Follow The Directions

01

Step

5 mins

Preheat your air fryer to 375 degrees F (190 degrees C) following the manufacturer's instructions. (5 minutes)

02

Step

2 mins

In a medium bowl, whisk together the flour, cayenne pepper, and a generous pinch of salt. (2 minutes)

03

Step

3 mins

Add the thinly sliced onions to the bowl and toss until each strand is evenly coated with the flour mixture. Ensure no clumps remain. (3 minutes)

04

Step

2 mins

Arrange the coated onions in a single layer in the air fryer basket. Avoid overcrowding for optimal crisping. Lightly spray the onions with cooking spray. (2 minutes)

05

Step

23 mins

Air fry for 18 to 23 minutes, shaking the basket every 4 to 5 minutes to ensure even cooking and prevent sticking. The onions are done when they are a deep golden brown and crispy. (23 minutes)

For extra flavor, consider adding a pinch of garlic powder or smoked paprika to the flour mixture.
To reduce the onion's sharpness, soak the sliced onions in ice water for 15 minutes before coating.
Store leftover crispy onions in an airtight container at room temperature to maintain their crispness. They are best enjoyed within a few days.
