How Long to Cook Yams in the Oven
Yams, also called sweet potatoes, take around 45-60 minutes to bake in the oven at 400 degrees. Yam cooking time varies based on size and oven temperature. To tell when your yams are done, piece them with a fork. When the fork is inserted easily and can be removed with equal ease, the yams are ready to eat. Yams are so versatile and in our favorite sweet potato casserole recipe, we both boiled and baked the yams. They were boiled for 15 to 20 minutes, mashed, and baked for an additional 25-30 minutes. It's not necessary to boil yams before baking in the oven, but they can make a delicious casserole when cooked this way. Sweet potatoes can also be made into delicious sweet potato pie.
