Why you'll love them

These slow cooker mashed potatoes are creamy, buttery, thick, restaurant-style mashed potatoes. I would not describe them as light and airy, and we wouldn't have it any other way! They're destined to be the star of your Thanksgiving or Christmas feast and are equally fabulous for potlucks or any old dinner, honestly.

It's worth it to cook mashed potatoes in the Crockpot since it frees up valuable stovetop space when you're cooking a big meal or need an easy side dish. They're also super simple to make since they're no-boil and no-drain mashed potatoes. Your slow cooker does most of the work, and you mash them right in it without any hassle!

What you'll need

Potatoes - the classic varieties for mashing are either Yukon Gold or Russets. They're starchy, meaning you'll get the correct texture and they won't end up gummy.
Chicken broth - it adds another savory dimension and is a great way to keep in the moisture, especially if you're not serving them for a few hours. Use vegetable broth if you need these to be vegetarian.
Salt - it's important to be generous to bring out all the flavors
Heavy cream - for that indulgent richness
Butter - mashed potatoes is one place where butter is a must!
Garlic - mincing garlic cloves with a garlic press makes it way easier since it's fast and you avoid sticky fingers. You could leave it out if you're not a garlic fan, though.

Can I use an electric mixer?

I wouldn't recommend it. Using a good old-fashioned handheld wire masher ensures you won't overwork the potatoes. Nobody likes gluey mashed potatoes, so I make sure I can control the consistency and texture! Plus you don't have to clean up more appliances.

How to make slow cooker mashed potatoes

This is an overview, and full ingredients & instructions are in the recipe card below.

To your Crockpot, add the broth and salt. Set the temperature to high. Meanwhile, clean and chop the potatoes, then place in the slow cooker and stir.
Cook on high for 3 to 3.5 hours until soft. Our kitchen hasn't tested, but 6 to 8 hours on low should work fine, stirring a few times for even cooking. When they're about ready, add the cream, butter, and garlic to a small saucepan and heat until warmed through.
Slowly pour it into the Crockpot while mashing the potatoes, taking care to not overwork them. There's no need to drain any excess broth. Season with extra salt if needed. Set it to "keep warm" until ready to serve!

Substitutions and variations

You can use red potatoes if that's all you can find, but be extra careful to not to over-mash them since they're a waxy potato and generally not the best for this.
If you want to substitute the cream with half-and-half or milk, you can, but mashed potatoes are the place to go all-out, and real cream can't be beat. The taste and texture just won't be as rich with a lower fat alternative. I wouldn't recommend skimping on the butter either.
Feel free to peel the potatoes if you prefer. I often like leaving the skins on for a more rustic texture and variation. Just make sure to scrub them well if you go that route.

What to serve with Crockpot mashed potatoes

You can garnish with fresh chopped scallions, chives, or parsley if desired along with an extra pat of butter. Freshly grated parmesan? Why not!
For an easy complete meal, pair them with Smothered Chicken or Creamy Bacon Pork Chops and a veggie like Easy Roasted Green Beans.

Leftovers and storage

If you plan on eating these mashed potatoes the same day, I recommend keeping them in your slow cooker on the "keep warm" setting. Just give them a stir prior to serving, and you'll be good to go.
For the next day or even the day after that, you can either reheat them in the Crockpot or in a covered pot on the stove over fairly low heat. Once they're warm, I re-mash them and add a bit more butter and cream to bring them back to their former glory.
I don't recommend freezing mashed potatoes.
