Air Fryer Gluten Free Onion Ring - Crispy, Light, and Easy

Prep Time10 minutes
Cook Time12 minutes
Total Time22 minutes
Servings: 4 servings

Ingredients

  • 2 large sweet onions (Vidalia or Walla Walla work well; yellow onions also fine)
  • Gluten free all-purpose flour blend (1 cup; ideally one with xanthan gum)
  • Cornstarch (2 tablespoons, for extra crispness)
  • Gluten free panko-style breadcrumbs (2 cups)
  • Eggs (2 large)
  • Milk or unsweetened dairy-free milk (1/2 cup)
  • Smoked or sweet paprika (1 teaspoon)
  • Garlic powder (1 teaspoon)
  • Onion powder (1/2 teaspoon)
  • Cayenne pepper (optional, 1/4 teaspoon)
  • Kosher salt and black pepper
  • Oil spray (avocado or olive oil spray for air fryers)
  • Optional dips: ketchup, ranch, honey mustard, or a simple sriracha-mayo

Instructions

  • Prep the onions: Peel onions and slice into 1/2-inch thick rings. Gently separate the rings. Pat dry with paper towels so the coating sticks.
  • Set up three bowls: In bowl one, whisk together gluten free flour, cornstarch, paprika, garlic powder, onion powder, 1 teaspoon salt, and 1/2 teaspoon pepper. In bowl two, whisk eggs with milk. In bowl three, add gluten free panko with a pinch of salt and pepper.
  • Preheat the air fryer: Set to 385°F (195°C) for 4 minutes. A hot basket helps the coating crisp immediately.
  • Coat the rings: Working a few at a time, dip rings in seasoned flour (shake off excess), then egg mixture (let drip), then press into panko until well coated. Place on a tray as you go.
  • Spray lightly with oil: Mist both sides of the coated rings with oil spray. This is key for even browning in the air fryer.
  • Air fry the first batch: Arrange rings in a single layer in the air fryer basket without overlapping. Cook 8–10 minutes, flipping halfway and spraying the second side. They’re done when golden and crisp.
  • Repeat: Continue with remaining rings. Keep cooked ones on a wire rack so the bottoms stay crisp.
  • Taste and season: Sprinkle with a little extra salt right after cooking, if needed. Serve hot with your favorite dips.
