How to Make Air Fryer Crispy Onions
Step 1: Preheat and Prep
I start by preheating my air fryer to 375°F (190°C).
Next, I separate the onion slices into rings and toss with olive oil.
This light coat helps the flour cling for crisp edges.
This is how Air Fryer Crispy Onions start.
Step 2: Coat Onion Slices
In a bowl, I mix flour, garlic powder, onion powder, salt, and pepper for crispy onions.
Optional: add ¼ cup breadcrumbs for extra crunch.
I toss the onion slices in the flour mixture until evenly coated.
Shake off excess coating before laying in the basket.
Step 3: Air Fry and Shake
I arrange the coated onions in a single layer for even air fryer onions.
Air fry for 12 to 15 minutes, shaking halfway.
Look for golden edges and a crisp bite.
If your batch browns too fast, lower heat or shorten time.
Step 4: Cool and Use
I remove the onions and let them cool briefly.
A light sprinkle of salt finishes the job.
Now you have Air Fryer Crispy Onions ready for topping.
Store leftovers in a jar for snacks.
Tips for Success
- space Air Fryer Crispy Onions in a single layer; overcrowding steals crispness.
- I shake the basket halfway through; it evens browning and prevents soggy spots consistently.
- I adjust flour and breadcrumbs for gluten-free needs, keeping coating light and tasty every time.
- I add a pinch of smoked paprika or cayenne for warmth and depth per batch.
- I let onions cool briefly to maximize crispness before serving, then sprinkle salt.

Equipment Needed
- Air fryer with a 5–6 at basket for even crisps.
- Mixing bowls: one for coating, one for onions; glass or stainless.
- Measuring spoons and cups for accurate measurements, handy.
- Tongs or spatula for flipping and removing batches.
- Parchment paper or silicone liner (optional) to reduce sticking and make cleanup easier.
Variations
- Gluten-free version: use gluten-free flour and breadcrumbs. This keeps the coating tender and crispy, great for gluten-free eaters.
- Extra-crunch version: add an extra tablespoon of breadcrumbs. It gives a sturdier bite and more crunch on top of burgers and casseroles.
- Spicy kick: mix in smoked paprika, cayenne, or chipotle powder. Adjust heat to your family’s tolerance.
- Garlic lovers: increase garlic powder or add garlic salt. Pairs beautifully with caramelized onions if you like.
- Parmesan finish: toss with a light sprinkle of grated Parmesan after cooking. Cool slightly for the best texture.
