Can I Use a Wet Batter to Make These Onion Rings with No Breadcrumbs?

While it’s not recommended to use a wet batter inside the air fryer, there are some alternatives that you can try.

For example, you could make your buttermilk by combining 1 cup of milk and one tablespoon of vinegar. Then, dip your onion slices in the milk before coating them in flour and breadcrumbs.

You could also try using an egg wash instead of a wet batter. Mix one egg and two tablespoons of water before dipping your onions in the mixture.

Finally, you could also use panko breadcrumbs instead of regular breadcrumbs. Panko crumbs are Japanese-style breadcrumbs made from dried, ground-up crustless white bread. They’re larger than traditional breadcrumbs, giving your onion rings more coverage and a crunchier texture.

How can I ensure my air fryer onion rings are crispy every time?

The best way to ensure your onion rings come out crispy every time is by spraying them with cooking spray before you put them in the air fryer. Which will help them get a nice, crispy coating.

Another critical tip is to work in batches when you’re cooking them. If you overcrowd the air fryer, they will not cook evenly and will likely be soggy.

One thing to note: the batter will get sticky, so it’s best to divide it into two parts. That way, it’ll be easier to work with. For extra flavor, you can add spices to the batter, such as garlic powder, cayenne pepper, or chili powder.

Halfway through cooking, spray the onion rings with cooking spray again to help them crisp up even more and achieve a deeper brown color. Do not turn the onion rings during the cooking process – they will cook evenly without flipping.

What is the secret to making perfect air fryer onion rings?

There is no perfect recipe for making air fryer onion rings-everybody has their own method that they swear by. However, a few tips and tricks will help you make the best onion rings possible.

  • The key to perfect onion rings is using olive oil. You can spray the onion ring batter with an aerosol propellant or use a brush to coat it in oil. If you don’t use oil, the bread crumbs will not adhere to the onion and will end up greasy.
  • Freezing the onion rings for a few minutes before breading them makes them sticky and easier to coat in bread crumbs. Make sure to handle them carefully, as the breading will come off if it’s not done correctly.
  • Frozen onion rings also help to prevent the breading from coming off during frying.
  • The best type of onion to use for air frying is a medium-sized onion.
  • Once you have coated the onions in batter, it’s essential to let the excess drip off before dipping them in a bowl of bread crumbs. Then, press the bread crumbs onto both sides of each ring until they are well coated.

How thick to slice Onion Rings?

Onion Rings are popular appetizers, and many enjoy their crispy texture. However, to ensure that your Onion Rings come out crispy every time, it is important to slice them into the correct thickness.

The best way to achieve perfectly crispy Onion Rings is to slice them into 1/4 to 1/2-inch thick slices. This will ensure that they cook evenly and come out nice and crisp every time.

Which Onions are Best for Making Onion Rings?

You can use a few different types of onions to make onion rings. The two most popular types are white and yellow onions. However, the third type of onion is becoming more popular lately because it has a sweet and bright flavor- the sweet onion.

Sweet onions are in season from Spring to Summer and can be used in place of white or yellow onions. Sweet onions have a milder flavor than white or yellow onions, so they are perfect for onion rings.

The spicy taste of white onions is not ideal for Onion Rings. In addition, white onions have a sharper bite than yellow or sweet onions, so they are not as good for making onion rings as the other two types of onions.

Yellow or white onions can be used in place of sweet onions if you do not have any on hand, but remember that white onions have a sharper bite than yellow or sweet onions.

How to Reheat Onion Rings in the Air Fryer?

Reheating onion rings in the air fryer is a fantastic way to revive their crispiness without turning them soggy. Follow these simple steps to ensure your leftover onion rings maintain their irresistible crunch.

Steps to Reheat Onion Rings in the Air Fryer:

1. Preheat Your Air Fryer:

Begin by preheating your air fryer to around 350°F (175°C). This ensures that the onion rings reheat evenly and regain their crispy exterior.

