  • 2 whole large sweet onions Vidalia if available
  • 2 cups buttermilk
  • 2 cups all-purpose flour
  • 1 Tbsp kosher salt
  • 1/2 tsp ground red pepper
  • 2 cups peanut oil or other vegetable oil


  • Peel and slice the onions as thin as possible. Separate the rings.
  • Place the onion rings in a shallow bowl and cover with buttermilk. Allow the onions to soak in the buttermilk for at least an hour.
  • Combine the flour, salt and red pepper in a shallow bowl.
  • Preheat the oil in a dutch oven or large frying pan to 360 degrees F.
  • When the oil is hot, take a handful of the onion rings and dredge them in the flour mixture. Shake off any excess flour and add to the hot oil. Fry for 1-2 minutes or until they are golden brown. Watch the onion rings carefully, they can go from perfect to burned in a matter of seconds. Repeat as needed until all of the onion rings are cooked. Drain on paper towels.
  • Serve immediately while they are still hot.


If you need to keep the onion rings warm, preheat your oven to 225 degrees and put them on an oven proof plate for up to 30 minutes or until you are ready to serve them.
