Is it too soon?

Too soon to be bringing you roasted garlic mashed potatoes that are perfect for your Thanksgiving tables. Okay, maybe it’s just a tad bit too soon.

And maybe, just maybe i’ve gotten a little too attached to my slow cooker lately. I mean, if you follow me on SNAPCHAT (littlespicejar) you totes saw that snap where I had not one but TWO slow cookers running at the same time, cooking up a storm without even firing up the stove. I admit, i’m collecting these badboys like it’s nobodies business. This is the third addition to my slow cooker family and it’s such a great size. I had a tiny one that was perfect for quick dips and what not and my other one was huge! It’s a 7 or 8 quart (can’t remember) but it’s the one I use for when i’m making a big batch of this this or this. This 3 quart is perfect for small batches of soup and also SIDES!

And what better way to welcome this guy then to make GARLIC MASHED POTATOES. YES!

Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (2)For my roasted garlic mashed potatoes, I roasted the garlic myself. And i’m totally not judging if you want to buy store-bought roasted garlic cloves, that’s fine by me! But just know that you are kinda sorta missing out on the best part of roasted garlic – also known as, the smell.Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (3)Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (4)Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (5)

And roasting garlic at home is really easy to do! You can do it in your regular oven or a small countertop toaster oven. I typically roast a few heads of garlic at once and then stash them in the refrigerator for things like –>this SOUP.

Grab a couple heads of garlic and slice off the pom-pom looking this at the top. This will help peel back the paper. Leaving the head intact, gently rub and remove as much of the paper as you can. Place the garlic heads in a large sheet of foil and drizzle 1 tablespoon of olive oil for every 2 heads of garlic. And give them a good sprinkling of salt and pepper. Wrap up the foil and place it in a 375º oven for 1 hour. Now sit back and let the smell take over. It’s slightly disturbing how much I love the smell of roasted garlic.

Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (6)I let my garlic mashed potatoes cook for 7-8 hours on the low heat setting and I didn’t even need to cut them in half. If you’re going to cook them on the high heat setting for 4-5 hours, keep in mind you’ll need to chop them in half so that theyblend easily with a hand blender.

Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (7)Add in the cream and let start the hand blender. Careful not to place the blades on the surface of the crockpot or you might have flying mashed potatoes!

The amount of cream you add is completely up to you. You can add as little as ⅓ of a cup and all the way up to ½ a cup (which is what I did). Keep in mind these mashed potatoes are completely rustic with bits of skin and lots of little teeny tiny lumps throughout. For super smooth mashed potatoes, cut the potatoes into smaller pieces, cook on the low heat setting for 7-8 hours and blend with ½ cup of heavy cream. They’ll be unforgettable, I promise you!Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (8)

Learn how to make roasted garlic mashed potatoes in the slow cooker. This recipe is quick and easy and makes the creamiest mashed potatoes that are flavored with fresh herbs right in the crockpot!

Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (9)

Ingredients

  • 2 lbs. Red potatoes, cut into 1 ½ inch pieces
  • 1 teaspoon fresh thyme
  • 1 head roasted garlic (12-15 cloves) (see notes)
  • ¼ cup (4 tablespoons) salted butter
  • 1 ½ teaspoon salt
  • 1 teaspoon black pepper
  • ½ cup vegetable or chicken broth
  • ⅓-½ cup heavy cream (to preference)
  • 1 tablespoon chopped parsley

Instructions

  1. Spray the inside of a three-quart slow cooker with cooking spray. Add the potatoes, thyme, roasted garlic cloves, butter, salt, pepper, and chicken broth. Cover and allow the slow cooker to cook for 4-5 hours on high or 7-8 hours on the low setting.
  2. Add the heavy cream to preference. Start with⅓ cup and if you want the potatoes to be more creamy, add the full ½ cup. Keep in mind, the heavy cream can be replaced with regular milk but it won't make the mashed potatoes creamy and rich. Use a hand mixer to blend the potatoes or a potato masher can be used for a more rustic mashed potato. Careful when blending, mix on the slow speed and don't let the blades get too close to the base of the crockpot. Season with additional salt and pepper to taste. Sprinkle the parsley and fold before serving.

Notes

  • how to roast garlic:Preheat an oven (or countertop oven) to 375ºF. Chop off the tip of the garlic and peel off as much paper as possible without breaking the garlic head. You want the garlic cloves to be exposed when you chop off the top. Drizzle with ½ tablespoon olive oil and sprinkle with salt and pepper. Wrap the garlic head in foil and roast in the oven for 1 hour. Additional garlic heads can be roasted together in the same piece of foil.
  • Please keep in mind that each slow cooker is different. If you know yours runs a little hot/cold, adjust the cooking time for the mashed potatoes accordingly.

