Slow Cooker Mashed Potatoes are beyond easy to make and are a side dish everyone will love.  They’re creamy and delicious, with the flavors of garlic, rosemary and tangy buttermilk!

Fall is only days away and I can hardly believe it.  At some point I’m going to have to put my shorts and flip flops away and start thinking about jeans and boots.  I really don’t want to, but I guess I have no choice.

Maybe some new fall boots will cheer me up?  Now that’s an idea.

With fall and cooler temperatures on the horizon, my mind is definitely headed into comfort food zone.  The prospect of soups, chili, and cozy autumn suppers is enough to make me excited about fall.

Even more so than new boots!

Potatoes are one of my favorite comfort foods and I make them at least once or twice a week.  Naturally they’re great in the summertime (hello potato salad and foil packets!), but I love them even more in the cold months when I crave good soul-warming food.

What I love most about potatoes is that they’re a blank canvas of unlimited possibilities.  They can be baked, roasted, or fried, and they’re amazing in soup.  They’re so versatile that they can be enjoyed for breakfast, lunch or dinner.

Potatoes are beyond convenient too.  They’re perfect for any occasion whether it’s an elegant dinner party, holiday, brunch, or game day celebration.

Everyone loves potatoes!

The most requested potato dish in my house is mashed potatoes, which is normally the last potato dish that I want to prepare.

Please don’t think that I don’t love mashed potatoes because I do.  The problem is that they can be high maintenance and I just don’t want to deal with that most of the time.

That’s where these Slow Cooker Buttermilk Mashed Potatoes come in.  All you have to do is peel the potatoes, chop them, dump them into the slow cooker, and forget about them for a few hours.

Once they’re tender, simply mash them with a potato masher right in the slow cooker!

The potatoes in the photo above are yukon gold potatoes, which are the only variety that I use for mashed potatoes.  You can certainly use russets, but if you’ve never tried yukon golds I encourage you to do so.  They have a wonderful creamy texture that’s perfect for mashed potatoes!

The buttermilk makes these Slow Cooker Buttermilk Mashed Potatoes special because it gives them a delicious tangy flavor.  I chose to keep my mashed potatoes on the lighter side, so I used low fat buttermilk.  If you prefer your mashed potatoes to be on the richer side, use full fat buttermilk, or even substitute a portion of the buttermilk with whole milk or heavy cream.

These Slow Cooker Mashed Potatoes are going to make my life so much easier on Thanksgiving, Christmas, and any time my family asks for them.

Good-bye high maintenance mashed potatoes!

Recipe Notes:

• All slow cookers are different, so the first time you try making mashed potatoes in your slow cooker you should keep a close eye on them.  I suggest checking for doneness after 3 hours on low and even stirring them occasionally.  Also, add a bit more liquid if it evaporates too quickly.
• I’ve only cooked my potatoes on low and wouldn’t advise cooking them over high heat unless you’re prepared to check them often to prevent scorching.
• Warm the buttermilk prior to adding to the hot potatoes to prevent curdling.  It should be a bit warmer than lukewarm, not hot.
• Customize this recipe to your liking — anything goes!
• The best way to keep mashed potatoes warm without the risk of scorching them is the bain marie method.  Simply place them in a heatproof bowl or pot, cover, and place over a pot of gently simmering water.
