Creamy homemade make-ahead mashed potatoes served in a white casserole dish.

Introduction

Want a way to make Thanksgiving a little less stressful when several dishes are fighting for space on the stovetop? Let me introduce you to my Make-Ahead Mashed Potatoes.

They have all the homemade flavor and creamy goodness you expect from traditional mashed potatoes, but with one big advantage: You make them the night before, refrigerate them, and pop them in the oven about 45 minutes before serving. Now that’s one less thing to worry about on Thanksgiving Day!

The South loves its mashed potatoes. If you were born and raised in the South, chances are mashed potatoes were among the first soft foods you were introduced to as a baby at the family table. I’m pretty certain that’s when homemade, creamy mashed potatoes were first imprinted on my taste buds!

The South can’t claim to have invented mashed potatoes, but we certainly have a special place for them in our hearts. They are a classic comfort food, often served alongside hearty meals with plenty of gravy and always welcome at holiday gatherings and family dinners.

Mashed Potatoes Made Easy

Homemade mashed potatoes are simple comfort food at their best. Mash the cooked potatoes until smooth and creamy, then blend with butter, milk or cream, and seasonings to bring out their full flavor.

A few simple steps make all the difference when preparing a good batch of mashed potatoes.

Key Things to Remember:

  • Choose the Right Potatoes: Russet and Yukon Gold potatoes are two popular choices. Russets produce a light, fluffy texture, while Yukon Golds make a naturally creamy mash.
  • Cut Evenly: Cut your potatoes into evenly sized pieces so they cook at about the same rate.
  • Don’t Overcook: Cook until fork-tender. You want them soft enough to mash easily without becoming waterlogged.
  • Warm Your Ingredients: Warm the milk or cream and butter before adding them to the potatoes. This helps keep the potatoes hot and makes blending easier.
  • Season to Taste: Don’t be too cautious with the salt and pepper. Taste as you go and adjust until the flavor is just right.
  • Add a Little Extra Creaminess: Butter adds richness, while milk or cream gives the potatoes a smooth texture. Sour cream and cream cheese can add even more richness and flavor.

Ingredients

  • 5 lbs Russet potatoes
  • 6 oz cream cheese
  • 1 8 oz container of sour cream
  • ¾ cup butter (1 ½ sticks) 1 stick for potatoes and 4 tablespoons melted for top of potatoes.
  • ½ cup whole milk
  • 2 tsp garlic salt
  • Paprika or chopped fresh parsley for garnish (optional)

Instructions

  • Prepare oven and baking dish: Preheat oven to 325℉. Grease a 13×9 inch or 3-quart baking dish with cooking spray or butter.
  • Peel and cut potatoes: Peel the potatoes and cut them into 1-inch cubes, ensuring that the pieces are consistent in size.
  • Boil potatoes: In a large saucepan, boil the potatoes in salted water until they are fork-tender, about 15-20 minutes. Drain the potatoes and return them to the saucepan. Using a hand-held potato masher, mash the potatoes until most of the lumps are gone.
  • Mix Potatoes: While the potatoes are still hot, add the cream cheese along with the next four ingredients. Beat at medium speed with an electric hand mixer until smooth and fluffy, being careful not to overbeat.
    Tip: I like my cream cheese and butter at room temperature and my milk warm before combining them with the hot potatoes.
  • Remove potatoes to a baking dish: Spoon potato mixture into a lightly greased 13×9 or 3-quart baking dish.
  • Brush potatoes with melted butter. If desired, sprinkle with paprika. Cover and chill in the refrigerator for up to 24 hours. When ready to bake, remove from the refrigerator and let stand at room temperature for 30 minutes before placing in the preheated oven..
  • Cover with aluminum foil and bake at 325°F for 40 to 45 minutes, or until it is thoroughly heated.

Do not overmix; this will release too much starch, and the potatoes will become pasty.

    Tip: For the most even cooking, start potatoes in cold water and bring to a boil. This ensures the inside and outside cook evenly.

        Tips for Successful Mashed Potatoes

        Even a simple dish like mashed potatoes can have a few surprises along the way. Here are some helpful tips to keep your potatoes creamy and delicious.

        • Watch the Starch: Potatoes contain starch, and overmixing releases too much of it. This can leave you with a sticky, gluey texture. Mix just until the potatoes are smooth and creamy.
        • Choose Your Mashing Method: A basic handheld potato masher and an electric hand mixer are two popular choices. Both work well, but be careful not to overmix either.
        • Gluey Texture: If your potatoes have become gluey, you have most likely overmixed them. Adding a little warm cream or milk may help with consistency, although it won’t completely reverse the texture.
        • Lumpy Texture: This usually means the potatoes weren’t cooked long enough or weren’t mashed thoroughly. A potato ricer can help smooth out lumps in cooked potatoes.
        • Watery Texture: Too much liquid may be the culprit. Try gently heating the potatoes in a saucepan over low heat to evaporate some of the excess moisture. You can also add a small amount of instant potato flakes to thicken them. No one will be the wiser!

        A Little Mashed Potato Lesson I Learned the Hard Way!

        I have to confess that one Thanksgiving I overwhipped a huge pot of mashed potatoes with my electric hand mixer. I thought it would save time, and it did, but those potatoes could have doubled as wallpaper paste! They were that gluey.

        For a long time, I blamed the potatoes. Maybe they were the wrong kind, or perhaps they were old. Eventually, I learned the real culprit was me. I had overmixed them!

        Now I make my mashed potatoes with a little more reverence.

        Did those potatoes get eaten that Thanksgiving? Yes, but there were two spoons next to the dish: one to dip with and another to scrape the potatoes off the dipping spoon!

        For a while, I thought my gravy had been the biggest hit of the holiday. That is, until someone told me the potatoes were just fine once you got the right amount of gravy on them!

        Making mashed potatoes is easy, and preparing them the night before makes holiday cooking that much more manageable. With a little planning and a few helpful tips, you’ll be ready to serve creamy, homemade mashed potatoes without the last-minute rush.

        So grab that bag of Russet potatoes, and I’ll get the big pot. We have some potatoes to peel!

        I hope you and your family enjoy this recipe and that it earns a place in your holiday recipe box.

        I’ll admit that it took me a while to figure out how to manage the stress of holiday cooking. Once I started sorting out which dishes I could prepare ahead of time, everything became easier. The stress became manageable, and holiday cooking became enjoyable again.

        Last year, I wrote a Kitchen Confidence Series post called: Survive Holiday Cooking: A Guide to Master the Madness. I hope you’ll stop by and take a look. Maybe some of the helpful tips might make your holiday cooking a little easier, too!
