This portobello mushroom burger is a delicious and hearty alternative to traditional beef burgers. The meaty texture of the portobello mushrooms makes them a perfect substitute, while the olive oil and balsamic vinegar marinade adds a rich, savory flavor. Topped with fresh lettuce and tomato, and optionally, a slice of cheese, this burger is sure to satisfy both vegetarians and meat-lovers alike.
If you don't usually cook with portobello mushrooms, you might need to look for them in the produce section of your supermarket. They are larger and meatier than regular mushrooms. Balsamic vinegar is another ingredient that might not be in your pantry; it can usually be found in the vinegar or salad dressing aisle.
Ingredients For Portobello Mushroom Burger Recipe
Portobello mushrooms: Large, meaty mushrooms that serve as the burger patty.
Olive oil: Used to marinate the mushrooms and add richness.
Balsamic vinegar: Adds a tangy, slightly sweet flavor to the marinade.
Garlic powder: Provides a subtle garlic flavor to the mushrooms.
Burger buns: The base and top for your burger, toasted for extra texture.
Cheese: Optional, adds creaminess and flavor to the burger.

Technique Tip for This Recipe
When preparing portobello mushrooms for grilling, make sure to remove the gills on the underside of the caps. This can be done easily with a spoon. Removing the gills not only helps the mushrooms cook more evenly but also prevents them from becoming too soggy, ensuring a better texture for your burger.
