Ingredients
Scale
- 4 large portobello mushroom caps, cleaned and stems removed
- 3 tablespoons extra virgin olive oil
- 2 tablespoons balsamic vinegar
- 3 cloves garlic, minced (or garlic powder)
- 1 teaspoon smoked paprika
- 1 teaspoon dried oregano
- Salt and freshly ground black pepper, to taste
- 4 slices cheese (provolone, mozzarella, cheddar, or pepper jack)
- 4 burger buns, lightly toasted (brioche recommended)
- Optional toppings: lettuce, tomato slices, red onion rings, pickles, or favorite burger condiments
Instructions
- Prepare the marinade: In a medium bowl, whisk together olive oil, balsamic vinegar, minced garlic, smoked paprika, dried oregano, salt, and black pepper until well combined.
- Clean and prep the mushrooms: Gently wipe the portobello caps with a damp paper towel to remove dirt. Remove the stems by twisting them off.
- Marinate the mushrooms: Place the mushroom caps in the bowl with the marinade, turning to coat both sides evenly. Let sit for at least 15 minutes, up to 30 minutes for deeper flavor.
- Preheat your grill or grill pan over medium-high heat.
- Grill the mushrooms: Place marinated mushrooms gill-side down on the grill. Cook for 5-7 minutes, then flip carefully.
- Add the cheese: Immediately place a slice of cheese on each mushroom cap after flipping. Close the grill lid or cover the pan to melt the cheese for 2-3 minutes.
- Toast the buns lightly on the grill for 1-2 minutes until golden and slightly crisp.
- Assemble the burgers: Place each cheesy mushroom cap on the bottom bun, add desired toppings, then crown with the top bun.
Notes
Marinate mushrooms for at least 15 minutes but no longer than 30 to avoid sogginess. Use tongs gently to flip mushrooms only once. Rest mushrooms for a few minutes after grilling to retain juiciness. For dairy-free, use plant-based cheese or skip cheese. For gluten-free, use gluten-free buns or lettuce wraps.
