1 large sweet potato and 1 large russet baking potato (1 1/2 pounds total), peeled and sliced into thin strips
1/4 cup canola oil
1/2 teaspoon chili powder
1/2 teaspoon garlic powder
1/2 teaspoon ground cumin
1/2 teaspoon sea salt
Preheat the oven to 450°F.
In a bowl, toss together the potatoes, oil, chili powder, garlic powder, and cumin. Arrange the potatoes in a single layer on a baking sheet. Bake for 25 minutes. Halfway through, turn the fries over and continue baking.
Remove the fries from the oven and place them on several layers of paper towels. Sprinkle with the salt.
