homemade crispy fried onion string recipe

Homemade Fried Onion Strings

  • Author: Jess Pryles
  • Total Time: 50 minutes
  • Yield: serves 2-4 1x



2 large sweet or yellow onions
1 pint buttermilk (16 fl oz)
2.5 cups AP flour
¼ cup Hardcore Carnivore Red seasoning
4-6 cups peanut, canola or vegetable oil for frying


  1. Peel and finely slice an onion into ⅛” thick slices. I recommend using a mandoline for this to get thin slices. 
  2. Place the sliced onions into a non-reactive bowl, and pour over the buttermilk, making sure everything is submerged. Soak the onions in the buttermilk for 30-60 minutes. 
  3. In a large bowl or resealable bag, place the flour and seasoning, and mix well.
  4. Place the oil into a high sided pot, and place over high heat. Heat to 375f. 
  5. Drain the onions, then take a handful of onions and drop them into the flour mixture. Toss them in the flour to coat, then shake off any excess and lower into the hot oil. 
  6. Fry for 2-3 minutes until golden and crispy. Then use a spider or slotted spoon to remove them, and place them onto a rack to drain any excess oil. 
  7. Repeat the process in batches until all onions are fried. Wait for the oil to come back up to temperature between each batch. 
  8. Best served 3-5 minutes after frying, or hold them on the rack until ready to use – this applies to same day use only. You can reheat them for 5-10 minutes in a 400f oven if desired.
