Slow Cooker Creamy Garlic Mashed Potatoes

Creamy, garlicky, perfect mashed potatoes, made in the slow cooker! This means less hands-on work for you, making this crockpot mashed potatoes recipe perfect for holiday meals or a meal prep side.

I’m a big proponent of using your slow cooker as a meal prep powerhouse.

You mean, I just have to throw in some ingredients, turn the thing on, and it does the work for me?

Yessss, lady! #praisehands

Finding time to get meal prep into an already busy week is tough enough.

But the crockpot makes light work of that, and these creamy, dreamy mashed potatoes prove that.

Big chunks of peeled potatoes are cooked with whole garlic cloves, a little bit of water and butter, and salt. THAT’S IT.

Then you let those flavors come together sloooowwwwlly, before whisking in milk at the end and mashing everything up.

It makes for a great hands-off holiday meal side, meal prep side, “I’m-in-love-with-mashed-potatoes-and-I-don’t-care-who-knows-it” side.

You do you, honey boo.

And then throw some potatoes in a crockpot and forget about them for a while.

Prep Plan

Prep it for later:
1. Peel potatoes and slice into large chunks.
2. Lightly smash garlic cloves to break up the skin, which then gets discarded.
3. Combine the potatoes and garlic in a large resealable bag or container. If using a bag, press out as much air as you can to avoid any discoloring of the potatoes.
The chopped potatoes will last for about 2 days in the fridge. Some discoloration may occur, but will not affect taste.

You’ll need:
1 bar or container of chopped potatoes and garlic

Prepare from prepped:
1. Combine the chopped potatoes and garlic with butter, salt, and water to the slow cooker.
2. Cook according to the instructions in Steps 4-6
