Make a big batch of these slow cooker mashed potatoes for your dinner or even holiday get-together. This is a classic flavored recipe that is great alongside turkey or ham.
If you have two slow cookers try either my brown sugar ham or my turkey breast recipe in your other slow cooker.
Why this recipe works
This no-boil mashed potato recipe is perfect when you need a hands-off side dish. The slow cooker cooks the potatoes while you are busy with other tasks. Just drain and add in butter and heavy cream!
Making mashed potatoes in a crockpot is perfect for the holidays, parties, or buffets for the slow cooker will keep the potatoes warm until everyone is served. If you are looking for an Irish version try Colcannon potatoes (made with the addition of cabbage!).
How to make mashed potatoes in a crock pot:
Here is my classic and easy recipe for mashed potatoes in the slow cooker. I use only a few ingredients in this recipe. This recipe is similar to Martha Stewart’s mashed potato recipe though in a relatable slow cooker recipe.
Ingredients
- Potatoes – I use russet for this classic recipe.
- Water – Enough to cover, don’t fill your slow cooker to the brim or it may overflow while cooking.
- Heavy whipping cream – Can use whole milk, half and half, or regular whipping cream if needed.
- Salted butter – don’t use margarine
- Salt (and Pepper) – I do not add pepper when I’m serving to a group, many do not like pepper and the potatoes look great all white for holiday entertaining. I do add pepper when it’s just my little family.
Step-by-Step Directions
Step One – Peel your potatoes. Rinse them, then dice them into 1/2 inch to one-inch cubes. You really want to make sure there is no dirt on the potatoes. Add the potatoes to the slow cooker.
Step Two – Along with the peeled potatoes in the slow cooker, add enough water to cover.
Step Three – Place the lid on the slow cooker. Cook on HIGH For 4 hours.
Step Four – After the cooking time is up, drain off the water.
Step Five – Add a stick of butter to the hot drained potatoes. Use a handheld mixer and blend right in the slow cooker. Be careful not to scrape the mixer on the bottom or edges. You may need to use a spatula to pull up the potatoes from the bottom occasionally. Add the heavy cream, salt, and pepper. Continue blending until light and fluffy. DO NOT OVERMIX, or they will turn gluey. You can use a potato masher if you don’t have a hand mixer.
Variations
This recipe is just a base for whatever your heart desires. Try one of these fun and delicious variations.
- Cheesy – Add 1 cup of sharp cheddar cheese to the potatoes and top with 2 more cups of cheese. Place the lid on top and let the cheese melt for 10 minutes.
- Loaded Mashed Potatoes – Serve the potatoes buffet style with bowls of cheddar cheese, bacon, green onion, and sour cream on the side for guests to serve themselves.
- Velveeta Cheese – Cut the heavy cream in half in this recipe. Add 8 ounces of velveeta cheese and mix in. Then top with the remaining velveeta cheese (cube it small and spread it out). Let melt for 15 minutes.
- Lower fat – Cut the butter in half. Omit the heavy cream and use fat-free milk in its place.
- Garlic – Add 1 teaspoon of garlic powder while blending the potatoes for a garlic punch!
Recipe FAQs
You can add a box of cream cheese to this recipe instead of heavy cream if desired. You will need to add a splash of milk to thin out the potatoes.
2-3 hours, stirring often. Add extra cream, milk or butter if they start to dry out.
If you are short on time or love mashed potatoes with skins on you can leave them on! Be sure to scrub your potatoes well before dicing (especially russets).
Yes, you can use gold or red potatoes in this recipe. Be sure to cut them in half-inch cubes, if cut too big they will take longer to cook.
Keep your potatoes covered with water while prepping. Add some water to the slow cooker while you dice your potatoes. Only cut 2 potatoes at a time, rinse off the dirt, dice and add to the water in the slow cooker. This will keep them from browning.
Potatoes and cream change after being in the freezer. Potatoes get grainy and cream separates. I do not recommend freezing mashed potatoes.

Slow Cooker Mashed Potatoes
Equipment Needed:
Ingredients:
- 5 lbs. russet potatoes
- water to cover potatoes
- 1/2 cup salted butter (1 stick)
- 1 1/2 cups heavy cream (can be labeled heavy whipping cream) can use regular whipping cream or whole milk
- 2 tsp. sea salt
- 1/4 tsp. pepper (optional) I do not use pepper for the holidays. I prefer creamy and fluffy white mashed potatoes for serving to guests.
Instructions:
- Peel the potatoes. Be sure to rinse off any dirt that is left on the potatoes after peeling. Cube into 1/2-1 inch pieces. Add to the slow cooker.
- Pour over water to cover the potatoes but do not fill water to the brim of the slow cooker, at least leave an inch.
- Place the lid on the slow Cook on HIGH for 4 hours.
- When the cooking time is up, drain the water off the potatoes. I do this with 2 potholders, using the lid to hold the potatoes in, but leaving a crack for the water to come out.
- Add the stick of butter to the drained potatoes. Bury it into the potatoes while you set up a handheld mixer. Blend the butter into the potatoes on medium speed, then add the heavy cream, salt and pepper (if you are using it). Blend until smooth and fluffy. Add additional cream (or milk) if needed. (Be careful not to scratch up your slow cooker with the mixer, avoid hitting the sides or bottom with the beaters). You can use a potato masher if you do not have a hand mixer.
- Taste and see if you want to season with additional salt.
- Serve and enjoy!

Can chicken broth be used as a substitute for water?
Yes, that would work great.
So easy and so delicious! Everyone loved it for Easter
This was excellent I will definitely make this again. Thanks for the recipe.
Best mashed potatoes I ever made in the slow cooker. Added some chopped onions and other seasoning before serving. Served them plain to my 3 dogs who begged for more. Thanks from the bottom of my heart and slow cooker.
These sound great. Will try
Everything looks delicious! Do you have any oven recipes for baby reds?
Thank You!

I do not, but I love this recipe for red potatoes: https://www.themagicalslowcooker.com/slow-cooker-garlic-parmesan-potatoes/
Love this slow cooker mash recipe but can you freeze and reheat any leftovers? Many thanks
Hi! I’ve never had luck freezing potatoes. I apologize.
That looks excellent. I am going to make it for Christmas!
Delicious! I love this! If you need it right away, boil the potatoes with chicken bullion until soft. Drain. Save some of the drained water in case you need to add more liquid after the taters are done. Then add cream cheese and butter to the hot taters and mash with potato masher. No need to add salt or milk. If taters need to be creamier add a tiny bit of saved water ’til it is to your liking. Everybody loves this. For special occasions I add cheddar cheese and bacon bits. Heavenly.
