Totally! These cheesy potatoes can be prepared before serving in order to save time later. This is especially great if you are serving at a holiday table like Thanksgiving or Christmas dinner! Simply prepare these potatoes according to the instructions. But instead of baking, cover with foil and place in the refrigerator until it is time to bake and serve. I recommend only prepping 1-2 days in advance! You could also fully bake this recipe a couple hours ahead of time (like Thanksgiving morning), allow to cool at room temperature, and place in the refrigerator until time to re-heat. Then cover with aluminum foil and place back in the oven at 350 degrees to warm throughout.
