Ingredient Notes

Sweet Potatoes: The best kind of sweet potatoes for this recipe are steamers that come in a microwavable bag. They are petite sweet potatoes that are triple washed and ready to cook, they are not precooked. Petite sweet potatoes are usually 4-5 ounces each. 

This small sweet potato is the perfect size for a healthy side dish. These can be found in the produce section of the grocery store with the potatoes, and is essential to the short cook time. 

If this type of sweet potato isn’t available look for small ones that are about the same size. If you can’t find small ones you will need to increase the cooking time until they are soft in the middle. 

Butter: Real butter, margarine or plant-based butter can be used as a topping on cooked sweet potatoes.

How to Make Air Fryer Baked Sweet Potatoes

1. If your sweet potatoes aren’t ready to cook then scrub them under cold water and dry thoroughly with paper towels.
2. Poke holes in each potato using a fork, a total of about a dozen times per potato. 
3. Place potatoes in the air fryer basket in a single layer leaving some space between them. 
4. Air fry on 400° for 18-20 minutes. Let cool until they can be handled. 
5. Slit each sweet potato lengthwise down the middle with a sharp knife, using your index finger and thumb of both hands pinch the end of the slit and push gently to pop open the potato. Be careful not to burn yourself because the potato is hot and steam will emit from it. 

Tips

• Since air fryer temperature may vary depending on what model you have check the sweet potatoes after about 16 or 17 minutes. 
• Dry sweet potatoes well after washing them. 
• Larger sweet potatoes will need to be cooked longer.

Variations

If you want crispy skin then brush each potato with a little bit of olive oil, canola oil or avocado oil.

You could also add some kosher salt or sea salt to the outside of the potato before air frying them.
