1. Soak the sliced onions in buttermilk for at least 30 minutes. This not only adds flavor but also helps them to become extra crispy.
2. In a separate bowl, combine the flour, garlic powder, paprika, salt, and pepper. Mix well to combine all the dry ingredients.
3. Remove the onions from the buttermilk and let any excess liquid drip off. Dredge the onions in the flour mixture, ensuring they are fully coated.
4. Preheat your air fryer to 375°F (190°C) for about 3-5 minutes.
5. Spray the air fryer basket with cooking spray. Place the coated onions in the basket in a single layer, making sure not to overcrowd them.
6. Lightly spray the tops of the onions with more cooking spray for that golden finish.
7. Air fry for 10-15 minutes, shaking the basket halfway through, until the onions are golden brown and crispy. Keep an eye on them towards the end to avoid burning!
8. Once done, let them cool slightly before serving. They’ll crisp up even more as they cool!
