  • 5 large sweet onions, peeled and sliced into 1" rings
  • neutral flavored oil (vegetable recommended)
  • for seasoned flour mixture:
  • 2 1/2 cups flour
  • 1 1/4 cup cornmeal
  • 1 cup cornstarch
  • 1/2 cup baking powder
  • 3-4 tablespoons Kansas City Rub or your favorite bottled rub
  • 1 teaspoon salt
  • Dredge:
  • 2 1/2 cups flour
  • Liquid Mixture:
  • 1 1/2 cups buttermilk
  • 1 1/4 cups whole milk


  • Cut onions into rings and place into a large bowl filled with cool water.
  • Scoop out plain flour and set aside. Combine the liquid mixture and set aside. Do the same for the seasoned flour mixture. This will be a 3 step dredging process.
  • Remove onions from water and place onto a clean kitchen towel or a paper towel lined tray.
  • Heat about 3- 3 1/2 " of oil in a large skillet. If you have a deep fryer, follow manufacturer's instructions. Once temperature of oil reaches between 340-350 degrees F., it is time to start dredging and frying.
  • Dip onion rings into plain flour, then liquid mixture, then into seasoned flour mixture. Drop about 4 or 5 rings into the oil and cook for 2- 2 1/2 minutes, or until they are golden brown and crunchy. Scoop out with a large slotted spoon (or heat resistant spatula) onto a paper towel lined tray. Season with a little salt. Repeat process for the next several batches.
