Meet your low-stress, extra-creamy mashers. These cook right in the crockpot—no boiling—and stay warm until dinner. Three cheeses and a swirl of browned sage butter make them holiday-worthy with weeknight ease.

Say hello to your new favorite way to make everyone’s favorite Thanksgiving side dish. Yes, the crockpot!! You guys, in all honesty, if there was ever a crockpot recipe to know how to make, it has got to be these mashed potatoes. If you think about it, it’s kind of brilliant. Let me put it this way, not only does it free up space on the stove, but it there’s NO BOILING the potatoes and so much less clean up, AND the crockpot will keep your mashers warm until ready to eat, meaning no reheating necessary. YESSS.
It’s like our Thanksgiving prayers of have been answered. Slightly dramatic, but kind of true, seeing that everyone has mashed potatoes on their Thanksgiving table…I mean, they are everyone’s favorite turkey day side, right?!
Every year on Turkey Day, Mom and I bake pies in the morning and then my family will typically go to cut down our Christmas tree, while I cook away in the kitchen. Some years I’ll hike up the hill with them, but in recent years I have had so many dishes that I MUST make (I mean there are so many great dishes I want to get on the table!) that I end up staying back in the kitchen. This is totally fine by me because I blast Christmas music and have a “no pressure” cooking day. I know for a lot of you Thanksgiving day is stressful, but for me, it’s one of my favorite days to cook because for once I am not cooking to test a recipe and then photograph it, so the pressure is off. I cook recipes I know my family is going to love and it’s great!

The one problem I run into every single year is stove top and oven space. I’m sure all of you who do a lot of cooking know exactly what I am talking about.
Well this crockpot three cheese mashed potatoes recipe solves A LOT of problems, and is now the only way I will make mashers. <–truth.
Not only does this method save space on the stove, but it also creates way less mess. You can start the potatoes in the morning and then literally not think about them again until just before dinner. And even then, all you have to do is mash them, add cheese, butter and DONE.
It’s really just a magical thing, which I’m clearly pretty excited about it, plus, did I mention the cheeses!?!
I know, I know, as if mashed potatoes weren’t already amazing, I had to go and add not one, but THREE cheeses. Clearly my Thanksgiving motto is go big or go home. ?



So, what cheeses did I choose?
Umm, cheddar, Parmesan, and Gruyere. I mean, obviously. Some of my favorite cheeses right there, they’re what take these mashed potatoes from ordinary to all kinds of incredible.
OK, and the browned butter helps too.
I was talking with my brother Malachi the other day and I asked him the question, cheese or no cheese in your mashed potatoes? His response was one that made me just so proud. He said, “I mean, is that even a legit question, always cheese”. So then I asked cheddar, Parmesan or Gruyere? Again, his response was so on point, “all three, cheese is great, the more cheese the better”.
Smart kid right? He is 100% a Gerard and I could not agree with his statements more, so all three cheeses it is!


When making mashed potatoes, I like to use whole milk. Actually, I use whole goat milk. I of course prefer goat milk seeing as we have gallons and gallons on hand at all times, now that we are milking all three mama goats, plus I really do love it!
In all seriousness though, these mashed potatoes are life changing in both the way that they are cooked, and in the way that they taste. I am SO excited to make them again for Thanksgiving and am crossing my fingers that these are going to be on all of your Thanksgiving menus too! Or maybe even sooner for an easy weeknight dinner side dish…hint, hint…great recipe to serve them with coming Wednesday! Until then, here are my current favorite blog recipes to serve these mashed potatoes with, pot roast, short ribs and Coq au Vin.
Can I leave the potato skins on?
Yes—skins add texture and nutrients. Yukon Gold skins are thinner and blend in more smoothly than russet.
How do I keep these creamy on Warm without drying out?
Stir every so often and fold in small splashes of warm milk or a pat of butter as needed to keep the texture lush.
Can I double this for a crowd?
If your slow cooker can handle the volume without exceeding about two-thirds full, yes. Plan for a bit more time until potatoes are uniformly fork-tender.
What if I don’t have Gruyère?
Use fontina or more cheddar for melt; flavor will be a touch less nutty. Parmesan adds saltiness, so taste before adding extra salt.

Ahh, I for sure would be ok with that kind of Monday night dinner! Gimme please!
You just took mashed potatoes to a whole new level! These look incredible!
(: Thanks Laura!! Mashed potatoes are the best!!
These definitely sound so good and comfort food-y! In my family, we always always have potato filling for holidays instead of mashed potatoes or stuffing since it’s basically the two combined + more butter. It’s a Pennsylvania Dutch dish and I promise if you try it, you will never be fully satisfied by mashed potatoes although you once again lose some oven space 🙂
WOW!! Thats sounds seriously amazing!! I wouldn’t be surprised!! I bet I’d love them!!
Mmmm that just sounds perfect- I’m definitely adding to my Thanksgiving menu!!

Would it be wrong to save this all for myself? 🙂
Definitely making these for the holiday crowd.
Haha no definitely not!! I would totally do the same! I hope you and your guests love these when you make them, thanks Tina!
Okay, it’s settled.ni definitely have to start cooking my potatoes in a crockpot. I love the idea that there’s little mess and no boil. Plus, no reheat. And potatoes + cheese + sage? Yes!
HAha so happy you are loving this recipe! Thank you Andrea!
Yum! Great idea!
Thank you Sara!
What a great idea! One less pot on the stove–and how can you go wrong with cheesy mashed potatoes. I will definitely give this recipe a test drive before Thanksgiving. I’m wondering, though, how they would taste with turkey gravy. I am not a gravy fan but my family members are. Thoughts?
Hey Natalie!! These are great with gravy! Picky brother approved and all! 🙂
Let me know if you have questions. Thanks!
Crock pot for your potatoes! Shut up! This is something I’ve totally never tried!!! I can’t wait!

Perfect! I hope you all love it!! Thank you Jess!
With all that cheese, do you think you could sub water for the milk and achieve a similar effect?
Hey Marci, I would not recommend using all water. Maybe half water and half milk, but I would use some milk or I think the potatoes with be dry and bland. Let me know if you have questions. Thanks!
These are like the best looking mashed potatoes ever! I recently bought a slow cooker and it’s slowly becoming my favourite appliance in the kitchen. Mashed potatoes are now on top of my list to try!
Awesome! I hope you love these Richa! Thank you!
That looks so delicious! Thanksgiving is not a tradition here in the Netherlands, but I am in charge of Christmas dinner and I’ve been thinking about mashed potatoes… A LOT! It’s one of my favourite sides, so comforting and delicious. And adding cheese is, of course, genius. Saving this one!
