Ingredients
You’ll need just a few simple items to make this crunchy perfection:
- 2 large yellow onions, thinly sliced into rings
- 1 cup buttermilk (or milk with 1 tsp vinegar as a substitute)
- 1 cup all-purpose flour
- ½ cup panko breadcrumbs
- 1 tsp garlic powder
- 1 tsp paprika
- ½ tsp onion powder
- ½ tsp salt
- ¼ tsp black pepper
- Olive oil spray (or avocado oil spray)
Instructions
- Prep the Onions:
Slice your onions into even rings, about ⅛ inch thick. Separate the rings gently and place them in a bowl. - Soak in Buttermilk:
Pour the buttermilk over the onions and let them soak for at least 10 minutes. This softens the onion bite and helps the coating stick better. - Mix the Coating:
In another bowl, combine flour, panko, garlic powder, paprika, onion powder, salt, and pepper. Stir well to distribute the seasoning evenly. - Coat the Onion Rings:
Remove onions from buttermilk, shaking off excess. Toss each handful into the flour mixture until well-coated. For an extra crunchy finish, repeat this step once more (dip back in buttermilk and flour again). - Preheat the Air Fryer:
Set your air fryer to 375°F (190°C) and let it preheat for 3 minutes. - Arrange and Spray:
Place coated onions in the air fryer basket in a single layer (avoid overcrowding). Lightly spray with olive oil to help crisp them up. - Air Fry Until Crispy:
Cook for 7–9 minutes, shaking the basket halfway through. They should be golden brown and irresistibly crisp. - Cool and Serve:
Transfer to a wire rack to cool — they’ll crisp even more as they rest. Serve immediately or store for later use.

Notes
Tips for the Perfect Crunch
- Slice evenly: Thinner slices cook more evenly and crisp up better.
- Don’t overcrowd the basket: Air circulation is key for maximum crunch. Cook in batches if needed.
- Use panko breadcrumbs: They create a lighter, flakier crust compared to regular breadcrumbs.
- Light oil mist: A fine spray helps achieve that deep-fried texture without greasiness.
- Shake halfway: Keeps the coating crisp on all sides.
Variations
- Spicy Kick: Add cayenne pepper or chili flakes to the coating for a fiery touch.
- Gluten-Free Option: Substitute flour with chickpea or rice flour and use gluten-free breadcrumbs.
- Keto-Friendly Version: Replace flour with almond flour and skip the breadcrumbs entirely.
- Sweet & Savory: Mix in a pinch of brown sugar with paprika for a Southern-style twist.
- Cheesy Upgrade: Add a tablespoon of grated Parmesan before air frying.

To Reheat:
Re-crisp in the air fryer at 350°F for 2–3 minutes before serving. Avoid microwaving — it will make them soggy.
