Frozen Tostones: Start with frozen tostones, which are essentially green plantain slices that have been partially cooked and flattened. They are widely available in the frozen section of grocery stores.

Preheat Air Fryer: Preheat your air fryer to 400°F (200°C) for a few minutes. This will ensure that the air fryer is hot and ready to cook the tostones.

Arrange Tostones: Take the frozen tostones out of the freezer and arrange them in a single layer in the air fryer basket. There's no need to thaw them beforehand.

Cooking Spray or Oil: If you want extra crispiness, you can lightly spray the tostones with cooking spray or brush them with a small amount of oil. This will help them get golden and crispy in the air fryer.

Air Fry Tostones: Place the basket with the tostones into the preheated air fryer. Air fry the tostones at 400°F (200°C) for about 12-15 minutes, flipping them halfway through the cooking time. Cooking times may vary based on the size and thickness of the tostones and the air fryer model, so keep an eye on them to avoid overcooking.

Check Doneness: The tostones should be golden brown and crispy on the outside when they are done.

Optional Salt: If desired, sprinkle some salt over the tostones while they are still warm to enhance their flavor. The salt can bring out the natural sweetness of the plantains.

Serve and Enjoy: Once the tostones are cooked to your desired crispiness, remove them from the air fryer and let them cool for a minute or two before serving. Enjoy your delicious and crispy air-fried tostones as a delightful snack or side dish!
