Add a single layer of spinach leaves to the air fryer basket. Air fry at 400 F for 3-5 minutes, until crispy.TIP - You will have to work in batches to achieve crispy spinach. Adding too many spinach leaves to the basket at once will not allow enough air to flow.
We suggest using Kosher salt for this recipe. However, it's very easy to use too much salt with spinach since it cooks down so much. The volume of spinach reduces significantly when it cooks. Start with a small amount of salt, taste it, then adjust to your liking.
There's a lot of room for customization when it comes to the seasoning you use, just like with regular chips. I've made these with Cajun seasoning and french fry seasoning as well. Feel free to play around.
Regular or baby spinach will work for this recipe. I would not recommend using frozen spinach as it's far too waterlogged to get that crispy airy texture we're aiming for. You want your raw spinach to be dry, so if you rinsed it off be sure to pat it dry with a paper towel.
