These double-battered air fryer onion rings deliver an irresistible crunch with less oil, making them a perfect quick and easy snack for any occasion.

Ingredients

Scale
  • Large onions (preferably sweet varieties like Vidalia or Walla Walla; firm, medium-sized)
  • 1 cup all-purpose flour
  • 1/4 cup cornstarch
  • 1 tsp baking powder
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp smoked paprika or cayenne pepper (optional)
  • 2 large eggs, room temperature
  • 1 cup buttermilk (or whole milk with a splash of lemon juice as substitute)
  • Panko breadcrumbs (Japanese style)
  • Cooking spray or light drizzle of olive oil

Instructions

  1. Peel and slice onions into 1/4-inch thick rings. Separate rings carefully and set aside.
  2. In a medium bowl, whisk together flour, cornstarch, baking powder, salt, black pepper, and smoked paprika or cayenne if using.
  3. In another bowl, beat eggs with buttermilk until smooth.
  4. Dredge each onion ring in the dry flour mixture, shaking off excess.
  5. Dip the ring into the wet batter, coating fully.
  6. Dip the ring back into the dry flour mixture, pressing gently to help coating stick (double-battering).
  7. Press each ring into panko breadcrumbs until fully coated. Lay rings on a tray.
  8. Preheat air fryer to 400°F and warm for 3-5 minutes.
  9. Arrange onion rings in a single layer in the air fryer basket without overcrowding. Spray lightly with cooking oil.
  10. Air fry for 8 minutes, flip rings, spray again with oil, and cook for another 5-7 minutes until golden brown and crispy.
  11. Transfer cooked rings to a cooling rack or paper towel-lined plate to drain excess oil. Serve warm with your favorite dipping sauce.

Notes

Use medium-sized sweet onions for best flavor. Double-battering is essential for maximum crunch. Avoid overcrowding the air fryer basket to prevent sogginess. Spray or brush lightly with oil before air frying. Reheat leftovers in the air fryer at 350°F for 3-4 minutes to restore crispiness. For gluten-free, substitute all-purpose flour with almond or rice flour and use gluten-free panko breadcrumbs. Vegan adaptations include plant-based milk, flax egg or aquafaba, and vegan panko.
