Method
Soak the chickpeas for 8 hours or overnight.
Preheat the oven to 400°F.
Drain the chickpeas and add to a food processor along with the chili, onion, garlic, lemon juice, and spices. Process well, but not so much that it makes a dough. It should have a sand-like texture. Add the chickpea flour and mix well.
Form balls or patties and place on a parchment-lined baking sheet and bake for 10-15 minutes. If you have an air fryer, you can air fry the falafels for a few minutes just to get that perfect browned outer texture.
