Ingredients

For perfect Crispy Oven Baked Sweet Potato Fries, you’ll need:

• 2 large sweet potatoes (about 1.5 pounds or 680g), scrubbed clean
• 2 tablespoons (30ml) olive oil or avocado oil
• 2 teaspoons (10g) cornstarch
• 1 teaspoon (5g) garlic powder
• 1 teaspoon (5g) paprika (sweet or smoked)
• ½ teaspoon (2.5g) salt
• ¼ teaspoon (1.25g) black pepper
• Optional: ¼ teaspoon (1.25g) cayenne pepper for heat

The sweet potatoes are the star of this dish – look for firm, unwrinkled ones with vibrant orange flesh for the best flavor and texture. The cornstarch might seem unusual, but it’s the secret ingredient that draws out moisture and helps achieve that coveted crispy exterior. High-quality olive oil adds flavor, while avocado oil offers a higher smoke point if you prefer extra crispiness. The combination of garlic powder and paprika creates a savory base that complements the sweet potatoes’ natural sweetness perfectly.

Pro Tips

Uniform Cutting Technique
The most crucial step for achieving perfectly Crispy Oven Baked Sweet Potato Fries is cutting them into uniform sizes. Aim for sticks about ¼ inch (0.6cm) thick – too thin and they’ll burn, too thick and they’ll be soggy. For best results, first cut the sweet potato in half lengthwise, then slice each half into planks, and finally cut those planks into evenly-sized fries. Consistent thickness ensures they’ll cook at the same rate, giving you perfectly crispy fries throughout.

The Cold Water Soak
Don’t skip soaking your cut sweet potato fries in cold water for at least 30 minutes (or up to overnight in the refrigerator). This critical step removes excess starch that would otherwise prevent crispiness. After soaking, thoroughly pat them completely dry with paper towels or a clean kitchen towel. Any residual moisture will create steam in the oven, resulting in soggy rather than crispy sweet potato fries.

Space is Key
Never crowd your baked sweet potato fries on the baking sheet. Each fry needs space around it for hot air to circulate and moisture to escape. Use two baking sheets if necessary, arranging the fries in a single layer with space between each piece. Overcrowding leads to steaming rather than roasting, which is the enemy of crispiness. Halfway through baking, flip each fry and rotate your baking sheets to ensure even browning.

Instructions

Step 1: Prepare the Sweet Potatoes
Preheat your oven to 425°F (220°C) and position racks in the upper and lower thirds. Wash and scrub the sweet potatoes thoroughly, leaving the skin on for extra nutrition and texture. Using a sharp knife, cut each potato in half lengthwise, then into ¼-inch thick planks, and finally into sticks of equal thickness. Place the cut sweet potatoes in a large bowl of cold water and let them soak for at least 30 minutes to remove excess starch.

Step 2: Dry and Season
Drain the sweet potatoes and pat them completely dry with paper towels or a clean kitchen towel. Any moisture left will prevent them from crisping properly. Transfer the dried fries to a large bowl and sprinkle with cornstarch, tossing until lightly coated. The cornstarch creates a thin barrier that helps achieve crispiness. In a small bowl, combine the garlic powder, paprika, salt, black pepper, and cayenne (if using). Drizzle the oil over the fries and toss to coat evenly, then sprinkle with the seasoning mixture and toss again until every piece is well seasoned.

Step 3: Arrange and Bake
Line two baking sheets with parchment paper for easy cleanup and better browning. Arrange the seasoned sweet potato fries in a single layer, making sure they don’t touch or overlap. This space allows hot air to circulate around each fry, promoting crispness instead of steaming. Place the baking sheets in the preheated oven and bake for 15 minutes, then remove and carefully flip each fry with a spatula. Return to the oven, switching the position of the baking sheets, and bake for another 10-15 minutes until the edges are crispy and slightly browned.

Step 4: Final Crisping and Serving
When the Crispy Oven Baked Sweet Potato Fries look done, turn off the oven but leave the fries inside with the door slightly ajar for about 5 minutes. This final step allows excess moisture to escape and helps them reach maximum crispiness. Transfer to a serving plate, sprinkle with a little extra salt if desired, and serve immediately while hot and crispy. For best flavor and texture, enjoy them right away – these fries wait for no one!

