Sweet Potato in Ninja Foodi Air Fryer
You can make them in a Cosori, Instant Pot air fryer, or Ninja Foodi. For the latter machine you will use the lid that is attached with the air crisp button. The larger the basket the more you can make at once as you don’t want them to overlap at all.
Tips: My Favorite models are the Cosori or making Ninja Foodi recipes with the lid that is attached.

This is what ours looked like. Honestly we hadn’t really made sweet potatoes in a long time, and never in the air fryer. Before, the best way to make baked potatoes without foil was in the oven. Not. Anymore!

Ingredient Notes
You will want to start with a few medium sized sweet potatoes. Look at the signs in the produce section because yams look similar but are different. Timing for large varieties would take longer. Just use a knife near the end to test. If it slides in easily it is done, tough to push thru means it needs more time.
Olive oil or avocado oil should coat the outsides of the skin liberally. Like so much that it dripping off just a bit. This will keep it from burning and also crisp to a golden brown as well.
Coarse sea salt is needed if you want to add some to the skins to make them salty/sweet in flavor. Keep in mind that the skins are thicker than russets but they are edible.
How Long to Cook Whole Sweet Potatoes in Air Fryer
It really is no different than if you want to make air fryer baked potatoes, depending on the size. Both have the same type of skin, this is a bit thicker but doesn’t make a huge difference in cook time. Typically you aren’t going to want to eat the outsides of these, that is the main difference. Set aside 35 minutes in general to get it done.
With that said I wouldn’t bother salting the skins like I do with russets to give it flavor. The inside is where it’s at with these, fluffy and tender ready for some butter, cinnamon and sugar.

FAQ
The skin of a yam looks kind of like tree bark, while a sweet potato is more of a red brown color. Real yams are entirely different root vegetables that are more like yucca.
They have a bumpy, tough, brown skin. They’re more starchy without a sweet flesh. Honestly, look at the labels in your produce department or you’ll just be confused!
When done you should stuff with; Butter, Cinnamon and sugar mixture, Maple syrup or honey (real / pure is always better) or you can use agave nectar instead to drizzle inside. For a healthier savory choice, some love our 5 ingredient chili inside!
Yes, you can eat sweet potato skin and it’s actually good for you. The skin is packed with fiber, along with extra nutrients like antioxidants, vitamins, and minerals that you don’t get as much of from just the flesh. As long as you wash the sweet potato well to remove dirt or residue, the skin is completely safe to eat whether the potato is baked, roasted, or even mashed. Some people prefer the texture more when it’s cooked until slightly crispy, but it’s really just a matter of taste.
You need to coat the outside liberally with olive oil at the beginning so it doesn’t dry out. To go further, you can spray more on midway thru to ensure that they do get crispy but don’t dry out.
Yes you do. Make sure they are cooled to room temperature and store in a freezer bag free from air or wrapped in tinfoil. It is best to reheat within 24 hours but can be kept up to 3 days.

What is the Best Way to Cook Whole Sweet Potatoes Crispy?
This is it my friends!! You have got to air fry them to get the best results. The texture is like no other, very similar to what you would get at a restaurant. Using hot air, in a single layer with some olive oil on the outside you will achieve the same crispy outcome as Ninja foodi french fries or our popular Sweet Potato Latkes but in a larger form.
What can you make with leftovers?
Of course if it is around the holidays you can use this as a starter to a batch of sweet potato casserole with canned yams but use the insides mashed instead. Load it up with butter, candied pecans and mini marshmallows melted on top for a tasty side dish.
