Baked Crispy Sweet Potato Fries | A Couple Cooks

Most people don’t become interested in healthy eating overnight; at least we didn’t. It took a few “gateway” foods to get us interested, one of which was the sweet potato. A few meals of loaded sweet potatoes and we were hooked, not only on the potato itself, but the concept that healthy eating could be vibrant and delicious.

And what’s a more satisfying in a gateway food than fries? We’ve been searching for a no-fail baked sweet potato fry recipe for years, but it’s been hard to come by. We gave up after several failed attempts where the fries turned into a pile of mush in the oven (have you been there, too?).

We got the bug again recently and this time, they finally turned out as we’d hoped: slightly crispy on the outside, perfectly seasoned, and lusciously sweet on the inside. The trick was using a bit of cornstarch to coat the outside, then baking at a high temperature with the fries as spread out as possible.

A word of warning: don’t expect these to be crispy like standard fries; the moisture content in sweet potatoes makes it almost impossible to crisp up in the oven (unless they’re burned — been there too!). The cornstarch method helps most of the fries to become slightly crispy on the outside, but you’ll find stragglers that are soft. They’re best fresh from the oven; sitting time afterwards allows them to become mushy.

Once you’ve adjusted your expectations to the baked sweet potato fry, you’ll find they’re addicting-ly delicious: an ideal gateway into the world of whole food eating.

The tricks to this preparation are using cornstarch to give the fries a "crispy" exterior, baking at a high temperature, and keeping the fries from touching each other as much as possible while cooking. While the sweet potato doesn't crisp in the same way as the standard potato, it is possible to get relatively crispy exterior with this method. Note that the fries do become soft as they sit, so they are best served warm from the oven.
by:
Makes: 4
What You Need
  • 2 pounds sweet potatoes
  • 2 tablespoons olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon kosher salt
  • 2 teaspoons chili powder
  • 2½ tablespoons cornstarch
What To Do
  1. Preheat the oven to 425F.
  2. Wash the sweet potatoes, leaving on the skin. Slice off the ends of each potato, then slice the potato in half lengthwise. Place the potato cut side down. Slice a ¼-inch slice, then lay it on its side and it into several long strips. Repeat until all potatoes have been cut into fries. (See this video for inspiration, though our method is slightly different.) Don't worry if the pieces are uneven, but aim for as uniform of thickness as possible.
  3. Place the fries in a large bowl; drizzle with 2 tablespoons olive oil, then add 1 teaspoon garlic powder, 1 teaspoon kosher salt (less if using table salt), 2 teaspoons chili powder, and 2½ tablespoons cornstarch. Mix thoroughly to combine.
  4. Line two baking sheets with parchment paper. Spread the fries on the paper, placing them as far apart as possible.
  5. Bake 15 minutes on one side, then flip the fries and bake 10 to 15 additional minutes until the fries are dry and slightly browned; watch them carefully since the cooking time can depend on the thickness and the heat of your oven. (If the majority of the fries seem goey, continue to cook.)
  6. Cool for about 5 minutes (resist the urge to taste), then enjoy. Fries will be slightly soft, but the majority of the outsides will be crispy. Fries are best right out of the oven; they become softer as they sit.

    Mmmm I love sweet potatoes!! I actually just had them tonight with dinner, but I’m always looking for different ways to make them and incorporate them into meals. I can’t wait to try this cornstarch trick!

    my favorite sweet potato fry method is i make my boyfriend order them at restaurants and then steal all of them off of his plate because if you don’t order them yourself, the calories don’t count, amiright? (but i should probably come to terms with the lies i tell myself and make your recipe…)

    I love sweet potatoes and have suffered from many a soggy chip (from the uk so just can’t bring myself to call them fries!) so will certainly be trying this method.

    Accidentally ate all my sweet potato fries a couple of nights ago out to dinner. Oops! Just can’t resist them though! I am having trouble getting half my family on board with sweet potatoes, so will try your method at home for a healthier sweet potato fry and see if they will go for it. Maybe the extra seasonings will bring them over to the sweet potato side finally. Then again, more for me if they decline… Yum!
