The BEST buttermilk mashed potatoes recipe: Roasted Garlic Buttermilk Mashed Potatoes
When it comes to Thanksgiving dinner, some people are all about the turkey. Others are all about the stuffing. Or the green bean casserole. Or dowsing everything in gravy.
But for me? When it comes to Thanksgiving dinner, I am ALL about the mashed potatoes.
&…Um HELLO…can you blame me?
In our house, Chris is our designated potato masher. He’s been in charge of making the mashed potatoes ever since the Infamous nearly-flooded kitchen incident of friendsgiving 2014.
Quick refresher: we hosted a holiday dinner together for the first time in 2014 & it was NOT one of our best days. **Someone** (cough, Chris, cough) was feeling a little under the weather from having a little too much fun the night before & **someone else** (cough, me, cough) was feeling a little overwhelmed from taking on too much for the meal. I was rushing to get the potatoes boiling & after peeling all the potatoes in the sink, it seemed like running the garbage disposal would be a quick way to clean them all up. BOY was I wrong. I almost flooded our kitchen!!!
Ever since then, Chris has been on mashed potato duty at Thanksgiving dinner. & That’s honestly totally okay with me because dude makes a MEAN buttermilk mashed potato. They’re kinda famous amongst our family & friends because everyone flips out over how perfect they are: fluffy, creamy, buttery, & pretty for dousing in tons of turkey gravy.
This roasted garlic buttermilk mashed potatoes recipe is pretty much Chris’ kinda-famous buttermilk mashed potatoes, with a couple of my own little touches to take them completely over the top:
- Yukon gold potatoes, which have the most insane tender & buttery texture, perfect for mashed potatoes.
- A full head of roasted garlic, which gets swirled into the potatoes just before serving & adds deep, caramelly garlic flavor to every single bite.
The result? Roasted garlic buttermilk mashed potatoes perfection.
What goes in roasted garlic buttermilk mashed potatoes:
Aside from the fact that they’re so freaking delicious, one of the things I love most about these roasted garlic buttermilk mashed potatoes is that they’re really easy to whip up & they’re made entirely with pantry staples:
- Yukon gold potatoes
- Olive oil, , ground black pepper
Yes! That’s really all it takes to make the perfect mashed potatoes. This roasted garlic buttermilk mashed potatoes recipe is really the type of recipe that transforms some of the most humble ingredients into something that’s magically greater than the sum of its parts.
Keep on reading to learn just how freakin’ easy it is to make these roasted garlic mashed potatoes, as well as about some of my tips for the perfect roasted garlic buttermilk mashed potatoes!
How to make roasted garlic buttermilk mashed potatoes:
Other than the fact that they’re made with really simple ingredients, this roasted garlic buttermilk mashed potatoes is my favorite because it’s sooooo freakin’ easy! While it’s perfect for Thanksgiving, or for a special holiday dinner, you really can make them any day of the week & any time of the year because they’re so easy to throw together.
Here’s how it goes:
- Roast the garlic.
- Boil the potatoes.
- Mash, mash, mash.
- Serve (…& devour!)
First, the garlic.
Roasting garlic is one of those things that might seem a little intimidating, but it really doesn’t need to be. At all. You lob the top off of a whole head of garlic & place it in some aluminum foil, then drizzle it with some olive oil and give it a good sprinkle of salt & ground black pepper before wrapping it up and popping it in the oven for an hour.
While you definitely don’t need roasted garlic to make epic buttermilk mashed potatoes, it definitely takes them to the next level! The garlic slowly roasts & caramelizes in the oven (which, by the way, will make your whole house smell a-freaking-mazing!) until it’s totally soft & totally full of perfectly roasty, garlicky flavor.
Meanwhile, as the garlic roasts, you start on the potatoes!
I always use yukon gold potatoes because they have the most insane buttery & creamy texture (I’ll talk you through more of that in just a sec!), but they also have really tender skins, which means you don’t even have to peel them!
This brings us to one of the more controversial points of mashed potato discussion: to peel or not to peel?!
In our house, we like our mash to be pretty creamy but also kind of rustic. for this reason, & because Yukon gold potatoes have such a tender skin, I just forego peeling the potatoes altogether. If you do want to peel your potatoes, have at it! I’d recommend grabbing some of these y-peelers – they make peeling go by so, so, so much faster!
The potatoes get boiled in some salty water, which helps impart extra flavor in those potatoes as they cook. Once they’re fork-tender, which takes about 20-25 minutes if you dice your potatoes into 1-inch cubes, it’s time to mash! I like to add butter & buttermilk gradually as the potatoes mash, working them to just the perfect texture.
Again, since we like a more rustic mashed potato, we just use a potato masher. If you’re really particular about super creamy mashed potatoes, run your boiled potatoes through a potato ricer once or twice to get that ultra-creamy texture.
Lastly, you stir in the roasted garlic, which should be so soft that it squeezes right out of the bulb, to fold in caramelly garlic flavor into every bite of roasted buttermilk mashed potatoes.
