What Kind Of Onions To Use?

How to Air Fry Onions

Step 1

Clean the onion by cutting off the two ends and removing the peel.

Cut it in half and then into slices with a sharp knife.

I recommend wetting the knife blade with cold water because it reduces the typical risk of weeping from cutting the onion.

The operation can be done several times and not only before starting to cut.

Step 2

In a shallow bowl put the onions, and season with oil, salt and pepper and mix well so that all the onions are covered by the oil.

Meanwhile, preheat the air fryer.

Step 3

Transfer the onions to the air fryer basket, don’t worry if they overlap, don’t need to put in a single layer as the onion will shrink while cooking, cook for 10 to 12 minutes, stirring occasionally during the cooking process

Leftovers

Store: You can store air fryer onions up to 4 days after cooking. Let them cool, cover, and refrigerate in an airtight container.

Reheat: You can reheat onions in microwave for 30 seconds.
