Ingredients You Need
- Sweet Potatoes – this recipe uses sweet potatoes that are peeled. If you want to keep the skin on, make sure to wash and scrub the potatoes thoroughly because dirt can easily become lodged in the skin. You could also use yams for this recipe, if you want.
- Cooking spray or olive oil – A little bit of oil will help the potatoes get crispy and prevent them from sticking to the air fryer basket. You can either spray them with your favorite cooking oil, or toss them in a bit of olive oil before putting them in the basket.
- Salt & pepper – Adjust the amount used to fit your tastes. You could also use seasoned salt or your favorite salt blend instead.
What Oil & Oil Sprayer is Best for the Air Fryer?
The biggest issue most air fryer lovers face is finding the right oil and oil sprayer to use on food cooked in the air fryer. A fine mist of oil will help the entire piece of food crisp evenly, so it’s very important.
My personal preference is to use canola oil, extra virgin olive oil, or avocado oil. I use both a refillable spray bottle like the Evo one pictured below and non-propellant extra virgin olive oil, which has not harmful aerosols or chemicals.
How to Make Air Fryer Sweet Potato Cubes
Peel the sweet potatoes. Rinse them with cold water to remove any dirt and debris.
Slice and cube the potatoes into ½” pieces. You can make them larger than this, if you like, but the cook time will vary based on the size of the cubes.
Spray the potato cubes with cooking spray (or toss with a small amount of olive oil) and season with salt & pepper. You can season the potatoes at this point with any seasoning or salt you like. Get creative with the seasonings for fun.
Place the sweet potato in the air fryer and cook at 400°F for approximately 12-14 minutes, shaking the basket at the halfway mark, until crispy and tender. Season with additional salt as desired before serving.
Why Use an Air Fryer
An air fryer is an incredibly easy way to cook just about anything. You place the food in a fryer-style basket and hot air rapidly circulates all around the food, making the food crisp – much like deep-frying, but without the oil. You can cook anything you’d make in the oven.

Questions About the Recipe
How can I make the sweet potato cubes in the oven?
To roast them in the oven, follow the same steps as for the air fryer, but place the cubed sweet potatoes into an oven that has been preheated at 425°F. Bake them for 30 minutes, shaking the baking pan halfway through.
Should I boil or soak the potatoes before adding them into the air fryer?
No. This recipe is meant to be super simple, so there is no need to boil or soak the potatoes ahead of time.
Can I use frozen sweet potato chunks in this recipe?
Absolutely. The steps are the same for frozen and fresh sweet potato cubes, but you should add a bit more oil to the frozen potatoes. Place them in the air fryer for about 15 minutes at 400°F and they should be good to go!
Tips
- To cube the sweet potatoes, it is best to use a sharp knife. Sweet potatoes can be difficult to cut, so be careful.
- Serve the sweet potatoes fresh, as they lose their crunchy texture quickly.
- Adjust the cooking time to make the sweet potato cubes more or less crispy – depending on your preference.
Storing & Reheating Suggestions
If you end up with some left overs, you can store the air fried sweet potato cubes in an airtight container and keep them refrigerated for up to 4 days. To reheat the potatoes, just air fry them again for 3-5 minutes at 400°F.
You can also freeze sweet potato cubes before or after they’ve been air fried. This is a great way to do meal prep, because all you’d need to do is take the prepared cubes from the freezer and put them in the air fryer to be reheated. They can last in the freezer for many months.
