Mashed potatoes are a staple at all our holiday meals. I thought I’d try something a little different this year and make a yummy Mashed Potato Casserole. I think I might even like it better!

Mashed Potato Casserole

We celebrated our Thanksgiving in Canada in early October so the next big occasion is Christmas for us. I know that Americans are celebrating their Thanksgiving tomorrow so I wanted to get this recipe out just in time. 

I like mashed potatoes, but I don’t love them. This recipe, though? I’d put it in the love department. It’s a keeper and one I’ll make again and again. 

It’s fairly straightforward to make. If you are making mashed potatoes, take a few extra steps and make this easy casserole recipe. You can thank me later.

This recipe has both sour cream and cream cheese in it. I think that helps to make it so rich and creamy. 

I served it for dinner the other night and it received rave reviews. I love seeing people taking seconds of my recipes. You know you have a good recipe when that happens. 

How to Make Mashed Potato Casserole

The first step is to cook the potatoes. Boil the peeled potatoes on the stovetop for 10 minutes or until fork tender. Drain the water.

Add salt, pepper and butter. Add eggs, cream cheese and sour cream and mash to combine. 

Pour into greased 9×13 casserole dish and sprinkle with cheese. Bake for 50 minutes at 325F. 

Remove from oven and top with sliced green onions, if desired. Serve it hot with chicken, turkey or beef.

We had lots leftover and it still tasted delicious heated up the next day in the microwave. 

You could also freeze it if you wanted to make a few casseroles to save for later. I would do this if I had a freezer. Someday….
