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 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. Simply 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.

  • 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.
