How to Make French Fried Onions


  • 1 large onion
  • 2 cups buttermilk
  • 2 cups all-purpose flour
  • 1 tablespoon salt
  • 1 quart canola oil (about 4 cups)
  • Salt and pepper, to taste


  1. With a sharp knife, slice the onion into very thin rings. Place onions in a bowl with buttermilk. Cover and soak for at least an hour.
  2. Heat oil in a pan until it reaches 375 degrees F, using a candy or oil thermometer to measure.
  3. Meanwhile, combine flour and salt in a medium bowl and set aside.
  4. Working in batches, use tongs to grab a handful of onions and place them in the flour, coating well. Shake off excess flour and plunge into the hot oil. Fry until golden brown, about 6 to 8 minutes. Remove and place on a paper towel-lined plate.
  5. Repeat with remaining onions. Sprinkle with additional salt and pepper as desired. Serve immediately.

Yumm. These onion rings look just like the onion rings served at a famous chain restaurant here in South Africa. I always wanted to know how to make them. They go so well with a steak. I'm going to make these for sure! These might go well as a topping for the McMuffin breakfast casserole recipe on this site as well.

Onion is good with everything in my book but fried onions...oh my goodness, I can eat them by themselves or with anything especially on a burger! I've never tried using buttermilk before...usually, I just coat them with corn starch and toss them in the fryer. Definitely, need to give this recipe a try.

These look so yummy! I am an onion fiend, so I am eager to give these a shot. The tip about soaking the onions in buttermilk is a really good one. I used that to make homemade onion rings and it really does make a difference. I think that these would be delicious on top of a big juicy homemade hamburger fresh of the grill this summer. Can't wait to try them!
