Onion Rings


Delicately battered onion rings can be made at home without fuss; seltzer, or carbonated water, is the secret ingredient. Fried parsley adds a steakhouse flourish.

Source: Everyday Food, July/August 2007


  • 1 Vidalia onion, sliced crosswise into thin rings
  • 1 1/4 cups all-purpose flour (spooned and leveled)
  • 1/2 cup cornstarch
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon coarse salt
  • 1 can (12 ounces) seltzer or other carbonated water
  • 6 cups vegetable oil
  • Coarse salt
  • 1/2 cup fresh parsley leaves, washed and dried very well


  1. Line a baking sheet with paper towels; set aside. Place onion rings in a large bowl of ice water for 10 minutes; drain and pat dry. In a large bowl, whisk together flour, cornstarch, baking powder, salt, and seltzer.

  2. In a heavy 5-quart pot or Dutch oven, heat oil over high until a deep-fry thermometer registers 375 degrees. Working in 7 to 8 batches, place onions in batter; using your fingers, lift out, letting excess drip off. Carefully place in oil, making sure not to overcrowd pot; cook until golden brown, 2 to 3 minutes.

  3. Transfer rings to prepared baking sheet, and season with salt. Keep warm in a 250-degree oven. Return oil to 375 degrees before starting next batch.

  4. Once all the onion rings are done, place on a platter. Very carefully place parsley in pot (oil will spatter), and fry until crisp, 10 seconds; remove, using a spider or slotted spoon, and season with salt. Sprinkle onions with parsley.

Cook's Notes

A spider -- a wide and shallow wire skimmer -- is the best tool for removing onion rings and fried parsley from the hot oil; if you don't have one, use a big slotted spoon.

    In the episode Martha stated that she used beer and called it beer batter for the onion rings. Why does the recipe say seltzer water??? Honestly, I find it annoying when the recipe is different from the show. I made them using beer and some water, only because I didn't have enough beer. I only had a 7oz beer bottle so I used water for the remaining four ounces. They came out good.
