No-Boil Slow Cooker Mashed Potatoes

Slow Cooker Mashed Potatoes are a holiday favorite of ours since we bought our first slow cooker together. In fact, it was the second slow cooker recipe I ever made (first was: Ultimate Slow Cooker French Dip Sandwiches).

The best part about the recipe is that it doesn’t need ANY boiling. It is as easy as dump and cook, then a quick mash with a potato masher or hand mixer and you’ve got delicious mashed potatoes!

Can you make mashed potatoes in a crock pot?

Absolutely. Crock Pot Mashed Potatoes are as easy as any other dump and cook meal. The hardest part is peeling the potatoes!

How long can I keep mashed potatoes in a crock pot?

I have successfully kept slow cooker mashed potatoes warm and covered during events for up to 4 hours before noticing any noticeable drying out.


Stovetop Mashed Potatoes:

Cook the potatoes in water instead of vegetable stock, then add in the rest of the ingredients once they have become tender (10-12 minutes) and drained. I also add a bit of heavy cream to make them extra luxurious sometimes.

Mashed Potatoes


Potatoes are heavier than they look, so account for half a pound of raw potatoes per person/serving when considering how much mashed potatoes you have to make.

As a general rule bags of red potatoes are sold in 3lb. packages while russet potatoes are sold in 5 and 10 pound bags. Remember red potatoes won’t be peeled so you don’t lose the weight of the potatoes while russet potatoes will lose at least 5-10% of their weight in preparations.

  1. My family loved these mashed potatoes last night! I love the simplicity of throwing everything in a crockpot and not using an extra burner on the stove, especially when its summertime. These were so easy to make and had excellent flavor! I halved the recipe and used chicken broth I had on hand. Also used a tiny bit of almond milk to help with the mashing since I don’t have an immersion blender. So yummy!!

    1. It might make the slow cooker overcrowded and not cook evenly. I’ve only tested it using a 3 qt so I’m not sure if it would be ok or not. If you decide to try, I’d love to know how it turns out. Thanks!

  2. This looks like an amazingly timesaving recipe – we’re having about 25 for Thanksgiving. Would this recipe work well doubled in a 6qt slowcooker?

  3. I am curious. In your instructions it’s refers to red potatoes and russets, yet, in your recipe you use Yukon potatoes. Do you peel Yukon potatoes or leave them with the skin on?

  4. Hi. I just found this wonderful recipe. If all i have is a5 qt crock pot, would i make 1 and 1/2 times the recipe? Thanks.

  5. I couldn’t get the crock pot mashed potatoes or the 1 hour cinnamon rolls to print. I noticed that both of these recipes had the “print recipe” button in a different place than the Mongolian Beef and the Chipotle barbacoa Beef recipes, which printed with no problems.

    1. Sorry it took me a bit to respond to you but it looks like the issue has been resolved. I just tested both and was able to print with that button. Thank you for letting me know and sorry for the inconvenience.
