Sweet potatoes are packed with nutrients and they are naturally sweet. But the brown sugar and cinnamon we add here really amps-up the sweetness.
6 pounds (6-8) sweet potatoes, washed
¼ cup olive oil
4 tablespoons cornstarch
2 teaspoons kosher salt
1 tablespoon firmly packed brown sugar
1 teaspoon ground cinnamon
½ teaspoon cayenne pepper
-
Preheat the oven to 425°F.
-
Line 2 baking sheets with parchment paper, and spray with cooking spray.
-
Roughly peel the potatoes and cut them into ¼-inch sticks. (Some skin on the potatoes is fine.)
-
Place the fries in a large bowl and add the olive oil. Toss to lightly coat.
-
Divide the fries between the two pans in a single layer for even baking.
-
Sprinkle the cornstarch over the fries and roll around a little to try to coat evenly.
-
Sprinkle the fries with the salt and place the pans in the oven.
-
Using the center and bottom racks, bake for 20 minutes. (The top rack is too close to the heating element and could burn the fries before they finish cooking.)
-
In a small bowl, mix the brown sugar, cinnamon, and cayenne
pepper.
-
Flip the fries over, and reverse the pans on the oven racks.
-
Bake for 10-15 more minutes, keeping a close watch as they can burn easily. Remove the fries from the heat when they have a matte, crispy finish and the edges are slightly charred.
-
Sprinkle the fries immediately with the brown sugar mixture, and serve warm.
To enhance browning of your fries, pat the sweet potatoes dry before baking.
