Cooking and Reheating Onion Rings in an Air Fryer in 4 Steps

Onion rings are a delicious snack or side dish, but reheating them can be tricky.

If you’re using an air fryer, however, it is easy to get the perfect crunch every time.

Here’s a simple guide on cooking and reheating onion rings in an air fryer.


How To Reheat Onion Rings in an Air Fryer?

Step 1: Preheat Your Air Fryer.

Most air fryers will have a preheat setting; if not, heat it up to 375 degrees Fahrenheit for three minutes.

This ensures that the reheated onion rings are cooked evenly and quickly in the fryer. 

Step 2: Place Your Onion Rings in the Basket of Your Air Fryer.

Make sure they are not overlapping each other; this will ensure they get maximum exposure to the hot air circulating within the chamber and cook evenly. 

Step 3: Set the Timer For Three minutes

Allow your onion rings to cook in the air fryer.

Depending on how many onion rings you have put in, you may need to adjust this time accordingly.

Keep an eye on them as they cook so that they don’t become too crispy or burnt. 

Step 4: Once finished cooking

Take out your reheated onion rings and enjoy!

You can season them with any of your favorite spices or condiments before eating if desired.

Why My Reheated Onion Rings in Air Fryer Not Crispy?

Let’s discuss why your onion rings might not have been crispy and how to change that. 

Reason #1: Too Much Moisture 

One of the most common reasons why your air fryer isn’t producing super-crispy onion rings is because there’s too much moisture in the food.

This can happen if the onion rings were stored in the refrigerator overnight. The condensation from being in an enclosed container can add moisture to the food, which makes it soggy when cooked.

To prevent this, be sure to store the onion rings in an open container or wrap them loosely with a paper towel before putting them into the air fryer. 

Reason #2: Not Enough Heat 

Another possible reason why your onion rings aren’t getting crispy is that there isn’t enough heat reaching them.

If you’re using a smaller-sized air fryer, there may not be enough hot air circulating around the food for it to get crispy on all sides.

To fix this issue, try turning up the temperature setting on your air fryer by 10-20 degrees and adding an extra minute or two to its cooking time.

This should help ensure that every side of your food gets nice and hot so it will crisp up properly. 

Reason #3: Wrong Basket Size 

The size of your basket also plays a role in getting crispy results out of your air fryer.

If you’re using an overly large basket for small amounts of food (like onion rings), then there won’t be enough contact between the food and hot air circulating inside the machine.

As a result, some parts might not get hot enough to achieve that golden-brown color and crunchy texture we all love about fried foods.

The best way around this issue is to use a smaller basket whenever possible so that more heat can reach each piece of food evenly. 

Can Raw Onions Be Air Fried?

Yes! It’s true -raw onions can actually be air fried, resulting in a flavorful and crispy morsel.

All it takes is a small amount of oil added to the onion before it is put into the fryer for about 5 minutes at 350 degrees.

The end result will be nicely browned and flavorful pieces of onion ready to top off your meal.

So if you’re looking to add texture and flavor to your dish without adding extra fats or calories from battering or deep frying, air frying may be your perfect choice.

Should You Flip Onion Rings When Reheating Them in the Air Fryer?

Yes, it is best to flip onion rings when reheating them in the air fryer. This will help ensure that both sides of the onion ring get heated evenly, resulting in a crispy texture on all sides.

If you don’t flip them, then you may end up with one side that’s soggy while the other ends up over-cooked.

So make sure to always flip your onion rings when reheating them in the air fryer for optimal results!

Benefits of Reheating Onion Rings in an Air Fryer

Here’s why you should give it a try. 

1. Convenience 

Reheating onion rings in an air fryer requires minimal effort—all you have to do is place the frozen onion rings in the air fryer basket and let the machine do the rest.

It takes less than 10 minutes to cook them up perfectly.

This is great for busy people who don’t have time to stand over a hot stove or wait for an oven timer to go off. 

2. Health Benefits 

Air frying also has numerous health benefits over other cooking methods.

Air frying uses little-to-no oil, so your food won’t be as greasy as it would be if you were deep-frying or pan-frying your food. This means fewer calories and fat without sacrificing any flavor or texture.

Plus, since air fryers cook food quickly and at even temperatures, there’s less of a risk of burning your food than there would be with other cooking methods.  

3. Flavor 

Using an air fryer helps preserve the flavor of your onion rings better than traditional cooking methods because it doesn’t require submerging them in oil or batter before cooking them.

The result is crispy onion rings that taste like they were just made from scratch!

You can also experiment with different seasonings and spices to make your onion rings unique and flavorful each time they’re reheated in the air fryer. 


For those who are looking for convenience, health benefits, and great flavor all in one package, reheating onion rings in an air fryer is definitely worth considering!

Not only does it provide quick and easy results without having to stand over a hot stove or wait for an oven timer, but it also means fewer calories from added oil and more evenly cooked results every time.
