If you don’t have already cooked sweet potato here’s how to prep them. Pierce 2-3 sweet potatoes a few times with a fork and place on a parchment paper-lined baking sheet. Bake in a 400-degree F oven for 40-50 minutes, or until a knife can easily poke through the center. After the sweet potato cools slightly, cut it in half, and then mash the tender orange flesh from the sweet potato for the recipe!