Variations

Spicy Southwest Fries
Transform your Crispy Oven Baked Sweet Potato Fries into a zesty treat by adding 1 teaspoon of cumin, ½ teaspoon of chili powder, and a pinch of cayenne to the seasoning mix. After baking, toss with 2 tablespoons of finely chopped cilantro and serve with a lime-spiked sour cream or guacamole for dipping. This variation adds a Mexican-inspired kick that pairs beautifully with tacos or grilled meats.

Herb and Parmesan Fries
For an Italian twist, add 1 teaspoon of dried Italian herbs to your seasoning mixture before baking. When the sweet potato fries are fresh out of the oven, immediately sprinkle with 3 tablespoons of finely grated Parmesan cheese and 1 tablespoon of freshly chopped parsley. The residual heat will slightly melt the cheese, creating a savory coating that complements the sweet potatoes’ natural flavor. These herb-infused sweet potato fries make an excellent accompaniment to grilled chicken or fish.

Cinnamon Sugar Dessert Fries
For a sweet treat, skip the savory spices altogether and instead toss your sweet potato fries with just oil, cornstarch, and a pinch of salt before baking. When they’re crispy and hot from the oven, toss with a mixture of 2 tablespoons of granulated sugar and 1 teaspoon of cinnamon. Serve as a unique dessert with a vanilla yogurt dipping sauce for an unexpected finale to your meal.

Storage and Serving

Crispy Oven Baked Sweet Potato Fries are at their absolute best when served fresh from the oven, as they tend to lose their crispiness over time. If you do have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, avoid the microwave which will make them soggy. Instead, place them on a baking sheet in a preheated 400°F (200°C) oven for 5-7 minutes until heated through and re-crisped.

For the perfect serving experience, pair these fries with complementary dipping sauces. A sriracha mayo adds a spicy kick – simply mix ¼ cup mayonnaise with 1-2 teaspoons sriracha to taste. For a healthier option, try a Greek yogurt-based sauce with lemon and herbs. Mix ½ cup Greek yogurt with 1 tablespoon lemon juice, 1 minced garlic clove, and 1 tablespoon chopped fresh herbs.

These versatile fries make an excellent side dish for burgers, sandwiches, or grilled proteins. For a more substantial meal, top the sweet potato fries with black beans, cheese, avocado, and salsa for loaded sweet potato nachos. They also work beautifully as part of a varied appetizer spread when entertaining.

FAQs

Why aren’t my sweet potato fries getting crispy?
The most common culprits are moisture and overcrowding. Make sure to thoroughly dry the fries after soaking, coat them lightly with cornstarch, and arrange them with plenty of space on the baking sheet. Also, cutting them too thick can prevent crispiness – aim for ¼-inch thickness for best results.

Can I make these sweet potato fries ahead of time?
While they’re best served immediately, you can prep ahead by cutting the sweet potatoes and soaking them in water in the refrigerator for up to 24 hours. Drain, dry thoroughly, and proceed with the recipe when ready to bake.

Are these sweet potato fries healthy?
Yes! Crispy Oven Baked Sweet Potato Fries are significantly healthier than deep-fried versions. Sweet potatoes themselves are rich in vitamin A, fiber, and antioxidants. This recipe uses minimal oil and baking rather than frying, making it a nutritious alternative to traditional french fries.

Can I make these fries without oil?
While some oil is necessary for crispiness, you can reduce the amount to 1 tablespoon. Using an oil sprayer helps distribute a minimal amount evenly. However, eliminating oil completely will result in dry, less crispy fries.

Can I use an air fryer instead of an oven?
Absolutely! Air fryers work excellently for Crispy Oven Baked Sweet Potato Fries. Prepare them as directed, then air fry at 380°F (193°C) for about 12-15 minutes, shaking the basket halfway through. You may need to work in batches depending on your air fryer’s capacity.
