Place one flour tortilla in the air fryer basket. You will need to weigh it down with a wire trivet because the hot air might flip it around and keep it from cooking evenly. If using small sized tortillas, be sure to place them in a single layer. Set the air fryer to 390 degrees F and air fry for 4 minutes, flipping halfway through.
Add about ¼ cup of the refried beans to the top of the tortilla. Gently spread the beans evenly close to the edge. Top with about ¼ cup of shredded cheese evenly as well.
Air fryer for another minute, or until the cheese is melted to your preference.
Carefully remove the tostada and add your favorite toppings.
Notes
Serve whole or cut into triangles.
Add a squeeze of fresh lime juice for added brightness.
Season refried beans with ½ teaspoon chili powder, ½ teaspoon garlic powder, and ⅛ teaspoon cumin, or a tablespoon of taco seasoning for added flavor.
Top with shredded leftover chicken for added protein.