2. Arrange the Onion Rings:

Lay out the leftover onion rings in a single layer on the air fryer basket. Avoid overcrowding to allow proper air circulation, which is crucial for achieving that coveted crunch.

3. Spritz with Cooking Spray:

Lightly spritz the onion rings with cooking spray or lightly brush them with oil. This step helps enhance the crispiness during reheating, compensating for any moisture loss that might have occurred in the fridge.

4. Reheating Time:

Place the basket in the preheated air fryer and reheat the onion rings for 3-5 minutes. Keep an eye on them and shake the basket halfway through to ensure uniform crispiness.

5. Check for Crispiness:

After the initial 3-5 minutes, check the onion rings for their desired level of crispiness. If needed, you can add another minute or two, but be cautious not to overcook, as this can lead to excessive browning.

6. Serve Immediately:

Once the onion rings have reached the desired level of crispiness, remove them from the air fryer promptly. Serve immediately while they are at their peak, delivering that delightful crunch with each bite.

Tips for Reheating Onion Rings in the Air Fryer:

1. Avoid Microwave:

While a microwave is a quick option for reheating, it can make the onion rings soggy. The air fryer is the preferred method to maintain or restore the crispy texture.

2. Use Cooking Spray:

A light coating of cooking spray or a brush of oil can help rejuvenate the outer layer of the onion rings, contributing to their crispy finish.

3. Monitor Closely:

Keep a close eye on the reheating process, as air fryers vary in temperature and efficiency. Checking the onion rings periodically prevents overcooking and ensures they retain their initial quality.

4. Reheat in Batches:

If you have a large quantity of leftover onion rings, it’s better to reheat them in smaller batches. Overcrowding the air fryer can lead to uneven reheating.

5. Serve with Dipping Sauce:

Enhance the enjoyment of your reheated onion rings by serving them with your favorite dipping sauce. Whether it’s ketchup, aioli, or spicy mayo, a complementary sauce adds an extra layer of flavor.

Reheating onion rings in the air fryer allows you to enjoy them as if they were freshly made, with that satisfying crispy exterior that makes them an irresistible treat.

Can you Freeze Onion Rings?

Onion rings are a delicious appetizer or side dish, but sometimes you might end up with more than you can eat. Luckily, you can freeze onion rings for up to 8 weeks. This means you can cook them frozen in the air fryer, and they will come out crispy every time.

  • To freeze onion rings.
  • First, make sure they are completely dry.
  • Then place them on a baking sheet lined with parchment or wax paper.
  • Freeze for 2-3 hours or until solid.
  • Once frozen, place the onion rings in a freezer-safe bag or container and return them to the freezer.
  • When you’re ready to cook them, preheat your air fryer to 400 degrees F and cook for 10-12 minutes. Flip once halfway through cooking time. They will be crispy and delicious.


  • Make sure to spray the onion rings thoroughly with cooking spray before frying. This will help them to cook evenly and prevent them from sticking to the air fryer basket.
  • Work in batches to avoid overcrowding the air fryer and cook them evenly. If you try to cook too many onion rings at once, they will not cook evenly and will be soggy in the middle.
  • Air fryers have different capacities, so it may take more than two batches to make enough onion rings for your party or gathering.
  • It is best to divide the panko breadcrumb mixture in two so you can use one half for the batter and the other half for the coating. This will help ensure that each ring is coated evenly with breadcrumbs.
  • For extra flavor, add spices to the batter, such as garlic powder, cayenne pepper, or chili powder.
  • Onion rings should be placed in a single layer, not touching each other. This will help them to cook evenly and prevent them from sticking.
  • Air fryer onion rings should be cooked for about 15 minutes at 350 degrees Fahrenheit. Halfway through the cooking process, you can spray them with cooking spray to make them crisper and darker in color.
  • Onion rings will cook evenly without needing to be turned, making it easier to avoid sticking.
