INGREDIENTS 

sweet potatoes, olive oil, garlic powder, pepper, an air fryer basket, and vegetable peeler on a white table.

Sweet Potato – choose two to three medium sweet potatoes that are bright in color and firm with smooth skin. If you can’t find sweet potatoes, garnet yams can also work in a pinch.

Olive Oil – extra light olive oil is best when using an air fryer because it has a high smoke point. Alternatively, you can use avocado oil or grapeseed oil.

Black Pepper – ground black pepper adds a fragrant punch to the sweetness of the potatoes. For the best flavor, use freshly ground pepper.

Garlic Powder – use finely ground garlic powder. You can alternatively use garlic granules if you have them on hand.

HOW TO MAKE AIR FRYER SWEET POTATO CUBES

STEP 1: Rinse the sweet potatoes under cold running water, then pat them dry with a towel. Remove the skin by peeling the potatoes with a vegetable peeler.

STEP 4: Preheat the air fryer to 400º F.

STEP 5: Once the air fryer is preheated, add the seasoned potatoes to the prepared air fryer basket in a single layer, making sure not to overlap any of the cubes for even cooking.

STEP 6: Air fry the potatoes at 400 degrees F for 15-20 minutes, shake the basket halfway through the cooking time, until crispy.

TIPS

  • Preheat the air fryer-Before you prepare the potatoes, preheat your air fryer. This will help cook the potatoes faster and make them crispier because the air fryer will already be at the needed temperature. If your air fryer model does not have a preheat option, just leave the basket empty and air fry at 400 degrees F for 3 minutes.
  • Don’t overcrowd the air fryer- If you cannot lay the potato cubes in a single layer in the air fryer basket without overlapping them, cook in several batches. 
  • Flip halfway-Flip the potatoes halfway through the recommended cooking time so the cubes cook evenly on all sides. It is also a good opportunity to check on the potatoes and gauge if you need to reduce or increase the amount of cooking time.
  • Adjust the temperature and cooking time as needed. This recipe was made using the Cosori Air Fryer. If you’re using a different air fryer, you may need to adjust your cooking time accordingly.

VARIATIONS

  • For savory sweet potatoes, sprinkle the sweet potatoes with chili powder, onion powder, and paprika. Or, dust with ground cinnamon and a tablespoon of maple syrup before serving for a sweet and warming flavor profile.
  • For a little extra heat, sprinkle sweet potatoes with a pinch of cayenne pepper and an extra pinch of salt.

Notes

It’s important to preheat for this recipe so the sweet potato cubes come out crispy.  
If you cannot lay the potato cubes in a single layer in the air fryer basket without overlapping them, cook in several batches. Crowding the air fryer will prohibit the potatoes from cooking evenly and getting the delicious crisp edges!  
The best part about this sweet potato air fryer recipe is the crispy edges of the potato cubes. The potatoes will soften as they cool, so serve them immediately for the best texture.
