Ingredients You’ll Need
Each ingredient in this recipe plays a crucial role in creating that perfect balance of flavor and crispness. With just a handful of everyday pantry staples, you’ll craft onions that are tender on the inside, crispy on the outside, and bursting with savory notes.
- 2 medium onions (sliced thinly): The star of the show; thin slices create maximum crispiness once fried.
- 1 cup buttermilk (for soaking): Adds tang and helps tenderize the onions for a melt-in-your-mouth texture.
- 1 cup all-purpose flour: Forms the crispy coating; can swap with gluten-free flour if needed.
- 1 teaspoon garlic powder: Infuses a subtle savory depth to the coating.
- 1 teaspoon onion powder: Doubles down on onion flavor for that extra punch.
- 1 teaspoon paprika: Adds a smoky, vibrant color and slight warmth.
- A pinch salt: Enhances all the flavors and balances the seasoning.
- Cooking spray (as needed): Ensures the onions crisp up beautifully without sticking.
How to Make Crispy Fried Onions in the Air Fryer Recipe
Step 1: Soak the Onions
Start by soaking your thinly sliced onions in a cup of buttermilk for at least 30 minutes. This simple step softens the onions, making them tender and juicy, while the buttermilk adds a delicious tang. It’s a game changer that ensures the onions aren’t just crispy, but also melt-in-your-mouth delightful inside.
Step 2: Prepare the Flour Coating
While the onions soak, mix together your flour, garlic powder, onion powder, paprika, and salt in a bowl. Whisking these dry ingredients well helps create an even and flavorful coating that will cling perfectly to each onion slice. This seasoning mix gives the onions a robust and balanced taste that shines through the crispiness.
Step 3: Preheat Your Air Fryer
Preheating the air fryer to 350°F (175°C) for about 5 minutes sets the stage for even cooking and perfect crunch. It’s a small step but key to ensuring the onions fry quickly and beautifully golden, not soggy or undercooked.
Step 4: Coat the Onions
Drain your onions from the buttermilk and toss them in the seasoned flour mixture until each slice is evenly coated in a thin, crispy layer. Be gentle but thorough so the flour mix sticks without clumping, which makes for the best crunchy bites.
Step 5: Air Fry to Perfection
Spray the air fryer basket with a little cooking spray to prevent sticking. Lay the coated onion slices in a single layer for even cooking, spritz the tops lightly with spray, and air fry for 10 to 15 minutes. Don’t forget to give the basket a good shake halfway through to cook the onions on all sides evenly. When they reach a gorgeous golden brown and snap with crispiness, you know they’re done!

Make Ahead and Storage
Storing Leftovers
If you have any crispy fried onions left over, store them in an airtight container at room temperature to maintain their crunch for up to 2 days. Avoid refrigerating, as the moisture can soften the crisp texture you worked so hard to achieve.
Freezing
You can freeze these onions by spreading them out on a baking sheet to freeze individually, then transferring them to a freezer bag. When stored properly, they keep well for up to a month. This trick makes sure you can enjoy your favorite crispy topping anytime without starting from scratch.
Reheating
To bring back their delightful crispiness, reheat leftover onions in the air fryer for 2 to 3 minutes at 350°F. This quick refresh restores their crunchy texture without drying them out or making them greasy.
FAQs
Can I use other types of onions for this recipe?
Absolutely! While yellow onions are classic for their balance of sweetness and sharpness, sweet onions or even red onions can work beautifully and bring subtle flavor variations. Just slice them thinly for the best crisp.
Is it necessary to soak onions in buttermilk?
Soaking the onions in buttermilk helps tenderize them and adds a subtle tang, which enhances the overall flavor. If you don’t have buttermilk, you can use milk with a teaspoon of vinegar as a substitute or skip it, but the texture might be less tender inside.
Can I make this recipe gluten-free?
Yes, you can swap all-purpose flour for your favorite gluten-free flour blend to make this recipe gluten-free. Just ensure the blend has a good binding quality for best results in crispiness.
What if I don’t have an air fryer? Can I make these in the oven?
Yes, you can bake these crispy fried onions in the oven at 400°F for 15 to 20 minutes, turning them halfway through. Just keep an eye on them to avoid burning since ovens cook differently than air fryers.
Why are my fried onions not crispy?
To achieve maximum crispiness, make sure to slice onions thinly and coat them evenly without clumps. Preheating the air fryer and avoiding overcrowding the basket are also important. Overcrowding traps moisture, making them soggy instead of crisp.
