What You’ll Need to Make Onion Straws
- Large onions – thinly sliced
- Buttermilk – for that perfect soak
- All-purpose flour
- Whole wheat flour – adds a nice texture
- Salt
- Cayenne pepper – adjust to your spice level
- Smoked paprika – for a touch of smokiness
- Cornstarch – helps with that crispy finish
- Brown sugar – to balance the flavors
- Coconut oil spray – for air frying perfection
Let’s Get Cooking!
- Soak Those Onions: Start by soaking your thinly sliced onions in a bowl of buttermilk for about 30 minutes. This step not only helps soften the onions but also allows the flour to adhere better, creating a crispy crust.
- Mix the Dry Ingredients: In a separate bowl, combine the all-purpose flour, whole wheat flour, salt, cayenne pepper, smoked paprika, cornstarch, and brown sugar. This is where the magic happens—these ingredients will give your onion straws that irresistible flavor!
- Preheat the Air Fryer: While the onions are soaking, go ahead and preheat your air fryer to 375°F (190°C). This ensures your onion straws will cook evenly and get nice and crispy.
- Coat the Onion Straws: Take each soaked onion ring, letting any excess buttermilk drip off, and coat it thoroughly in your seasoned flour mixture. Make sure every inch is covered for maximum crunch!
- Air Fry Time: Place the coated onion straws in a single layer in the air fryer basket. Don’t overcrowd them; you want that hot air to circulate for the crispiest results. Lightly spray the coated onion straws with coconut oil spray—this little step is key to getting that golden-brown color!
- Cook to Perfection: Air fry those onion straws at 375°F for about 8-12 minutes, flipping them halfway through. Keep an eye on them; you want them crispy and golden!
- Cool and Serve: Once done, remove the onion straws from the air fryer and let them cool slightly. Serve them up with your favorite dipping sauce, like ketchup, aioli, or a spicy mayo. Trust me, they won’t last long!
And there you have it—your go-to recipe for crispy air fryer onion straws! These are a fantastic addition to any meal or just a tasty snack on their own. So grab those ingredients, fire up your air fryer, and enjoy the crunchy goodness!

Crispy Air Fryer Onion Straws
Equipment
- Airfyer
- Measuring Cups and Spoons
- Measuring Cups and Spoons
Ingredients
- 2 large onions (thinly sliced)
- 2 cups buttermilk
- ½ cup all-purpose flour
- ½ cup whole wheat flour
- 1 tsp salt
- 1 tsp cayenne pepper (adjust to taste)
- ½ tsp smoked paprika
- ¼ cup cornstarch
- 2 tsp Light Brown Sugar
- Coconut oil spray for air frying
Instructions
- Soak 2 large onions, that are scliced thin, in 2 cups buttermilk for 30 minutes.
- In a separate bowl, mix ½ cup all-purpose flour, ½ cup whole wheat flour, 1 tsp salt, 1 tsp cayenne pepper, ½ tsp smoked paprika, ¼ cup cornstarch and 2 tsp Light Brown Sugar.
- Preheat the air fryer to 375℉.
- Take each onion ring from the buttermilk, allowing excess liquid to drip off, and coat it thoroughly in the seasoned flour mixture, shaking off the excess. Smart people would do each onion ring with a fork, but I am not smart and use my fingers. Your fingers are going to get gross so have a bowl or water or a sink nearby.
- Place the coated onion straws in a single layer in the air fryer basket, ensuring they are not overcrowded to allow proper air circulation.
- Lightly spray the coated onion straws with cooking spray or mist with oil. This helps them crisp up in the air fryer. Air fry at 375°F (190°C) for about 8-12 minutes, flipping halfway through, until the onion straws are golden brown and crispy.
- Once done, remove the onion straws from the air fryer and let them cool slightly.
- Serve the air fryed onion straws with your favorite dipping sauce, such as ketchup, aioli, or a spicy mayo.
