What's a Yam?

Generally, in the United States, orange-flesh sweet potatoes are labeled yams while the pale variety, with light yellow skin and flesh, are labeled sweet potatoes. However, vegetables sold as yams in one market may be sold as sweet potatoes in another. Fortunately, yams and sweet potatoes can be used interchangeably, and both are considered superfoods by nutrition experts.

How to Select and Store Yams

Yams (that is, orange-flesh sweet potatoes) are available year-round, but their peak season is winter. When purchasing, look for small to medium yams that are smooth, firm, and free of soft spots. Store whole, unpeeled yams in a cool, dry place for up to 1 week. Do not refrigerate yams, as they can dry out.

Tip: One pound yams equals about 2 medium yams or 2-3/4 cups cubed.

Ways to Prepare Yams

Yams can be used in many ways. For side dishes, they're often boiled or baked (peeled or unpeeled). They can be added to soups, stews, and braises. Sometimes boiled yams are mashed to serve as a side dish or for use an ingredient in quick breads and pies.

How to Mash Boiled Yams

  • To mash yams to use in recipes, mash the boiled yams with a potato masher or electric mixer on low speed. Measure the amount you need for the recipe. Note that 2 medium yams yield about 1-1/3 cups peeled, cooked, and mashed yams.

Tip: In a pinch, you can use canned sweet potatoes for recipes that call for boiled and mashed yams or sweet potatoes. For 2 cups mashed yams or sweet potatoes, drain one 17.2-ounce can whole sweet potatoes, if necessary, and transfer to a medium mixing bowl. Mash with a potato masher or electric mixer on low speed. Measure the amount needed for the recipe.

How to Make Yam Oven Fries

Here's how to make yam fries in your oven for a more colorful, tasty, and nutritious alternative to regular french fries.

  • Preheat the oven to 400 degrees F.
  • Scrub the yams thoroughly with a brush, then pat dry. Peel the yams if you like, or leave the skins on.
  • Use a sharp thin-blade knife to cut the yams into 1/4- to 1/2-inch-thick strips.

Tip: Cut each fry to an even thickness. Because yams contain more sugar than regular potatoes, they tend to burn easily and cook unevenly if cut too thin.

  • Toss the yams with olive oil and any desired seasonings (fresh or dried sage, rosemary, and thyme work especially well with yams).
  • Arrange yams in a baking pan. Be sure your baking pan is large enough to bake the yam slices in a single layer so they brown evenly.
  • Bake the yams for 20 to 30 minutes until tender, turning once.
