So, this Air Fryer Sweet Potato cubes recipe is the first of many I’ll be sharing over the coming months. Just in time for autumn!

“A good recipe, we cut back on the rosemary, as the grandkids not used to rosemary yet, but they ate every bite of these yummy sweet potatoes. This recipe is easy enough for kids to make it themselves with some minor overseeing by the adult.”

Air Fryer Sweet Potato Cubes

This sweet potato recipe is the perfect side dish for weeknight meals served with a protein like this Air Fryer Thin Pork Chops recipe, and as an added bonus, it’s healthy!

Air frying is one of the best ways to get a crispy exterior on your food without using a lot of oil. The hot air circulates around, crisping up your food.

This easy side dish recipe combines the natural sweetness of the sweet potatoes with savory spices and rosemary, once of my favorite herbs!

If you aren’t a rosemary fan, you can substitute thyme or sage. It will still be delicious.

These crispy air fryer sweet potatoes are a great side dish for weeknight dinners! It's one of the easiest ways to enjoy cubed sweet potatoes.


  • 2 pounds of sweet potatoes, peeled and cubed (less than 1 inch on all sides)
  • 1 tablespoon avocado oil
  • 1 tablespoon minced fresh rosemary
  • ¾ teaspoon garlic powder
  • ¼ cup freshly grated Parmesan cheese
  • ½ teaspoon salt
  • ¼ teaspoon black pepper


  1. Preheat your air fryer to 390 degrees Fahrenheit.
  2. Prepare the air fryer basket by spraying it with cooking spray.
  3. In a large mixing bowl, add sweet potato chunks, avocado oil, fresh rosemary, garlic powder, Parmesan cheese and salt and pepper. Toss to coat the sweet potatoes.
  4. Add sweet potato cubes to the air fryer basket. Air fry for 12-15 minutes, shaking the basket every 5 minutes.
  5. Once the sweet potato cubes are golden brown and easily pierced with a fork, they're done. Remove from the air fryer and serve warm.


Crispiness: You can spray the sweet potato cubes with extra oil in the last 5 minutes if they aren't crisping up.

As much as I love air fryers, the cook time can really vary from model to model! For this reason, I recommend checking your food every few minutes. When the sweet potatoes start to turn golden brown, they're close to being done.

Common modifications:

  • Spicy: To add a little heat, add ⅛ tsp or chili powder or cayenne pepper to the oil and spice mixture.
  • Sweet: To make a sweet version of this recipe, add 1 tablespoon or brown sugar or maple syrup to the oil and spice mixture.
