1 Don't preheat the oven. 2  Prick your sweet potatoes each 2-3 time with a fork, then place them directly on the oven rack in the middle of the oven, above the foil. 3  Turn the oven on to 425. 4  Bake for 45 minutes for sweet potatoes/yams that are 2-3 inches in diameter. For super large sweet potatoes, bake for an hour and 15 minutes. 2  After the time has elapsed, don't open the oven but turn it off. 3  Let the sweet potatoes sit in the oven for at least 30 minutes but up to an hour. 4  Remove from the oven and eat immediately, or remove the skin and store in a container in the fridge.
A great way to cook them is to bake them. Bake sweet potatoes in their jackets. Wash, cut off the ends and bake in a preheated 400 degree F oven for 40 to 60 minutes (dependi â¦ ng on the size of the potatoes and how firm you want them to be).ur sweet potato cooks give some advice: 1  I usually bake a small-to medium-sized sweet potato for 40 minutes in a 350-degree oven. 2  Choose sweet potatoes about 8 oz each. 3  You could also throw it in the microwave till nearly done and finish off in the oven brushed with olive oil to crisp the skin.
