Super Crispy Onion Rings

Recipe by Sharon123
READY IN: 30mins


  • 2
    quarts vegetable oil, for frying
  • 3
    cups flour (cake flour is best)
  • 2
    teaspoons baking soda
  • 2
    teaspoons salt, plus more for sprinkling (use kosher if possible)
  • 2 12 - 3
    cups chilled club soda
  • 2
    large Spanish onions, cut into 1/2-inch slices and separated into rings


  • In a very large pot (or deep fryer), heat the oil to 365°.
  • In a bowl, whisk the flour with the cornstarch, baking soda and 2 teaspoons of salt.
  • Add 2 1/2 cups of the club soda and whisk until smooth; the batter should be thick but pourable. If needed, add the remaining 1/2 cup of club soda, a few tablespoons at a time.
  • Working with 6 or 7 onion rings at a time, dip them in the batter until completely coated; as you pull the rings from the batter, scrape some of the excess against the side of the bowl.
  • Carefully add the onion rings to the hot oil and fry until golden and crisp, about 2 minutes.
  • Drain the onion rings on paper towels.
  • Sprinkle the onion rings with salt and serve immediately or keep warm in an oven on low heat while you coat and fry the rest. Enjoy!
