Crispy Air-Fried Onion

Crispy Air-Fried Onion

Crispy Fried Onions: Using an air fryer with a small amount of oil, prepare crispy fried onions. To get the crispy, caramelized texture and tastes, deep-frying is not necessary.

How Should Crispy Fried Onions Be Stored? Before storing, let the onion strings to cool fully. After that, put them in refrigerator-safe container that is airtight.

For What Length of Time Should Store? These fried onions keep well in the refrigerator for up to week when kept in an airtight container.


  • Air Fryer;
  • Mandolin Slicer;


  1. 1 tablespoon frying oil;
  2. 2 medium-to-large yellow onions (about 1 pound).


  • Slice the onion thinly round after peeling.
  • After drizzling the slices with oil, carefully separate the rings.
  • Put the onion rings inside the basket of the air fryer. Initially, fry them for 10 minutes at 300°F. Mix the rings gently every five minutes.
  • Reduce the temperature to 240 degrees Fahrenheit and proceed with cooking the rings. Gently stir the rings every five minutes. At 240F, it will take 15–18 minutes to achieve the right texture and color.


  • Red or yellow onions may be used. But take note that the red onion will make the fried onion deeper in color.
  • Depending on how many onions are in the air fryer, different cooking times may apply. This time is for about one pound of onions. Should your batch be a little bigger, just continue to fry, inspecting after every five minutes at 240 degrees Fahrenheit, until the color and texture are to your liking.

Helpful Tips!

  • If you are using a red onion, you may get dark brown fried onions in the end. Yellow onions result in a golden brown color after frying.
  • Cut onion slices as even as possible. Or else you may get uneven color and texture after frying them. A mandolin slicer is a perfect tool for getting even slices. This will also speed up the cutting process.
  • Drizzle the oil before separating the onion rings from the slices. It will help to distribute the oil evenly.
