Step 3: Pour the mixture into your air fryer basket. It’s okay if the pieces overlap. Generally, you’ll be filling the basket at least halfway up, depending on the size of your basket. It’s okay, because you’ll be stirring it twice during cooking.

How To Store Leftovers

To maintain freshness and flavor, store any leftover peppers and onions in an airtight container with a tight-fitting lid to keep the aroma from permeating other things in your refrigerator. If you have a large batch leftover, consider separating them into individual portions before storing them.
