Grandma’s Way
The secret to mashed potatoes lies in the right floury potato (the russet), a potato ricer and, of course, indulgent fats such as cream and butter. Slow Cooker meals are the best. Here is Mashed Potatoes and all the options. Bonus: foolproof gravy #slowcooker #potatoes #gravy

Slow Cooker Mashed Potatoes Grandmas Way
Ingredients
- 5 Lbs Russet Potatoes Chopped
- 3-4 Cloves Garlic Optional
- 1 Tsp Kosher salt
- Fresh ground black pepper
- 3 to 3.5 Cups Milk
- .5 Cup Unsalted butter
Instructions
Peel and chop potatoes:
- Lightly grease the slow cooker insert with butter or cooking spray. Peel the potatoes and chop into small pieces about 1 inch to a side. The smaller the potatoes, the faster they will cook, obviously. Transfer the potatoes to the slow cooker.
Add the seasonings:
- Smash the garlic cloves, if using, and drop on top of the potatoes. Stir in the salt and a generous quantity of black pepper.
- Pour in 1 1/2 cups milk: Pour in 1 1/2 cups milk and stir the potatoes once.
Cook until tender:
- Cover the slow cooker and cook 4 to 5 hours on HIGH or until the potatoes are very tender and soft. Turn the heat to WARM.
Melt the butter:
- When the potatoes are done, melt the butter in a saucepan over low heat.
Warm the dairy:
- Stir 2 cups milk, or a mixture of milk and cream, into the melted butter and warm gently over low heat.
Mash the potatoes:
- If you used garlic but don't want the potatoes super garlicky, remove the garlic cloves and discard. Use a spoon to scoop out and discard any browned bits on the sides of the pot. Use a potato masher or ricer to mash the potatoes right in the pot.
Slowly stir in the dairy:
- When the potatoes are as smooth as you like, slowly stir in the warmed dairy and butter. The potatoes will look soupy at first but the potatoes will quickly soak up the liquid. Add an additional 1/2 cup of milk or cream if you want them to be even creamier.
Taste and season:
- Taste and season with additional salt or pepper if desired.
Keep warm:
- To keep the potatoes warm, leave in the covered slow cooker on the WARM setting for up to 4 hours.

I hope they will! You will love the ease of the prep. Have a great week!
Your gravy recipe is just like Grandma’s. Why mess with perfection. Very nice of your to share it with the measurements.
Thanks! It is a favorite in our home, too. Have a great week!
I need to add this to my list for next year. Thanks. Thanks for joining the To Grandma’s House We Go link party! Your post has been pinned!
i hope to get to try these mashed. Enjoy!
I love the idea of utilizing the slow cooker for the mashed potatoes. Among other things it frees up oven space for Thanksgiving.
That and not having to worry about burning or keeping them warm. it is definitely a win win!
These will be great Mashed Potatoes for any season! Thanks so much for sharing with us at our Thanksgiving Edition of Full Plate Thursday! Hope you have a great week and come back soon!

I love mashed potatoes so this version is a must for me! Have a great week!
I never even thought of using the crockpot for potatoes but I will definitely try the mash recipe
The one with the onions s my top pick. Reminds me of shepherds pie. Enjoy!
Both of these mashed potato recipes sound amazing! I’ve just got a slow cooker so I will have to try one of these for my Christmas mashed potatoes!

