Drain (reserve the aquafaba for the recipe) and rinse the chickpeas and pat dry.
Process the chickpeas in a food processor until the beans begin to become creamy, but still have texture. You should see solid pieces, not whole beans.
Scrape the processed chickpeas into a large mixing bowl and add the chopped onion, bell pepper, minced garlic and parsley, 1 ¼ cups breadcrumbs, 3 tablespoons of aquafaba (more if necessary),1 teaspoon of garlic powder and cumin, ⅛ teaspoon of cayenne pepper, and salt and pepper to taste. Stir until fully combined.
Divide the mixture into 4 equal sections and form into patties. You can cook immediately, although they set up better for cooking if refrigerated for at least an hour.
Heat 2 tablespoon of oil on medium heat in a large frying pan. When the oil is hot, add the patties to the pan and cook until golden brown, approximately 7 minutes, and then flip and cook the other side until golden brown.Cover with a lid to ensure that they cook all the way through.
Notes
Why not add the onion to the food processor?Onions have a lot of water, so when you process them they will release the water and make the mixture too wet. It's best to finely chop them and fold them in.
Refrigerate the patties for an hour before cooking.The burgers will set as they chill, making it less likely that they'll fall apart while cooking.
Can I bake them?Yes, you can bake them in a 375°F (190°C) oven for approximately 10-12 minutes per side, or until they're golden brown. Spray or brush with a thin film of oil to make them crispy.
How to store and freeze.To store unbaked patties, stack between parchment paper and place in an airtight container in the refrigerator for up to 3 days. Freeze in a freezer safe container for up to 2 months. Thaw in the refrigerator.
