Mushroom Burgers Recipe
Whether hosting a summer backyard barbecue or simply craving a satisfying plant-based meal, these portobello mushroom burgers are a fantastic choice.
They offer a hearty and flavorful option that is sure to impress even the meat eaters!
Large, “meaty” portobello mushrooms are brushed with BBQ sauce (use your favorite kind) and grilled to perfection in this mushroom burger recipe.
Serve the plant-based burgers with your favorite toppings and sides in a toasted sesame seed bun.
We used crisp lettuce, juicy tomato, tangy red onion rings, and sliced pickles and served the mushroom burgers with potato chips.
If dairy isn’t a concern for you, add a slice of cheese to your burger – Mozzarella and Cheddar work well, and earthy goat cheese is also delicious.
