Mashed Potato Casserole - The Southern Lady Cooks

Mashed Potato Casserole is a great recipe! We love potatoes “fixed” this way and you can do so many different variations. Great for holidays or just anytime. Every time I have ever taken this easy casserole to a gathering I have come back with an empty pan. It’s just that good!

Ingredients Needed for Mashed Potato Casserole:

Large potatoes, peeled


Butter or margarine

Cream cheese

Sour cream

Evaporated milk

Black pepper

Onion flakes

Garlic powder

Monterey Jack cheese, shredded or cheese of your choice


Recipe Notes: You could also add chopped bacon or ham, regular onions, or green onions to this dish. You can use whatever cheese your family loves. I have made it with all different kinds and it’s always a hit!
