How To Make Air Fryer Sweet Potato Fries
A step-by-step guide to the best, crispiest homemade fries.
- Cut and Prep the Potatoes: Cut the sweet potatoes into uniform planks about 1/2-inch thick and 4 to 5 inches long. If the potatoes are moist after cutting, pat them completely dry with a paper towel. Place them in a large mixing bowl.
- Season the Fries: In a small bowl, mix together the salt, cumin, cayenne pepper, and black pepper. Drizzle the olive oil over the sweet potatoes and toss to coat. Sprinkle the spice mixture all over and toss again until the fries are evenly coated.
- First Air Fry: Place half of the seasoned sweet potato fries in a single layer in your air fryer basket, leaving a little space between each fry. Cook at 380°F for 7 minutes.
- Second Air Fry: After 7 minutes, toss the fries in the basket and space them out again. Return to the air fryer and cook for another 7 minutes. Transfer the cooked fries to a plate and repeat the process with the remaining half of the uncooked fries.
- Make the Dipping Sauce: While the fries cook, make the creamy honey mustard. In a small bowl, whisk together the mayonnaise, Dijon mustard, and honey until smooth.
- Final Crisp and Serve: Once all the fries have been cooked, transfer all of them back into the air fryer basket together. Cook at 400°F for 3 to 5 minutes, until all the fries are re-warmed and extra crispy. Season with more salt to taste and serve immediately with the dipping sauce.

Recipe Tips
For the crispiest, most flavorful air fryer sweet potato fries.
- How to get the fries extra crispy? There are three secrets in this recipe. First, don’t overcrowd the air fryer basket; cook in a single layer. Second, pat the cut potatoes completely dry to remove excess moisture. Third, the final 3-5 minute cook at a higher temperature (400°F) is a brilliant trick to re-heat and give all the fries a final, perfect crisp before serving.
- What’s the best way to cut sweet potato fries? The key is uniformity. Cutting the fries into a similar size and thickness ensures that they all cook evenly and are perfectly done at the same time.
- Can I make these in the oven? Yes. Toss the fries as directed and spread them in a single layer on a large, parchment-lined baking sheet. Roast in a preheated 425°F oven for 20-25 minutes, flipping halfway through, until crispy and golden.
- Can I use a different seasoning blend? Absolutely! Smoked paprika, garlic powder, and a pinch of brown sugar would be a delicious sweet and smoky alternative to the cumin and cayenne.

FAQs
While soaking is a common trick for regular potatoes to remove excess starch and achieve a crispier result, it’s not as necessary for sweet potatoes. Simply patting them very dry is sufficient to help them crisp up nicely in the air fryer.
The most common culprit for soggy fries is overcrowding the air fryer basket. When the fries are piled on top of each other, they steam instead of “frying.” Cooking them in a single layer with space for the hot air to circulate is essential for crispiness.
Of course! The creamy honey mustard is delicious, but these fries are also fantastic with a spicy chipotle aioli, a simple garlic mayonnaise, or even just classic ketchup.
