  • 2.5 cups Homemade (or store bought) Buttermilk
  • 4 cups Thinly sliced onions, halves and rings of small onions
  • 3 cups All purpose flour
  • 1 tsp Kosher salt
  • 1/4 tsp Fresh ground pepper
  • 4 cups Vegetable oil


  • Soak onions in buttermilk for at least 10 minutes. 
  • In a shallow dish add flour, salt, and pepper and mix well. 
  • In a large pan heat vegetable oil to 375 degrees.  To test to see if your oil is ready for frying, dip the handle of a wooden spoon in the oil and if it bubbles around the handle then it's ready.
  • Dredge buttermilk soaked onions in flour until well coated and add to oil, frying in batches until golden brown then remove form oil with a slotted spoon and drain on a paper towel lined plate.  Continue with all of the onions with additional paper towel lined plates after a double layer of onions are on one.  
  • Use immediately or store in an airtight container in a dry cool place for up to a few days.



Let cool completely then store in an airtight container in the fridge for up to 3 days.  To crisp back up (if needed) bake in the oven for 5 minutes at 375 degrees.
Make it gluten-free by using gluten-free flour. 
Make it vegan by using plant-based milk and 2 1/2 teaspoons of vinegar.
