Prepare the Flour Mixture: In a mixing bowl, combine 1 cup of all-purpose flour, 2 teaspoons of garlic powder, ½ teaspoon of ground black pepper, and 2 teaspoons of sea salt. Whisk these ingredients together until they are well blended.
Preheat the Air Fryer: Set your air fryer to preheat at 350° F. This is an important step that helps ensure even cooking and browning of the peppers.
Coat the Peppers: Take your sliced banana peppers (ensuring you have removed the seeds) and dip them into the flour mixture. For a thicker coating, allow them to sit for 5 minutes after coating.
Arrange in the Air Fryer: Place the coated banana peppers in a single layer in the air fryer basket. Avoid overcrowding to allow for proper air circulation.
Spray with Olive Oil: Lightly spray the peppers with olive oil. This step is key to obtaining that crispy texture.
Air Fry: Cook the banana peppers in the air fryer for about 8 minutes, or until they are golden brown and crispy. Keep an eye on them towards the end to prevent burning.
Drain Excess Oil: Once cooked, transfer the banana peppers to a paper towel-lined baking sheet. Let them drain for a few moments to remove excess oil, allowing them to cool for 5 minutes.
Serve: These crispy treats can be served warm with a side of ranch dressing for dipping. Enjoy your delicious Air Fryer Banana Peppers as a snack or topping for other dishes!
