mashed potatoes recipe for 8 people is one of those things that sounds simple until you are actually standing in the kitchen, trying to time everything, and someone is asking, “Are these going to be creamy?” I have been there. This is the version I make when family is coming over and I want zero drama on the table. It is fluffy, buttery, and the texture stays smooth instead of turning gluey. If you are feeding a crowd, this is the kind of side dish that quietly saves the day.
How to Make Mashed Potatoes
I make these when I need a reliable bowl of comfort that goes with basically anything. The goal is simple: soft potatoes, warm dairy, and gentle mixing so you keep that cloud like texture.
What you will need
- 5 pounds Yukon Gold potatoes (or see potato options below)
- 1 1/2 tablespoons kosher salt, plus more to taste
- 1 1/2 cups whole milk (or half and half for richer potatoes)
- 10 tablespoons unsalted butter (that is 1 stick plus 2 tablespoons)
- 1/2 cup sour cream (optional but highly recommended)
- 2 to 3 cloves garlic, peeled (optional for a gentle garlic note)
- Black pepper, to taste
Step by step directions
1) Peel the potatoes, then cut them into even chunks, about 2 inches. Even pieces cook at the same speed, which means no half raw pieces hiding in there.
2) Put the potatoes in a big pot and cover with cold water by about an inch. Add the salt. If you want that mellow garlic flavor, toss the peeled garlic cloves into the pot too.
3) Bring to a boil, then lower to a steady simmer. Cook 15 to 20 minutes, until a fork slides in easily. If you have to push hard, they need more time.
4) While they cook, warm the milk and butter together in a small saucepan until the butter melts. Do not boil it. Warm dairy blends better and helps prevent the potatoes from cooling down too fast.
5) Drain the potatoes well, then put them back in the hot pot. Let them sit 1 minute so extra steam can escape. This little pause is what keeps your mash from getting watery.
6) Mash gently. A potato masher is perfect. If you use a hand mixer, keep it on low and stop the second it looks smooth. Overmixing is where that gummy texture comes from.
7) Pour in most of the warm milk and butter mixture, then add sour cream if using. Stir, taste, and add more warm liquid as needed. Finish with black pepper and an extra pinch of salt if it needs it.
If you are serving these with something bold and saucy, you are in for a good night. I love pairing them with tangy mains like Dr Pepper Barbecue Sloppy Joes because the creamy potatoes calm everything down in the best way.

What are the best potatoes for mashed potatoes?
I have tried a bunch of options over the years, especially when I am cooking for a bigger group and the grocery store is picked over. Here is the honest breakdown.
Yukon Gold is my favorite for this mashed potatoes recipe for 8 people. They are naturally buttery, they mash easily, and they taste rich even before you add a ton of dairy.
Russet potatoes are the classic fluffy choice. They make a lighter mash, but they can get a little dry if you do not add enough warm milk and butter. They also need a bit more attention to avoid lumps.
Red potatoes can work, but they are waxier. If you like a chunkier, rustic bowl, go for it. If you want the smooth, silky thing, pick Yukon or Russet.
One more tip that really matters: do not start potatoes in boiling water. Start in cold water so they cook evenly. If the outside overcooks before the center is tender, you can end up with weird texture.
“I made this exactly for Sunday dinner and everyone asked what I did differently. The texture was so smooth and the flavor was buttery without being heavy. This is my new go to for holidays.”
When I want something fun and different with potatoes, I also make these cheesy mashed potato puffs with leftovers. They are crispy on the outside and they disappear fast.
How to Store Mashed Potatoes
If you are making this mashed potatoes recipe for 8 people, there is a decent chance you will have leftovers. Or you might be smart and make them ahead so dinner feels easier. Either way, storing them right keeps them creamy.
Fridge: Let the potatoes cool a bit, then store in an airtight container for up to 4 days.
Freezer: You can freeze mashed potatoes, but they are best when they have enough fat in them. This recipe does, so it freezes well. Pack into a freezer safe container, press plastic wrap against the surface, then lid. Freeze up to 2 months.
Reheating tips that actually work:
- Stovetop: Warm on low with a splash of milk, stirring often.
- Microwave: Cover and heat in short bursts, stirring in between. Add a little butter if they look dry.
- Oven for a crowd: Put in a baking dish, add a few pats of butter, cover with foil, and warm at 350 F until hot.
If you are planning a big meal, I like making the potatoes first, then focusing on the main. For example, if I am cooking something like baked chicken parmesan, having the mash ready makes everything feel calmer and more organized.

Best Mashed Potatoes Recipe
This is the part where I tell you what makes this my best mashed potatoes recipe for 8 people, and it is not fancy. It is just a handful of habits that keep the results consistent every time.
My non negotiables:
Warm milk and butter: cold milk cools the potatoes fast and makes you stir more, which is not your friend.
Do not overmix: mash, then stir just until combined. Stop earlier than you think.
Salt the water: it is the easiest way to season the potatoes all the way through.
Steam off extra water: that one minute in the hot pot after draining is small but mighty.
Easy flavor upgrades if you want them:
Add roasted garlic, a pinch of onion powder, chopped chives, or a little cream cheese. If you are serving gravy, keep the seasoning simple and let the gravy do the loud talking.
When I put this mashed potatoes recipe for 8 people on the table, I expect silence for the first few bites, then someone asking if there is more in the kitchen. That is always the sign it worked.
Common Questions
Can I make mashed potatoes ahead of time?
Yes. Make them up to 2 days ahead, store covered, then reheat with a splash of milk and a couple pats of butter.
Why did my mashed potatoes turn gluey?
Usually it is from overmixing or using a blender or food processor. Stick to a masher, or mix very gently on low.
How do I keep mashed potatoes warm for serving?
Use a slow cooker on warm, or keep them covered in an oven safe dish at 200 F. Add a little butter on top to keep them from drying out.
Can I use milk alternatives?
You can. Unsweetened oat milk works pretty well. Add a bit more butter or olive oil to keep them rich.
How much should I make per person?
For a crowd, plan about 1/2 to 3/4 pound of raw potatoes per person. This recipe uses 5 pounds and comfortably feeds 8 with normal portions.
