These healthy oven-baked sweet potato fries are crispy at the edges and tender and sweet inside. They’re easy to make and a healthier alternative to deep-fried fries.
If you crave sweet potato fries but want a lighter version than restaurant deep-fried fries, this oven-baked method delivers great texture and flavor with less oil. Using a few simple techniques—coating the fries in a little cornstarch, choosing a high-heat oil, and baking in a single layer—produces fries that brown and crisp on the outside while remaining soft inside.
Baked sweet potato fries make a versatile side: serve them with summer grilled burgers, pile them on top of a salad, or enjoy them with your favorite dipping sauces like sriracha aioli, ketchup, or barbecue sauce. You can easily customize the seasoning to match the meal or your mood.
Ingredients You’ll Need
Use fresh, simple ingredients to make this oven-baked sweet potato fries recipe. The list below includes the basics; adjust amounts in the recipe card to serve more or fewer people.

- Sweet potatoes: about 2 medium sweet potatoes (8–10 ounces each). You can also cut them into wedges, but thinner fries crisp best.
- Cornstarch: a small amount tossed with the cut fries helps absorb surface moisture and encourages a crisp exterior without deep frying.
- Avocado oil: a high-smoke-point oil that stands up to 425°F baking. Olive oil can be used at lower heat but may smoke at higher temperatures.
- Sea salt and spices: sea salt is essential; add black pepper or spices like paprika, garlic powder, or other seasonings to taste.
How to Season Baked Sweet Potato Fries
Sweet potato fries pair well with both savory and warming spices. Try one of these blends or create your own:
- Chili powder or smoked chipotle powder for heat and smokiness
- Cinnamon and nutmeg for a sweet-warm profile
- Cajun seasoning for a bold, tangy heat
- Garam masala or curry powder for an Indian-inspired flavor
- Cumin and cayenne for earthy heat
How to Make Sweet Potato Fries
This recipe requires just a few clear steps and minimal hands-on time. Follow these tips for the best results.
Preheat the oven: set the oven to 425°F (218°C) and line a baking sheet with parchment paper.
Prep the potatoes: peel (optional) and slice sweet potatoes into 1/4 inch thick fries. Peeling helps create a more uniform, crisp exterior, though leaving the skin on is fine and adds fiber.

Place cut fries in a large bowl. Sprinkle with cornstarch, then drizzle with avocado oil and add sea salt, garlic powder, and paprika (or your chosen spices). Toss gently until each fry has a light, even coating.

Arrange the fries on the prepared sheet in a single layer with space between pieces so air can circulate and the fries can crisp. Do not crowd the pan; use two sheet pans if needed. Some recipes suggest soaking cut fries in cold water to remove excess starch, but with the cornstarch step this isn’t necessary for achieving crisp results.

Bake and serve: Bake for 20 minutes, flip the fries, then bake another 10–18 minutes or until the tips are deeply golden and slightly darkened. Exact timing varies by oven, pan type, and how thick the fries are. Serve immediately with your favorite dipping sauce.

What to Serve with Sweet Potato Fries
These sweet potato fries pair well with a wide range of mains and salads. Try them alongside pulled pork, turkey or beef burgers, ham steaks, or as a side for sandwiches. They also complement salads—toss a few on a cobb-style salad or a southwest chicken salad for texture and flavor. For a heartier meal, top fries with chili and shredded cheese for loaded sweet potato fry nachos.
Are sweet potato fries actually healthy?
Yes—especially when oven-baked. Deep-fried restaurant fries are often high in calories and saturated fat. Baking at home with a modest amount of oil reduces calories and saturated fat while preserving the sweet potato’s nutritional benefits. Sweet potatoes provide fiber, vitamin A, vitamin C, and potassium. Baking at home also avoids cross-contamination from shared fryers, which is helpful for gluten-free diets.
Storage
Sweet potato fries are best eaten right out of the oven because they lose crispness as they cool. Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, bake at 425°F for 7–10 minutes or use an air fryer at 400°F for about 5 minutes to restore crispiness.
More Delicious Sweet Potato Recipes
Sweet potatoes are versatile and nutritious. Try them in soups, pies, roasted sides, or bowls for balanced meals. Experiment with mashed or roasted sweet potatoes, sweet potato soups, shepherd’s pie with sweet potato topping, or grain bowls featuring roasted sweet potato cubes.
