Step 1: Prepare the Onions
- Slice the Onions:
- Peel the onions and slice them into 1/2-inch thick rings. Gently separate the rings from each other.
- Soak in Buttermilk:
- Place the onion rings in a bowl and cover with buttermilk. Let them soak for at least 30 minutes to ensure they are flavorful and tender.
Step 2: Prepare the Breading Station
- Set Up Breading Stations:
- In one shallow dish, combine the flour, paprika, garlic powder, onion powder, cayenne pepper (if using), salt, and black pepper.
- In a second shallow dish, beat the egg.
- In a third shallow dish, mix the panko breadcrumbs with the grated Parmesan cheese (if using).
Step 3: Bread the Onion Rings
- Coat Onion Rings:
- Remove the onion rings from the buttermilk and let any excess drip off.
- Dredge each onion ring in the seasoned flour mixture, ensuring it is fully coated.
- Dip the floured onion ring into the beaten egg, allowing any excess to drip off.
- Coat the onion ring in the panko breadcrumb mixture, pressing lightly to adhere.
Step 4: Air Fry the Onion Rings
- Preheat Air Fryer:
- Preheat your air fryer to 400°F (200°C) for about 3-5 minutes.
- Arrange Onion Rings:
- Place the breaded onion rings in the air fryer basket in a single layer. Do not overcrowd the basket; you may need to work in batches.
- Spray with Cooking Spray:
- Lightly spray the onion rings with cooking spray to help them crisp up during cooking.
- Air Fry:
- Air fry the onion rings at 400°F (200°C) for 8-10 minutes, or until they are golden brown and crispy. Shake the basket or flip the rings halfway through for even cooking.
- Cool and Serve:
- Allow the onion rings to cool slightly before serving. This helps them maintain their crispiness.
Step 5: Serve
- Dip and Enjoy:
- Serve the onion rings with your favorite dipping sauces, such as ketchup, ranch dressing, or a spicy aioli.
Tips for Perfect Air Fryer Onion Rings
- Even Coating: Ensure the onion rings are evenly coated in the flour, egg, and breadcrumb mixtures for the best texture and flavor.
- Crispiness: For extra crispiness, consider using a combination of panko breadcrumbs and grated Parmesan cheese.
- Batch Cooking: Cook the onion rings in batches to avoid overcrowding, which can prevent them from getting crispy.
