Ingredients

• 1 can (15 oz) black beans, drained and rinsed
• 1 cup finely chopped cremini mushrooms
• ½ cup rolled oats
• ¼ cup finely diced onion
• 2 cloves garlic, minced
• 2 tablespoons soy sauce (or tamari for gluten-free)
• 1 tablespoon tomato paste
• 1 teaspoon smoked paprika
• ½ teaspoon ground cumin
• Salt and pepper to taste
• Vegetable oil for cooking
• 4 slices vegetarian cheese (optional)
• 4 burger buns
• Lettuce, tomato slices, pickles, and your favorite condiments for serving

Equipment

• Large mixing bowl
• Fork or potato masher
• Cast iron skillet or heavy non-stick pan
• Spatula (preferably metal for smashing)
• Measuring cups and spoons
• Knife and cutting board

Instructions

1. Prepare the bean mixture: In a large bowl, mash the black beans with a fork or potato masher until mostly smooth but still slightly chunky for texture.
2. Add vegetables and seasonings: Stir in the finely chopped mushrooms, diced onion, minced garlic, rolled oats, soy sauce, tomato paste, smoked paprika, cumin, salt, and pepper. Mix well until combined. Let the mixture sit for 5 minutes to allow the oats to absorb moisture and bind the mixture.
3. Preheat the skillet: Heat a cast iron skillet or heavy pan over medium-high heat. Add a little vegetable oil and let it get hot but not smoking.
4. Form and smash the patties: Divide the mixture into 4 equal portions. Place one portion onto the skillet and immediately press down firmly with a spatula to smash it thin. Hold the pressure for about 20-30 seconds to create a crispy crust.
5. Cook the patties: Cook the smashed patties for 3-4 minutes on the first side until the edges are crispy and browned. Flip carefully and cook for another 2-3 minutes.
6. Add cheese (optional): Place a slice of vegetarian cheese on each patty during the last minute of cooking. Cover the pan briefly to melt the cheese.
7. Toast the buns: Meanwhile, toast the burger buns lightly in a separate pan or toaster for extra flavor and texture.
8. Assemble the burgers: Place each patty on a toasted bun and top with lettuce, tomato, pickles, and your favorite condiments such as ketchup, mustard, or vegan mayo.
9. Serve immediately: Enjoy these delicious vegetarian smash burgers while hot for the best taste and texture.

Tips & Variations

For an even juicier burger, add a tablespoon of olive oil or vegan mayo to the patty mixture before cooking.

Feel free to experiment with your favorite spices — chili powder, cayenne, or fresh herbs like cilantro can add exciting layers of flavor. If you want a gluten-free option, swap the rolled oats for gluten-free oats and use gluten-free buns.

For a vegan version, simply use vegan cheese and buns, and swap soy sauce for tamari if needed. You can also add caramelized onions or sautéed peppers for extra savoriness.

Try serving your smash burger with a side of homemade fries or a fresh green salad. For more creative vegetarian dishes, check out our Vegetarian Tex Mex Recipes for Easy Weeknight Dinners or Vegetarian Swiss Chard Recipes for Healthy Meals.
