How to Make Twice Baked Potato Casserole

This Million Dollar Twice Baked Potato Casserole is quick and easy to make. Mix together mashed potatoes, cream cheese, cottage cheese, sour cream, seasonings, and cheddar cheese. Spread into a 9×13-inch baking dish and top with some more cheddar cheese and Italian bread crumbs. YUM! I sprinkled the baked casserole with some dried parsley for color.

  • I used pre-made mashed potatoes in this casserole. It is such a time saver! You can use leftover homemade mashed potatoes or make your own fresh mashed potatoes. Either way, it will taste great.
  • Feel free to swap the cheddar cheese for your favorite cheese – Swiss, Monterey jack, or Gouda would be nice. You could even add bacon to this twice baked potato casserole. I mean, everything is better with bacon! Right?!?!?!
  • Can I Make this Casserole ahead of time? I love to make this easy casserole ahead of time. I mix everything up and store it in the refrigerator until I am ready to bake. Perfect for an easy weeknight side dish or dinner party.
  • If you are baking this casserole after refrigerating, you will need to add a few minutes to the cooking time to make sure it is heated through. Cover the casserole with foil if the breadcrumbs start to get too brown.
  • Can Potato Casserole be Frozen? Absolutely! You can make this casserole in advance and freeze unbaked for later.
  • To bake after freezing,  thaw it completely and bake as directed below. We like to make the whole recipe and split it between two pans. Bake one now and freeze one for later.

  1. Are precooked potatoes the same as instant potatoes? I assume that you make the potatoes first before adding the other ingredients. Can I use ricotta cheese instead of cottage?

  2. These were a big hit at our dinner party last night. I halved the onion powder because I'm not a big onion fan. I also made my own mashed potatoes like I always do. Everyone raved over this dish. I even sent the recipe home with my guests. This one is a winner, Stephanie!!

  3. Did you use full fat cottage cheese, cream cheese & sour cream ? I always have all 3 in my frig but they are low fat (never ever non-fat). I will try it your way the 1st time.

  4. But cottage cheese??? that just doesn't sound appealing… can you leave it out or substitute heavy cream or something else?

      1. What would be a substitution if cottage cheese is absolutely off the table? Ricotta? Suggestions, please!

  5. What brand of pre cooked mashed potatoes do you use? And do you warm them before mixing them with the other ingredients? I was thinking that maybe they would mix into the other ingredients better if warmed first

    1. I used Bob Evans mashed potatoes. I didn't warm them first, but you could certainly pop them in the microwave for a minute if you prefer. Enjoy!
