Side Dishes
Sweet potato spirals transform humble sweet potatoes into a crispy, golden side dish that steals every meal. The secret lies in spiralizing them just right—thin enough for quick cooking, thick enough to hold their shape—then roasting until the edges crackle with caramelized perfection while the centers stay tender.
I developed this recipe after years of experimenting with spiralized vegetables, and it’s finally the one that delivers restaurant-quality results at home without the fuss.
What makes these spirals special is the two-stage roasting technique: starting with a high-heat blast for crispiness, then finishing at a lower temperature to ensure the centers cook through.
A simple seasoning of olive oil, salt, and smoked paprika creates a flavor profile that works with everything from grilled meats to hearty soups. The result? A dish that looks impressive but requires just 20 minutes of active prep and 25 minutes in the oven.
Each bite delivers a satisfying contrast of crispy edges and fluffy, buttery cores, making these spirals irresistible as a standalone side or part of a larger spread. They reheat beautifully too, so you can prepare them ahead and keep them warm until serving.
The versatility is another win—the same method works for regular or orange-fleshed sweet potatoes, and you can easily adapt the seasoning for vegan or gluten-free diets.
Serve alongside roasted chicken, blackened fish, or even as a vibrant centerpiece for vegetarian bowls. The golden-brown spirals add visual appeal and texture that elevates any plate.

Ingredients for sweet potato spirals
This crispy, golden side dish delivers restaurant-quality texture with just eight quality ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Orange-fleshed, firm variety preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For crispy edges and richness |
| Smoked Paprika 🌶️ | 1 tsp | For depth and smoky flavor |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | For balanced seasoning |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | ¼ tsp | For subtle aromatic depth |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ⅛ cup | Leaves only, finely chopped |
| Unsalted Butter 🧈 | 2 tbsp | Melted, for brushing |
The sweet potatoes are the foundation—choose firm, vibrant orange-fleshed varieties like Beauregard or Jewel. Whole Foods or Trader Joe's carry excellent options, but any well-stocked grocery store works. Avoid those with soft spots or green patches. For the best results, spiralize them just before roasting to prevent browning. A mandoline with a spiral blade gives the most even thickness, but a vegetable peeler works in a pinch. The key is consistency—aim for about 1/4-inch thick spirals for perfect crispy edges and tender centers.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works, though it won't be identical. Fresh herbs wilt fast, so dried rosemary and thyme at half the amount are fine substitutes. The olive oil matters—avoid the cheap stuff. A good extra-virgin like California Olive Ranch or Colavita makes all the difference. For extra richness, add 1 tablespoon of nutritional yeast to the seasoning mix. And if you're short on time, pre-cut spiralized sweet potatoes from the produce section (yes, they exist!) save 15 minutes of prep.
Spiralized potatoes oxidize fast, so toss them with a light coating of olive oil immediately after cutting to preserve color. Store any extras in an airtight container with parchment paper between layers—keeps them fresh for 2 days in the fridge. For longer storage, freeze the uncooked spirals on a baking sheet first (to prevent sticking), then transfer to a bag. They'll keep for 3 months. Reheat directly from frozen at 400°F for 15-20 minutes, adding 5 minutes if they're thick. The crispiness diminishes slightly after reheating, so make fresh whenever possible for that perfect crunch.

Step-by-step instructions for sweet potato spirals
Achieving crispy edges and fluffy interiors requires precision—follow these steps exactly.
Prep and Spiralize the Sweet Potatoes
Begin by thoroughly washing the 2 whole large sweet potatoes to remove any dirt. Using a vegetable peeler, carefully peel away the skin, leaving the flesh intact. This step ensures clean, even spirals without fibrous bits that can interfere with texture.
Cut each sweet potato in half lengthwise, then place one half in a spiralizer. I recommend starting with the flat side down to maintain stability. Run the sweet potato through the spiralizer, applying gentle but steady pressure. You should end up with approximately 4-5 long, even spirals per potato. If any pieces break, set them aside for roasting separately—they'll still taste delicious.
Toss with Seasoned Olive Oil
In a large bowl, combine the 0.25 cup extra-virgin olive oil with the 1 tsp smoked paprika, 0.5 tsp diamond crystal kosher salt, 0.25 tsp ground black pepper, and 0.25 tsp garlic powder. Whisk vigorously until the spices are fully dissolved and the oil takes on a deep, aromatic hue.
Transfer the sweet potato spirals to the bowl and toss gently but thoroughly to coat each strand evenly. The oil should cling to the spirals without pooling at the bottom. This even distribution is critical for achieving consistent crispiness throughout. I like to use my hands for this step—it ensures every nook gets coated, but be careful not to overhandle, which can compress the delicate spirals.
Add Fresh Herbs and Mix
In a separate small bowl, combine the 0.25 cup finely chopped fresh rosemary and 0.125 cup fresh thyme leaves. Sprinkle this herb mixture over the seasoned sweet potato spirals and toss again, this time using a silicone spatula to avoid breaking the strands. The herbs should be evenly distributed but not overpowering—they'll infuse subtle aromatic depth as they crisp.
Let the seasoned spirals rest in the bowl for 5 minutes. This brief marinating period allows the flavors to meld slightly and the sweet potatoes to absorb the seasoning more deeply. The spirals will look vibrant and fragrant—this is your cue that they're ready for the oven.
Arrange and Roast for Crispy Perfection
Preheat your oven to 425°F. Line two baking sheets with parchment paper, leaving space between the sheets for easy transfer. Arrange the sweet potato spirals in a single layer on the prepared sheets, spacing them about 1 inch apart. This spacing ensures even airflow and prevents steam buildup, which can lead to soggy rather than crispy results.
