The Best Make-Ahead Mashed Potatoes

I can still picture it: Thanksgiving at my grandmother’s house, the aroma of roasting turkey filling every corner. But above all the other incredible dishes, it was her mashed potatoes I craved most. They weren’t just sustenance; they were a warm, creamy hug on a plate, a testament to love and tradition. Trying to replicate that magic in my own kitchen has led me down many paths, but this recipe? This is the one that finally captures that same comforting essence, and even better, it lets me prep ahead so I can actually enjoy the holiday!

Recipe Overview

Prep Time: 15 minutes
Cook Time: 46 minutes
Total Time: 1 hour 1 minute
Servings: 8-10
Yield: About 8-10 servings
Dietary Type: Vegetarian

Ingredients

5 lbs russet potatoes, scrubbed and poked several times with a fork
3 cups heavy cream, hot
8 tablespoons unsalted butter, melted
2 teaspoons salt, add more to taste
Black pepper, to taste (optional)

Equipment Needed

Microwave
Oven
Large microwave-safe bowl
Fork, masher, or spatula
Mixer (stand mixer preferred, hand mixer acceptable)
Plastic wrap

Instructions

Adjust an oven rack to the middle position and preheat the oven to 450 degrees Fahrenheit.
Microwave the potatoes on high for 16 minutes, turning them over once halfway through the cooking time. This jump-starts the cooking process and reduces the oven time.
Transfer the potatoes directly onto the oven rack. Bake for about 30 minutes, turning them once, or until a skewer glides easily through the flesh. This roasting method intensifies the potato flavor and gives the mashed potatoes a depth you simply can’t achieve by boiling.
Remove the potatoes from the oven and cut each potato in half lengthwise. The potatoes will be very hot, so be careful!
Using an oven mitt or folded kitchen towel to hold the hot potatoes, scrape out the flesh into a large microwave-safe bowl. Discard the skins (or save them for potato skins!).
Using a fork, masher, or spatula, break the potato flesh into small pieces. Don’t overwork them at this stage; just break them down enough to make them manageable for the next step.
Transfer half of the potatoes to a mixer bowl. If you have a stand mixer, use it with the paddle attachment. Otherwise, a hand mixer with standard beaters will work, though a stand mixer will give you the best results. Beat on high speed until smooth, about 30 seconds.
Gradually add the rest of the potatoes to the mixer bowl and continue to incorporate them until no lumps remain, about 1 to 2 minutes. Be patient and scrape down the sides of the bowl as needed to ensure everything is evenly combined.
Remove the bowl from the mixer and gently fold in 2 cups of the hot heavy cream followed by the 8 tablespoons of melted butter and 2 teaspoons of salt. At first, this mixture will appear quite wet, but don’t worry! Keep folding, and it will all come together beautifully without becoming soupy.
Fold in up to 1/2 cup more cream as needed to reach your desired consistency. Some people prefer their mashed potatoes thicker, while others like them lighter and fluffier – this is your chance to customize them to your liking.
Once you’ve reached your desired consistency, fold in an additional 1/2 cup cream. The potatoes will be quite loose at this point, but this extra moisture is essential to prevent them from drying out if you’re making them ahead of time. If you’re serving the potatoes immediately, you can skip this step.
Add any additional seasonings you desire. Black pepper is a classic, but I also love adding a touch of Parmesan cheese and some roasted garlic for extra depth of flavor. Get creative and experiment with your favorite herbs and spices!
TO STORE: Transfer the potatoes back to the large microwave-safe bowl and cover tightly with plastic wrap. Refrigerate for up to 2 days.
TO SERVE: Poke lots of holes in the plastic wrap (this prevents explosions in the microwave!) and microwave at 75% power until the potatoes are hot, about 14 minutes, stirring gently halfway through. The lower power setting helps to prevent the potatoes from becoming dry or rubbery.

Expert Tips & Tricks

Roasting is Key: Don’t skip the roasting step! It’s what sets these mashed potatoes apart and gives them that incredible flavor.
Hot Cream is Essential: Using hot cream helps to keep the potatoes light and fluffy. Cold cream can cause them to become gluey.
Don’t Overmix: Overmixing the potatoes will release too much starch and make them gummy. Be gentle and fold in the cream and butter until just combined.
Taste as You Go: Don’t be afraid to taste and adjust the seasoning as you go. Salt is crucial for bringing out the flavor of the potatoes, so don’t be shy with it!
Make it Your Own: Feel free to experiment with different flavors and add-ins. Roasted garlic, herbs, cheeses, and spices can all add a unique twist to your mashed potatoes.

Serving & Storage Suggestions

Serve these mashed potatoes hot as a side dish with your favorite protein, such as roasted chicken, steak, or pork. They are also a delicious addition to holiday meals like Thanksgiving and Christmas.

Store leftover mashed potatoes in an airtight container in the refrigerator for up to 3 days. To reheat, microwave on low power, stirring occasionally, until heated through. You can also reheat them in a saucepan over low heat, adding a splash of milk or cream if needed to restore their creamy texture. Freezing is not recommended as the texture can change significantly.

Variations & Substitutions

Dairy-Free: Substitute the heavy cream with full-fat coconut milk and the butter with vegan butter or olive oil.
Garlic Mashed Potatoes: Roast a head of garlic and mash the cloves into the potatoes along with the cream and butter.
Cheesy Mashed Potatoes: Stir in shredded cheddar, Gruyere, or Parmesan cheese for a cheesy twist.
Herb Mashed Potatoes: Add chopped fresh herbs like chives, parsley, or thyme to the potatoes for a burst of flavor.
Loaded Mashed Potatoes: Top the mashed potatoes with crumbled bacon, shredded cheese, sour cream, and chives for a decadent treat.
Sweet Potato Mash: For a sweeter variation, use sweet potatoes instead of russet potatoes. The cooking time will be similar.

FAQs (Frequently Asked Questions)

Q: Can I use a different type of potato?
A: While russet potatoes are recommended for their fluffy texture, you can use Yukon Gold potatoes for a slightly creamier result. Avoid using waxy potatoes like red potatoes, as they can become gummy when mashed.

Q: Can I make these potatoes ahead of time and freeze them?
A: Freezing mashed potatoes is not recommended, as the texture can change and become grainy. It’s best to make them no more than 2 days in advance and store them in the refrigerator.

Q: What if my mashed potatoes are too thick?
A: Simply add a little more hot cream or milk until you reach your desired consistency. Be careful not to add too much liquid, or the potatoes may become soupy.

Q: How do I prevent my mashed potatoes from becoming gluey?
A: Avoid overmixing the potatoes, and use hot cream instead of cold. Also, don’t use a blender or food processor, as these can overwork the potatoes and release too much starch.

Q: Can I use salted butter instead of unsalted butter?
A: You can, but be sure to adjust the amount of salt you add to the recipe accordingly. Taste as you go and add salt until the potatoes are seasoned to your liking.
