French Fried Onion Strings {Paleo/Gluten Free}

They may not look it, but these onion strings are about the best thing in the world! Perfect for any side dish year around.

Making fried onion strings is simple, but there are 3 crucial steps: 1) Slice the onions very thinly 2) Soak them in a vegan buttermilk mixture at least 1 hour, and 3) The oil must be the right temperature (I have instructions below to find the correct temp.)

Let’s get started 🙂


BTW – These go great with hamburgers or on top of my yummy green been casserole—SO good!
French Fried Onion Strings
  • 2 medium onions or 1 large onion
  • 2 C non-dairy milk
  • 2 t distilled white vinegar
  • 1 C blanched almond flour*
  • 1 C arrowroot or tapioca flour
  • 1 T salt
  • ¾ t black pepper
  • up to ½ tsp. cayenne, optional
  • coconut oil or non-hydrogenated shortening oil for frying
  1. Begin by peeling the onion and slicing it very thinly.
  2. Pour the milk and vinegar into a shallow dish and mix well.
  3. Separate the onion slices and place them in the shallow dish with the milk mixture. Press the onions down so they're submerged as much as possible and let them soak for at least an hour. I usually cover mine with foil and refrigerate them overnight.
  4. In a bowl, combine the blanched almond flour, arrowroot, salt, and pepper.
  5. Pour at least 2 inches of canola oil in a large pan and heat the oil to 375 degrees. If the oil isn't 375 degrees when you put the onions in they will either burn or not get crispy. An easy way to test the temperature is to throw one onion in and if it immediately sizzles but doesn't go crazy and start popping everywhere... it's good to go 🙂
  6. Using tongs, remove a handful of onions from the milk mixture and dunk them in the flour mixture. Coat the onions, shake off the excess, and place in the heated oil.
  7. Fiddle with them just a bit to break them up. When they are golden brown, only about a minute, remove them with a slotted spoon and place on a paper towel lined plate.
  8. Repeat with the remaining slices and serve immediately.

  1. *Rice Flour would also work well in place of the blanched almond flour.

    Hi there! I just came across this recipe and WOW. I made these fried onions to put in my green bean casserole. I’ve been vegan for years, but just developed a gluten allergy in the past year, so this is my first gluten-free Thanksgiving. I figured I’d give this a try, and if the onions didn’t work out, I’d buy some at the store and not eat any of my casserole this year. To my great delight, these onions are PERFECT. I’m looking forward to indulging in my casserole (and really pleased that I don’t have to go back to the store). Thank you so much for this recipe!

  2. I just made these onion strings for my Thanksgiving green bean casserole and your recipe was literally the highlight of everyone’s day! I started the gluten free lifestyle a year and a half ago and I have been so grateful to find recipes like yours. Thank you a million times over!
