Black Bean Burgers on Portobello Buns
Ingredients
- 1 can 15 oz black beans, rinsed and drained
- 1/2 cup gluten-free breadcrumbs
- 1/4 cup chopped onion
- 1 clove garlic minced
- 1 teaspoon smoked paprika
- 1/2 teaspoon cumin
- Salt and pepper to taste
- 4 large portobello mushrooms stems removed
- Olive oil for cooking
- Your favorite toppings for serving e.g., avocado, tomato, lettuce
Instructions
- In a medium bowl, mash the black beans with a fork until they are partially broken down.
- Stir in the breadcrumbs, onion, garlic, smoked paprika, and cumin. Season with salt and pepper.
- Form the mixture into four patties.
- Brush the portobello mushrooms with olive oil and season with salt and pepper. Grill or bake for 5-7 minutes per side, or until tender.
- Heat a lightly oiled skillet over medium heat. Cook the black bean patties for 4-5 minutes per side, or until golden brown and cooked through.
- Serve the black bean burgers on the portobello mushroom buns with your favorite toppings.
Tips for Success
- Dry your mushrooms well. Excess moisture can make the “buns” soggy.
- Firm up your patties. If your mixture feels too wet, add more oats or chill it before cooking.
- Spice it up. Add chopped jalapeño or hot sauce for a kick.
- Grill option: Both the patties and mushrooms can be grilled for extra smoky flavor.
