Crispy Air Fryer Roasted Sweet Potatoes Recipe

With the holidays right around the corner, I am excited about eating all of the sweet potato recipes like these healthy mashed sweet potatoes made with a secret ingredient. But, even though sweet potatoes are a fall staple, I really love cooking them year round. This is the perfect recipe to eat any time of year.

Sweet potatoes are a healthy side dish or snack, healthier than eating regular potatoes. They are packed full of beta-carotene, vitamin c and fiber. Did you know they can also help with vision, improve gut health, and may enhance brain function. They are yummy and good for you…sign me up!

In this delicious recipe, whole sweet potatoes get cut into small cubes, then coated in a thin layer of oil. Herbs are added to give a little more flavor and balance out the sweetness of the sweet potatoes.

These sweet potatoes don’t end up crunchy, but with a slight crispness (about as much as you can expect from a sweet potato).

And guess what, the smaller you cut the cubes, the more crisp they will cook up. Cutting the sweet potatoes up into bigger pieces will give you a softer texture. The choice is yours but I prefer them with a little crispness.

Air frying them is the perfect way to get a crispy exterior and a soft middle on those sweet potatoes. Just make sure not to crowd your basket and keep them in a single layer. If you are making more than a pound and a half of sweet potatoes, then you will want to cook in batches.

Another great thing about this air fryer recipe is that you can switch up the flavors if you like. Add some cinnamon and maple syrup to make them a little sweeter or change up the herbs for a whole new flavor. You can even make air fryer sweet potato fries.

The air fryer is a great way to bring out the natural sweetness of the sweet potatoes. It’s also the easiest way and the cooking time is so much shorter than if you roasted them in the oven.

Best Type of Sweet Potato to Use?

This recipe can be used for all the sweet potato colors like purple, orange, or white potatoes. I typically use the orange potatoes because it is most readily available in grocery stores.

The most common sweet potatoes I see are Jewel and Red Garnet, but others that are also great for roasting are Covington, Centennial, Beauregard, or Hernandez.

When buying sweet potatoes make sure to look them over. They should be firm, small to medium in size without any cuts or bruises and don’t get any that are going soft. I like using the ones that are long and thin because they are easier to cut through.

Recipe Tips

Clean sweet potatoes. Since sweet potatoes are grown in the ground, they end up pretty dirty. Rinse and scrub them well. Then dry them well with a paper towel or a clean towel.
Single layer. Make sure to keep the sweet potato pieces in a single layer or they won’t crisp up at all.
Similar size pieces. Make sure to try to keep the sweet potato chunks as uniform as possible so that they cook evenly.
Eat immediately. You want to enjoy these hot and right out of the air fryer because they start to get soft as they sit.
Check on food. Open the air fryer at any time to check on the potatoes to make sure they are not burning.
Different air fryers. All air fryers cook differently so this recipe may need more or less time. I use a Cosori 5.8 quart basket style air fryer.

Variations

Different flavors. Use different herbs and spices to season the sweet potatoes the way you like them.
Crispy sweet potatoes. For crispy air fryer sweet potatoes, cut them into 1/2 inch cubes.
Soft sweet potatoes. For softer sweet potatoes, cut cubes a little larger.