I can’t give these mashed a higher vote. It is so wonderful not to have to babysut them when all the last minute details of the meal need to be attended to. Enjoy!
Oooh slow cooker mash! That is something I have never tried, this is going on my to try list! x
It is such a pleasure to make those last minute mashed in the slow cooker. Have a great week!
Looks yummy! Thanks for sharing at Friday Frenzy Link Party! PINNED!
Thanks for the pin Kelly. #FridayFrenzy Have a great week!
Both these variations on Slow Cooker Mashed potatoes sound terrific, Marilyn! I love the idea of stirring the caramelized bits into the potatoes for flavour! The gravy looks wonderful too. There really is nothing like homemade from scratch gravy. Thank you so much for sharing and for being a part of the Hearth and Soul Link Party. I hope you and yours have had a wonderful Thanksgiving weekend!
Thank you so much April! I love the part of adding onions to the mashed too. Makes them a cut above the rest. #HearthandSoul Have a great week!
Wish I’da seen this before Thanksgiving Dinner! I’m definitely pinning it for next year: anything that frees up my stove top is a win in my book!
Thanks Michelle! I am glad you like the idea. i visited your blog and connected on FB. Love your theme! have a great week.
I had no idea this was even a possibility, good to know. Thanks.
I am glad you liked it. I found if you want to cook anything you can find a crock pot recipe for it! Have a great week!
I always struggle with gravy. It’s either all lumpy or too watery. Now I know why it’s lumpy, looks like I use too little fat. Thanks for that Marylin and for the recipe on your to make mash in a slow cooker. That’s a game changer. Hope you had a wonderful Thanksgiving dear lady.
I am glad this recipe is useful for you. Some of the simplest dishes have the hardest tricks to discover! My holiday was lovely. I hope you have enjoyed your week!
Never thought of doing mashed potatoes in the slow cooker – but this looks delicious. Thanks for sharing on BloggersPitStop#101
Thanks Claire. I hope you get the opportunity to try the crock pot on your mashed potatoes! Have a wonderful week.
You had me at slow cooker then threw in mashed potatoes – will you blog marry me? lol 😉
Seriously, these look delicious, can’t wait to try them. Thank you. Dropped by from #BloggersPitStop today but always happy to be here. 🙂
Hope this weekend treats you kindly. 🙂
I will blog marry you id you do the grocery shopping and dishes! LOL. I am glad you like the recipe. What a time saver asnd I never have to baysit them as I am finishing up the last minute tasks. Happy Holidays!
Very yummy! I have to have mashed potatoes and gravy every once in a great while. I’ve never tried making them in a crock pot. Thanks for sharing your recipes with SYC. Wishing you a Happy Thanksgiving.
hugs,
Jann
These are so good and never burn!!i love my crock pot. Happy Thanksgiving.
Shared on our hospitality group page – some were stressing over gravy! You’re invited: WelcomeHeart,WelcomeHome FB group – all things hospitality for heaven’s sake. (:
Thank you for the share and ivite Sue! I went to the group and it says I have applied so I guess I need to wait to be approved. Thank you I am so excited! Have a great week!
We’re hosting our first Thanksgiving – doing everything. Gravy has me so nervous so I’ll try your recipe! Visiting from Whisk It Wednesday.
The trick is to keep stirring while it thickens. I use a whisk. Don’t use a mixer whisk attachment as it adds too much air. Add flour slowly so it doesn’t clump. Add a bit at a time because it thickens a minute or so each time you add the flour. Don’t be afraid! Have a jar or two on hand just in case of prepared gravy. You can also substitute corn starch for the flour. Some folks swear it is less likely to clump. You will do fine! Stir, stir, stir! Good Luck!
Thank you for sharing! I love using a slow cooker and I have never given mashed potatoes a thought! I look forward to trying this recipe for the holiday!
It was a life saver last year when I needed to save space and not have to worry about making those potatoes at the last minute. Enjoy! Have a great week.
I would not have thought of doing potatoes in a slow cooker. I guess that’s one way to free up some of the hob when making dinner
Thank Jacqui! It is a space saver. Have a great week.
I’ve never tried mashed potatoes in my slow cooker but these look great! Great to be able to make a side dish in the crockpot for the holidays, so convenient to use less oven space. I run the Slow Cooked Challenge linky if you wish to join in, it would be lovely to see you there.
Thank you Lucy for looking at my mashed potatoes recipe. I would love to join your party. Thanks for the invitation. I will add it to my pinterest board and blog directory. Have a good week!
I’d never have thought mashed potatoes would be something you could make in your crock pot. Anything that can free up your hob is always a good plan!
I love this method snce it can stay warm without burning, creates less dirty dishes, and eliminates the steam in the kitchen. I hope you get to use it! Have a wonderful week.
I am going to try your “ultimate mashed potatoes” for Thanksgiving, Marilyn. It sounds so good and keeping them warm in the slow cooker will be helpful while I heat up everything else.
Have a very Happy Thanksgiving!
I just know they will be a big hit Pat. And you can’t beat NOT having to babysit them to stay warm so they don’t burn! Happy Thanksgiving!
Gravy is the bane of my existence, and every year I threaten to buy a can for Thanksgiving dinner. This year, I’ll use your recipe (and be thankful!).
Thank you Michele! You flatter me. Enjoy the gravy and Huge Thanksgiving blessings to you and your family.
Good Morning Marilyn, Oh my word, this is a triumph. I use my slow cooker quite a lot, but I would never have imagined that I could make mash potato using my slow cooker. I look forward to making my next batch of mashed potato using my slow cooker.
Thank you so much.
Have a lovely day and a wonderful Thanksgiving.
Best Wishes
Daphne
I hope you love the convenience as much as I do! Happy Thanksgiving!
I would have never thought of making mash in the slow cooker before. #mealplanningmonday
This method is excellent when you don’t need to watch an extra pan or need the burner. It eliminates the steam in the kitchen too! Happy Thanksgiving!
I have never cooked mashed potatoes in a slow cooker. It sounds like something I need to try out for the first time. I love mashed potatoes so much! I’m going to pin this recipe and try it out in the near future. Thanks for sharing!
Thanks for the pin Natalie! Let me know how they turn out! Happy thanksgiving.
Thanks so much Marilyn for these recipes. I just purchased a slow cooker and I want to make my Thanksgiving mashed potatoes in it this year as I have limited burner space. I’ve pinned your recipe and will give a try. Thanks also for hosting and have a very happy Thanksgiving!
Lisa, you are about to change the way you cook forever. That crock pot will make your home smell wonderful and have your meals ready when you are. I also love that when you have a few things cooking at the same time, you can cook and keep another dish warm. Since you can serve from the pot it also eliminates extra dishes! Enjoy! Happy Thanksgiving!
Slow Cooker mashed potatoes is genius! Why have I never thought of this?! This seriously makes my whole Thanksgiving so much better. Quick question though. Can I peel and store the potatoes somehow the night before I cook them or will it ruin the potatoes? Thanks!
Sure! I have put them in an air tight container no water. Then I rinsed them and dumped them in the crock pot. I do as much ahead of time as possible. Including setting the table! Enjoy.
I have to make these. Am a big fan of the slow cooker. Pinning! Over from Treats!
I know you will love these. My crock pot is plugged in all winter. I never go anywhere due to the cold so the OCD about have an appliance on all day doesn’t bother me as much! Have a good holiday!
Why have I never tried this? What a great way to get the potatoes done for that big holiday meal without taking up stove space or having to stand over the pan. Definitely trying this! I like my potatoes more rustic so I don’t peel and I fell in love with Rachael Ray’s mixins of bacon and roasted garlic I tried a few years ago so I’ll probably stick with that.
I am going to spice them up this. Bacon and garelic sound wonderful!!! And just a secret I leave the skin on to!
How silly that I never once thought to make mashed potatoes in a slow cooker. IT is a great idea. Thank you.
I only do it when my oven is in use and so are all 4 burners. And it uses less pots, too! Have a lovely week.
These recipes are right on time! They expand the options for handling extra guests at holidays. Thanks so much! Looking forward to trying these!
So glad I could help Pam! timing is everything. I am all for convenience and less cleanup! Have a lovely week!
Marilyn, I can’t mash the potatoes in my slow cooker because it has a Teflon-type coating, but I could cook them in it, dump them out to mash, and then return them to the slow cooker. Definitely want to try it. But no garlic for me, I’m allergic.
It sounds like a plan jean! Let me know how it turns out! Have a great day.
What a super easy way to make a dish that has always seemed to stump me just a bit. Thanks for sharing this with us at The Mommy Monday Blog Hop…
You are welcome. Tiffany. I am glad you like it! Happy Valentine’s Day.

