First, start by preheating the oven to 425 degrees F, then line the baking sheet with parchment paper.
Scrub and rinse the sweet potatoes then dry them using a paper towel.
Using a fork, prick the sweet potatoes all over and place them on the baking sheet. Place the baking sheet in the oven and bake for 50 minutes to an hour, or until a knife inserted in the thickest part of the potato goes in without resistance.
Let the potatoes cool down a bit then slice down the middle and enjoy!
Notes
You could also cool the sweet potatoes completely them peel them and mash them for a delicious sweet potato casserole.