    Thank you so much for this! It’s been an incomplete thought in my head for so long and now I have a recipe to try!

    You show the potatoes whole in the crock pot, but the recipe says to cut them in cubes. Please advise. Thanks for this nifty recipe!

      Barbara, I tried the recipe both ways (some of the pictures are from trial #1) and though either way will work, I prefer the potatoes being cut into cubes. This allows more even cooking of the potatoes and it’s much easier to blend 🙂

    I’m wondering how big the crock pot was that you used; I’m considering doubling the recipe in my 5 quart and wondering if it would be big enough to hold it all!

    • Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (17)

      Marzia Reply

      I used a 3 quart crock pot. Your 5 quart should be able to hold a double batch of this recipe, but you may need to just blend and add the cream in a larger bowl or something. Not too sure if there would be enough room for almost 1 cup of cream and for your beaters.

    What are your thoughts on Yukon Gold potatoes for this recipe?

      Yukon Golds would be great for this recipe, even a big old russet potato would do! 🙂

    Can you peel them prior to cooking? My husband doesn’t like the skin.

    Hi! I am just wondering if I could do this the night before I cook them and let them sit in the fridge overnight? If so, should I wait to add the liquid until the morning or anything?
    Cooked these for Thanksgiving and they were a HUGE hit! This is my 2nd time making the recipe!

    • Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (25)

      Marzia Reply

      You can make the mashed potatoes the night before. I’d add the liquid when the potatoes are still warm and complete the recipe. When reheating, just add a bit more milk/ melted butter to bring back to desired consistency. 🙂 Happy to hear they were a big hit!

    Karen Reply

    Would love to try these, as I’ve never made mashed potatoes in a crock pot before. However, if I wanted to make say 5 lbs. of potatoes instead of 2 or 3, what would I do just add more garlic, butter, chicken broth, cream, etc. to the recipe? It would be nice if you posted instructions for 5 lbs. of potatoes. I have a large family and we need more than 2 lbs., lol!! Also, would the cook time be the same if it were more potatoes? I don’t use my crock pot often.

    • Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (27)

      Marzia Reply

      You can simply triple the ingredients to make the amount you need (i.e. 6 lbs. of potatoes, 3 teaspoons thyme… etc.). The cooking time will be the same and you’ll need a 7-8 quart crock pot. Hope you enjoy the mashed potatoes, Karen!

        Thanks!!! I don’t know the size of my crockpot, but will check it soon, lol.

    WOW! I just made this for tomorrow’s Thanksgiving feast and I HATE making mashed potatoes. This was easy and full of buttery garlic goodness. Thank you for this rustic spin on the mundane, yet necessary traditional side. I just hope this reheats well, any suggestions would be greatly appreciated. Also, I am glad I doubled the recipe!

    • Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (30)

      Marzia Reply

      They reheat beautifully. I just pull them out of the refrigerator a few hours before dinner time and then reheat them in the microwave for a few minutes before serving. You may need a little additional milk to thin them out as potatoes tend to thicken as they rest. Hope everyone enjoys them Angela! 🙂

    Does using a hand mixer make the consistency gluey?

      You can also use a potato masher if you’re worried about the consistency.

    Do you put the garlic cloves in whole? Or chop them first?

      I put the roasted garlic cloves in whole as it’ll all be blended at the end. Totally your call though!

    Happy Thanksgiving everyone! I’m making these in my crockpot now – doubled the recipe as we have a lot of people to feed. Hoping I can get a quick response buuuuut thinking it’s not likely in Thanksgiving day lol. Do you drain off the chicken broth before blending and adding the cream?

    • Slow Cooker Roasted Garlic Mashed Potatoes Recipe | Little Spice Jar (37)

      Marzia Reply

      Hi Emily! Happy Thanksgiving to you too! If you’ve got a ton of broth leftover, then yes, I’d suggest draining it. If it’s half of what you started with or less, it’s your call. I personally like the broth as it gives it a good flavor, but you can certainly drain it and add milk/half and half to your liking! 🙂

    Great recipe! Roasted garlic is such a wonderful thing. I’ve made this a few times and sometimes I get a little sinful with it and add a bit of cream cheese at the end.

