Instructions
- Step 1: Preheat air fryer to 400°F (200°C). Thinly slice 1 large onion (about 8 oz) into 1/4-inch rings, discarding the tough root end.
- Step 2: In a bowl, combine 3 tbsp grated parmesan, 1 tbsp finely chopped fresh dill, 1/4 tsp garlic powder, and 1/8 tsp sea salt. Add 1 tbsp olive oil and mix into a paste.
- Step 3: Toss the onion rings in the paste until fully coated. Arrange in a single layer in the air fryer basket. Air fry for 12 minutes at 400°F, shaking the basket halfway through, until the rings are deeply golden and crisp around the edges.
