Make Ahead Roasted Garlic Mashed Potatoes, the best holiday mashed potatoes side dish. Made simply with sweet roasted garlic, fresh herbs, and salted butter. Each bite is perfectly smooth, creamy, and so delicious. The secret? Cooking the potatoes together with the milk and cream, then adding in roasted garlic cloves for a delicious garlic flavor that isn’t overpowering. This method makes for the creamiest and most flavorful mashed potatoes. Theyâre perfect to make-ahead of time for easy entertaining, especially for Thanksgiving and Christmas!
Two things… first, the roasted garlic. Roasting the garlic adds just the right amount of garlic flavor that’s delicious but not over powering.
Second, cook the potatoes together with the milk and herbs. This means no boiling the potatoes, no extra steps, nothing fancy. It turns out that creating almost perfect mashed potatoes is actually really easy.
Start with the garlic since it takes time to roast in the oven. If youâve never done it before it really adds a layer of deliciousness to your recipes.
Simply slice the top portion of the garlic head off to reveal the cloves. Then place the garlic on a small piece of foil, drizzle with olive oil, and wrap the garlic up. Roast for about forty minutes, until the garlic is deeply golden and soft.
Then simply squeeze the cloves out of the garlic skin.
Combine the Yukon gold potatoes with the milk and cream in a large pot on the stove. Add the herbs, then cook until the potatoes are tender. This will take about twenty-five minutes or so. Once the potatoes are cooked, drain them, BUT, be sure to save the cream – youâll need it!
Now, the potato ricer…itâs key to making ultra-smooth mashed potatoes. Do you have to have a potato ricer? No, a good ole masher works too. But if you want the smoothest mashed potatoes, a ricer works really well.
Take the mashed potatoes and those roasted garlic cloves and put them right back into the pot. Then add back the cream and also add some butter. Cook until the butter is meltedâ¦and thatâs it…the most perfectly flavored creamy mashed potatoes!
Honest these are the BEST – classic, but with amazing flavor and texture. You will definitely want these along with your turkey and gravy!
The added bonus is just how easy these are to make…and that you can make them ahead of time. Steps for warming in the oven, slow cooker, or on the stove are listed in the directions!

Super easy, super delicious (AND a money and time saver). I wasn’t trying to cut corners or cut out steps, but my potatoes didn’t need draining and with a few big, firm stirs they pretty much “mashed” on their own in the pot (we like it a little chunky). I added the butter and garlic, a touch of S+P and boom, fantastic side to ribeyes with mushrooms and onions. Thank you!
Hey Audra,
Awesome!! So glad to hear this recipe was enjoyed. I appreciate you giving it a try and your feedback! Have the best day! XxT
I am bringing this to a Friendsgiving and we have someone who is vegan, so I would love to be able to make this vegan so she can enjoy them. Do you know what I could substitute the heavy cream and whole milk for?
Hi Alicia,
You could use a coconut cream and dairy free milk! Please let me know if you have any other questions! xT
The best garlic mashed potatoes ever!
Hey Karen,
Love to hear that this recipe turned out well for you, thanks for sharing your notes! Have a great fall weekend! xT
I am Pamâs grandmother and I have the recipe now. I hope mine are as good as hers were. ð¹
This is THE mashed potato recipe. I made these two days before our Christmas meal and followed the oven reheat instructions. Couldnât have been more convenient or delicious. My grandmother said they were the best mashed potatoes she had ever eatenâhigh praise, especially for something so simple!
Wow thank you SO much Pam! Love to hear that! ð xT
I made this recipe for Christmas dinner and everyone loved it! Iâm a 21 year old and it was my first time bringing a dish and everyone genuinely loved it! I put the garlic in the air fryer instead of the oven at the same temperature for about 35-40 min and it cooked well.
Thank you so much for giving this recipe a try! Hope you have an amazing New Year! ð xT
Cant wait to make these…if I’m serving short ribs on top of the potatoes, am I better off making them right before serving?
Kathy
Hi Kathy! Yes, I would definitely make them right before ð xT
This is the best and only way I will ever make mashed potatoes again! I served them at Thanksgiving and my brother loved them so much he said I nailed it! High compliment coming from him. Thank you Tieghan!
Hey Brooke! I’m so so glad you enjoyed this recipe! Thanks for giving it a try! xT
Iâve made before and they are always amazing! I donât usually make ahead, but this holiday Iâd like some time freed up. How many days ahead can these be made?
I would like to try the Roasted Garlic Mashed potatoes. Can someone tell me how to drain the milk but keep the cream?
I think the word cream in that step of recipe includes the milk. We put a strainer over a bowl and drained. These potatoes were a huge success and worth every step
These turned out so delicious that my MIL asked to take a bowl home! Also so delightful to have in the fridge ready to go with so many other Thanksgiving items to prep day of. Thanks for a tasty and useful recipe!
Hi Cady,
I love to hear that this recipe turned out well for you, thanks for making it and your review! Happy Sunday! xT
These are absolutely hands down the best mashed potatoes Iâve ever eaten!
Used the crockpot to keep them hot all day which was a game changer and space saver!
Thank you!!!
My family didnât want to use gravy on them bc they said they were so perfect as is and didnât want to change them! haha
Hey Erin,
Thanks for making this recipe and your comment, so glad it was enjoyed! I hope you had a wonderful Thanksgiving! xx
This is no joke! Straight up the best mashed potatoes Iâve ever had!!!
Hey Scott,
Happy Thanksgiving! Thanks for making this recipe and your comment, so glad to hear it was a hit! xx
I have prepared my mashed potatoes. Can I now roast the garlic and fold in tomorrow with a bit more milk and butter or is it too late for the roasted garlic?
ALSO, how long does it take to reheat the next day in the slow cooker. I am serving at 4:00, thinking putting them on low at noon.. thoughts??
Lisa, I’m sorry! Folding in the garlic the next day worked perfectly for me. Can’t speak to reheating, but knowing how finicky mashed p’s are when reheating, it will take longer than you expect. Happy Thanksgiving! I am thankful for fellow HalfBaked-ers like yourself.
The video showed using an Instapot to cook the potatoes. How long do you cook them for?
Can you substitute rosemary for the sage and would 2 heads of roasted garlic be too much? We like a lot of garlic.
Hi Lisa,
Sure, that would work for you! Noon sounds great! Happy Thanksgiving! xT
