Ingredients for sweet potato fries recipe cinnamon
Nine simple ingredients transform ordinary sweet potatoes into restaurant-quality cinnamon-spiced fries you'll crave repeatedly.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Organic preferred, peeled and sliced thin |
| Ground Cinnamon 🌿 | 1 tbsp | True Ceylon for authentic flavor |
| Granulated Sugar 🍬 | 2 tbsp | Coconut sugar for deeper caramel notes |
| Avocado Oil 🫒 | 1 tbsp | High smoke point for crisping |
| Diamond Crystal Kosher Salt 🧂 | 1 tsp | Fine grain for even coating |
| Ground Nutmeg 🌶️ | ¼ tsp | Freshly grated for aromatic depth |
| Cornstarch 🌾 | 1 tbsp | For ultra-crispy texture |
| Garlic Powder 🧄 | ½ tsp | Enhances sweet-spice balance |
| Unsalted Butter 🧈 | 1 tbsp | Melted for brushing |
Sweet potatoes are the star—organic, vibrant orange ones from Whole Foods or local farmers markets have the best natural sweetness. Peel them first, then slice into ¼-inch thick rounds (a mandoline makes this foolproof). For cinnamon, Penzeys' Ceylon variety delivers that warm, floral note without bitterness—worth the splurge if you're a spice lover. Store-bought ground cinnamon works fine, but if you see those little black specks in your bottle, toss it. Freshly ground nutmeg? Toast the whole nutmeg for 30 seconds before grinding—game-changer for aroma. And that avocado oil? Trader Joe's or Costco have the best-priced high-smoke-point versions—essential for crisping without burning.
No Ceylon cinnamon? Cassia works in a pinch (just reduce to ¾ tbsp to avoid bitterness). Out of cornstarch? Arrowroot powder or even extra flour (but use ½ tbsp less) keeps them crispy. Want to skip the butter brushing? Drizzle with melted coconut oil instead—same crispy magic, plant-based approved. The sugar can be swapped for maple syrup (1.5 tbsp) if you prefer a deeper caramel flavor, but it'll be stickier. Pro tip: Toss the fries in cornstarch right before baking—that extra step makes all the difference for crispy edges. And if you're feeling fancy, add a pinch of smoked paprika to the cinnamon-sugar mix for a BBQ-spiced twist.
These fries reheat beautifully—5 minutes at 400°F brings back that crispy texture. Store leftovers in an airtight container for up to 4 days, but honestly? They vanish faster than that. For meal prep, bake a double batch and freeze half on a parchment-lined tray before transferring to a bag. They keep 3 months frozen and crisp up perfectly. The cinnamon-sugar coating? Double the batch—you'll want it for everything from oatmeal to yogurt. And that leftover avocado oil? Save it—it's perfect for roasting veggies or sautéing garlic.

Step-by-step instructions for sweet potato fries with cinnamon
Here's how to transform humble sweet potatoes into irresistibly crispy, spiced fries with a perfect crunch.
🍳 Step 1: Prep and Season the Sweet Potatoes
Start by peeling the 2 whole large sweet potatoes with a vegetable peeler or sharp knife. I like to cut them into even ¼-inch thick sticks using a mandoline for consistency—this ensures they cook uniformly. Immediately place them in a large bowl and toss with the 1 tablespoon avocado oil until they're evenly coated and glistening.
In a small bowl, whisk together the 1 tablespoon ground cinnamon, 2 tablespoons granulated sugar, 1 teaspoon Diamond Crystal kosher salt, 0.25 teaspoon ground nutmeg, 0.5 teaspoon garlic powder, and 1 tablespoon cornstarch. Sprinkle this aromatic blend over the sweet potato sticks and toss vigorously with your hands until every piece is completely coated. The cornstarch is key here—it creates that irresistible crunch we're after.
🔥 Step 2: Par-Cook for Perfect Texture
Arrange the seasoned sweet potato fries in a single layer on a parchment-lined baking sheet. I like to leave about ½-inch between each piece to allow for even cooking. Place the sheet on the middle rack of your oven and bake at 400°F for 15 minutes. You're not cooking them all the way through yet—just par-cooking until they're tender when pierced with a fork but still firm.
This par-cooking step is crucial. It prevents the fries from turning mushy when you finish them in the oven. You'll know they're ready when they yield slightly to pressure but still have a bit of resistance in the center. Remove them from the oven and let them cool for 5 minutes—this resting period helps them crisp up beautifully in the final step.
🔥 Step 3: Achieve the Ultimate Crisp
While the fries cool, melt the 1 tablespoon unsalted butter in a small microwave-safe bowl for 20-30 seconds until just liquid. Return the par-cooked fries to the oven (no need to preheat) and bake for an additional 10-12 minutes at 425°F. This higher temperature is what creates that satisfying crunch we're after.
About 2 minutes before they're done, brush each fry generously with the melted butter. Watch closely—they should develop a beautiful golden-brown color with crisp edges. You'll know they're perfect when they sound hollow when shaken together in the pan. Remove them immediately to prevent over-browning, and transfer to a wire rack to cool for 3-4 minutes before serving.
🍽️ Step 4: Serve with Confidence
Serve these sweet potato fries immediately while they're still crispy and warm. The combination of cinnamon, nutmeg, and garlic powder creates a warm spice profile that perfectly complements the natural sweetness of the sweet potatoes. For extra indulgence, drizzle with a bit of honey or serve with a side of whipped cream.
