Ingredients

  • 1 large yellow or white onion
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon garlic powder
  • 2 teaspoons smoked paprika
  • 1 teaspoon salt
  • 1/2 teaspoon cayenne pepper
  • 1/2 teaspoon black pepper
  • 2 cups buttermilk
  • Cooking spray

Instructions

  • Peel the onion and slice them thinly into rings. I recommend a mandolin slicer for this, to get even, very thin rings.

  • Place the onion rings into a medium sized bowl. Then pour the buttermilk over the onion and coat evenly. Allow the onions to soak for 15 minutes.

  • While the onions are soaking, preheat your air fryer to 375°F (190°C) for about 5 minutes. In a second medium sized bowl, combine the flour, garlic powder, smoked paprika, salt, cayenne pepper and black pepper.

  • Air fry at 375°F (190°C) for 8-10 minutes, flipping halfway through, or until they are golden brown and crispy. Depending on the size of your air fryer, you may need to work in batches.

  • Once the onion strings are cooked to your desired crispiness, transfer them to a serving plate and season with a sprinkle of coarse salt. Serve hot with your favorite dipping sauce, such as sriracha mayo, ranch dressing, or barbecue sauce.
