5. To bake: Arrange the tacos in a single layer on two large baking sheets. Spray with non-stick cooking spray (optional) and bake for 10-12 minutes, flipping the tacos halfway through so that they are crispy on both sides. Remove from the oven and serve warm with your choice of dipping sauce(s). To air-fry: Preheat your air fryer at 400 degrees for five minutes. If desired, line your air fryer basket with parchment paper. Then, in batches, cook the mini tacos in a single layer at 400 degrees for six minutes, flipping them halfway. *Be careful not to overcrowd the basket. Serve warm with your choice of dipping sauce(s).
