Ingredients Method Notes

Ingredients
  

  • 1 large yellow onion
  • 1 cup all-purpose flour
  • 1/4 cup cornstarch
  • 1 tsp baking powder
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp paprika
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1 cup buttermilk
  • 1 large egg
  • Vegetable oil for frying (about 3 to 4 cups)

Method
 

  1. Peel and slice the onion into 1/2-inch rounds, separate into rings, and pat completely dry on paper towels.
  2. Whisk together the flour, cornstarch, baking powder, garlic powder, onion powder, paprika, salt, and pepper in a large bowl. Beat the egg into the buttermilk, pour into the dry ingredients, whisk until smooth, and refrigerate the batter for 10 minutes.
  3. Heat 3 inches of vegetable oil in a heavy-bottomed pot over medium-high heat to 375°F (190°C).
  4. Dip each ring in the cold batter, let the excess drip off, then fry in batches of 4 to 5 rings for 2 to 3 minutes, turning once, until deep golden brown. Drain on a wire rack.
  5. Sprinkle with a pinch of salt while hot, pile onto a plate, and serve immediately with your dipping sauce.

Notes

These are best eaten right away, within about 10 minutes of frying. If you're making them for a group, keep finished batches on a wire rack in a 250°F (120°C) oven while you fry the rest. The batter recipe makes enough for 1 large onion with a little left over; if your onion is on the small side, you may have batter to spare.
