Make restaurant-style, ultra crispy onion rings at home using a simple beer batter. This recipe delivers a crunchy coating perfect for serving with burgers or as a game day snack.

Ingredients

Scale
  • 2 large yellow onions
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup cold beer (lager or pilsner recommended)
  • 1/4 cup all-purpose flour (for dredging)
  • Vegetable oil, for frying

Instructions

  1. Slice the onions into 1/4-inch thick rings. Separate the rings and set them aside.
  2. In a medium bowl, whisk together 1 cup flour, baking powder, salt, and pepper for the batter.
  3. Slowly pour in the cold beer while whisking until you have a smooth batter, similar in consistency to pancake batter. Do not overmix; a few small lumps are fine.
  4. Pour about 2 inches of vegetable oil into a deep, heavy-bottomed pot or Dutch oven. Heat the oil to 375 degrees Fahrenheit (190 degrees Celsius). Use a thermometer to monitor the temperature.
  5. Place the 1/4 cup of dredging flour in a shallow dish. Lightly dust the onion rings in this flour, shaking off any excess. This step helps the batter stick.
  6. Dip the floured onion rings into the beer batter, coating them completely. Let any excess batter drip off briefly.
  7. Carefully place the battered rings into the hot oil, working in small batches to avoid overcrowding the pot. Overcrowding lowers the oil temperature and results in soggy rings.
  8. Fry for 2 to 3 minutes per side, turning occasionally, until they are deep golden brown and very crispy.
  9. Remove the onion rings with a slotted spoon and place them on a wire rack set over a baking sheet lined with paper towels to drain excess oil.
  10. Immediately sprinkle the hot onion rings with a pinch of salt. Serve hot with your favorite dipping sauce.

Notes

  • For the crispiest results, make sure your beer is very cold before mixing the batter.
  • If you do not want to use beer, substitute it with club soda or sparkling water for carbonation.
  • Maintain the oil temperature between 365F and 375F for consistent crunch.