& Lastly? Pop them in your favorite serving bowl & cover them with some melted butter, freshly snipped chives, & TONS of freshly cracked black pepper.
Hello potato heaven.
Tips for perfect roasted garlic buttermilk mashed potatoes:
1. The best potatoes for making mashed potatoes
= Yukon gold potatoes!!! They have an insanely tender & buttery texture that lends them to mashing so insanely well. They’re a little more expensive than your standard russet (but honestly not that much more expensive…), but the payoff is totally there because they create the perfectly fluffy texture for these roasted garlic buttermilk mashed potatoes & add tons of buttery flavor.
2. Don’t skimp on the butter!
Please, please, please don’t skimp on the butter!!!
I think one of the things that makes people most uncomfortable about mashed potatoes is the mashed potato philosophy that “when in doubt, add more butter”. But there’s a lot of truth to it! Potatoes need butter. They’re BFFs! Butter adds so much flavor & helps make the potatoes super creamy.
So while this roasted garlic mashed potatoes recipe calls for a full stick of butter, remember that you’re making enough potatoes for eight servings. A lot of potatoes = a lot of butter, but it really only boils down to 1 tablespoon of butter per serving.
I strongly suggest using the best quality unsalted butter you can find. Always opt for unsalted so you have total control over the amount of salt you’re adding to your potatoes!
3. Substitutes for buttermilk in roasted garlic buttermilk mashed potatoes
While it’s kind of the star of the show, I totally get it: you don’t always have buttermilk on hand. Luckily buttermilk is pretty easy to doctor up at home.
Simply add 1 tablespoon of vinegar or fresh lemon juice to 1 cup of milk, let it sit & curdle for a minute, then give it a stir. Voila! Homemade buttermilk that will still add great tangy flavor to these roasted garlic buttermilk mashed potatoes without an extra trip to the store. Easy!

An easy & super creamy roasted garlic buttermilk mashed potatoes recipe! Yukon gold potatoes get mashed until perfectly creamy with butter & buttermilk, then finished with deeply caramelized roasted garlic. The perfect side dish for Thanksgiving, Friendsgiving, or any holiday dinner!
- 1 head garlic
- 2–3 teaspoons olive oil
- 4 pounds Yukon Gold potatoes, cut into 1-inch dice (see Recipe Notes)
- ½ cup unsalted butter, cut into tablespoons
- 2 cups buttermilk (see Recipe Notes)
- 1 tablespoon + ½ teaspoon Kosher salt, divided
- ½ teaspoon freshly ground black pepper
- for serving: freshly snipped chives, tons of freshly cracked black pepper
- Roast the garlic: Preheat the oven to 375 degrees F. Chop just the top off of the head of garlic, to just reveal its cloves. Lightly rub the garlic to loosen and remove any excess paper. Wrap the garlic in foil, drizzling it with the olive oil before you seal the foil, then place in the oven and roast for 45 minutes, or until golden brown. Remove from the oven and set aside.
- Cook the potatoes: Meanwhile, as the garlic roasts, cook the potatoes. Place the diced potatoes in a large, heavy-bottomed Dutch oven and cover with 8 cups cold water, or enough to completely submerge the potatoes. Season with 1 tablespoon Kosher salt. Place the pot over medium-high heat and bring to a boil. Reduce to a simmer for 20 minutes, or until the potatoes are fork tender. Carefully strain the potatoes, then return to the pot.
- Mash the potatoes: Use a potato masher to mash the potatoes to your desired consistency. As you’re mashing the potatoes, slowly add in the butter, one tablespoon at a time, and the buttermilk. Alternate as you go – a little butter, then a little buttermilk. Once the potatoes have reached your desired consistency, add in the roasted garlic – the cloves should squeeze out of the garlic bulb very easily. Stir to combine. Taste and season with additional salt and ground black pepper, to taste. I add ½ teaspoon each, taste, go from there.
- Serve the roasted garlic buttermilk mashed potatoes immediately, with lots of freshly cracked black pepper & freshly snipped chives, as desired. Enjoy!
- Yukon Gold potatoes are the BEST potatoes to use in mashed potatoes. They have an insanely tender & buttery texture that lends to mashing so well. They’re a little more expensive than your standard russet (but honestly not that much more expensive…), but the payoff is totally there because they create the perfectly fluffy texture for these roasted garlic buttermilk mashed potatoes & add tons of buttery flavor.
- Substitutes for buttermilk in roasted garlic buttermilk mashed potatoes: If you don’t have buttermilk at home, you can easily make a buttermilk substitute by simply adding 1 tablespoon of vinegar or fresh lemon juice to 1 cup of milk. Let it sit & curdle for a minute, then give it a stir. Voila! Homemade buttermilk!
- Mashing potatoes: Because Yukon Gold potatoes have a very tender skin & because we like a more rustic mash in our house, we just leave the peels on. They don’t affect the creamy texture of these potatoes too much. If you’re obsessed with really creamy & smooth mashed potatoes, you can accomplish that with this recipe by peeling the potatoes & by using a potato ricer.
