The biggest timesaver you can have for your Thanksgiving meal (and many events, holidays and even weeknight dinners) are these Make-Ahead Mashed Potatoes.
That's right, make the mashed potatoes the day before and reheat them in your slow cooker, which leaves your oven open for the rest of the feast's goodies.
And if you don't need the extra space in your oven, simply reheat them in the oven in a baking dish. But it's always nice to have the work done ahead of time.
After all, you can never have enough time. Am I right?

Ingredient Notes:
- We used a combination of Yukon Gold and Russet potatoes, but feel free to use just one if you desire.

Instructions
My favorite part of these mashed potatoes is that I can have them completely done ahead of time. Pans washed, potatoes mashed and all ready for the big day. Anything that makes dinner easy is a huge win in my book.
Peel and cube potatoes so they are all the same size. Place potatoes in a large pot and cover with water. Cook.
Strain potatoes in colander. Place potatoes back in pan and put over heat for 30 seconds to get rid of all of the water.
Rice potatoes into a large bowl. Add cream cheese, sour cream, salt and pepper.
Stir potatoes until smooth, but be careful not to over mix. Place potatoes in greased baking dish, top with two pats of butter, cover and refrigerate until baking time.
FAQs
There is a lot of discussion out there about which potatoes make the best mashed potatoes. I love to mix it up and use both Yukon Gold and Russet potatoes for my mashed potatoes.
The Yukon Golds add a creamy buttery texture and the Russets are high in starch making them light and fluffy. Combining the two of them together gives you the best of both worlds. Who doesn't love getting everything they want in the same delicious bite?
You have a couple options here: You can reheat them in the oven, use a slow cooker or in a pinch, pop them in the microwave.
Room temperature ingredients will blend into the potatoes faster so you won't over mix your potatoes. Over mixing = gluey potatoes.
Expert Tips for the best mashed potatoes
Use these easy tips to make craveable mashed potatoes every single time.
- Cube the potatoes so they are the same size. Potatoes that are cut into small cubes work best for this recipe because they will cook evenly.
- Do not overcook your potatoes. Boil them for 9-10 minutes or until a fork goes into them easily. If you cook them too long you will end up with mushy potatoes.
- Drain them well! This is a BIG one. Drain, drain, drain and then pop them back in the pan and place on stove for 1 minute to get all of the excess water out of them. This critical step gives you fluffy potatoes!
- Invest in a potato ricer - This is the MOST important tip of all. One of my ALL time favorite kitchen gadgets is this potato ricer. The triangular shape makes ricing the cooked potatoes a snap and nothing gets stuck in the corners. (Amazon Affiliate Link)

- Oven: Preheat your oven to 350°F. If your potatoes have been in the refrigerator, let them sit out for 60 minutes before you pop them in the oven as it will cut down on your baking time. Leave them in the oven until they are warmed through, about 30 minutes (or more depending on if your oven is full of other dishes that need to be cooked).
- Slow Cooker or Crock Pot: I love to use my slow cooker to reheat these, especially with big holiday dinners. Simply heat them on high for one hour or low for 2-3. Stir occasionally so the bottom doesn't burn.
- Microwave: I'll use the microwave to reheat these in a pinch. Pop them in the microwave for 2-3 minutes and then stir. Repeat the process until heated through. Be careful when you touch the bowl, it will be hot!

Hi Sue, It serves 6! Although my family of 4 doesn't have a problem polishing them off when it isn't part of a huge meal. Hope that helps!
I tried these spuds ( using 2/3 part red potatoes & 1/3 part russets) and froze them in a buttered glass 9X13 pan... thawed them slowly in the frig, and then reheated them in the oven. ABSOLUTELY PERFECT!!! So good!!!
Nice to know I can make them as a freezer meal too!
Hi Kristin! Thank you for stopping back and leaving such a valuable tip! So happy that you liked the potatoes-they are the only mashed potato recipe my kids like! Thanks for being a GWL reader!
Hi! Just wondering if I cover them when reheating to keep moist?
Hi Betty, Yes I reheat with it covered with foil. Hope this helps. Thanks!
I made these the day of, because the wind knocked our power out the day before, and quantities were slightly off bc I needed to make 5 lb of potatoes but forgot to buy enough extra to double or almost double the recipe, but still... these were the best mashed potatoes I've ever made by far, and maybe the best ones I've ever had. SO GOOD! Great recipe!
Hi Steffie- I love these potatoes too, my family knows when I try something new and ask what I did to the potatoes.This recipe is pretty forgiving but gives you the creamiest potatoes. I'm so happy that you love them too!
