Here I am sharing with you how to prepare crispy fried onions in an air fryer. A perfect healthy alternative to deep-fried onions that you can use in your favorite dish without the guilt.
Let’s get started!
What you will need?
- Onion – I use thinly sliced onion for making these fried onions
- Cooking oil – some cooking oil to coat the onion lightly
How to cut onion for making crispy onions in Air Fryer?
Peel a large onion, trim one end and leave the other end to hold. Then using a mandolin, slice the onion on its largest setting (it’s 3mm in my slicer). Mandolin helps cut the onion into even round slices, which helps in even cooking in the air fryer. Gently separate the rings before adding them to the air fryer.
You can also use a sharp knife to slice the onion. Make sure to cut the slices as even as possible.
How to prepare Air Fryer crispy onions?
Preheat the air fryer to 300F (if the preheat option is available in your AF). Coat the onion rings with some oil and place them in the air fryer basket. Initially fry the onion at 300F for 10 min, then reduce the temperature to 240F and continue frying them until crispy and well done. Keep stirring the onion every 5 min of cooking. For even heating, texture, and color it is necessary to shake the onion at regular intervals.
How to use fried onions?
There are many ways you can use these crispy golden strings of onion. Here are some ways to think of using them…
- Add these crispy onions into salads, soups or top it onto homemade pizza or veggie flatbread for added flavors.
- Use them in making your favorite Indian chicken biryani or vegetable biryani. It is one of the most important ingredients in biryani dishes.
- You can even use it for making curries like chicken tikka masala, lentil curry, palak paneer, etc. Just use fried onion and skip the step of sautéing the onion in the recipe. It will save some time if you have pre-made fried onion.
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.
FAQs:

Thank you for sharing this recipe. I can now make my favourite Austrian dish Wiener Zwiebelrostbraten (fried beef and onions in gravy) and need to be topped with crispy fried onions. This will be so much easier and healthier.
I made these in a convection oven on a roasting rack It’s really good!
Love this recipe as it’s not only less oily but perfectly safe for those of us Celiac’s.
Store brands contain wheat and the GF brands taste terrible. I can control the ingredients and crispness and know I’m safe in eating them. Thank you.
Interesting temps and times instead of “full power”.🤪 I used them for revisions to the old green bean casserole (which I do not like). I steamed fresh green beans to almost done, then sauteed the trio (onions, celery, butter), tossed in the usual mushroom soup, but sparingly into a baking dish. Fixed the onions as above, but stopped before max crispy since I placed them, along with a few Panko crumbs on top of mixture to go into a 375°F oven until nice and bubbly, and further browned onions (ca. 20 min for our small dish for 4). The combo of these lovely, non-greasy onions and fresh green beans (courtesy of Costco) turned an old dish I never really liked into something fresh and delicious. Maybe it was not as crunchy as the first bite of the old canned onion rings, but this time no greasy aftertaste. Thank you for the creative timing involved in the recipe. Very clever!🤗
Also, thanks to all for other suggested uses. They are on my list.
Perfect! I’ve avoided them because of the fat but I just got an air fryer. I love love love onions like this. I put them on a burger. I use them on green beans with dried cranberries and crispy prosciutto. They’re good on tuna sandwiches, nachos, cod, rice and mashed potatoes. THANKS!
Thanks for sharing this air fried onion recipe. I used it for making chicken biryani. This is much better than store-bought ones that are very oily.
