Recipe: Roasted Sweet Potatoes

Yield: Serves 4

Sweet potatoes are a true nutritional powerhouse food. They are supercharged with nutrients like potassium, magnesium, manganese, copper, vitamin C, vitamin B6, pantothenic acid, niacin, thiamin and riboflavin. In addition, orange-fleshed sweet potatoes are one of the best food sources of beta-carotene. The thyme this recipe calls for contains health protecting thymol, rosmarinic acid and flavonoids, while basil delivers eugenol and flavonoids. This dish is considered hypoallergenic.

Did you know?

Extra-virgin olive oil loses both flavor and health benefits when it's used in dishes that require cooking at high temperatures. This recipe for roasted sweet potatoes instructs you to add the olive oil at the end of cooking for a burst of flavor and maximum health effects. You could also skip the olive oil in this recipe, but if you want to optimize the absorption of fat-soluble nutrients such as beta-carotene present in this nutrient-packed dish, don't hesitate to use olive oil.
