Creamy Oven Baked Mashed Potatoes

These Creamy Oven Baked Mashed Potatoes are so simple to make, and I’m including make ahead instructions here too!

What makes these creamy?  Additions of cream cheese, sour cream and butter make these Oven Baked Mashed Potatoes so smooth and creamy and rich.  Everyone loves these, and they’re always a bit hit.  You can lighten up the recipe a bit by using low fat cream cheese and light sour cream, but I recommend you go all out and use the good stuff!

How to Make Creamy Oven Baked Mashed Potatoes:

The potatoes are boiled until quite soft.  Mash, and then mix in cream cheese, sour cream and garlic salt.  That’s it!  Then spoon the mashed potatoes into a buttered casserole dish and dot with pieces of butter.  Garnish with chopped chives and a sprinkle of paprika.  Bake for 15 minutes.  Or make them ahead and bake them when you’re ready for them!

Are there Make Ahead instructions for these Mashed Potatoes?

I like to make these potatoes ahead of time and keep them in the refrigerator. Prepare the recipe and place the potatoes in a casserole dish with garnishes on top. Cover with plastic wrap and refrigerate until ready to heat. Remove from the refrigerator and let it sit at room temperature for at least an hour before baking. Remove plastic wrap, and bake as directed.  If you’re lacking oven space, use your slow cooker to heat up the potatoes instead!

How to Make Perfect Mashed Potatoes

I also have a step-by-step tutorial on How to Make the Best Mashed Potatoes, if you’re interested in checking that out.  I think they turn out perfect, but they’re not quite as creamy as my Creamy Oven Baked Mashed Potatoes since there is not cream cheese or sour cream in that one.

      If it’s a deep one– a little larger than 13×9 would be best if you have one!

    I made these potatoes for Christmas dinner and they were a hit! I added extra butter/ margarine and only had a little sour cream in house so I added some half and half. Awesome! I will definitely fix again.

    Love mashed potatoes baked in the oven. It’s also yummy if you add some parmesan or gruyere.
