Key Ingredients
Below is a list of ingredients needed for this recipe. Follow our tips on each ingredient for the best results.
- Sweet Potatoes- Use fresh sweet potatoes for the best results.
- Avocado oil or similar - I found while testing recipes in my air fryer that olive oil tends to leave a buildup. Its smoke point is also 350° F, so be careful when using it not to cook at a higher temperature than that.
- Salt, pepper, and cumin - I tested this recipe over and over to get the perfect blend of seasonings for the best flavor.
How to Make Sweet Potato Cubes in the Air Fryer
- Preheat air fryer to 450°F. Peel roughly one pound of sweet potatoes. If you're off by an ounce or 2, it's fine! If the potatoes are giant, this will be about 1 potato; if they're small, it could be as many as 3-4. Medium, about
- You get the idea. Cut the sweet potato(s) into ½" cubes and place in a medium/ small bowl. Add the oil and toss or mix with a spatula to evenly coat the sweet potatoes. You don't need a lot of oil to make these, but you do need some, or the outsides will burn. If you like the outsides extra crispy and bubbly, double the oil amount.
- Add the spices, and give them another toss or mix with a spatula to evenly coat.
- Place in the air fryer. Cook about 10 minutes total, shaking the basket around minute 5-6. Not all air fryers are created equal (we have the NINJA XL that is also a grill), so check again at 8 minutes. The outside of the potatoes will turn dark and a little bubbly in places when they're done.
Top Tips
If using frozen sweet potato cubes, use them frozen and make them the same as directed, just cook an additional 2-5 minutes.
For sweet potato lengths, simply cut into strips no bigger than ½" wide, and cook with the same method, but plan on a slightly longer cook time.
Feel free to omit the cumin, half the salt, and add 1 teaspoon cinnamon/ sugar mixture for a fun variation.

How to Store Sweet Potato Cubes
These store great in the refrigerator in an airtight container for up to 5 days. I enjoy them cold. To serve hot, place in a preheated air fryer (again to 450*) for 2-3 minutes.
