Air fryer roasted onions are a simple, quick, and delicious recipe, perfect as both an appetizer and a light side dish. With just a few minutes of cooking, you’ll achieve a result very similar to classic baked onions, but with the convenience of an air fryer: golden on the outside, soft and tasty inside, in about 10 minutes.
To prepare onions in the air fryer, you can choose between white, golden, or the more delicate flat onions: just cut them in half or into thick slices, season them with a drizzle of olive oil, a pinch of salt, and oregano. A little trick? Add a splash of vinegar directly during cooking: it will make the onions more digestible and give them an irresistible scent.

Air fryer roasted onions will win you over with their simplicity… and once you’ve tried them, you won’t let them go.

How to Cook Onions in the Air Fryer
To prepare air fryer roasted onions, start by peeling the onions. If using round onions (golden, white, or red), cut them into slices about 1/2 inch thick (1). If using flat onions, cut them in half. Line the basket of the air fryer with appropriate paper, then place onion slices next to each other (2). Season with about a tablespoon of oil and a tablespoon of vinegar; to distribute them best, you can use an oil sprayer (3) or a kitchen brush.
Add a pinch of salt, a grind of pepper, and a pinch of dried oregano (4). Cook the onions in the air fryer at 338°F for 10 minutes. Check the cooking level and, if needed, continue for another 2 minutes. When they are soft and golden, remove the basket (5) and let them cool.
Serve the roasted onions cold, as a tasty appetizer or as a side for meat main courses.
Storage
You can store the onions in the fridge, in a glass container, for about 3 days.
Tips and Variants
You can also flavor the onions with chives or parsley, to be added at the end of cooking.
