Preparation: Begin by generously buttering an 8 x 8 inch casserole dish. Spread the entire bag of Simply Potatoes evenly within the dish.
Sauce Creation: Over medium-high heat, combine milk, whipping cream, salt, mustard, pepper, and nutmeg in a medium saucepan. Whisk and stir until the mixture is nearly boiling.
Adding Cheese: Introduce the cheddar cheese into the saucepan, reducing the heat and stirring until the cheese melts completely.
Combining: Pour the creamy cheese mixture over the potatoes in the casserole dish. Let it cool slightly.
Final Touches: Add dots of butter slices and a sprinkle of paprika over the top. Then, cover the dish tightly with plastic wrap.
Refrigeration: Place the casserole in the refrigerator for 12 hours or overnight.
Baking: Preheat your oven to 350 degrees F. Take the refrigerated casserole out and bake it uncovered for 45 minutes.