Roast for 20-25 minutes, flipping the spirals halfway through at the 12-minute mark. You'll know they're ready when the edges are deep golden brown and the spirals pull away from the baking sheet with slight resistance. The internal temperature should reach 200°F—this ensures the cores remain tender while the edges achieve that coveted crispiness. If any pieces brown too quickly, rotate the baking sheets for even cooking.
Finish with Melted Butter
While the spirals are still hot, melt the 2 tbsp unsalted butter in a small saucepan over low heat. Once fully melted, remove from heat and immediately brush the butter evenly over the roasted sweet potato spirals. The residual heat will create a glossy sheen and enhance the natural sweetness of the potatoes.
Transfer the spirals to a serving platter and let them rest for 3-5 minutes before serving. This brief resting period allows the flavors to settle and the crispy edges to firm up slightly. Serve immediately while still warm, garnished with any remaining fresh herbs. The contrast of crispy, caramelized edges with tender, fluffy centers makes these spirals irresistible—exactly as promised.
Pro Tips For Making Sweet Potato Spirals
- USE A HOT SKILLET: The spirals won’t crisp up properly if your pan is lukewarm—get it screaming hot over medium-high before adding the oil. I used to rush this, and the potatoes would just steam instead of developing that golden, caramelized crust you’re after.
- PEEL AND SPIRAL COLD POTATOES: Let the sweet potatoes sit out for 30 minutes after peeling so they’re cool to the touch—warm potatoes squirt everywhere when you spiralize. I learned this the hard way after watching a spiralizer go flying across the kitchen.
- SALT BEFORE SPIRALIZING: Toss the whole peeled potatoes with a pinch of kosher salt before cutting them into spirals—it keeps them from turning mushy while cooking. Sounds weird, but it works: the salt draws out just enough moisture to guarantee crisp edges.
- DON’T OVERCROWD THE PAN: Work in batches if needed—two layers of spirals will steam instead of brown. A single even layer (about ½ inch thick) is all you need, and it cooks faster. Your future self will thank you when the first batch is ready in 8 minutes instead of 15.
Storing and reheating this recipe
Fridge Storage Tips
Store uncooked sweet potato spirals in an airtight container with parchment paper between layers to prevent sticking. They’ll stay fresh for 2 days in the fridge, but I recommend cooking them fresh for maximum crispiness.
If you must store them, toss with a light coating of olive oil before refrigerating to preserve color and texture. 🥬
Freezer Prep for Later
For longer storage, arrange uncooked spirals on a baking sheet in a single layer and freeze for 1 hour to prevent clumping. Transfer to a freezer bag with all air removed—this keeps them crispy for up to 3 months.
When ready to cook, bake straight from frozen at 400°F for 25-30 minutes, adding 5 extra minutes if they’re thick. The texture won’t be as crispy as fresh, but it’s still delicious. ❄️
Reheating Crispy Edges
Reheat leftover spirals in a 400°F oven for 10-12 minutes until warmed through and edges regain crispiness. For a quick fix, use the air fryer at 375°F for 5 minutes, shaking halfway.
Avoid the microwave—it’ll turn them soggy. Brush with a little melted butter after reheating to restore that golden sheen. 🔥
Make-Ahead for Meals
Prep the spirals ahead and store them in the fridge until ready to roast—this cuts active time to just 10 minutes. I often do this when hosting dinner parties.
For large gatherings, spiralize and season all ingredients the night before, then roast while the main dish cooks. The flavors develop even better overnight, making them extra aromatic. 💡
Reviving Stale Spirals
If your spirals lose crispiness, pop them back in the oven at 400°F for 3-5 minutes to refresh. For extra crunch, toss with 1 tsp olive oil and ½ tsp smoked paprika before reheating.
This trick works wonders for restoring texture without sacrificing flavor. A quick broil for 2 minutes at the end gives them that restaurant-style crisp again. ✨
Serving Warm vs. Room Temp
Sweet potato spirals taste best piping hot, but they’re still great at room temperature for up to 2 hours. If serving cold, drizzle with extra-virgin olive oil and a pinch of flaky sea salt to enhance flavor.
For warm servings, keep them covered in a 200°F oven while the main dish cooks—this maintains crispiness. 🍽️
Nutrition facts
Frequently asked questions
What's the best thickness for sweet potato spirals?
Aim for ¼-inch thick spirals—they crisp up perfectly while keeping tender centers. Too thin (⅛-inch) burns quickly, while thicker (½-inch) stays too soft. A mandoline with adjustable blades makes this easy to control.
Can I use regular potatoes instead of sweet potatoes?
No, the natural sweetness and moisture content of sweet potatoes make them ideal for this recipe. Regular potatoes lack the caramelization potential and will turn out bland or starchy. For a similar texture, try butternut squash spirals instead.
How do I prevent my spirals from sticking together?
Toss the spirals with 1 tsp olive oil immediately after cutting, then spread them single-layer on parchment-lined sheets. For extra insurance, sprinkle with ½ tsp cornstarch before roasting. Never skip this step—it's what creates that perfect crispy texture!
What if my oven isn't 425°F?
Use the highest temperature your oven can reach—450°F works great if available. For lower temps (375°F), increase roasting time by 5-7 minutes and flip more frequently. The key is getting those edges golden brown while keeping centers tender.
Can I make these in an air fryer?
Arrange spirals in a single layer in your air fryer basket and cook at 375°F for 10-12 minutes, shaking halfway. Watch closely—they crisp faster than in the oven. A light spray of olive oil before air frying helps achieve that perfect crunch.
