To air-fry the quinoa bean burger patties, set the air fryer to 375 degrees and air fry the burger patties for 15 minutes. Spray the burger patties with cooking spray or oil before placing them in the air fryer basked and make sure you don't crowd the basket -- leave a little room between the patties. To bake the burgers, place them on an oiled or parchment lined baking sheet with at least an inch between the patties. Bake in a preheated 375 degree oven for 20-25 minutes, flipping once halfway through.
