These beer-battered onion rings are the most delicious way to prepare them. The beer batter takes just a few minutes to prepare, and the onion rings are exceptionally good every time, with excellent flavor and crispiness!

Crunchy, golden, and fried to perfection, they will quickly become a favorite snack and side dish. I like to serve this with lime mayo sauce, boom boom sauce, comeback sauce, yum yum sauce, or sweet and sour sauce.
My husband is an absolute fanatic when it comes to crispy onion rings. He LOVES THEM!! Now, add some beer batter, and he thinks he has died and gone to heaven. Unsurprisingly, he was munching down these like there was no tomorrow. They are so easy; you can cook them in a deep fryer or a heavy pan like a Dutch oven using a thermometer. The sweet lime mayo dipping sauce quickly comes together and can be prepared beforehand.
Ingredient Notes and Substitutions
See the complete list of ingredients below on the recipe card.
- Onions: Sweet onions are the best for flavor, but honestly, any onion makes a decent ring.
- Seasonings: ground cayenne pepper, ground cumin, salt, freshly ground black pepper, and garlic powder
- Beer: a non-light, mildly flavored beer. Now is not the time for a chocolate coffee stout. You can substitute non-alcoholic beer or club soda for the beer.
- Vegetable oil: canola or peanut oil
- Mayonnaise: I use Duke’s, but you can use any may
How To Make Beer-Battered Onion Rings
This is the nutshell version. See the recipe card below for the complete list of ingredients and instructions.
First, mix the mayo, ketchup, black pepper, cayenne pepper, garlic, and lime juice. Place some flour on a shallow plate and mix your beer batter.
Heat the oil in a large, heavy pot like a Dutch oven or deep fryer. Dip the onion rings in the flour and dunk them in the beer batter. Fry in the oil until golden brown, working in small batches. Drain the excess grease on a paper towel-covered wire rack and serve with the homemade lime mayo sauce.

Preparation Tips and Storage
- I like working with the batter when it is thin, so I use 1 1/2 cups of beer. You can start with 1 cup and add more as you work with it until you achieve the desired consistency.
- Use oil with a high smoking point, like peanut, vegetable, or canola.
- Try to maintain a consistent fry temperature of 375 degrees. Use a candy or deep-fry thermometer. Dutch ovens are good, heavy pans for frying. Because of their thickness, they maintain and hold heat well.
- Store leftover onion rings in an airtight container in the refrigerator. For best results, reheat them in the air fryer for 2-3 minutes.

Frequently Asked Questions
My favorite is the sweet Vidalia Onion, followed by the sweet Walla Walla Onion. Almost all Vidalia Onions are grown within seventy-five miles of Vidalia, Georgia. Walla Walla Onions are grown in Walla Walla County, Washington State.
These sweet onions make delectable onion rings; however, you can use yellow and white onions. They are a little stronger but still make awesome onion rings.
My favorite is Sam Adams Boston Lager, but any beer will do the trick. A Belgian-style tripel will lend a little sweetness to your onion rings, and generally speaking, the non-light beers will lend more flavor and add more crispiness to your rings.

You might be able to help me… at least I hope. I love onion rings but I am no longer able to fry them in grease due to serious health restrictions. Do you know how I can make them in the oven, or airfryer without grease? I would love a response – hopefully with a help. Thanks in advance

Wet batter onion rings do not cook well in anything but oil. However you might want to try my air fryer onion rings. They are delicious without all the ill effects of oil.
