Ingredients:

  • 1 cup buttermilk
  • 1 large yellow onion, sliced into 1/4-inch rings
  • 1 cup all-purpose flour
  • 1/2 cup cornstarch
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp paprika
  • 1/4 tsp cayenne pepper
  • 1 cup Panko breadcrumbs
  • 3 cups vegetable oil

Instructions:

  1. Slice the onion into uniform 1/4-inch rings and submerge them in buttermilk. Let them soak for 10 minutes.
  2. In a mixing bowl, whisk together the all-purpose flour, cornstarch, salt, black pepper, paprika, and cayenne pepper until well combined.
  3. Remove onions from the buttermilk and toss them in the seasoned flour mixture, shaking off any excess.
  4. For extra crispiness, dip the floured rings back into the buttermilk briefly, then press them firmly into the Panko breadcrumbs.
  5. Heat vegetable oil in a cast iron skillet or deep fryer to 350°F (175°C).
  6. Fry onion rings in batches of 4-5 for 2-3 minutes per side until they reach a deep mahogany color.
  7. Transfer fried rings to a wire cooling rack and drain on paper towels.
