How to make mashed potato casserole:
Place potatoes in a large stockpot and cover with water. Add about a ½ teaspoon of salt to the water and bring to a boil.
Reduce heat to simmer and cook until potatoes are tender. This should take about 15 minutes. Drain the potatoes and return to the pot.
Add the sour cream, cream cheese, 2 tablespoons butter, milk, salt and pepper to the potatoes. Then beat with an electric hand mixer until smooth and creamy.
Spread potatoes into a greased 13×9-inch baking or casserole dish. Cover and store in the refrigerator until ready to bake (up to 2 days). Or bake right away!
When you're ready to bake, brush the top of the potatoes with 1 tablespoon melted butter and sprinkle with a bit of Spanish paprika.
Bake, uncovered, in a 350°F oven for about 30 minutes or until bubbly.

Can you freeze mashed potatoes?
You absolutely can! However, frozen mashed potatoes can tend to get a grainy texture. So, to ensure your potatoes stay creamy be sure to add enough fat/butter or cream to coat the potato molecules. This is the key to successful frozen mashed potatoes.
When ready to bake, thaw in the refrigerator overnight. Brush the top with 1 tablespoon melted butter and sprinkle with paprika. Preheat your oven, and bake at 350 degrees, uncovered, 30 minutes or until bubbly.
If you have any leftovers, you can store your leftovers in the fridge for up to 4 days.
