How to Make Air Fryer Sweet Potato Cubes?

Sweet potatoes should be peeled. Remove any dirt and debris by giving them a cold water rinse.

The potatoes should be cut into 12″ cubes. If you’d like, you may make them bigger than this, but the size of the cubes will affect how long they need to cook.

Cooking spray or a tiny quantity of olive oil can be tossed with the potato cubes after seasoning with salt and pepper. At this stage, you can salt or season the potatoes anyway you prefer. For fun, experiment with different seasonings.

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. Before serving, season with extra salt as required.

Don’t scrimp on the spices and ingredients.

1 tablespoon of olive oil is required for this recipe for air-fried sweet potato cubes. Because they don’t need oil, air fryers are quite popular.

I tried this recipe both ways: with and without the tablespoon of olive oil. These are my conclusions.

The interior of the batch that had olive oil grew softer and more delicate. They crisped up a little more slowly than usual, but they didn’t burn.

Before air frying, nonstick spray was applied to the batch that did not use olive oil. They became crispier considerably faster, and some of them started to turn black. They were also considerably tougher and did not internalize softness.

Finally, I strongly advise applying oil. You may make this dish with or without it, however the batch made with olive oil was significantly superior.


Sweet potato cubes from an air fryer should be hot and fresh. They taste fantastic straight from the air fryer.

Serve with chicken, steak, or hamburgers.

If you have any leftovers, you can preserve the air-fried sweet potato cubes in the refrigerator for up to 4 days by storing them in an airtight container. Simply air fried the potatoes one more for three to five minutes at 400°F to reheat them.

Additionally, sweet potato cubes can be frozen either before or after air frying. This is a terrific method for dinner preparation because all you’d have to do is reheat the prepared cubes in the air fryer after removing them from the freezer. They can last for several months in the freezer.


How can I make the sweet potato cubes in the oven?

Follow the same procedures as for air frying them to roast them in the oven, but instead put the cubed sweet potatoes into a 425°F-preheated oven. Shake the baking pan halfway during the 30-minute baking period.

No. There is no need to boil or soak the potatoes in advance because this recipe is supposed to be extremely straightforward.

Can I use frozen sweet potato chunks in this recipe?

Completely. Both frozen and fresh sweet potato cubes may be prepared in the same ways, although the frozen potatoes require a little more oil. They should be ready to eat after 15 minutes at 400°F in the air fryer.
