These no boil slow cooker mashed potatoes are the easiest mashed potatoes you’ll ever make! They’re rich, creamy and the perfect side dish for the holidays or big family meals.
If you’re looking for an easy, hands-off side dish to make for Thanksgiving this year, this slow cooker mashed potatoes recipe is it! This is a real deal mashed potatoes recipe with butter, sour cream and milk, but if you’re looking for something lighter you’ll have to try my healthy mashed potatoes recipe.
The thing I love most about this recipe is that there’s no need to boil or drain the potatoes. Just pop everything in your slow cooker, let it work its magic and a few hours later you’ll have perfectly soft potatoes ready to be mashed into creamy, smooth mashed potatoes!
Using a slow cooker not only saves stovetop space, but it also keeps these potatoes warm until you’re ready to serve, which is such a game-changer especially when making a bunch of different recipes for the holidays. No matter how hard I try to get everything done at the same time, it never seems to happen, so having a way to keep at least one side dish warm while everything else finishes cooking is huge!
Why You’ll Love This Recipe
- Hands-off – With the slow cooker doing all the work, you can prep these potatoes and go about your day. No boiling, straining or draining required. Perfect for busy holiday prep!
- Super creamy – The mix of butter, sour cream (or Greek yogurt) and milk makes these mashed potatoes extra rich and creamy.
- Serves a crowd – This recipe makes a big batch, which is perfect for feeding a crowd at Thanksgiving dinner.

Ingredients Needed
- gold potatoes – yukon gold potatoes are my preferred potatoes for mashed potatoes because they’re so creamy and buttery! Look for small-medium sized potatoes with smooth skin and free from any bruises or cuts. If you don’t have Yukon gold potatoes on hand, russet potatoes will also work. I just suggest avoiding red or white potatoes as they are waxier and may require more mashing, which can lead to a different texture.
- butter – can’t have real deal mashed potatoes without the butter! You can use salted or unsalted butter. If you use salted, you might want to cut back on the amount of salt used.
- sour cream or greek yogurt – helps to achieve that perfectly silky smooth texture. Both sour cream and greek yogurt are great options.
- milk – helps make the mashed potatoes extra creamy. Whole milk is my go-to for this recipe, but any milk you like will work. Unsweetened almond milk is a great option if you want to reduce the fat and calories.
- seasonings – you’ll need garlic powder, onion powder, salt and black pepper.

Variations
- Make it dairy-free: Use vegan butter, vegan sour cream or yogurt and a non-dairy milk option. The flavor won’t be the same, but I’m sure it’ll still be delicious!
- Low-carb: If you’re looking to lighten things up, check out my healthy mashed cauliflower recipe. It’s just as creamy and comforting, but with fewer carbs.
- Use sweet potatoes: Looking for a sweet potato option? Try my mashed sweet potatoes instead.
- Add more garlic: If you’re a garlic lover, add some fresh minced garlic to the slow cooker with the potatoes for an extra boost of flavor. Roasted garlic also works beautifully here for a sweet, mellow garlic taste.
- Cheesy: Stir in a handful of shredded cheddar or Parmesan cheese after mashing for an irresistibly cheesy version. You could also sprinkle some cheese on top and let it melt before serving!

Brittany’s Tips!
For easy cleanup, you can mash the potatoes directly in the slow cooker. Just switch to the “keep warm” setting afterward so they stay hot and ready until you’re ready to serve.
How to Serve
I love serving these mashed potatoes as a side for Thanksgiving, but there are so many great pairing options. Here are some delicious ideas:
Storing Leftovers
Transfer any leftover mashed potatoes to an airtight container and store them in the fridge for up to 3-4 days.
When you’re ready to reheat, warm them gently on the stovetop or in the microwave, adding a splash of milk to bring back that creamy texture.
Frequently Asked Questions
Not necessarily! If you love a rustic mash, leave the skins on for extra fiber and nutrients. But if you’re aiming for super smooth and creamy, peeling is the way to go. It’s totally up to you!
Easy fix! Swap in plant-based butter, dairy-free yogurt, and your favorite unsweetened almond, oat, or cashew milk. You’ll still get that creamy, dreamy texture without the dairy.
Just add a splash of milk or an extra pat of butter when you reheat them on the stovetop or in the microwave. This keeps them soft and creamy, like they’re fresh from the slow cooker.
