I'm so excited for grilling season. Last year I got my first grill and I am obessed with it. I've been thinking of all the things that I want to grill.
I really do love all the great vegan burger options on the market, but I wanted to create a whole food, plant-based vegan burger.
This Vegan Portobello Mushroom Burger recipe is perfect for anyone who isn't the biggest fan of store-bought vegan burgers.
how to make the portobello burgers
Start by cleaning the mushroom caps. Remove the stems and clean the mushroom caps with a damp cloth.
Next, make the marinade. In a shallow baking dish, whisk together balsamic vinegar, olive oil, steak seasoning, tamari and fresh rosemary.
Add the mushrooms to the marinade. Marinate the mushrooms for 10-15 minutes on each side.
Heat the grill over medium heat. When the grill is hot, brush the grates with oil.
While the mushrooms cook, use a brush to baste the reserved marinade frequently.
During the last few minutes of cooking, add vegan cheese slices to the mushrooms. For this recipe, I like to use Chao cheese.
Finally it's time to assemble the burgers.
I like to add lettuce, tomatoes, red onions and slices of avocado.
I like to grill the red onion slices on the grill along with the mushrooms. I love the flavor of grilled onions.
Since portobello mushrooms are thick and meaty, they make a great meatless burger option.
Whether your vegan, vegetarian or an omnivore, these portobello mushroom burgers are a great meatless burger option.
