Not turn the food or shake the basket

The good news is that you don't have to arrange your French fries on the bottom of the basket in a single layer. Pieces of food can still contact each other even if the container is overfilled. Ninja says it's okay to stuff a bunch of fries into the air fryer's basket. To ensure that all or the majority of the fries have adequate touch with the flowing air, it is important to shake the basket regularly while it is cooking.

Even so, it's crucial to avoid packing the basket too full because if there are too many fries, no amount of shaking will get them all crispy. Additionally, even when cooking items in a single layer, such as a row of chicken strips, you must open the basket halfway through cooking in order to turn them over. This promotes even cooking and guarantees that all of the food is uniformly golden in color.
