  • Slice your onion super thinly.
  • Now fill a large bowl with buttermilk and drop the onion strings inside. Cover and set aside for an hour.
  • Mix up the flour, salt and pepper in another large bowl. Set aside till you are ready for it.
  • Turn on your deep fryer, or fill you dutch oven with oil. Never fill all the way to the top. You want to leave room for the food and the oil to bubble up as things cook. Nothing is worse than a grease fire so fill only ⅓ to ½ full if using dutch oven option. Bring the oil temperature up to 375 degrees F.
  • Uncover the onions and drain excess buttermilk mixture. Working in batches, dunk the onions in the flour mixture. Then drop them carefully into the oil. Cook until they are golden brown. This takes a few minutes, about 4 to 5 minutes. 
  • Use a spider tool to remove the onion strings from the oil. Pop them on a paper towel lined plate to drain off excess grease.
  • You can add some coarse salt over top while still hot if desired.
  • Serve with a big old onion-y smile!
