, use gluten-free buns or lettuce wraps. Mushrooms can be roasted in oven at 425°F for 15-20 minutes as an alternative.
