Tips for Air Fryer Crispy Onions recipe
– One of the best tips for perfect Air Fryer Crispy Onions is slicing the onions evenly.
– Uneven slices can cause some pieces to burn while others stay soft. If you’re short on time, a mandoline slicer makes this step fast and easy.
– Another helpful tip is to cook the onions in batches. Overcrowding the air fryer basket traps moisture, which makes the onions soft instead of crispy.

– It may take a little longer to cook in batches, but the texture will be much better.
– If you want extra crunch, you can add a little more cornstarch, but don’t overdo it. Too much can leave a powdery taste. For extra flavor, try different seasonings depending on how you plan to use the onions.

How to Make Air Fryer Crispy Onions recipe :
Step 1
Kick things off by peeling the onions and slicing them very thin. Try to keep the slices the same thickness so they cook evenly. A sharp knife or a mandoline slicer works best for this step. Thin slices are the key to extra crispiness.
Step 2
As soon as finished place the sliced onions into a large bowl. Drizzle them with the oil and toss gently so every slice gets a light coating. Sprinkle the cornstarch, salt, pepper, and any extra seasonings over the onions. Toss again until the onions are evenly coated. This coating helps the onions crisp up instead of steaming.

Step 3
While waiting preheat your air fryer to 350°F (180°C). Spread the onions in the air fryer basket in a thin layer. Try not to overcrowd them. If needed, cook in batches so the air can move freely around the onions.
Step 4
Transition to cook the onions for 8 to 12 minutes, shaking the basket every 3 to 4 minutes. This step is very important because it helps the onions cook evenly and prevents burning. Keep an eye on them during the last few minutes since they can turn from golden to burnt quickly.

Step 5
For the finishing step once the onions are golden brown and crispy, remove them from the air fryer and let them cool for a few minutes. They will become even crispier as they cool.
