Sweet potatoes have more sugar and moisture than russets, which is why homemade sweet potato fries so often turn out soft. Three things help: a light dusting of cornstarch to absorb surface moisture, a hot 425°F oven, and plenty of space on the pan so the fries roast instead of steam. A little smoked paprika plays up their natural sweetness.
They are a colorful side for a juicy turkey burger. For classic potatoes in the oven, see our crispy oven fries.
Instructions
- Heat the oven. Heat the oven to 425°F with racks in the upper and lower thirds. Line two rimmed baking sheets with parchment.
- Cut the fries. Peel the sweet potatoes if you like. Cut into sticks about ¼ to ⅓ inch thick, keeping them even.
- Dry them. Pat the cut potatoes dry with a towel. Removing surface moisture is key to crisp edges.
- Coat with cornstarch. Toss the potatoes with the cornstarch in a large bowl or zip-top bag until lightly and evenly coated, with no dry clumps.
- Add oil and spices. Drizzle with oil and toss to coat, then sprinkle with salt, paprika, garlic powder, pepper and cayenne and toss again.
- Spread out. Divide between the two pans in a single layer with space between each fry. Crowded fries steam and go soft.
- Roast. Bake for 15 minutes, then flip the fries and swap the pans between racks. Bake 10 to 15 minutes more, until browned at the edges and tender inside.
- Rest and season. Let the fries sit on the hot pans for 3 to 5 minutes to firm up, then sprinkle with a little more salt and serve.
Tips for Success
- Use two pans. Giving fries room is the single biggest factor in getting them crisp.
- Thinner is crispier. Very thick wedges will be tender but not crunchy.
- Watch the last few minutes. The natural sugars brown quickly, so check early to avoid burnt tips.
- Try a dip. Sweet potato fries go well with smoky, spicy or garlicky mayo-based sauces.
