Side Dishes
This spiralized sweet potato fries recipe transforms humble sweet potatoes into crispy, golden spirals that rival any fast-food fry—without the grease. The secret lies in proper spiralizing and high-heat cooking, whether in an air fryer, oven, or stovetop.
I’ve perfected this method over years of testing, ensuring every batch delivers that satisfying crunch while keeping the inside tender and slightly sweet.
The magic starts with the right cut: spiralize the sweet potatoes thinly (about ⅛-inch thick) for even cooking, then pat them dry to prevent sogginess. Season generously with smoked paprika, garlic powder, and a drizzle of olive oil—these simple spices create a savory crust that stays crispy even after baking.
For extra flavor, toss in a pinch of cayenne or cinnamon for a sweet-spicy kick.
What you’ll end up with is a crispy-skinned, spiral-shaped side that’s perfect for snacking, game day, or pairing with dips like garlic aioli or spicy mayo.
The air fryer method delivers the crispiest results in just 12 minutes, while the oven version requires 20-25 minutes at 425°F. Each method guarantees a satisfying crunch that holds up even when stacked high on a platter.
These fries are naturally vegan, gluten-free, and packed with fiber and vitamin A—making them a healthier alternative to traditional fries without sacrificing flavor. Serve them as a side to burgers, tacos, or even as a standalone snack. The versatility is what makes this recipe a game-changer for any meal.
Ingredients for spiralized sweet potato fries
Nine simple ingredients deliver restaurant-quality crispy sweet potato fries without excess oil.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Organic preferred, no blemishes |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light variety for crispiness |
| Smoked Paprika 🌶️ | 1 tbsp | High-quality for smoky flavor |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Cayenne Pepper 🔥 | ½ tsp | Adjust for heat preference |
| Ground Cinnamon 🌿 | ½ tsp | Optional for sweet-spicy kick |
| Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Avocado Oil 🫒 | 1 tbsp | High smoke point for frying |
| Fresh Lemon Juice 🍋 | 1 tbsp | Brightens flavor after cooking |
| Unsweetened Coconut Flakes 🥥 | 1 tbsp | Optional for extra crunch |
Sweet potatoes make all the difference here—organic varieties like Beauregard hold their shape best. Grab them from Trader Joe's or your local farmers market for the freshest, most flavorful results. The skin should be smooth and vibrant, not wrinkled or soft. If you can't find organic, regular sweet potatoes work fine, just scrub them well. For spiralizing, a mandoline or spiralizer attachment is ideal, but a sharp knife works in a pinch. Aim for ⅛-inch thick strands for even cooking.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Short on avocado oil? Grapeseed or sunflower oil works for high-heat cooking. The cayenne and cinnamon are optional but worth it—cinnamon adds warmth while cayenne gives that subtle kick. For extra crunch, toss the finished fries with crushed panko breadcrumbs instead of coconut flakes. Fresh lemon juice is key for brightness—bottled won't cut it. If you're air frying, line the basket with parchment paper for easy cleanup.
Spiralized sweet potatoes keep for 3 days in the fridge, wrapped tightly in a damp towel to maintain moisture. For longer storage, freeze them raw in a single layer on a tray, then transfer to a bag for up to 3 months. Reheat frozen fries directly from frozen in the air fryer for 8-10 minutes at 400°F. These fries reheat beautifully—5 minutes in the oven at 425°F restores that crispy texture perfectly. Portion into serving containers ahead of time for easy snacking or game day prep.
Why You'll Love This Recipe

Step-by-step instructions for crispy spiralized sweet potato fries
Transform ordinary sweet potatoes into restaurant-quality fries with perfect texture and flavor.
Spiralize and Prep the Sweet Potatoes
Wash and dry the 2 whole large sweet potatoes thoroughly to remove any dirt or moisture. Using a mandoline or vegetable spiralizer, cut them into thin, even strands—about ¼-inch thick. I like to work in batches if needed to avoid overcrowding the spiralizer, which can cause uneven cuts.
Spread the spiralized sweet potato strands on a clean kitchen towel and pat them dry completely. This step is crucial—any moisture left on the fries will prevent them from becoming crispy. Arrange them in a single layer and let them air-dry for 15-20 minutes while you prepare the seasoning mix.
Season the Sweet Potato Fries
In a small bowl, combine the 1 tablespoon smoked paprika, 1 teaspoon garlic powder, ½ teaspoon cayenne pepper, ½ teaspoon ground cinnamon, and 1½ teaspoons sea salt. Mix well until the spices are evenly distributed and there are no visible streaks of any single spice.
