Frizzled Onions Recipe
Introduction
Frizzled onions are crispy, golden, and full of savory flavor, making them a perfect topping for burgers, salads, or just a tasty snack on their own. This simple recipe turns thinly sliced onions into irresistible crispy bites with a light buttermilk coating.

Ingredients
- ½ pound yellow onions (2 to 3 small, very thinly sliced and separated into individual rings)
- 1½ cups buttermilk
- 1½ cups all-purpose flour
- 1 teaspoon salt
- Canola oil (for frying, amount will vary according to the size of your pot)
Instructions
- Step 1: Add the sliced onions and buttermilk to a large bowl. Allow the onion slices to soak in the buttermilk for 1 hour.
- Step 2: In a shallow dish, add the all-purpose flour and salt. Stir to combine.
- Step 3: Remove a handful of the buttermilk-coated onion slices, letting any excess buttermilk drip back into the bowl. Add the onion slices to the dish of flour and toss to coat evenly.
- Step 4: Shake off any excess flour from the coated onions and place them on a plate. Repeat steps 3 and 4 until all onions are coated.
- Step 5: Heat canola oil in a large, heavy-duty pot to 375°F. Use a candy thermometer to monitor the temperature.
- Step 6: Fry about a third of the flour-coated onions in the hot oil for 1½ to 2½ minutes, until lightly golden and crispy.
- Step 7: Use a slotted spoon or spider strainer to remove the fried onions and transfer them to a paper towel-lined plate to drain excess oil.
- Step 8: Repeat frying and draining with the remaining onions until all are cooked.
Tips & Variations
- For extra crispiness, double dredge the onions by dipping them back into buttermilk and flour before frying.
- Try adding a pinch of smoked paprika or cayenne pepper to the flour for a smoky or spicy twist.
- Use vegetable or peanut oil if you prefer a different frying oil with a high smoke point.
- Make sure the oil is hot enough to avoid soggy onions; frying at 375°F helps achieve perfect crispiness.
Storage
Store leftover frizzled onions in an airtight container at room temperature for up to 1 day to keep them crispy. Reheat briefly in a hot oven or air fryer to refresh their crunch. Avoid refrigerating as moisture will make them soggy.

FAQs
Can I use regular milk instead of buttermilk?
Buttermilk helps tenderize the onions and adds a slight tang, but you can substitute regular milk mixed with a tablespoon of lemon juice or vinegar to mimic buttermilk’s acidity.
How thin should the onion slices be?
Slice the onions very thinly, about 1/8 inch thick or less, so they fry quickly and become crispy without burning.

Frizzled Onions Recipe
- Total Time: 1 hour 30 minutes
- Yield: About 2 cups of frizzled onions 1x
Description
Crispy, golden frizzled onions made by soaking thinly sliced onions in buttermilk, coating them in seasoned flour, and deep-frying until perfectly crunchy. These onions make a delightful topping for salads, steaks, and casseroles or a tasty snack on their own.
Ingredients
Onion Mixture
- ½ pound yellow onions (2 to 3 small), very thinly sliced and separated into individual rings
- 1½ cups buttermilk
Dry Coating
- 1½ cups all-purpose flour
- 1 teaspoon salt
For Frying
- Canola oil, amount as needed for deep frying (enough to fill a large heavy-duty pot to about 2-3 inches deep)
Instructions
- Soak Onions: Add the thinly sliced onions and buttermilk to a large bowl. Let the onions soak for 1 hour, allowing the buttermilk to soften and coat them thoroughly.
- Prepare Flour Mixture: In a shallow dish, combine the all-purpose flour and salt, stirring well to evenly distribute the seasoning.
- Coat Onions: Remove a handful of the soaked onion slices from the buttermilk, letting excess liquid drip back into the bowl. Toss the onion slices in the flour mixture until fully coated.
- Shake Off Excess Flour: Lift the flour-coated onions and gently shake off any surplus flour. Place them on a plate. Repeat the coating process in batches until all onions are prepared.
- Heat Oil: Pour canola oil into a large, heavy-duty pot to a depth of about 2-3 inches and heat it to 375°F, using a candy thermometer to ensure precise temperature.
- Fry Onions: Carefully add about a third of the coated onions into the hot oil. Fry for 1½ to 2½ minutes or until the onions become lightly golden and crispy.
- Drain and Repeat: Use a slotted spoon or spider strainer to remove the onions from oil. Transfer them onto a paper towel-lined plate to drain excess oil. Repeat frying in batches until all onions are cooked.
Notes
- Thinly slicing the onions is critical for achieving maximum crispiness.
- Maintaining the oil temperature at 375°F ensures the onions fry quickly and absorb less oil.
- Use a heavy-duty pot to keep oil temperature stable during frying.
- These fried onions can be stored in an airtight container for a day but are best enjoyed fresh.
- Can be used as a topping for salads, burgers, sandwiches, or green bean casseroles.
