Golden Crispy Onion Rings

Course Snack
Prep Time 20 minutes
Cook Time 15 minutes
Total Time 35 minutes

Ingredients

  • 1 quart vegetable oil for frying
  • 2 large Spanish onions sliced crosswise into ½-inch rings
  • 2 teaspoons kosher salt plus extra for seasoning
  • 3 to 4 cups chilled club soda
  • 1 teaspoon baking powder
  • 3 cups all-purpose flour
  • ⅓ cup cornstarch

Instructions

  1. In a large mixing bowl, whisk together the flour, cornstarch, baking powder, and 2 teaspoons of kosher salt until evenly combined.
  2. Gradually pour in 3 cups of chilled club soda while whisking continuously until the batter becomes smooth. If needed, add a little more club soda, one tablespoon at a time, until the batter reaches the consistency of a thin pancake batter. Let it rest for 10 minutes.
  3. Pour the vegetable oil into a large, heavy-bottomed saucepan or deep fryer. Heat the oil to 380°F (193°C).
  4. Separate the onion slices into individual rings. Dip a small batch of onion rings into the batter, allowing any excess batter to drip back into the bowl.
  5. Carefully place the battered onion rings into the hot oil. Fry for about 3 minutes, turning occasionally, until they become golden brown and crisp.
  6. Remove the onion rings with a slotted spoon and place them on a paper towel-lined tray to drain excess oil. Sprinkle lightly with salt while still hot.
  7. Repeat with the remaining onion rings.
