These Baked Mashed Potatoes are my family’s favorite. My kids actually prefer these over fresh potatoes (and to be honest, so do I).
They are packed with flavor, thick enough to withstand your heartiest of gravies…yet they have a creamy flavor and can stand on their own plain!
How to make Baked Mashed Potatoes
Preheat oven to 350 degrees F.
Start with a box of Instant Mashed Potatoes. Follow the directions to make 12 servings. This is enough for a 13×9 baking dish. If you want to half the recipe or double the recipe, just adjust the ingredients, not the baking time below.
One note on making the instant potatoes. Make them a little thicker than normal. I usually pour in some extra flakes to make them thick, stirring as I add extra potatoes.
Also, make them in a saucepan one size larger than you think you need. This way you can add the other ingredients without having to dirty a mixing bowl,
Next, add sour cream, cream cheese, salt and pepper, and paprika to your potatoes. Stir until smooth and cream cheese is melted.
One trick is to cube your cream cheese before adding it to the hot potatoes, as the smaller chunks melt quicker. Or soften your cream cheese first.
Once blended smooth, pour potatoes into a buttered 13 x 9 baking dish. Slice 1/4 cup unsalted butter and place thin slices over the top of the potatoes. Sprinkle with a few pinches of paprika.
Bake uncovered in preheated oven for 30-40 minutes, until bubbly and browned on edges. Serve immediately.
Can mashed potatoes be made in advance
Yes. One of the best parts of this dish, is that you can prep it the day before. Cover with foil and refrigerate.
Then, bake accordingly when ready to serve, adding an extra 5-10 minutes if it’s coming cold from the refrigerator.
How to make Loaded Mashed Potatoes
A few years ago I shared my mother in law’s recipe for mashed potatoes. We call them Jill’s Cheating Potatoes.
If you’re looking to load them up today, you’ll need shredded cheddar cheese, bacon crumbles, and green onion.
Add these ingredients to the top of your prepped mashed potato casserole and bake according to the directions below.
I usually make them loaded when my older kids are home for the holidays!
How to make this Baked Mashed Potatoes Recipe using real potatoes
Okay. I know some of you will ask. How do I make this if I don’t want to use instant potatoes.
Easy. Add your washed, peeled potatoes to a large pot covered with water. I would say about 12 potatoes, depending on size. You’ll want about 6 cups of mashed potatoes (each medium potato usually yields 1/2 cup of mashed potatoes.
Bring to a boil over high heat. Once boiling, cook until tender. Drain the water and mash the potatoes (I like to use my mixer to get them extra creamy and smooth). Then follow the directions above using the mashed potatoes for the instant potatoes.