Here's the thing about these fries—they're best enjoyed right away. As they cool, they'll lose some of that irresistible crunch, so don't wait too long. The perfect fry should have a crisp exterior that gives way to a tender, slightly caramelized interior. Each bite delivers that perfect balance of sweet, spicy, and crunchy that makes these fries unforgettable.
Pro Tips For Making Sweet Potato Fries Recipe Cinnamon
- CUT THICK, COOK FAST: I learned this the hard way—thin slices burn before they crisp. Use a mandoline or sharp knife to cut ½-inch thick sticks, then toss them in ice water for 10 minutes to stop cooking. Thicker fries stay tender inside while getting that perfect caramelized crust.
- SALT BEFORE SWEETENING: Diamond Crystal kosher salt is less dense, so use twice what you’d use with table salt. Sprinkle a generous pinch (about ½ teaspoon per pound of fries) before tossing in the cinnamon-sugar mix—this balances the sweetness and keeps the coating from clumping.
- DON’T OVERCROWD THE PAN: I used to dump all the fries in at once, thinking I’d save time. Wrong. Overcrowding steams them instead of crisps. Cook in batches—no more than ½ inch deep—and let them sizzle freely for 3-4 minutes per side. A hot pan makes all the difference.
- TOSS WITH WET HANDS: The cinnamon-sugar mix sticks like glue if your hands are dry. Wet your fingers slightly before tossing the fries—it helps the coating adhere evenly without turning into a sticky mess. (Yes, it sounds odd, but it works.)
Creative variations of this dish
Spiced Caramel Glaze
Take these fries to dessert-level status with a spiced caramel glaze that drizzles perfectly over the crispy edges. Melt ¼ cup brown sugar with 2 tbsp heavy cream and ½ tsp cinnamon in a saucepan over medium heat until bubbly (3-4 minutes).
Stir in 1 tbsp butter until smooth, then immediately drizzle over the hot fries. The sugar caramelizes instantly, creating a sticky, aromatic coating that balances the crispy texture. 🍯
BBQ-Spiced Twist
Swap the cinnamon for a smoky-sweet BBQ-inspired blend by mixing 1 tbsp smoked paprika, 1 tsp chili powder, ½ tsp garlic powder, and 1 tbsp brown sugar into the coating. Toss the fries as usual, then bake at 425°F for 15 minutes until deeply caramelized.
Serve with a side of cool ranch or chipotle mayo for a sweet-heat contrast that’s perfect for game day. 🌶️
Honey-Lime Crunch
Brighten the warm spices with a zesty honey-lime finish. After baking, toss the fries with 1 tbsp honey and 1 tsp lime zest, then squeeze fresh lime juice over them.
The acidity cuts through the richness, while the honey adds a glossy sheen. Sprinkle with flaky sea salt for a sophisticated touch that elevates these fries to brunch-worthy status. 🍋
Chocolate-Dipped Bites
For a decadent variation, dip the still-warm fries halfway into melted dark chocolate (I love Ghirardelli 70% cocoa). Let the excess drip off, then sprinkle with crushed pecans or sea salt flakes.
The chocolate cools quickly, creating a crisp shell around the warm, spiced potato. Serve immediately as a dessert or late-night snack—trust me, you won’t be able to stop at one. 🍫
Global Spice Blends
Experiment with international flavor profiles by swapping the cinnamon blend. For Moroccan-inspired fries, use 1 tsp each cumin, coriander, and turmeric plus ½ tsp cayenne. For Japanese-inspired, mix 1 tsp ginger, ½ tsp sesame seeds, and a pinch of white miso paste into the coating.
Each blend transforms the fries into a completely different experience while keeping the crispy texture intact. 🗺️
Herbed Yogurt Dip
Balance the sweet-spiced fries with a cool, herbed yogurt dip that’s lighter than traditional sauces. Mix ½ cup Greek yogurt with 1 tbsp lemon juice, 1 tsp fresh dill, ½ tsp garlic powder, and a pinch of salt.
The tangy creaminess contrasts beautifully with the caramelized edges, making every bite feel fresh and balanced. 🥄

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can technically use white or russet potatoes, they won't deliver the same flavor or texture. Sweet potatoes have a natural sweetness that pairs perfectly with cinnamon, and their moisture content creates that ideal crispy exterior with tender interior. If you must substitute, try yams—but expect a slightly denser bite.
How do I get them extra crispy without burning?
The secret is the two-stage baking method! First bake at 400°F for 15 minutes to par-cook, then increase to 425°F for 10-12 minutes with melted butter brushed on last. Use avocado oil (high smoke point) and keep slices ¼-inch thick for even cooking. Crowding the pan causes steam—space them out!
Can I make these in an air fryer?
Toss the seasoned fries in the air fryer basket in a single layer and cook at 375°F for 12-15 minutes, shaking halfway. For extra crispiness, spray with avocado oil before the final 3 minutes. The air fryer works best for smaller batches—double-check your model's capacity to avoid overcrowding.
Why did my fries turn out soggy?
Soggy fries usually mean one of three things: uneven thickness (some cooked faster), overcrowding (steam instead of crisping), or skipping the resting period. Always slice uniformly, leave space between pieces, and let them rest 5 minutes after par-cooking before finishing. The cornstarch coating also helps—don't skip that step!
What's the best way to store leftovers?
Store in an airtight container for up to 4 days at room temperature, but they're best reheated. For longer storage, freeze on a parchment-lined tray before transferring to a bag (keeps 3 months). Reheat at 400°F for 5-7 minutes—they won't be as crispy but still delicious! The cinnamon-sugar coating stays flavorful even after reheating.
