Make-Ahead Creamy Cheesy Mashed Potatoes

These cheesy mashed potatoes are sinfully good and I’ve made them for large crowds as well as smaller batches for just the two of us. I made them for Annie’s Backyard Wedding and I’ve made them several times for holiday meals.

This is a make-ahead recipe that makes entertaining or just having a side for dinner in the freezer, a breeze.

Ingredients

  • 5 lbs russet potatoes
  • 4 oz. cream cheese, room temperature
  • 1/2 cup sour cream
  • 1/2 cup milk
  • 1/4 cup butter
  • 1 egg, lightly beaten
  • 2 tsp salt
  • 1 tsp pepper
  • 1/3 cup onion
  • 1 cup cheddar cheese
  • extra cheddar cheese (optional)

Instructions

  • Peel potatoes and quarter. Add to stock pot. Cover with water. Bring to a boil and cook for 25 minutes or until fork tender. Drain into a colander.
  • Put drained potatoes in a large bowl. Add the sour cream, cream cheese, milk butter, salt and pepper. With a hand mixer, beat until almost smooth. Add the egg and beat a bit more until smooth. I add the egg last because I'm afraid of it cooking if added right away to the hot potatoes. Lastly, stir in the cheddar cheese and onions until well combined.
  • Scoop potatoes into a casserole dish or smaller freezer-baking-safe dishes sprayed with cooking spray (PAM). I sometimes use aluminum loaf pans.
  • Preheat oven to 375° when you're ready to bake. If you so desire you can add some more cheddar cheese to the top of the potatoes before you bake.
    Bake for 35-40 minutes or until heated through.
  • If you are using frozen, be sure to let thaw completely before baking.

Notes

This recipe is one that I typically make ahead and put in the refrigerator 1 – 2 days before I’m going to serve it. Once I put it into a casserole dish I cover it tightly with plastic wrap (I love press-n-seal). Then I take it out of the refrigerator and let it get to room temperature before I bake it.

The Potatoes

I really like to use russet potatoes for mashed potatoes because they don’t get too mushy when you mash them. When your adding all of the ingredients that I do, it takes a bit of mixing to blend it all.

Some people like Yukon gold potatoes for mashed potatoes and you can definitely use any type of potato that you prefer.

Make-Ahead Meal

I use this recipe for make-ahead meals. When I make my meatloaf I also make the 5 lb recipe of these potatoes. I divide the meatloaf mix into three loaves and the potatoes into three loaf pans. We pop one set in the oven and freeze the others for quick weeknight pre-made meals.

Scaling the Recipe

I make this recipe for a crowd often but I double everything except the milk. I use almost 1 cup. I start with 1/2 a cup but add more if needed. It will take more time to cook through when you double the recipe.

If I want to make less use the following:

  • 3 lbs of potatoes
  • 4 oz. of cream cheese
  • 1/4 cup of sour cream
  • 1/4 cup of butter
  • 1/4 cup of milk
  • 1 tsp salt
  • 1/2 tsp of pepper
  • 1 egg
  • 1/4 cup of onions
  • 1 egg

Follow the directions above. It may take a bit less time to heat through

We made it for Annie’s Backyard Wedding and we served it with Filet and Lobster, Steamed Asparagus with Hollandaise Sauce, and Caesar Salad.

I also make this for holiday dinners. It’s great to make the day before and then just pop it in the oven 1 hour before dinner will be served.

I hope you like this recipe!

Enjoy,
