How to Cut Onions for Crispy Air Fryer Onions
For the best results, slice the onions as evenly as possible.
Using a Mandoline
Peel the onion and trim one end while leaving the root end intact. Slice the onion into thin rounds, approximately 3mm thick. A mandoline helps create uniform slices that cook evenly.
Using a Knife
If you don’t have a mandoline, use a sharp knife and carefully cut thin, even slices.
After slicing, gently separate the onion rings before coating them with oil.
How to Make Air Fryer Crispy Onions
Step 1: Preheat the Air Fryer
Preheat your air fryer to 300°F (150°C) if your model has a preheat setting.
Step 2: Prepare the Onions
Place the sliced onions in a bowl and drizzle with cooking oil. Toss gently until all the onion rings are lightly coated.
Step 3: Add to Air Fryer
Spread the onion rings evenly in the air fryer basket.
Step 4: First Cooking Stage
Air fry at 300°F for 10 minutes.
After 5 minutes, gently shake or stir the onions to ensure even cooking.
Step 5: Lower the Temperature
Reduce the temperature to 240°F (115°C).
Continue cooking for an additional 15 to 18 minutes, stirring every 5 minutes.
Step 6: Check for Crispiness
Once the onions are golden brown and crispy, remove them from the air fryer.
Step 7: Cool Completely
Allow the onions to cool for several minutes. They will become even crispier as they cool.
