These Air Fryer Sweet Potato Fries deliver crispy, caramelized edges and a tender interior using only a small amount of oil. They’re a quick, reliable side that cooks faster than oven-baked fries and pairs beautifully with burgers, sandwiches, bowls, and grilled proteins.
Sweet potatoes are a staple in many kitchens because they’re versatile and full of flavor. While mashed or roasted sweet potatoes are classics, fries are a favorite for their satisfying texture and convenience. Because sweet potatoes hold more moisture and natural sugar than russets, achieving crispiness can be challenging—this is where the air fryer shines. The rapid circulating heat evaporates surface moisture and encourages caramelization, producing fries that are crisp on the edges and soft in the center without deep frying.

Recipe ingredients
- Sweet potatoes — Orange-fleshed varieties (Jewel, Garnet) work best for a balance of moisture and sweetness. Starchier types (Japanese, Hannah) will be denser.
- Neutral oil — Avocado, canola, or another high-smoke-point oil for good browning.
- Seasonings — Garlic powder and smoked paprika are suggested; swap or add herbs like thyme, rosemary, or Italian seasoning to taste.
- Cornstarch (optional) — A light toss with 1–2 teaspoons helps absorb surface moisture and promotes crispiness.

How to make sweet potato fries in air fryer
Because sweet potatoes release more moisture than russet potatoes, it’s important to give the fries room in the basket so hot air can circulate. Even slices, thorough drying, and single-layer cooking are key steps.
Pro tip: Cut fries to a uniform 1/4″ thickness and air fry them in a single layer with space between pieces for the best texture.
- Peel the sweet potatoes and cut into uniform 1/4″ sticks. Pat thoroughly dry to remove surface moisture.
- Toss the fries with oil and spices until evenly coated. If using cornstarch, dust lightly and toss to coat.
- Arrange the fries in a single layer in the air fryer basket with a bit of space between pieces.
- Air fry at 390°F (200°C) for about 13–15 minutes, shaking or flipping halfway through, until edges are browned and centers are tender. Serve immediately.
Tips for crispy sweet potato fries
- Dry the cut fries thoroughly before tossing with oil and seasoning.
- Avoid overcrowding the basket — work in batches if needed.
- Cook in a single layer for the most even crisping.
- Shake or flip halfway through the cook time for even browning.
- For extra crunch, toss in 1–2 teaspoons of cornstarch before adding oil and seasonings.
- Serve immediately. Fries soften as they cool, so they’re best enjoyed fresh from the air fryer.
Recipe FAQs
Compared to deep frying, air fryer sweet potato fries use much less oil while still offering a crispy texture and caramelized flavor, making them a lighter alternative.
Do I need to soak sweet potatoes before air frying?
Soaking is optional. Sweet potatoes have less starch than russets, so soaking does not make as much difference. If you do soak, dry thoroughly before cooking.
Why are my fries soggy?
Overcrowding is the main culprit. Give each fry a little space so hot air can circulate, and don’t skip drying the pieces first.
Serving suggestions
These fries go well with burgers, sandwiches, grain bowls, grilled meats, and a variety of dips.
- Serve with ketchup, Greek yogurt ranch, green goddess dressing, or your favorite dipping sauce.
- Pair with grilled burgers, turkey burgers, or BBQ pulled chicken for a satisfying meal.
- Pair with fish, pork chops, or roasted vegetables for a complete dinner.
Recipe notes
- Sweet potato fries will soften as they cool, so serve quickly for the best texture.
- Store leftovers in an airtight container for up to 5 days. Reheat in the air fryer for a few minutes to refresh crispness.
- Because sweet potatoes contain more moisture than russets, they won’t get as dry and crunchy as traditional French fries, but the air fryer helps get them very close.
