The Best Rich & Creamy Crock Pot Mashed Potatoes

With sour cream and cream cheese mixed in, these Crock Pot mashed potatoes are delicious, rich, and creamy. Thanks to the slow cooker, they are easy to make ahead and simply heat on the holiday morning - couldn't be easier!

You will not ever make creamier mashed potatoes than these. The sour cream and cream cheese make them smooth and creamy.

The very first time we ever made this recipe (on Thanksgiving day - always try the recipe before the holiday!), we made a giant mistake: we didn't pre-cook the onion, thinking that it would cook in the slow cooker. Unfortunately, that meant that our rich and creamy slow cooker mashed potatoes had crunchy raw onion in them.

Mashed potato fail.

We learned our lesson that Thanksgiving and always sauté the onions ahead of time.

And our onion-hating kids don't even know that these have onions in them because the onions sort of disappear.

How to use the slow cooker for mashed potatoes

You have two options here:

1. Prepare the mashed potatoes in the old way, by boiling and mashing them, then putting them in the Crock Pot to keep them warm on the morning of the holiday.
2. Cook and mash the potatoes right in the Crock Pot, drain, and then add the good stuff and use the slow cooker to keep them warm.

It doesn't matter which way you go. Both work really well. This mashed potatoes recipe is so awesome that you can't go wrong either way.

One additional note about using the CrockPot for mashed potatoes

When you put mashed potatoes in the CrockPot, they tend to get thick. Be prepared to thin them back out with half and half (plain milk will work in a pinch) and melted butter.

Ingredients

  

1x2x3x

• 3 pounds Yukon Gold potatoes cubed
• 4 oz low-fat cream cheese softened
• 4 oz low fat sour cream or Greek yogurt
• 3 oz evaporated skim milk ½ of a small can
• 1 small onion diced fine
• Salt & pepper to taste
• Milk & butter

Instructions

 

• Add potatoes to a large pot of water. Bring to a boil and cook until tender, about 15 minutes. Drain and mash.
• In the meantime, sauté onion in a small skillet until onion is translucent. If you skip this step, the onions will be crunchy in your finished potatoes, and nobody wants crunchy potatoes.
• In a medium bowl, combine cream cheese, sour cream, evaporated milk, cooked onion, salt, and pepper until blended. Add to mashed potatoes and mix well.
• Transfer mashed potato mixture to the crock pot. We use a 6-quart crock pot, and the potatoes half fill it.
• Can be cooked on low up to 4 hours. Re-moisten with milk and butter if needed.

Notes

Alternately, if you want to skip the boiling all together, you can add the potatoes to the slow cooker with plenty of water to cover them and cook on high for 4 hours or low for 8 hours. Drain and mash right in the crockpot, then proceed with step 2 as indicated above.
