Do you love sour cream and onion potato chips? These Slow Cooker Sour Cream and Onion Mashed Potatoes are even better! I use creamy Yukon gold potatoes, those cook with onion, garlic and water. After the cooking time is up I drain the water off and add butter, sour cream, and more onions!

These potatoes are great with just about anything! My favorite is chicken or steak, but salmon would be great too!

Slow Cooker Sour Cream and Onion Mashed Potatoes

Prep Time: 25 minutes
Cook Time: 5 hours
Total Time: 5 hours 25 minutes
Servings: 12
Rich and oniony potatoes that go good with just about anything!

Ingredients 
 

  • 5 lbs. Yukon gold potatoes,, peeled and diced
  • 1 cup white onion,, minced
  • 2 garlic cloves,, peeled
  • water to cover
  • 1 tsp. salt
  • 1/4 tsp. pepper
  • 1/2 cup salted butter
  • 16 oz. sour cream
  • 1 bunch green onion, sliced
  • 1/4 cup chives

Instructions 

  • Add the peeled and diced potatoes to the slow cooker. Add the minced white onion, garlic cloves and add water to cover.
  • Add the lid to the slow cooker. Cook on high for 5 hours without opening the lid during the cooking time.
  • When the cooking time is up, Drain the water off. I do this by using 2 pot holders and a spoon to hold the potatoes back, and pour off the water down the drain, it’s tricky but can be done. Or you can dump the potatoes into a colander. 
  • If you see the garlic cloves, remove them. I had a hard time getting them to blend up.
  • Add the stick of butter and bury it down in the potatoes to melt. Add the sour cream, salt and pepper. Using a mixer, blend the potatoes until smooth. You can use a potato masher and mash by hand if needed. Stir in the sliced green onion and chives.
  • Serve and enjoy!

  4. Petra Kunkler says:

    I would recommend to just mash the Potatoes, so you still have a bit of Chunks in it, but that’s only my Opinion, since we do it like this in Germany.

  5. Sherry Lee says:

    Take it up another notch, serve with french fried onions on top! The ones you can buy in the store
