These Air Fryer Sweet Potato Fries are golden and crispy on the outside, tender and creamy inside, and need only a small amount of oil. They’re a quick, versatile side that finishes much faster than oven-baked fries and pairs perfectly with burgers, sandwiches, bowls, grilled proteins, and a variety of dipping sauces.
Sweet potatoes are a pantry favorite for many households. They work well roasted, mashed, or turned into fries. Because sweet potatoes contain more natural sugars and moisture than russets, they can be trickier to crisp, but an air fryer helps by circulating hot air to evaporate moisture and create caramelized, slightly crispy edges without deep frying.
Success with air fryer sweet potato fries comes down to a few simple techniques: slice the fries uniformly, dry them well, and avoid overcrowding the basket. These small steps produce fries that are crisp at the edges and soft in the center.
Why you’ll love this recipe
- Crispy edges and tender, creamy centers with natural caramelized sweet potato flavor.
- Uses far less oil than deep frying while still delivering satisfying texture.
- Fast to prepare—ready in roughly 15 minutes of cook time.
- Ideal for weeknight dinners and easily customized with different seasonings.
Recipe ingredients
- Sweet potatoes — Choose orange varieties like Jewel or Garnet for a balance of sweetness and texture. Japanese or Hannah types tend to be denser and starchier.
- Oil — A neutral, high-smoke-point oil such as avocado oil works best for browning and crisping.
- Spices — The recipe uses garlic powder and smoked paprika, but you can swap in thyme, rosemary, Italian seasoning, or your favorite spice blend.
- Cornstarch (optional) — Tossing the fries with 1–2 teaspoons of cornstarch before air frying helps absorb surface moisture and encourages browning for a crisper exterior.

How to make sweet potato fries in the air fryer
Because sweet potatoes release more moisture than russets, it’s important to allow space between pieces so hot air can circulate. This prevents steaming and helps the fries crisp.
Pro tip: Cut the fries into uniform 1/4″ thickness and cook them in a single layer with some space between each piece for even browning.
- Peel (optional) and cut the sweet potatoes into uniform 1/4″ fries, then pat them very dry to remove surface moisture.
- Mix the oil and seasonings in a bowl.
- Toss the cut sweet potatoes with the oil and spice mixture until evenly coated. If using cornstarch, add it now and toss to coat.
- Arrange the fries in a single layer in the air fryer basket with a little space between pieces. Air fry at 390°F (200°C) for 13–15 minutes, shaking or flipping about halfway through, until the edges are browned and the centers are tender.
Tips for crispy sweet potato fries
- Dry the fries thoroughly after cutting to remove excess surface moisture.
- Avoid overcrowding the basket; work in batches if needed.
- Cook in a single layer for the best, even results.
- Shake or flip the fries halfway through the cook time for consistent browning.
- For extra crunch, toss fries in 1–2 tablespoons of cornstarch before oiling and seasoning.
- Serve immediately—the fries will soften as they cool.
Recipe FAQs
Compared with deep-fried fries, air fryer sweet potato fries use much less oil while still delivering a satisfying crisp and caramelized taste.
Soaking is optional. Sweet potatoes have less starch than russets, so soaking won’t change the texture as dramatically, but it can remove some surface starch. If you soak, be sure to dry the pieces thoroughly before cooking.
Overcrowding the basket or not drying the potatoes well enough will cause steaming instead of crisping. Cook in a single layer and leave a little gap between pieces to avoid sogginess.
Serving suggestions
These fries complement many meals—serve them alongside burgers, sandwiches, grain bowls, or grilled fish and meats. They’re also great as an appetizer with dipping sauces.
- Try them with Greek yogurt ranch, green goddess dressing, ketchup, or a simple fry sauce.
- Serve as a side with grilled burgers or turkey burgers.
- Pair with pulled chicken, pulled pork, or a grilled salmon for a complete meal.
Recipe notes
- Fries soften as they cool, so they’re best enjoyed immediately after cooking.
- Store leftovers in an airtight container for up to 5 days. Reheat in the air fryer for a few minutes to restore crispness.
- Because sweet potatoes contain more moisture than russets, they won’t become as dry and crackly as classic French fries, but they will be deliciously caramelized and tender.
