Potatoes are the Ultimate Comfort Food!
Are you looking for an easy comforting side dish that can be made ahead of time? Did you know scalloped potatoes can be made ahead?
Well, they can which helps speed things up drastically on the day you are trying to get everything else ready!!
Make-Ahead Side Dish!
You can make these ahead by baking them the day before and reheating them for about 30 minutes before serving. Or you can assemble the dish and refrigerate it then bake it the day of.
Either method you choose just be sure to pull the dish from the refrigerator in plenty of time to allow it to come to room temperature or for at least a good 20 minutes before putting it in the oven.
And did you know there is actually a difference between scalloped potatoes and potatoes au gratin??? I didn’t up until recently and that is partly why I changed the recipe.
True scalloped potatoes will not have any cheese in them and au gratin will and sometimes even a breadcrumb topping. Who knew, right??
This easy side dish is perfect to serve for Easter. I know I am a bit late getting this recipe out to all of you but better late than never, lol!
