Ingredients

  • 1 can (15 oz) black beans, drained and rinsed
  • 1 cup finely chopped cremini mushrooms
  • 1/2 cup rolled oats
  • 1/4 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
  • 1/2 teaspoon ground cumin
  • 1/4 teaspoon black pepper
  • Salt, to taste
  • 2 tablespoons olive oil, for cooking
  • 4 burger buns, toasted
  • 4 slices cheese (vegan or regular, optional)
  • Lettuce leaves, tomato slices, pickles, and red onion, for toppings
  • Condiments like mayo, ketchup, mustard, or your favorite sauce

Equipment

  • Large mixing bowl
  • Food processor (optional, for finer texture)
  • Large skillet or griddle
  • Spatula or sturdy burger press
  • Measuring cups and spoons
  • Knife and cutting board
  • Plate lined with paper towels (for resting patties)

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 everything thoroughly. If you prefer a smoother texture, pulse the mixture briefly in a food processor.
  3. Form the patties: Divide the mixture into 4 equal portions and gently shape each into a loose ball. Do not compact too tightly, as you want the patties to smash well.
  4. Heat the skillet: Heat 1 tablespoon of olive oil in a large skillet or griddle over medium-high heat until shimmering.
  5. Smash and cook the patties: Place one ball of the mixture on the hot skillet. Using a spatula or burger press, firmly press down to flatten the ball into a thin patty about 1/2 inch thick. Cook for 3-4 minutes until the edges are crispy and browned.
  6. Flip and add cheese: Carefully flip the patty and cook for another 2-3 minutes. If using cheese, place a slice on top now and cover the skillet with a lid to help it melt.
  7. Repeat: Remove the cooked patty to a plate lined with paper towels to drain excess oil. Repeat the smashing and cooking process with the remaining patties, adding olive oil as needed.
  8. Assemble your smashburger: Toast your burger buns lightly. Spread your favorite condiments on the buns, then layer with lettuce, tomato slices, the vegetarian patty, pickles, and red onion.
  9. Serve immediately: Enjoy your vegetarian smashburger hot for the best texture and flavor!

Tips & Variations

“To get the crispiest edges, make sure your skillet or griddle is very hot before smashing the patties down. Don’t overcrowd the pan to avoid steaming.”

  • Make it vegan: Use vegan cheese and swap mayo for vegan mayo or avocado spread.
  • Add more flavor: Incorporate finely chopped jalapeños or chipotle powder for a smoky kick.
  • Different beans: Try chickpeas or kidney beans instead of black beans for a flavor twist.
  • Gluten-free option: Use gluten-free buns and tamari instead of soy sauce.
  • Extra texture: Fold in chopped nuts or seeds like walnuts or sunflower seeds.
  • Make it spicy: Top with pepper jack cheese or add hot sauce to your condiments.
