There's something undeniably delightful about a perfect batch of onion rings, and when prepared in an air fryer, they reach a new level of crispiness without the excess oil. To make the best air fryer onion rings, begin by slicing large onions into thick rings, ensuring they maintain their structure during cooking.

Next, coat the onion rings in a light dusting of flour, followed by a dip in beaten egg, and finish with a generous coverage of seasoned breadcrumbs. The air fryer works its magic by circulating hot air around the rings, achieving that golden-brown exterior while keeping the insides wonderfully tender.

Serve them with a tangy dip or a side of homemade aioli, and you've got a scrumptious snack or side dish that's healthier than traditional frying, yet just as satisfying. Perfect for a cosy night in or as a party starter, air fryer onion rings are a real triumph in the kitchen!
