How To Reheat Onion Rings in an Air Fryer? (3 popular methods exposed)

FACT: Onion rings are yummy, and most of us enjoy eating them. When we have some leftovers, the problem comes in, and we don’t know what to do with them when we have leftovers.


How To Reheat Onion Rings in an Air Fryer?

Preheat your air fryer to 350 degrees then place the onion rings inside and cook for 2-3 minutes until warmed. Reheating them at a lower temperature allows the insides to reheat while making sure the outside doesn’t get too crispy or burnt.


After doing the research, I uncovered more information you need to be aware of so please keep on reading…



2 Best Methods For Reheating Onion Rings | And One Method To Stay Away From

1. Stove Method


Another way to reheat the rings is on top of your stove. It’s fast and easy, and if you follow the steps I’ve laid out below, you should end up with a lovely, crispy, mouthful of joy…


  • Put some oil in a frying pan and heat on your stovetop. The larger the portion, the more oil you will need. Place the frying pan onto the stovetop and heat the oil.

  • Carefully lower the rings into the oil and cook until warmed through and crispy on the outside.

  • Serve and enjoy.


2. Stay away from the microwave


There is no surer way of ruining potentially delicious leftover onion rings than by heating them in a microwave. When it comes to fried foods and the microwave, ne’er the twain should meet.


If you do try, take it from me, you will end up with a warm, soggy, disaster (I learned the hard way). You would be far better off eating them cold. As far as fried foods are concerned, the microwave is their absolute nemesis (you have been warned).

3. The oven/toaster method


How can you eat your burger and fries without onion rings? With deep regret, that’s how. But you shouldn’t have to. Let me tell you how to magic up the best, crispy reheated leftover onion rings ever, to make your meal complete. Reheat them in your conventional oven or toaster oven…


  • Preheat your oven/toaster to 350°F

  • Then, nuke the onion rings in the microwave for 10 seconds burst just to make the middle gets warm.

  • Stick them in the toaster/oven. Keep the rings elevated on a rack so the bottom doesn’t get soggy. Put some foil under the rack (not under the food) to catch the grease (optional).

  • Cook for around 5 to 6 minutes (or until hot and crispy)

  • Serve and eat straight away.

How Long Do Onion Rings Keep In The Fridge?

FYI: Cooked onion rings will last three to five days in the refrigerator…


This time frame only applies to onion rings that were stored in an air-tight container and placed in the fridge two hours after the onion rings finished cooking. Suppose the onion rings sat out for three or four hours on the kitchen counter. Throw those onions out.


They sat out too long to be considered safe for human consumption. Because bacteria will multiply in the onions when they are left uncovered for more than two hours in temperatures ranging between 40 °F and 140 °F.



Can You Freeze Cooked Onion Rings?

FACT: According to the National Center for Food Preservation, freezing onion rings is a safe method to preserve your onion rings for later usage.


Moreover, there are food safety precautions to follow to ensure that your frozen onion rings will be safe for consumption…


  • To begin, peel, wash and chop the onions into slices.

  • Next, blanch the raw onion rings for 10 to 15 seconds in boiling water.

  • Next, remove the onions from the boiling water with a slotted spoon and place those in a colander to cool and drain.

  • Please be sure to check that the onions are completely cool before moving to the next step. Then, dip the raw onions into cold milk, and coat the rings with a breading of your choice.

  • Now, place the breaded onion rings single file onto a clean baking sheet or tray. Freeze the onion rings separated on the sheet to avoid the onion rings freezing in clumps.

  • Once the rings are fully frozen, pack those into a Ziploc container or bag with saran wrap protecting the layers of onion rings from sticking to each other and seal the bag.


Please note that the onion rings will keep in the freezer for ten months to one year. It is not advisable to consume any onion rings past one year of storage in the freezer.



What To Do With Leftover Onion Rings?

Several recipes will use up those leftover onion rings sitting in your refrigerator. One popular method is to fry an egg inside an onion ring for a quick and easy breakfast, brunch, or snack.


The crunchy breading and saltiness from the onion ring pairs well with the eggs’ consistency and light flavors. Another option that will put your leftover onion rings to good use is adding those rings to salads as toppings.


Chop the reheated onion rings into small pieces and sprinkle them on top of a homemade chef salad. For the best results, choose a salad dressing like honey mustard or a light vinaigrette that will pair well with the onion rings seasonings.


Suppose you enjoy comfort foods, consider replacing the french fries called for in a traditional Poutine recipe with leftover onion rings for a new version of a well-loved staple.


Allow your onion rings to warm up on the counter to room temperature. Then add those onion rings to the Poutine’s bacon, cheese, and broil the dish until the cheese melts completely.


Tips And Suggestions For Maintaining That Crispy Goodness!

  • Always remove the onion rings from to-go containers and place them into air-tight containers

  • If you have a large number of onion rings, reheat in batches to reduce crowding on baking sheets

  • Only use a slotted spoon or metal tongs to remove foods from the hot oils

  • Use paper towels to absorb excess grease when removing foods from the fryer

  • Always wear oven mitts when operating the stove or other appliances

  • Use olive oil for enhanced flavor

  • Take an air-tight container with you when you go to restaurants to store your leftover onion rings
