I can’t share a mashed potatoes recipe without mentioning my husband Jack. He LOVES homemade mashed potatoes, specifically ones that are rich, creamy, and flavorful.
I’ve made plenty that he’s liked in the past (see these garlic mashed potatoes and these Instant Pot mashed potatoes). But last year, I finally made the potatoes he’d been waiting for: ones loaded up with butter, milk, and sour cream.
I’m not kidding when I say that these are the best mashed potatoes I’ve tried. They’re ultra-rich and blissfully creamy, and the sour cream gives them a delicious tangy kick. They’re easy to make (and make ahead!), and they’re guaranteed to be a crowd pleaser at Thanksgiving or any meal. If not from me, then take it from Jack—you’re going to love this mashed potatoes recipe.
How to Make Mashed Potatoes
You can find the complete recipe with measurements at the bottom of this post, but for now, I’ll give you an overview of how it goes:
Ingredients
This classic recipe starts with 7 simple ingredients:
- Potatoes, of course! 3 pounds yields enough for about 8 people. Double the recipe if you’re serving more!
- Garlic – For savory depth of flavor.
- Unsalted butter – For richness and buttery flavor.
- Milk – It smooths the starchy potatoes into an incredibly creamy mash. Use whole milk for the creamiest results.
- Sour cream – Technically, this ingredient is optional. If you skip it, the recipe will still come out great. But for the best mashed potatoes, I highly recommend folding it in! It makes the taters extra-creamy and gives them a tangy taste.
- And salt and pepper – To make all the flavors pop!

What are the best potatoes for mashed potatoes?
I think Yukon Golds and russets are the best potatoes for mashing.
- Yukon Gold potatoes are thin-skinned yellow potatoes. I love to mash them because they have a creamy texture, rich golden color, and buttery flavor.
- Russet potatoes are white potatoes that are high in natural starches. Thanks to all that starch, they yield fluffy mashed potatoes.
Feel free to make this recipe with either of these types of potatoes.
Another option I like is to use a mix of both kinds. The russets help with fluffiness and the Yukon Golds supply great flavor. It’s a combination that can’t be beat!
Preparation
My method for how to make mashed potatoes couldn’t be simpler! Here’s how it goes:
First, peel and cut the potatoes. Chop them into large chunks—halve smaller Yukon Golds and cut larger russets into quarters or sixths. Do your best to cut the pieces to a consistent size so that they cook evenly.
Next, cook. Place the potatoes and garlic in a large pot and cover with cold water by 1 inch. Add a tablespoon of salt, and bring the water to a boil over high heat. Reduce the heat to medium and gently boil until the potatoes are fork-tender.
How Long to Boil Potatoes for Mashed Potatoes
When I make this recipe, I generally boil the potatoes for 15 to 20 minutes.
But the timing can vary! The potatoes are ready when you can easily pierce them with a fork. Avoid undercooking them. If they’re still firm in the center, you’ll end up with lumpy mashed potatoes!
When the potatoes are tender, drain them into a colander. Lightly shake to remove excess water, and return the potatoes to the pot.
Finally, mash! Use a potato masher to partially mash the potatoes. Then, pour in the milk and add the butter, salt, and pepper. Continue mashing until the potatoes reach your desired consistency (we like them totally smooth!). If desired, use a wooden spoon or spatula to stir in the sour cream.
Season to taste, adding more butter, sour cream, and salt and pepper as needed. Enjoy!
Recipe Tip
Don’t forget the fixings! We love these potatoes with butter, chives, and salt and pepper on top. You can’t go wrong with mushroom gravy either.
How to Store Mashed Potatoes
Leftover mashed potatoes keep well in an airtight container in the refrigerator for up to 3 days.
You have a few options for reheating them:
- In the microwave – Microwave until heated through, stirring every 2 minutes.
- In the oven – Transfer the potatoes to a casserole dish or oven-safe pan. Dot the top with butter and cover. Warm in a 350°F oven until heated through, 25 minutes or more depending on the size and shape of your baking dish.
