1. Start by slicing onions for onion rings. Aim for slices about 1/2 inch thick for the perfect balance of softness and crunch.

2. Once sliced, separate the rings carefully to avoid breaking. This is crucial for preparing onions effectively.

3. For the coating, explore gluten-free coating options like coconut flour or low-carb onion ring coating choices such as almond flour. These are excellent breadcrumb substitutes.

4. Prepare your chosen coating by mixing it with spices in a shallow dish for easy dipping.

5. Dip each onion ring in a mixture of beaten eggs first. This step is key for the coating onion rings without breadcrumb to stick properly.

6. After the egg wash, coat each ring thoroughly in your flour mixture. It’s important to press the coating gently onto the onion to ensure a crispy texture.

7. Preheat your air fryer to 375°F. This air fryer setting for onion rings helps in achieving the perfect crispiness.

8. Arrange the coated onion rings in a single layer in the air fryer basket. Avoid overcrowding for even cooking.

9. Cook for about 5 minutes, then flip the rings and cook for another 3 minutes. Watch closely to prevent burning and to achieve crispiness.

10. Once done, let them cool for a minute or two before serving. They’re best enjoyed fresh!