    Made these Many Times, doubled and even tripled the recipe. This is now one of those ‘special day’ requests in our home (making for our eldest today, at his request for his birthday dinner!) It’s very easy (crockpot!). The recipe is Very Forgiving (no fresh thyme? Dried works!) Taters too dry or too starchy? …add broth, milk, or cream! Rustic charm? …don’t peel! Skin hater/picky eater?…then peel! They reheat well. They travel well. They make the whole house smell Fabulous. And they present well for ‘Fancy’ occasions (Thanksgiving, dinner parties, etc) Fabulous ‘keeper’ recipe at our house!
    (Pro Tip for extra special days…fold in Sharp Cheddar or Colby shreds at the end!)

FAQs

How do you keep mashed potatoes moist in a slow cooker? ›

The lowest setting of your slow cooker will keep the potatoes nice and warm without drying them out. If you notice that they are getting a little dry, loosen them up by stirring in an extra splash of milk or cream or a few tablespoons of butter.

How do you keep garlic from burning when roasting potatoes? ›

I find crushing the garlic and tossing it with the oil and mustard helps prevent it from burning. If you find your garlic burns easily when roasting, you can always chop the garlic cloves into larger chunks! Why do I need to dry my potatoes before roasting?

Why add nutmeg to mashed potatoes? ›

A little bit of nutmeg adds flavour and interest to classic mashed potatoes.

Will potatoes overcook in slow cooker? ›

Be careful not to overcook the slow cooker baked potatoes, because they will become tough and even possibly burn. That's it! You'll have delicious Crock Pot roasted potatoes in virtually no time or effort. Now that you know how to bake potatoes in a Crock Pot, grab a fork and dig in!

How do restaurants keep mashed potatoes fresh? ›

How do you prevent botulism in roasted garlic? ›

To reduce the risk of botulism, the garlic in oil mixture should be refrigerated and used within four days. Garlic in oil should always be discarded after two hours at room temperature, even if salt and acids are present.

Does garlic seasoning burn? ›

(Garlic powder can still burn, but it is less likely to do so than fresh.) Raw garlic also should not be used in sous vide cooking because there's a risk of botulism.

How do you roast garlic so it doesn't burn? ›

The same goes for roasting garlic, by the way. A whole head of garlic that's been halved, rubbed with oil, and wrapped in foil then baked in an oven turns sweet, creamy, and spreadable. But keep the temperature no higher than 375˚F, or the outer edges will burn before it has time to soften.

Why add baking soda to mashed potatoes? ›

Just a pinch of baking soda is all you need to create mashed potatoes as soft as clouds. When you add baking soda, it reacts with the heat of the dish and the acid in the milk or cream to create small air pockets throughout the mash. These air bubbles translate to light and airy bites. Yum!

Why do you put baking soda on potatoes? ›

Meanwhile, the alkaline water helps the exteriors of the potatoes break down more, creating much more of the starchy slurry that leads to an extra-crisp exterior. About a half teaspoon of baking soda for two quarts of water was the right amount.

Why do restaurant mashed potatoes taste better? ›

Garlic and herbs are added to boost flavor

Instead of boiling a few potatoes and mashing them plain, a lot of restaurant chefs like to apply a little more finesse. Garlic and herbs infused in butter and cream add a flavor boost without overpowering.

What adds flavor to mashed potatoes? ›

Garlic – For savory depth of flavor. Unsalted butter – For richness and buttery flavor. Milk – It smooths the starchy potatoes into an incredibly creamy mash. Use whole milk for the creamiest results.

How do you keep mash from drying out? ›

Probably the simplest is to place the mashed potatoes in a heat-proof bowl over a pot of simmering water. You can cover the bowl with foil, or use a lid that fits over the bowl. Make sure the water doesn't burn dry, and never gets above a simmer—and that's it.

How do you soften potatoes in a slow cooker? ›

Prick potatoes with a fork several times, then rub with olive oil and season with salt. Wrap tightly in foil and place into the slow cooker. Cook until tender, on Low for 7 1/2 hours or on High for 4 1/2 to 5 hours. Serve with your choice of toppings and enjoy!

How do you get moisture out of mashed potatoes? ›

Try draining the cooked water off in a sieve or colander and then placing back on the stove to cook out some of the extra moisture, just a couple of minutes. Mash with a masher (or a ricer which makes great non lumpy spuds). Always add melted butter or the liquid when it is warm and do this a little at a time.
