Anatomy of a Sweet Potato

Think sweet potatoes belong only on the Thanksgiving table? Reach for this nutritional powerhouse year-round.

One medium-sized, baked, 141-calorie sweet potato is loaded with dietary fiber, vitamin C, 42% of the RDA of calcium, twice the RDA of vitamin A, thiamin, and the antioxidant beta carotene. It is also a great source of manganese, a trace mineral that helps keep bones strong and blood glucose levels normal. All this and zero cholesterol, too.

No wonder sweet potatoes have been a staple since pre-historic times in their native Central America. Christopher Columbus even brought a few back from his 1492 voyage to the New World.

Now widely grown, this orange-hued vegetable is a true treat: It tastes good and it's good for you.

Try this healthy, easy stew recipe, starring sweet potatoes.

Oven Beef Stew With Sweet Potatoes
Makes 8 servings (8 oz each)

  • 2 lbs lean beef stew meat, cut into bite-sized cubes (trimmed of visible fat)
  • 3 carrots, sliced (or 3 cups baby carrots)
  • 2 onions, quartered and separated
  • 3 medium-to-large sweet potatoes, cut into stew-sized wedges
  • 1 bay leaf
  • 1 tsp dried oregano flakes
  • 1/2 tsp freshly ground black pepper (add more to taste)
  • 1/2 tsp salt (optional)
  • 2 1/2 cups low-sodium beef broth (add more as necessary)
  • 11 oz can condensed tomato bisque soup

    1. Preheat oven to 275 degrees. In an oven-proof Dutch oven or large casserole pan (with lid), combine all the ingredients except the broth and soup, mixing well.

    2. In a separate bowl, blend the broth with the condensed soup and pour over the meat mixture. Cover and bake for 2 to 3 hours.

    3. Check after 2 hours to see if the meat is tender and cooked throughout. If too much liquid has evaporated, add a cup or two more of the beef broth. Stir the mixture and bake an additional 15 minutes.
