Instructions

• Preheat the oven to 200°F to keep finished batches warm. Trim and peel the onions, slice into thick rings, and separate the rings.
• Set up three shallow bowls: flour in the first; eggs beaten with milk in the second; and panko in the third. Mix the smoked paprika, onion powder, garlic powder, and salt separately, then divide the seasoning evenly among the three bowls and stir each to combine.
• Coat each onion ring first in flour, then in the egg mixture, then in the panko mixture, pressing the crumbs onto the ring.
• Generously spray the air-fryer basket with cooking spray. Arrange a single layer of onion rings and spray the tops. Air fry at 375°F for 10 minutes, flipping halfway through.
• Transfer the cooked batch to a baking sheet in the warm oven while cooking the remaining rings. Serve with dipping sauce if desired.
