Ingredients
Here’s what you need to make crispy oven sweet potato fries:
- Sweet potatoes
- Olive oil
- Spices: smoked paprika, garlic powder, cayenne pepper, salt, black pepper
- Cornstarch
Sweet potatoes are the heart of this dish. They give a natural sweetness and a vibrant color. Use two large ones, peeled and cut into even fries. This helps them cook evenly.
Next, olive oil adds a rich flavor and helps the fries crisp up nicely. You will need two tablespoons.
For the spices, smoked paprika gives a nice depth, while garlic powder adds a kick. Add cayenne pepper for heat if you like spice. Use one teaspoon of smoked paprika, one teaspoon of garlic powder, half a teaspoon of cayenne, one teaspoon of salt, and half a teaspoon of black pepper.
Finally, cornstarch is key for that crunchy texture. Just one tablespoon will do the trick.
Gather these ingredients, and you're ready to start cooking. Each one plays an important role in making your sweet potato fries delicious and crispy.

Step-by-Step Instructions
Preheat the Oven
First, set your oven to 425°F (220°C). This high heat helps the fries get crispy. While the oven warms up, line a large baking sheet with parchment paper. This makes cleanup easier and helps prevent sticking.
Prepare the Sweet Potatoes
Next, take your two large sweet potatoes. Peel them, then cut them into evenly sized fries. In a big bowl, add the sweet potato fries. Drizzle them with two tablespoons of olive oil. Then, sprinkle in one teaspoon of smoked paprika, one teaspoon of garlic powder, half a teaspoon of cayenne pepper, one teaspoon of salt, and half a teaspoon of black pepper. Toss everything together until the fries are fully coated.
Crisp Them Up
Now, it’s time to add some cornstarch. Sprinkle one tablespoon of cornstarch into the bowl. Toss the sweet potatoes again. The cornstarch helps give the fries that lovely crunch we all want!
Arrange for Baking
Take the coated fries and lay them out in a single layer on your lined baking sheet. Make sure to leave space between each fry. This helps them cook evenly and get crispy all around.
Bake the Fries
Put the baking sheet in the oven to bake. Set a timer for 25 to 30 minutes. Halfway through, flip the fries with a spatula. This helps them brown evenly and get that perfect crispy texture.
Finish and Serve
When the fries are golden and crispy, take them out. Let them cool for a few minutes before serving. This helps them set and keeps that crunch. Serve them in a cute basket with your favorite dipping sauce for extra flavor!
Tips & Tricks
Achieving Maximum Crispiness
To make crispy oven sweet potato fries, start with the right prep. Cut the sweet potatoes into even pieces. This helps them cook at the same rate. Use cornstarch for extra crunch. Toss the fries in it after adding oil and spices. This step is key to a crispier fry.
Optimal Baking Techniques
Baking fries at 425°F (220°C) is perfect for crispiness. Preheat the oven well before baking. Line your baking sheet with parchment paper. It keeps fries from sticking and helps with even cooking. Spread the fries in a single layer. This prevents them from steaming and keeps them crispy.
Timing and Temperature Insights
Bake the fries for 25-30 minutes. Flip them halfway through to ensure they brown evenly. Keep an eye on them to avoid burning. The goal is golden and crispy, not burnt. Let them cool for a few minutes after baking. This helps the fries set their crunchiness.
Pro Tips
- Choose the Right Sweet Potatoes: Look for firm, unblemished sweet potatoes for the best flavor and texture.
- Soak for Extra Crispiness: Soaking the fries in cold water for 30 minutes before baking can help remove excess starch, leading to crispier fries.
- Use a High-Quality Baking Sheet: A heavy-duty baking sheet can help distribute heat evenly, ensuring your fries cook perfectly.
- Experiment with Spices: Feel free to mix up the spices according to your taste; try adding cumin or chili powder for a different flavor profile.
Variations
Different Spice Combinations
You can change the flavor of your sweet potato fries easily. Try using cinnamon and sugar for a sweet treat. For a zesty twist, add lime zest and chili powder. If you love herbs, mix in dried rosemary or thyme. Each spice blend offers a new taste adventure. Experiment and find your favorite!
Sweet Potato Fries with Parmesan
Adding Parmesan cheese can make your fries even better. After baking, sprinkle grated Parmesan on top. The cheese melts and adds a savory flavor. For extra flair, mix the cheese with herbs like parsley or oregano. This combo makes your fries cheesy and delicious!
Healthier Versions (Air Fryer or Other Cooking Methods)
Want a lighter option? You can use an air fryer to cook your fries. Air frying cuts down on oil and keeps them crispy. Just toss the sweet potatoes with the same spices and cornstarch. Cook them at 400°F (200°C) for about 15-20 minutes. You’ll get crispy fries with less fat! You can also roast them on a grill for a smoky flavor.
Storage Info
How to Store Leftover Fries
To store leftover sweet potato fries, let them cool first. Place them in an airtight container. You can put a paper towel inside to absorb moisture. Store in the fridge for up to three days. This keeps them fresh and tasty.
Reheating Instructions
When you are ready to enjoy the fries again, preheat your oven to 400°F (200°C). Spread the fries on a baking sheet in a single layer. Heat them for about 10-15 minutes. This helps them regain their crispiness. You can also use an air fryer if you want a quicker option.
Tips to Maintain Crispiness
To keep fries crispy, avoid stacking them in the fridge. Give them space in the container. When reheating, ensure they are in a single layer on the baking sheet. This allows hot air to circulate. For extra crunch, sprinkle a little cornstarch before reheating.
