My Favorite Way to Air Fry Sweet Potato Cubes
My air fryer sweet potato cubes were created to make a quick side dish in the fall that my kids would eat. Now, it’s become a go-to side for my family because of how versatile it is to pair with most of my dinner recipes. And, we eat it all year round and not just in the fall!
While I love baked sweet potatoes in the air fryer, they take a good 40 minutes to cook. That’s just not feasible for a weeknight dinner, so I created this recipe to be easy, quick, and delicious.
My recipe is designed to include only ingredients that are typically in my pantry, so I can easily use up any extra sweet potatoes. I love to include a little brown sugar to add to their natural sweetness, and my kids absolutely love them!

Ingredients for Air Fried Sweet Potato Cubes
- Sweet potatoes – I use just 1 large or 2 medium sized fresh sweet potatoes

- Salt
- Dried parsley – optional, but I love the way it looks on the sweet potatoes

STEP THREE: Transfer them to an air fryer basket or tray and cook for 8-10 minutes, rotating the sweet potatoes halfway through cooking. Sprinkle with fresh parsley as a garnish and serve immediately!
Tips For the Best Roasted Sweet Potatoes in the Air Fryer
- Try to cut the sweet potatoes into similarly-sized cubes to make sure they cook evenly.
- Preheat the air fryer before cooking the sweet potatoes. I find preheating an air fryer to be the best way to get a crispy outside on this recipe and other recipes.
- Cook them in a single layer so the air fryer has plenty of room to circulate the hot air and crisp up all sides evenly. I cook in batches when I have more than my air fryer can handle cooking at once.
- Rotate the sweet potatoes halfway through air frying for even browning on all sides.
- Store leftovers in an airtight container in the refrigerator for up to 4 days. I reheat them in the air fryer at 360 degrees for about 3 to 4 minutes.
Substitutions and Variations to Air Fry Sweet Potatoes
- Make it taste savory by omitting the brown sugar and adding onion powder and garlic powder. I do this from time to time to switch up the flavors.
- Toss with cinnamon to add a hint of warm spice. I’ve even added some honey and maple syrup on them for a very sweet option.
- Sprinkle with Parmesan cheese near the end of the cooking time for a cheesy twist.
- Add fresh herbs like rosemary or thyme for a boost of flavor. I like to sprinkle them on just before serving for a pop of color!
- Toss red pepper flakes or chili powder in with the seasoning mixture to add a little heat. This is my favorite when I’m in the mood for a spicy kick!
What to Serve With Sweet Potato Cubes in the Air Fryer
I love pairing these with a simple protein like air fryer chicken tenders, pork loin in the air fryer, air fryer boneless pork chops, or air fryer chicken legs.
If I want to make a main dish outside the air fryer, I usually choose my chicken spaghetti with Rotel, London broil, or steak fajitas. Honestly, they make the perfect side dish to most dinners.
Air Fryer Sweet Potato Cubes FAQs
How Long To Air Fry Sweet Potato Cubes
I find sweet potato cubes take just 8 to 10 minutes to cook in a preheated air fryer at 400 degrees F. They are done cooking when they are golden brown on the outside and can be easily pierced with a fork.
How To Make Air Fryer Sweet Potato Cubes From Frozen
I find air frying frozen sweet potatoes don’t get as crispy, but they still taste delicious. I just use this same recipe, but increase the cooking time to 14 minutes.
Should I Soak My Sweet Potatoes Before Air Frying?
No, my recipe does not require any soaking of the sweet potatoes before they are air fried. I find they get just as crispy as I like them without needing to do the extra step.
Why Are My Sweet Potatoes Not Crispy In The Air Fryer?
The first time I made this recipe my sweet potatoes did not get crispy because I had too many in the air fryer at once. They should sit in one single layer without touching as best as possible for the crispiest results. I also find that sweet potatoes will also get crispier when they are dried fully before adding the oil.
