Ingredients

For the Patties:

  • 2 vegan burger patties around 200 grams, 7 oz
  • cooking oil for frying
  • 2 teaspoons miso paste optional
  • 2 teaspoons water optional, for the miso glaze

For the Veggies:

  • 2 burger buns sliced
  • 2 slices lettuce
  • 6 Tablespoons vegan burger sauce
  • 12 slices pickles
  • 1 large tomato sliced
  • ¼ cup caramelized onions & mushrooms or substitute with 1/2 red onion, sliced

Instructions

  • Form the Patties: Divide each vegan burger into 2 equal portions. Roll each part into a ball, so you should get 4 vegan meatballs.
    2 vegan burger patties
  • Smash the Patties: Place each ball between two pieces of parchment paper. Use a pan lid to press down firmly, forming a thin patty. Be careful not to press them too thin so the patty won't break apart.
  • Cook the Patties: Heat your cooking oil in a pan/(cast iron) skillet over medium heat. Pan-fry the smashed burger patties for about 3 minutes on each side until they are crispy and browned.
    Press them down with your spatula from time to time to ensure even browning.

  • Add the Miso Glaze: In a small bowl, mix 2 teaspoons of miso paste with 2 teaspoons of hot water. About 1 minute before the second side of the patties is done, spoon the miso mixture on top and let the vegan meat absorb the flavor.
    Turn off the heat after about 1 minute. Note that you don't need to flip the patties again to 'cook' the miso glaze.
    2 teaspoons miso paste, 2 teaspoons water
  • Toast the Buns: Slice each burger bun in half. In the same pan, toast the cut sides with a little bit of oil for 1-2 minutes until golden brown.
    2 burger buns
  • Assemble the Burgers: Add lettuce to the bottom side of the bun, then spread your vegan burger sauce on the lettuce. Top with the first smashed patty, slather with more vegan burger sauce, followed by the second patty. Then add the pickles, tomato, and caramelized onions & mushrooms (or red onion). Close with the top bun, and enjoy!