Transfer the seasoning blend to a large resealable plastic bag. Add the dried sweet potato strands and gently shake the bag until every strand is fully coated with the spice mixture. You should see a uniform reddish-brown color on all the fries. This even coating ensures consistent flavor and crispiness throughout.
Par-Cook for Perfect Texture
Heat a large skillet over medium heat and add 1 tablespoon avocado oil. Once the oil is shimmering but not smoking, add half of the seasoned sweet potato strands in a single layer. Cook for 4-5 minutes, stirring occasionally with a spatula, until the fries are slightly softened but not yet browned.
Transfer the par-cooked fries to a clean plate and repeat with the remaining strands. The goal here is to partially cook the sweet potatoes so they finish perfectly in the oven. If you skip this step, the fries might end up undercooked or overly crispy on the outside while still soft inside.
Bake to Crispy Perfection
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Arrange the par-cooked sweet potato fries in a single layer on the baking sheet, leaving about ½ inch of space between each strand. This spacing allows hot air to circulate evenly, ensuring crispy fries all around.
Drizzle the ¼ cup extra-virgin olive oil evenly over the fries, tossing gently to coat them lightly. Bake for 15-20 minutes, flipping the fries halfway through, until they are deep golden brown and crispy to the touch. The fries are done when they release easily from the parchment paper and have a satisfying crunch.
Finish with Lemon and Coconut
Remove the fries from the oven and immediately transfer them to a serving bowl. Drizzle with 1 tablespoon fresh lemon juice and sprinkle with 1 tablespoon unsweetened coconut flakes for added texture and brightness. Toss gently to distribute the lemon juice evenly—this adds a refreshing tang that balances the smoky, spicy flavors.
Serve immediately while the fries are still hot and crispy. For extra crunch, you can also sprinkle with additional sea salt or a pinch of cayenne pepper. These fries pair beautifully with a creamy dipping sauce or a cool yogurt-based dip, but they're delicious on their own too.
Pro Tips For Making Spiralized Sweet Potato Fries
- PAT THEM DRY: Spiralized sweet potatoes hold onto moisture like they’re auditioning for a water retention competition. After slicing, lay them out on a clean kitchen towel and press gently with another towel—this cuts frying time and guarantees crispy edges instead of soggy noodles. (Yes, even if you’re impatient like me.)
- PREHEAT LIKE IT’S 1985: Your oven or air fryer needs to hit 425°F before the sweet potatoes go in. I learned this the hard way—starting with a lukewarm appliance means uneven cooking and a sad, limp pile of fries. Let it roar for 10 minutes first, no excuses.
- SALT THE SPIRALS: Toss those fresh spirals with a pinch of salt right after slicing. This draws out excess moisture, so they crisp up faster and don’t turn into a greasy mess. Skip this, and you’re basically frying wet noodles—no one wants that.
- TURN THEM ONCE: Overcrowding is the enemy of crispiness. Fry in a single layer, and when you flip, do it once—not twice or three times. The first flip (after 8–10 minutes) is the only one that matters. Resist the urge to poke and prod; patience here means perfect fries.

Nutrition facts
Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes won't give you the same sweet, caramelized flavor or vibrant color. Sweet potatoes have a lower moisture content and natural sugars that crisp beautifully when spiralized. If you must substitute, try yellow potatoes—they'll be slightly less sweet but still crispy.
How do I get the fries extra crispy?
Pat the spiralized sweet potatoes thoroughly dry first and let them air-dry for 15-20 minutes. Use avocado or grapeseed oil for high-heat cooking, and bake at 425°F until golden brown. For maximum crunch, bake in a single layer with space between strands.
What's the best way to reheat leftover fries?
Reheat in an air fryer at 400°F for 5-7 minutes or in the oven at 425°F for 5 minutes. Avoid microwaving—they'll lose their crispiness. For extra crunch, sprinkle with a little water and bake again.
Can I make these fries gluten-free?
This recipe is naturally gluten-free. Just ensure your spices and seasonings are certified gluten-free. The coconut flakes are also gluten-free, but check the label if using other toppings.
Why did my fries turn out soggy?
Sogginess usually means moisture wasn't removed properly or the oven wasn't hot enough. Always pat the fries completely dry and preheat the oven to 425°F. For extra insurance, par-cook them in a skillet first before baking.