I’ve also had success reheating these mashed potatoes using the Keep Warm setting of my Instant Pot. A slow cooker would work well too!
If the potatoes seem dry after reheating, stir in some melted butter or a splash of milk to loosen them up.

Loved this recipe! Got several compliments from family and friends and a few who asked for the recipe!
Have cooked it twice now.
Used only 1/2 cup of Oat Milk and used 1/2 cup of sour cream.
Garlic was a great addition.
Forgot to include garlic the second time I made it and it still tasted great.
my boyfriend and his family LOVE this recipe i’ve made it like a bajillion times and he loves helping me mash- it’s to the point where i have the recipe memorized and i can feel in my heart what amounts i need to add when making smaller batches !!!! 15/10
Recipe for 3lb potatoes is way off – 1 cup of milk in 3 pounds of potatoes makes porridge. Good thing I have 2 more lbs of potatoes
I don’t find this to be a case at all. Keep mashing and allow the milk to absorb. You can also put the potatoes through a ricer that will make them smooth.
I veganized this recipe, subbing in full-fat oat milk, vegan butter, and plain unsweetened cashew yogurt.
They were creamy and delicious!
I’m so glad you loved it, KP!
These mashed potatoes are light and fluffy and so easy to prepare. Pure deliciousness!
I’m glad you loved them!
These mashed potatoes were AMAZING! I subbed heavy cream for the milk since I needed to use it up. I don’t know if that’s what made the difference or that I accidentally tripled the garlic, but really, these were to die for.
I like the recipe cause it was easy and I’m young. The result was phenomenal.
I’m trying this recipe out tomorrow. Just to be sure… you boil the cloves in with the potatoes?
Too much liqiud. I only needed 1/2 cup, not the full cup. Also too salty, and i only added 1 tsp of salt. Came out pretty good otherwise
Absolutely delish – keeper of a recipe! I added the sour cream and went a little lighter with the salt. Also, if you use room temp butter and sour cream, and warm up the milk before adding, it helps to keep the potatoes from cooling down too much.
I’m glad you loved them!
Can I use an immersion blender instead of a masher?
Hi Alyson, no, the potatoes will get gummy, a masher is best.
About how many medium sized potatoes are in 3 lbs. I don’t have any way of weighing them. I’m using 1/2 yukon and 1/2 russets.
Hi Kiki, it should be 3-4 russets and 4-6 yukon golds, it depends on the size. But the recipe should be forgiving if there’s some variation, start with a little less milk (you can always add more), and season to taste.
Quick question. I know that the recipe suggests whole milk, but if you were going to make this with non-dairy milk, is there a type that would work best? Thanks in advance!
Hi Jennifer, you can totally use non-dairy milk! I might not do oat milk just because it has a fairly oat-y flavor. We’ve used almond milk and it works well! I would start with less and add more as needed because it’s much thinner than whole milk.
I made it vegan with plant based butter and plain unsweetened oatmilk. Terrific!!
this recipe made me the best dinner ive had in months!!!
Can you nake the potatoes ahead of time?
yep!
would it work to make same day and leave in crock pot on warm until dinner time?
That should work fine!
How do you keep it hot? After following your directions, the end result was lukewarm mashed potatoes.
Hi Ronda, if adding the milk cools them down too much, turn the stove on and heat them until warmed.
I always make sure my butter and sour cream is room temp. And I warm up my milk in the microwave for about 30-45 seconds. That keeps the potatoes hot!
So good! Perfect and easy! Thank you!
Very good. Loved the recipe
I made this recipe for my son who loves mashed potatoes and we both loved it! I didn’t need to change a thing. Thanks for the recipe!
I’m so glad it was a hit, Heather!
I used to have my favorite mashed potatoes recipe for almost 10 years, but now I had some sour cream about to expire so I tried this recipe. I’m never going back to my old recipe, this one is so good! My new go to mashed potatoes recipe. Thank you for sharing!!
I’m so glad you loved it, Valentina!
