The Best Vegan Burger Recipe Hack? Use a Flax Egg

This vegan burger brings the heat and flavor, from green chilis to harissa paste.

Some days, it can feel hard to get excited about a veggie burger. We have them in our freezers, and plop them on the grill when we can’t be bothered to do more than flip a patty. But it’s worth making your own burger at home, because you can up the umami by adding the right ingredients.

Our best vegan burger recipe employs several genius hacks, including a flax egg to bind the patty and just a dash of cayenne to spice it up. Black beans and green lentils boost the protein quotient, while flavor multiplies exponentially when you add mushrooms, red onion, green chilis, tomato puree, and soy sauce.

Before you dive in, banish boring burgers forever by mixing up a standard sauce with a less typical topper. Harissa paste and mayonnaise are a match made in burger heaven.

  • gherkins
  • 4 tablespoons vegan mayonnaise
  • 1 teaspoon harissa paste (optional)

Preparation

  1. 1
    Begin by heating a pan on a medium heat and adding the oil and diced mushrooms. Cook for 5 minutes stirring frequently, then put to one side to cool.
  2. 2
    Next, mash the black beans in a large bowl and add the diced red onion, flax egg, green lentils, crushed garlic, tomato puree, soy sauce, paprika, dried oregano, cayenne pepper, gram flour and diced green chilli. Add the cooled mushrooms and combine.
  3. 3
    Form into 4 large patties and place onto a lined baking tray. Cover them and place in the fridge for a minimum of 2 hours or ideally overnight.
  4. 4
    When ready to cook heat a large pan on a medium heat and add the vegetable oil.
  5. 5
