The Best Grilled Portobello Mushroom Burgers
These Portobello mushroom burgers are as satisfying as they are healthy. With their meaty texture and rich, earthy flavor, they make the perfect canvas for all your favorite toppings. Let’s get started!

Ingredients:
- 4 large Portobello mushroom caps
- 1/2 cup balsamic vinegar
- 1/4 cup olive oil
- 2 cloves garlic, minced
- 1 teaspoon dried Italian herbs (oregano, basil, thyme)
- Salt and pepper to taste
- 4 whole wheat burger buns
- Fresh spinach or arugula
- Slices of tomato
- Avocado or guacamole (optional)
- Cheese slices (optional)
Instructions:
- Begin by cleaning the Portobello mushroom caps gently with a damp cloth to remove any dirt. Remove the stems and gills if desired, although this is optional.
- In a bowl, whisk together the balsamic vinegar, olive oil, minced garlic, Italian herbs, salt, and pepper. This marinade will infuse the mushrooms with flavor.
- Place the mushrooms in a shallow dish and pour the marinade over them. Ensure the mushrooms are well-coated. Cover and let them marinate for at least 30 minutes, or up to 2 hours for a richer taste.
- Preheat your grill to medium-high heat. Once hot, place the marinated mushrooms on the grill, gill side down. Grill for about 5-7 minutes.
- Carefully flip the mushrooms and continue grilling for another 5-7 minutes, checking for nice grill marks and a tender texture.
- While the mushrooms are grilling, toast the whole wheat burger buns on the grill until golden brown.
- Assemble your burger by placing a grilled Portobello cap on the bottom half of the bun. Top it with fresh spinach, a slice of tomato, avocado, and cheese if you like extra creaminess.
- Finish off by placing the top half of the bun on your masterpiece. Enjoy your flavorful grilled Portobello mushroom burger!
