Ingredients
Scale
Marinade and Mushrooms
- 2 Tbsp olive oil
- 2 Tbsp soy sauce
- 1 Tbsp apple cider vinegar
- 1 tsp brown sugar
- 1/4 tsp oregano
- 1/4 tsp garlic powder
- 1/4 tsp onion powder
- 1 tsp smoked paprika
- Freshly cracked pepper (about 10 cranks)
- 2 portobello mushroom caps (about 1/2 lb total)
Buns and Toppings
- 2 buns
- 1 cup spring mix
- 1 tomato, sliced
- 1/4 red onion, sliced into rings
- 4 Tbsp mayonnaise
Instructions
- Prepare Marinade: In a small bowl, stir together the olive oil, soy sauce, apple cider vinegar, brown sugar, oregano, garlic powder, onion powder, smoked paprika, and freshly cracked pepper until well combined.
- Marinate Mushrooms: Remove the stems from the portobello mushrooms. Place the mushroom caps gill side up in a shallow dish. Pour some marinade into the gills, flip the mushrooms, and pour the remaining marinade over the other side. Let them marinate for 30 minutes, flipping occasionally to ensure even flavor absorption.
- Heat Grill: Preheat a grill or grill pan over medium to medium-high heat until hot and ready for cooking.
- Grill Mushrooms: Place the marinated mushrooms on the grill and cook for about 7 minutes on each side. Cook until mushrooms are soft and have released most of their liquid.
- Assemble Burgers: Place each grilled portobello mushroom on a bun and add your preferred toppings such as mayonnaise, sliced tomato, onion rings, and spring mix. Serve immediately and enjoy!
Notes
- You can save the mushroom stems to chop and add to an omelette or freeze with vegetable scraps to make vegetable stock.
- If you prefer, substitute mayonnaise with a vegan mayonnaise for a vegan option.
- For extra smoky flavor, consider adding a few drops of liquid smoke to the marinade.
- Use gluten-free buns if you require a gluten-free version.
- Marinating longer than 30 minutes is fine for deeper flavor but avoid marinating over 2 hours to preserve mushroom texture.
