Vegan Big Mac Burger

A plant-based take on the world-famous Big Mac: smoky black bean and oat patties stacked with creamy special sauce, crisp lettuce, pickles and melty cheddar on a triple-decker bun. Ready in about 50 minutes and every bit as satisfying as the original.

Ingredients 

For the patty:

  • 1 Tbsp coconut oil
  • 2 ½ cups black beans cooked
  • 1 cup onion finely chopped
  • 2 cloves garlic finely chopped
  • ½ cup carrot grated
  • 1 cup rolled oats
  • ¾ cup oat bran
  • 2 Tbsp psyllium husks or freshly ground flax seeds; a whole egg also works for a non-vegan version
  • 2 Tbsp fresh greens
  • 2 Tbsp sunflower seeds lightly roasted
  • 1 Tbsp mustard
  • 2 Tbsp ketchup
  • 1 tsp red pepper flakes
  • 1 tsp salt
  • ½ tsp cumin powder
  • 1 Tbsp lemon juice

For the sauce:

  • 4 Tbsp mayo vegan or regular
  • 1 Tbsp olive oil
  • 1 Tbsp apple cider vinegar
  • 1 Tbsp pickles finely chopped
  • 1 tsp maple syrup or honey
  • 1 tsp onion powder
  • 1 tsp sweet tomato sauce
  • 1 pinch salt and chili

To assemble:

  • 4 burger buns cut into 3 equal parts
  • 4 slices Cheddar cheese vegan or regular
  • 1 cup lettuce shredded
  • 1 Tbsp onion finely chopped
  • 1 pickled cucumber sliced

Instructions

  • Mix all the sauce ingredients in a bowl and set aside.
  • To make the patties:
  • Heat a little coconut oil in a frying pan over medium heat. When hot, add the chopped onion, garlic and carrot. Cook, stirring occasionally, until the onion is translucent and soft.
  • Add the beans to a large bowl and mash them until smooth with a potato masher or an immersion blender. Add the oats and blend a few more times; a food processor works too. Add all the remaining ingredients along with the cooked onion mixture and mix until well incorporated. Let the mixture sit for about 10 minutes, so the flavors come together and the liquid is absorbed.
  • Form 8 patties.
  • Heat a large skillet over medium heat. Add a little coconut oil and cook the patties in batches, for about 4 minutes on each side.
  • To assemble the Big Mac, lightly toast the bun slices.
  • On the first bottom bun, add ½ Tbsp sauce, 1 Tbsp shredded lettuce, ½ tsp chopped onion, a slice of cheddar, 1 patty and 2 slices of pickled cucumber.
  • Top with the next bun slice and repeat with the remaining ingredients, except the cheese. Cover with the bun top and serve with extra sauce or ketchup.

Notes

For patties that hold together, mash the beans until smooth and let the mixture rest for 10 minutes before shaping, so the oats and psyllium can absorb the liquid. The special sauce keeps in a sealed jar in the fridge for up to 5 days, and uncooked patties can be frozen between sheets of baking paper for up to 3 months.
