Beer Battered Onion Rings

A super quick easy seven ingredient beer batter makes these Beer Battered Onions Rings so flavorful and crispy.  Dip in my six ingredient lime mayo and you will think you have a slice of heaven.


Lime Mayo Sauce

  • 1/3 cup mayo
  • 1 tablespoon ketchup
  • 1/4 teaspoon fresh ground black pepper
  • 1/8 teaspoon ground cayenne pepper
  • 1 small clove garlic finely minced
  • 1 tablespoon lime juice

Onion rings

  • 2 large sweet onions rough skins removed cut into 1/2-inch rings and separated
  • 1 1/4 cup all purpose flour
  • 1/4 teaspoon ground cayenne pepper
  • 1/4 teaspoon cumin
  • 1 teaspoon salt
  • 1/2 teaspoon fresh ground black pepper
  • 1 teaspoon garlic powder
  • 1 egg beaten
  • 1-1 1/2 cups beer
  • Vegetable oil for frying


  • In small bowl combine mayo, ketchup, 1/4 teaspoon black pepper, 1/8 teaspoon ground cayenne pepper, garlic and lime juice.
  • Set 1/4 cup of flour aside on a shallow plate. In medium bowl combine 1 cup flour, 1/4 teaspoon ground cayenne pepper, cumin, 1/2 teaspoon black pepper, garlic powder, beaten egg and 1 cup to 1 1/2 cups beer depending on how thick you want the batter.
  • Heat oil to 375 degrees. Dip onion rings in flour on shallow plate and then into batter. Fry battered onion rings in the hot oil until browned, about 4 minutes. Place on a paper towel covered wire rack while working in small batches.
  • Serve hot with Lime Mayo Sauce


  • Non-alcoholic beer or club soda can be substituted for the beer.
  • Sweet onions are the best for flavor, but honestly, any onion makes a decent onion ring.
  • I personally 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 till you get it to the consistency that you desire.
  • Use an oil with a high smoke point, like peanut oil, vegetable oil, or canola oil.
  • Try to maintain a consistent fry temperature of 375 degrees.  Use a candy or deep-fry thermometer. Dutch ovens are good heavy pans to fry in.  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.
