Fast-food fries cooked at high temperatures often contain unhealthy trans fats. Sweet potato fries, however, offer a much healthier alternative. The sweet potato contains high levels of vitamins A and C, iron, potassium, fiber and four times the daily recommended allowance of beta-carotene. When baked, the starch in sweet potatoes breaks down to maltose and other soluble sugars. One serving of sweet potato fries contains only 93.8 calories and 1.2 grams of fat, and provides 1.5 grams of protein and 2.9 grams of fiber.
Preheat the oven to 400 degrees F.
Peel the sweet potatoes and cut into 1-inch wide strips using a sharp knife. Place the strips in a shallow bowl or dish.
Add the olive oil, sea salt and ground black pepper to the dish with the sweet potatoes. Toss the sweet potato strips to coat thoroughly in the oil and spices.
Transfer the coated sweet potato fries to a large cookie sheet or baking pan. Sprinkle with the nutmeg and thyme, and place the pan in the oven.
Bake the sweet potato fries for 30 to 35 minutes, or until fork-tender. Remove from the oven, allow to cool for 10 to 15 minutes, and serve immediately.
