Air Fryer Crispy Fried Onions Recipe

by

Air Fryer Fried Onions are a simple way to turn fresh onions into golden, sweet, crisp, and flavorful toppings without deep-frying them in a large amount of oil. They are incredibly versatile and can be used to add texture and savory sweetness to burgers, sandwiches, soups, salads, rice dishes, curries, casseroles, dips, and many other meals.

The air fryer makes the process convenient because hot air circulates around the thin onion slices, gradually removing moisture and encouraging them to become beautifully browned. Only a small amount of cooking oil is needed, making this a practical alternative to traditional fried onions.

The most important part of this recipe is patience. Onions contain a considerable amount of water, so they need time to soften, dry, and eventually develop their golden-brown color. Cooking them too quickly at a very high temperature can cause the outside to burn before the moisture has evaporated. Using a lower temperature toward the end helps create a more evenly cooked result.

This recipe makes approximately 1 pound of crispy air-fried onions and requires only a few basic ingredients.
