Slow Cooker Mashed Potatoes
We love these for Sunday dinners or busy weeknights, and especially for Thanksgiving! Some of our favorite side dishes to serve along with these potatoes are Green Bean Casserole and my Grandma’s Famous Homemade Rolls.
Ingredients:
- Potatoes
- Water
- Salted Butter
- Milk
- Salt & Pepper
I like to use russet potatoes for this recipe. You can use new potatoes or Yukon gold potatoes instead, just make sure that you use 5 lbs. of potatoes.

How to Make Slow Cooker Mashed Potatoes:
Peel potatoes and chop into small chunks, then add them to your slow cooker.
Pour water into slow cooker and add 1 teaspoon of salt and a little bit of pepper.
Now, cook potatoes in the slow cooker on low for 6 hours or on high for 3-4 hours, until potatoes are soft.
As soon as potatoes are soft, mash them with a potato masher.
Add milk, butter, salt and pepper to taste. Taste as you go and add more milk until you get your desired consistency.
Pro Tips:
- Don’t over-mash your potatoes. Mash until they are soft and creamy, then stop.
- You can add other mix-ins to these potatoes. Some of our favorite things to add are sour cream, cream cheese, garlic, chives, dill, or rosemary.
Can I make mashed potatoes ahead of time and keep them in the crockpot?
Make ahead Mashed Potatoes
You can make mashed potatoes the day before Thanksgiving and re-warm them with great success.
Put them in a deep casserole dish and store in the fridge overnight. Warm them up in the oven the next day, uncovered, with a little butter on top.

Ingredients
- 5 lbs potatoes
- 1 ½ cups water
- 1/2 cup milk
- 1 ½ sticks salted butter (12 Tablespoons)
- salt and pepper to taste
Instructions
Slow Cooker Mashed Potatoes
- Peel potatoes and chop them into small chunks. Add potatoes to slow cooker and add water.
- Cook on low for 6 hours or on high for 3-4 hours.
- Once potatoes are soft, drain water. Mash quickly with a potato masher.
- Add milk, butter, salt, pepper, or whatever else you like to add to mashed potatoes and beat with an electric mixer until they reach your desired taste and consistency.
- Set your slow cooker to warm until you are ready to eat, then enjoy!
Make Ahead Mashed Potatoes
- After cooking, add an extra dose of milk and butter, so that the potatoes are kind of... soupy. This would not be ideal if you were eating them right away, but this will ensure that after being refrigerated, they will still be soft and creamy.
- Put them in a deep casserole dish and store in the fridge overnight. Warm them up in the oven the next day, uncovered, with a little butter on top.
- Transfer the mashed potatoes back into the slow cooker, and set it to low. Do this for up to 4 hours, stirring once an hour. Stir before serving. The mashed potatoes will stay warm and creamy.
Notes
- Don't over-mash your potatoes. Mash until they are soft and creamy, then stop.
- You can add other mix-ins to these potatoes. Some of our favorite things to add are sour cream, cream cheese, garlic, chives, dill, or rosemary.