Thanks for joining Cooking and Crafting with J & J!
Thanks Jess.Happy Valentine’s Day.
Marilyn, if there’s one thing we love in the winter it’s mashed potatoes! Warms you up and fills you at the same time. I’ve never tried them in a slow cooker, but this sounds like a great way to keep a burner open on the stove for other things!
I am so lazy. No frenzied after prerp, keeping them warm, or storing dish! I hit the jackpot this Thanksgiving! Happy Valentine’s Day.
I love anything I can prepare in the slow cooker!!!
I love mine for anything! Thanks Angela and have a great day!
Over the years I’ve made lots of things in my slow cooker but never mashed potatoes. Thank you!
It was truly genius at Thanksgiving. Dump them and forget them. Let me know if you try it!
Perfect for Thanksgiving and other holidays where I never seem to have enough burners. Thanks for sharing at Together on Tuesdays; Pinned!
My thinking exactly! Have a greatweek!
Looks so tasty! Visiting from #ThursdayFavoriteThings
Thanks Carol! Have a great week.
Your mashed potatoes look great. My Mom used to make hers on the stove and then keep them warm in the crockpot. If she only knew she could actually make them in the crockpot from the beginning. We didn’t know you then, too bad.
Hugs,
Bev
I just needed the stove space and also had too many “last minute” items so I threw them in there. I need to remember that treick for those big buffets! Thanks Bev.
Your mashed potatoes look so good. Thank you for sharing your recipe at the Snickerdoodle Create~Bake~Make link party!
Thank you so much Sharon! Have a great week.
Yum! These look great! I’ve never made slow cooker potatoes!! I can’t wait to try them!
Thanks Caitlin. They are great when you need the stove space or the last minute time!
This is the perfect comfort food for these cold winter days. Thanks for this great recipe Marilyn.
I am glad you found it useful Mary. I hope you had a great birthday!
I usually just make them on the stove because I am only cooking for 3. Well, my 8 year old usually eats enough for 2 so… Maybe I should try to make them in the slow cooker.
Thanks for sharing your tips on #FridayFrivolity
I liked the slow cooker option for Thanksgiving, etc. I have one oven and a split shelf so I gert the main dish and one side in it. Then I have 4 burners. The slow cooker doesnt require a burner, keeps them warm and no last minute prep. And it stores the potatoes right in it, so one bowl!! Otherwise I just make them on the stove at the last minute. The more I can do ahead of time, the happier I am! Thanks Audrey! Have a great week.
Sounds great – have a great week and Thanks for sharing on the What’s for Dinner link up!
Thank you Helen. You too!
