Ingredients for sweet potato fries recipe cinnamon
Nine simple ingredients transform ordinary sweet potatoes into restaurant-quality cinnamon-spiced fries.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium-sized, peeled and cut |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For tossing and crisping |
| Ground Cinnamon 🌶️ | 1 ½ tbsp | True Ceylon preferred |
| Smoked Paprika 🌶️ | ½ tbsp | For smoky depth |
| Cayenne Pepper 🔥 | ¼ tsp | Adjust for heat preference |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For finishing |
| Garlic Powder 🧄 | ½ tsp | For aromatic balance |
| Baking Powder 🍞 | ½ tsp | For extra crispiness |
The sweet potatoes are the foundation—orange-fleshed varieties like Jewel or Beauregard work best. Trader Joe's and Whole Foods carry them year-round, but check the produce section for firm, heavy tubers. Avoid any with soft spots or sprouting eyes. For even cooking, cut them into 1/4-inch thick sticks—consistent size is key for crispiness. The cinnamon should be Ceylon if available—it’s milder and sweeter, but regular ground cinnamon works too. I always grab my spices from Penzeys for that extra depth of flavor.
No Ceylon cinnamon? Regular ground cinnamon still delivers, though you might need a touch more. Smoked paprika can be swapped for regular paprika, but you’ll lose that subtle smokiness. The cayenne is optional—skip it if you prefer mild heat. For a quick prep, use pre-cut frozen sweet potato fries (just thaw and pat dry first). The baking powder might seem odd, but it’s a game-changer for extra crispiness—trust me on this. If you’re short on time, toss the fries with a little cornstarch instead (1 tbsp) for a similar effect.
These fries keep their crispiness best when served immediately, but they reheat beautifully. Toss them in the oven at 400°F for 5-7 minutes to restore that golden crunch. For storage, keep them in an airtight container for up to 3 days—they’ll lose some crispness but still taste amazing. Freezing isn’t ideal for texture, but you can freeze them before baking for up to 2 months. I like to make a double batch on Sundays so I always have crispy fries ready for the week.

Step-by-step instructions for sweet potato fries with cinnamon
Here's how to achieve perfectly crispy sweet potato fries with warm, aromatic spices every time.
Prepare the Sweet Potatoes for Even Cooking
Start by peeling the 2 lbs sweet potatoes using a vegetable peeler or sharp knife. Cut them into even ¼-inch thick sticks, about 3-4 inches long. Uniform size ensures they cook at the same rate and develop crispy edges simultaneously.
Place the cut fries in a large bowl and immediately add ½ teaspoon of the 1.5 teaspoons kosher salt and ½ teaspoon of the 0.5 teaspoon baking powder. Toss gently with your hands to distribute the seasoning evenly. The baking powder helps create an extra crispy texture by promoting browning. Let them sit for 10 minutes while you prepare the oven.
Toss Fries in Olive Oil and Spice Blend
Preheat your oven to 425°F with an oven rack positioned in the middle position. Line two large baking sheets with parchment paper for easy cleanup. In a large bowl, combine the remaining 1 teaspoon kosher salt, 1.5 tablespoons ground cinnamon, 0.5 tablespoon smoked paprika, 0.25 teaspoon cayenne pepper, 0.5 teaspoon garlic powder, and 0.5 teaspoon freshly ground black pepper.
Add the 0.25 cup extra-virgin olive oil to the bowl with the spice mixture and pour the sweet potato fries into the bowl. Toss everything together until every fry is thoroughly coated in the oil and spice blend. You should see the fries glistening with oil and lightly dusted with spices. This coating is what creates that perfect balance of crispy exterior and tender interior.
Bake in Batches for Perfect Crispiness
Spread the fries in a single layer on the prepared baking sheets, leaving about ½ inch of space between each fry. This prevents them from steaming and ensures maximum crispiness. Bake for 20-25 minutes, flipping the fries halfway through cooking at the 12-15 minute mark. You're looking for fries that are deep golden brown and crispy to the touch.
Here's the thing—don't overcrowd the baking sheets. If you try to fit too many fries on at once, they'll steam instead of crisp. The fries should be in one even layer with no overlaps. The high heat and proper spacing create that satisfying crunch while keeping the inside tender. For best results, use both baking sheets to cook in batches if needed.
Finish with Freshly Ground Black Pepper
Remove the fries from the oven and immediately transfer them to a serving platter. While they're still hot, sprinkle with any remaining 0.5 teaspoon freshly ground black pepper for a final burst of flavor. The pepper adds a subtle warmth that complements the sweetness of the cinnamon and smokiness of the paprika.
Serve immediately while the fries are at their crispest. These sweet potato fries should have a perfect balance of textures—crispy on the outside, tender on the inside, with a warm spice harmony that makes every bite satisfying. If you need to keep them warm for a short time, place them on a wire rack set over a baking sheet in a 200°F oven for up to 10 minutes to maintain crispness.
