Ingredients
Scale
Marinade
- 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)
Main
- 2 portobello mushroom caps (about 1/2 lb. total)
- 2 buns
Optional Toppings
- 1 cup spring mix
- 1 tomato, sliced
- 1/4 red onion, sliced into rings
- 4 Tbsp mayonnaise
Instructions
- Prepare the Marinade. In a small bowl, stir together olive oil, soy sauce, apple cider vinegar, brown sugar, oregano, garlic powder, onion powder, smoked paprika, and freshly cracked pepper until well combined.
- Marinate the Mushrooms. Remove the stems from the portobello mushrooms. Place the mushrooms gill sides up in a shallow dish. Pour some marinade over the gills, then flip and pour the rest over the top. Let marinate for 30 minutes, flipping occasionally to absorb flavors evenly.
- Heat the Grill. Preheat a grill or grill pan over medium to medium-high heat until hot.
- Grill the Mushrooms. Place the marinated mushrooms on the grill and cook for about 7 minutes on each side, until the mushrooms are soft and have released most of their liquid.
- Assemble the Burgers. Place the grilled mushrooms on buns and add preferred toppings such as mayonnaise, sliced tomato, onion rings, and spring mix or lettuce. Serve immediately.
Notes
- You can save the mushroom stems to chop and add to an omelette or freeze with vegetable scraps for making stock later.
- For a vegan option, substitute mayonnaise with vegan mayo or avocado spread.
- If you don’t have a grill, a grill pan or skillet over medium heat works well.
- Allow mushrooms to marinate for the full 30 minutes to maximize flavor.
- Toasting the buns adds nice texture and enhances the burger experience.
