You are in luck because not only is this ingredient list short and simple, but it’s full of ingredients that you probably already have in your kitchen! Check out the recipe card at the bottom of the post for exact measurements.

  • Oil: This is for frying your onions in! Vegetable oil or canola oil work great.

  • Buttermilk: You can use storebought buttermilk or you can easily make it at home with this recipe and it’s just as good!
  • Flour: All purpose flour works great to coat your onions.
  • Seasonings: To make these onions so delicious you will use garlic powder, onion powder, paprika, salt and ground black pepper.
