The tang of buttermilk with crumbles of blue cheese amp up the flavor in these 5 ingredient blue cheese mashed potatoes.
Buttermilk Blue Cheese Mashed Potatoes
The best part of dinner, especially when it’s a holiday dinner, is the side dishes. And when the side dishes are rocked with flavor, the main dish can just scooch on over to the sidelines.
When you’re operating in the multiple side dish zone (which seems to be the theme of this list of 50 favorite Thanksgiving side dishes) it’s a good idea to keep those side dish recipes simple. Complicated, overwrought 182 ingredient recipes just aren’t what the frazzled home-cooking-hostess needs when cooking the years favorite feast.
We all love the classic and creamy buttery mashed potatoes recipe, but when you’re craving a little something extra to serve alongside the best classic roasted turkey or this out of the box buffalo roasted turkey, adding just two ingredients takes basic mashers to SMASHERS!
What’s In Blue Cheese Mashed Potatoes
These decadent 5-ingredient mashed potatoes start off with Yukon gold potatoes for their creamy, buttery texture. Save the waxy white or red potatoes when your tater for my favorite potato salad or these easy buttery parsley red potatoes.
Here’s what’s in these blue cheese mashed potato recipe:
- Yukon gold potatoes for the creamiest blend, cut into quarters for quicker cooking
- Buttermilk, to give the potatoes a bright tang (you could use cream, half and half, or milk instead)
- Real butter. Always real butter.
- Freshly crumbled blue cheese. Please, please, please, avoid the pre-packaged crumbles and buy the whole blocks of blue cheese and crumble yourself instead. There’s a difference you most certainly will taste.
- Chives or really thin sliced green onion
How to Get Smooth and Creamy Mashed Potatoes
Salt the water so the potatoes soak in flavor as they cook. My husband always reminds me to add the salt after the water has come to a boil so the salt doesn’t pit the bottoms of the pans. Cook the potatoes whole, or quarter the potatoes before cooking so they cook faster, usually in about 10-15 minutes or until fork-tender.
Put the taters back in the pot. A trick I’ve found to get an extra creamy potato is once the skins are quickly removed, I add the potatoes back to the same warm pot I cooked them in, then lightly smash them with the hand mixer tines, and add my butter to the still-hot potatoes. Cover the potatoes with a lid and let them sit for a couple of minutes, allowing the potatoes to dry out a little, keep warm, and absorb the melting butter for a barrier.
Add the butter before the buttermilk. Adding the butterfat to the potatoes before adding the buttermilk, coats the potato starches and acts as a barrier to ensure your mashed potatoes won’t turn out gummy, sticky, or over mixed.
Whip ‘em with a mixer. The real secret to great mashers is how you mash them. I’ve used a ricer, but it’s a bit of a pain and my muscles never seem strong enough. I’ve used a masher, and get a tasty mashed potato but always have a few potato chunks. That’s why I’ve returned to my potato roots and use an electric hand mixer just like my mom and grandma used to do. I still use my mom’s trick of setting the pot of potatoes in the sink to whip them, so the hand mixer doesn’t send potato particles across the kitchen.
Stir in the blue cheese chunks and chives. Fold in the flavor makers, but again, be careful not to over mix, and season with kosher salt and pepper to taste.

Blue Cheese Mashed Potatoes
- 2 ½ pounds yukon gold potatoes
- 1 teaspoon kosher salt , plus more for seasoning
- ⅓ cup buttermilk
- 4 tablespoons butter
- 4 ounces blue cheese , crumbled, plus more for garnish
- ¼ cup chives , plus more for garnish
- freshly ground black pepper
- Scrub the potatoes clean and add to a deep pot. Completely cover the potatoes with water, about ½ inch above the potatoes. Bring the potatoes to a boil and add ½ teaspoon of kosher salt. Boil the potatoes for 20 to 30 minutes or until they are very easily pierced with a fork and the skin pulls away from the potato where cut.
- Drain the potatoes, and while still hot, use a paper towel to wipe the skin away from the potatoes, then add back to the warm pot. Gently smash the hot potatoes with the tines of a hand mixer and add the butter to the potatoes. Cover with a lid for the butter to melt, about 3-4 minutes.
- Add the buttermilk to the pot and set it in the kitchen sink so the potatoes don't fly around the kitchen while whipping. Cream the potatoes with the hand mixer until smooth, rotating the pot counter-clockwise as you mix. Don't over mix the potatoes. Add the remaining ½ teaspoon of kosher salt and black pepper to taste. Stir in the crumbled blue cheese and chives. Garnish with additional blue cheese and chives.

You should never cut your potatoes in quarters to cook them. one should start with cold water, whole potatoes and bring to a gentle boil. This is to avoid knocking the starch out of the potato and making them turn to glue which you do by over whipping as well. For the best, after boiling place in a perforated pan at 350 degree oven to dry them out for 20 minutes to achieve the lightest fluffiest mashed potato.

Praveen @ Awesome Cuisine
Love mashed potatoes. And love this blue cheese version.
Bring on the sides! You’re right, I care more about the sides than the actual main. These look absolutely flavorful and fluffy.
yes, yes, yes!! It’s always about the sides, especially the mashed potatoes, oh, and the stuffing, and then there’s the rolls and BUTTER! I love love your twist on the traditional mash adding in blue cheese – bold and yummy!

Phi @ The Sweetphi Blog
You’re so right…mashed potatoes are the best part of any meal lol. I just last night was out to dinner with my hubby and he got garlic mashed potatoes and I got mac n cheese…we ended up trading because I’m a little borderline obsessed with potatoes. These mashed potatoes look amazing!
Oh my goodness – last year I made some mashed potatoes with blue cheese and they were life changing. Sounds crazy to say it about potatoes, but wow. Now I need these with the buttermilk. YUM!
I love, love, love blue cheese and mashed potatoes together. These look and sound incredible!
Ooops, just saw the “8 servings” reference at the top of the recipe. Please disregard my earlier question!
This looks terrific — how many servings does this recipe make?
Michelle @ A Dish of Daily Life