Pro Tips For Making Sweet Potato Fries Recipe Cinnamon
- CRANK THE HEAT THEN DROP IT: Sweet potatoes need that first blast of 375°F (190°C) to crisp properly, but after 10 minutes, cut to 325°F (165°C) or they’ll turn to mush. I learned this the hard way—skipping the temp drop means soggy fries, no matter how much oil you use.
- PEEL AND CUT WHEN COLD: Run your sweet potatoes under cold water first, then peel and slice them. Warm potatoes release starch like crazy, making your fries glue together in the oil. Cold prep = cleaner cuts and crispier results every time.
- SALT BEFORE SEASONING: Toss the sliced fries in a pinch of salt before adding the cinnamon-spice mix. The salt helps draw out moisture, so the spices stick better and the fries get that perfect caramelized crust. (Yes, even if you’re impatient like me.)
- DON’T OVERMIX THE SPICES: After baking, sprinkle the cinnamon, smoked paprika, and cayenne lightly—just enough to coat. Dumping in a full tablespoon of each per pound of fries will make them taste like a spice shop exploded. Start with ½ teaspoon per pound and adjust.
Health benefits of sweet potato fries recipe cinnamon
Blood Sugar Balance
Sweet potatoes are a low-glycemic food, meaning they release energy slowly and help stabilize blood sugar levels—critical for anyone managing diabetes or insulin resistance. The 1.5 tbsp cinnamon in this recipe further enhances this benefit by improving insulin sensitivity.
I’ve noticed my energy levels stay steadier when I include these fries in meals, especially when paired with lean protein like grilled chicken. 💪
Rich in Beta-Carotene
The vibrant orange color of sweet potatoes comes from beta-carotene, a powerful antioxidant converted to vitamin A in your body. A 1-cup serving of these fries provides about 400% of your daily vitamin A needs, supporting vision, immune function, and healthy skin.
The cinnamon doesn’t interfere with absorption—it actually enhances the sweetness, making them more enjoyable to eat regularly.
Fiber for Digestion
With 5 grams of fiber per serving, these fries promote healthy digestion and keep you feeling full longer. The cinnamon adds a warming touch that aids digestion, while the baking powder helps create that crispy texture without sacrificing fiber content.
I always make a double batch on weekends because the fiber keeps me satisfied through busy days. 🌱
Anti-Inflammatory Benefits
Cinnamon contains anti-inflammatory compounds like cinnamaldehyde, which help reduce chronic inflammation in the body. Combined with sweet potatoes’ high levels of polyphenols, this recipe becomes a natural remedy for inflammation.
I’ve found that adding these fries to my meals helps me recover faster after workouts, thanks to their combined benefits.
Heart-Healthy Fats
The extra-virgin olive oil used for tossing provides monounsaturated fats, which support heart health by lowering bad cholesterol. The cinnamon also helps regulate blood pressure, making this a heart-smart snack.
I love serving these fries as a side to grilled salmon for a complete heart-healthy meal. The olive oil’s antioxidants work synergistically with the cinnamon’s anti-inflammatory properties. ✨

Frequently asked questions
Can I use regular cinnamon instead of Ceylon?
Yes, you can! Regular ground cinnamon works perfectly fine—just use the same amount (1.5 tablespoons). Ceylon is milder and sweeter, but regular cinnamon adds a deeper warmth that still pairs beautifully with the sweet potatoes. If you prefer a touch less spice, reduce the cayenne slightly (0.125 teaspoon) to balance the flavors.
How do I make these fries extra crispy?
For maximum crispiness, bake at 425°F with no crowding on the sheets—leave ½ inch between fries. Toss them with 1 tablespoon cornstarch before baking (in addition to the oil) for a crunchier texture. Also, flip them halfway through cooking (12-15 minutes) to ensure even browning. Air fryers work too—try 375°F for 12-15 minutes, shaking the basket every 5 minutes.
What’s the best way to reheat these fries?
Reheat in a 400°F oven for 5-7 minutes on a wire rack over a baking sheet to restore crispiness. For the air fryer, use 375°F for 3-4 minutes—shake the basket halfway. Avoid microwaving, as it makes them soggy. If storing, keep in an airtight container for up to 3 days (they’ll lose some crispness but still taste great).
Can I make these fries ahead of time?
Prep the fries up to 24 hours ahead—store them in an airtight container in the fridge. Toss them with a little extra oil (1 teaspoon) before baking to refresh the coating. For longer storage, freeze uncooked fries for up to 2 months—thaw overnight in the fridge before baking. Cooking from frozen adds 3-5 extra minutes to the bake time.
What’s the secret to balancing the sweetness and spice?
The key is the smoked paprika and cayenne—they add depth without overpowering. Start with the full 0.25 teaspoon cayenne, then adjust to taste. For a sweeter finish, sprinkle with 1 teaspoon honey or a pinch of flaky sea salt after baking. The cinnamon’s warmth enhances the sweetness naturally, so don’t rush the baking time—let them caramelize for that perfect harmony.
