air fryer sweet potato cubes are my weeknight superpower. They’re quick, crispy, and somehow feel like a treat even on a busy Tuesday. If you’re like me and love recipes that taste amazing without a sink full of dishes, you’re in the right place. I’ve been making these on repeat, and they’re a total crowd-pleaser. Oh, and if you’re into easy flavor bombs to round out dinner, you’ll love this fun twist I tried recently: a Buona Beef Tuna Genovese copycat recipe. Now, let’s bring crispy comfort to your plate fast.
Which Sweet Potato to Use for Roasting?
Sweet potatoes vary more than you might think, and choosing the right kind makes a big difference in how your air fryer sweet potato cubes turn out. Look for orange-fleshed varieties like Beauregard, Jewel, or Garnet. They’re naturally sweet, roast up tender inside, and caramelize beautifully on the edges. Purple sweet potatoes are tasty but a bit drier, and the white ones come out more mild. For best results, grab medium-sized sweet potatoes that feel heavy for their size with smooth, unwrinkled skin.
If you see stringy ends or soft spots, skip those. The goal is even texture from end to end so your cubes cook at the same rate. I also try to keep them at room temp for 15 minutes before cutting. Chilled sweet potatoes can be stubborn and hard to slice. A quick rinse and a good scrub helps if you keep the skins on. I do it half the time because the skins get a slight crisp and add a little earthy flavor.
Storage tip: Keep sweet potatoes in a cool, dark spot. Not the fridge. Cold can mess with their texture and taste. A pantry or cabinet is perfect.
Short answer: Orange-flesh sweet potatoes are your MVPs for flavor, color, and even roasting. They’ll deliver that creamy inside and crunchy outside we’re after.
How to Cut Sweet Potatoes for Roasting?
The size of your cubes is more important than you’d think. Aim for about 3/4-inch cubes. Smaller cubes crisp faster but can dry out if you go too tiny; larger ones need more time and may end up soft. I keep them as even as possible so every piece hits crispy and tender at the same time.
Knife Safety and Prep
Use a stable cutting board and a sharp chef’s knife. Slice a thin piece off one side to make a flat base, then cut planks, then sticks, then cubes. You can peel or not peel. If I’m feeling rustic, I leave the skin on. It crisps nicely and adds texture. If you want extra uniform crisp, peeling gives a smoother surface for browning.
Size Matters for Crispiness
Consistency is everything. Even cubes mean even cooking. If you mix tiny bits with big chunks, the small ones may scorch while the big ones are still firm. Remember, air fryers do best with space, so keep your cubes similar in size and don’t overfill the basket.
If your potatoes are super dry, a quick rinse and pat dry helps remove surface starch and encourages better browning. Just don’t soak them for long. Sweet potatoes don’t need it the way regular potatoes sometimes do.
How to Cook Sweet Potato Cubes in the Air Fryer
Here’s the simple path to magic: a hot air fryer, a little oil, and the right seasoning. I like avocado or olive oil and a spice blend that leans savory with a hint of sweet. If you feel like diving into more crispy comfort, you might also enjoy these healthy sweet potato hash browns for breakfast or brinner.
What You’ll Need
- 2 medium sweet potatoes, about 1.5 pounds total
- 1 to 1.5 tablespoons oil
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1 teaspoon paprika or smoked paprika
- 1/2 teaspoon garlic powder
- Optional: 1/2 teaspoon chili powder, pinch of cinnamon, or 1 teaspoon brown sugar for sweet heat
Directions
- Preheat the air fryer to 400°F for 3 to 5 minutes. A hot basket helps instant browning.
- Cut into 3/4-inch cubes. Pat dry if needed.
- Toss with oil and spices in a large bowl until every piece is coated.
- Load the basket in a single layer. A little space between cubes is key for crisp edges.
- Cook at 400°F for 12 to 16 minutes, shaking the basket halfway. Start checking at 12 minutes. You want golden edges and a fork-tender center.
- Finish with a tiny pinch of salt while hot. Taste and adjust.
Batch size matters. If your basket is small, cook in two rounds. You’ll get more crunch that way. For extra char, let the cubes sit undisturbed for the first 6 minutes, then shake. If your air fryer tends to run cool, add 2 minutes. If it runs hot, check at 10 minutes.

Recipe Tips and Expert Tips
Flavor Variations
Sweet potatoes play well with tons of flavors. Try a ranch seasoning blend, curry powder and a squeeze of lime, or maple and cinnamon with a pinch of cayenne. If you love smoke, add a tiny splash of liquid smoke to your oil before tossing. If you’ve never cooked with it, this easy primer on using smoky flavors with spuds is helpful: liquid smoke russet potatoes.
Want extra crunch? Dust the cubes with 1 teaspoon of cornstarch before the oil. It creates a thin surface that crisps beautifully. Go light, though. Too much makes them chalky.
Make-Ahead and Storage
Meal prep friendly? Absolutely. Cube your sweet potatoes up to 24 hours ahead and store in water in the fridge, then drain and pat dry before cooking. Cooked leftovers keep 3 to 4 days in the fridge. Reheat in the air fryer at 375°F for 3 to 5 minutes to bring back the crunch. Microwaving works in a pinch but softens them a bit.
If you’re cooking for a crowd, season in a big bowl and shake gently with your hands. It’s oddly satisfying and coats everything more evenly than tossing with a spoon. For a little glaze, drizzle with hot honey right after cooking. That sweet-spicy note with the smoky paprika is so good.
What to Serve With Air Fryer Sweet Potato Cubes
These little crispy bites make almost everything better. I serve them with grilled chicken, turkey burgers, or a simple bowl of scrambled eggs. They’re awesome as a salad topper too. Toss them with arugula, goat cheese, and a lemony dressing. For game night, I’ll pair a tray with a garlicky dip, a chipotle mayo, or a maple mustard sauce. If you want to go cozy all the way, a bowl of potato kale soup and a heap of these cubes on the side is cold-weather gold.
Serving ideas:
- With eggs and avocado for a quick brunch
- As a base for bowls: quinoa, black beans, corn, and salsa
- Alongside grilled salmon or shrimp with lemon
- On tacos with cabbage slaw and lime crema
- With a balsamic glaze and toasted pecans for a sweet-savory twist
And if cookouts are your thing, they work beautifully next to pulled pork or rotisserie chicken. For picnics, I sometimes mix a handful into a chilled salad like this classic-style deviled egg potato salad for extra color and sweetness.
Common Questions
Do I have to peel sweet potatoes?
Nope. Peel if you prefer a cleaner look and smoother bite. Leave the skin on for more texture and a little extra fiber. Both ways work.
How do I keep them from getting soggy?
Keep the cubes the same size, avoid overcrowding, and cook hot. Preheating helps a lot. If your basket is packed, cook in batches.
What if my air fryer doesn’t have a 400°F setting?
Use 390°F and add 2 to 3 minutes. Shake halfway and check for browning at the edges.
Can I make them oil-free?
Yes. They’ll still cook, but the edges won’t crisp as much. Consider a quick spritz of nonstick spray if you want a bit more color.
Can I use frozen sweet potato cubes?
Yes, but don’t thaw. Cook straight from frozen at 400°F, shaking a couple of times, and add a few extra minutes until crisp and hot.
