This will help to prevent the tortilla from flying around in the basket as it cooks.
Place one tortilla into the air fryer and place a trivet or small wire rack over the top to help hold it down.
Cook the tortilla at 390 degrees F for 3-4 minutes (depending on how dark you want it) and flip it halfway through the cooking process.
Top your tortilla with about ¼ cup of beans, ¼ cup of shredded chicken, and 3 tablespoons of cheddar cheese before air frying for an additional 1-2 minutes or until the cheese is melted.
Remove the tostada and then top with your favorite toppings like shredded lettuce, diced tomatoes, or black olives.
Repeat the cooking process for all tostadas and serve warm.
