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

Salt

Butter or margarine

Cream cheese

Sour cream

Evaporated milk

Black pepper

Onion flakes

Garlic powder

Monterey Jack cheese, shredded or cheese of your choice

Paprika

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!

      1. Finally made this today for a quarantine Christmas dinner! It reminded me of twice baked potato stuffing! Awesome! And comforting!5 stars

  1. I need to make this ahead of time for Thanksgiving and freeze it. Would you recommend freezing before or after baking it? Thank you!
    ~ Janna

    1. I would bake it first, but I have never frozen this so can’t say exactly how it would turn out. I would think it would freeze okay.

  2. I served this as a side to Bang Bang Chicken. I needed a mashed potato that wasn’t boring and could stand alone. This was it. Absolutely perfect!5 stars

  3. How many people does this serve? Want to make for thanksgiving 15 people but not sure if I should double or triple the recipe

      1. I have not tried freezing it but see no reason why you couldn’t, Amanda.

  4. Thank you for not putting a bunch of needless pictures or videos or more pages to view before actually seeing the recipe itself. This is why I like your FB posts so much more than the others. I am certainly going to download and try this one.

  5. We feed the high school football team before games on Friday night. I made this, doubled the recipe, & needless to say, came home with an empty bowl.5 stars

    1. So happy to hear everyone enjoyed this recipe, Carolyn! Thank you for letting me know. That’s a lot of mashed potatoes! Have a great week ahead.

  6. I tried this a few months back, after seeing the recipe by FB. I loved it – Absolutely delicious!!! I live in Germany and all cheese types are not readily available…but cheddar is…works just fine!5 stars

  7. I had this kind of Mashed potatoes at a party in Indianapolis, IN several years ago, and believe me, it was the best mashed potatoes I ever had. Thanks Southern Lady Cooks. Very happy to finally get the recipe. LOVE IT.

    1. Hi Helen, So happy to hear from you and hope all is well. It has been a long, hot, dry summer here. I love this casserole but I love anything with potatoes. Love and hugs, Judy

  8. Is monteray jack a mild cheese or tangy coz we dont have that here in Australia so i need to find a substitute for it ?

  9. I basically make this same recipe, but mix in a beaten egg and pimentos (and the cheese) to the potatoes before baking. They puff up nicely. My mother would always fix them this way, expecially for holidays.
