Ingredients

Scale
  • 2 large sweet onions, peeled and sliced into 1/2-inch rings (Vidalia, Walla Walla, or yellow onions)
  • 1 1/2 cups all-purpose flour
  • 1/2 cup cornstarch
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon salt, plus more for seasoning
  • 1/2 teaspoon black pepper
  • 1 teaspoon paprika
  • 1 1/4 cups cold sparkling water (or regular water)
  • Vegetable oil for frying (canola or peanut)
  • 1/2 cup ketchup
  • 12 teaspoons sriracha (to taste)
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • Dash of hot sauce (optional)
  • Pinch of sugar

Instructions

  1. Peel and slice the onions into 1/2-inch thick rings. Gently separate the rings and set aside. Discard the smallest inner rings.
  2. Pour vegetable oil into a heavy-bottomed pot or deep fryer until it’s 2 inches deep. Heat to 350°F.
  3. In a large mixing bowl, whisk together flour, cornstarch, baking powder, salt, black pepper, and paprika. Pour in cold sparkling water and whisk until smooth; batter should be thick but pourable.
  4. Lightly dust onion rings with a bit of flour. Dip each ring into the batter, coating evenly. Let excess batter drip off.
  5. Carefully place battered rings into hot oil, working in batches. Fry for 2–3 minutes per batch, turning once, until golden and crisp.
  6. Use a slotted spoon to lift out the rings and place them on a wire rack or paper towels. Sprinkle with a little extra salt while hot.
  7. Stir together ketchup, sriracha, smoked paprika, garlic powder, hot sauce (if using), and sugar in a small bowl. Taste and adjust heat to preference.
  8. Pile onion rings onto a platter and serve hot with spicy ketchup for dipping.

Notes

For best crunch, use fresh cornstarch and flour. Dry onion slices before battering to help the coating stick. Fry in small batches to keep oil temperature steady. For gluten-free, use a GF flour blend and arrowroot instead of cornstarch. Double-dip for extra crunch. Reheat leftovers in the oven or air fryer for best texture.
