Notes

Storage and Reheating 
Let the dish cool completely before storage. Transfer leftovers into an airtight container and store in the refrigerator for up to 4 days. You can also freeze portions of the potato casserole in freezer-safe containers for up to 3 months.
You can reheat portions in the oven at the same oven temperature used for baking (best for texture) or in the microwave (if you’re short on time) until hot throughout. If it’s too dry, add milk, cream, or water to restore creaminess.
