Air Fryer Crispy Onion Strings Recipe
A Crispy Snack I Make Again and Again
I honestly didn’t expect onions to become one of my favorite air fryer recipes, but these crispy onion strings completely changed my mind. I usually make a big batch whenever we’re having burgers, sandwiches, or salads because everyone grabs a handful before dinner is even ready. They’re perfectly crunchy, lightly seasoned, and so much healthier than deep-fried onions.
The best part? The air fryer does most of the work, giving you golden, crispy onions with only a little oil.
Ingredients
- 2 large sweet onions, thinly sliced into rings
- 1 tablespoon olive oil
- ½ cup all-purpose flour
- 2 tablespoons cornstarch
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Cooking spray (optional)
Step-by-Step Instructions
Step 1: Slice the Onions
Peel the onions and slice them into thin rings. Separate each ring gently.
Step 2: Season the Coating
In a large bowl, combine the flour, cornstarch, garlic powder, paprika, onion powder, salt, and black pepper.
Step 3: Coat the Onion Rings
Drizzle the onion rings with olive oil and toss until lightly coated. Add them to the flour mixture and toss until every ring is evenly coated.
Step 4: Prepare the Air Fryer
Preheat your air fryer to 375°F (190°C) for about 3 minutes.
Step 5: Air Fry
Arrange the onion strings in a single layer inside the air fryer basket. Don’t overcrowd them, as this helps them crisp evenly.
Air fry for 10–14 minutes, shaking the basket every 4–5 minutes. If needed, lightly spray with cooking oil halfway through cooking.
Step 6: Cool Before Serving
Once they’re golden brown and crispy, transfer them to a plate and let them cool for a few minutes. They’ll become even crispier as they cool.
Cooking Tips
- Slice the onions as thinly as possible for maximum crispiness.
- Cook in batches instead of overcrowding the basket.
- Cornstarch helps create a lighter, crunchier texture.
- Shake the basket several times while cooking.
- Watch closely during the final few minutes since onions can brown quickly.

Frequently Asked Questions
1. Can I make these without flour?
Yes! You can use cornstarch alone or substitute almond flour or gluten-free flour for a different texture.
2. How do I keep onion strings crispy?
Allow them to cool on a wire rack instead of stacking them. This helps prevent steam from softening the coating.
3. Can I store leftovers?
Yes. Store cooled onion strings in an airtight container for up to 2 days and reheat them in the air fryer for 2–3 minutes.
4. Which onions work best?
Sweet onions like Vidalia or yellow onions give the best balance of sweetness and crispiness.
5. Can I freeze cooked onion strings?
Yes. Freeze them in a single layer, then reheat directly in the air fryer at 350°F (175°C) for 4–5 minutes until crispy again.
