What’s In This Slow Cooker Mashed Potatoes

When it comes to Slow Cooker Mashed Potatoes, the ingredients are simple but powerful. Each component contributes to the dreaminess of the final dish. The right potatoes, combined with creamy milk and rich butter, create a delightful texture and flavor.
- 5 pounds russet potatoes – The star of the dish. High-starch potatoes like russets yield the fluffiest mash.
- 1 1/2 cups milk – Adds creaminess and helps achieve that perfect consistency.
- Salt and freshly ground black pepper – Essential for seasoning and enhancing the flavors of the potatoes.
- 1 cup butter (2 sticks) – Rich, creamy goodness that makes the mash indulgently delicious.
- 1/2 cup sour cream – Adds a tangy flavor that balances the richness of the butter.
- Fresh chives – Optional, but they provide a fresh taste and a pop of color when garnished.
How to Prepare Slow Cooker Mashed Potatoes

Making Slow Cooker Mashed Potatoes is as easy as can be! Just a few simple steps will lead you to creamy perfection. Let’s dive into the process.
- Start by peeling and cutting the russet potatoes into 1-inch pieces. It’s important to ensure uniform size for even cooking. Place them in the bottom of your slow cooker.
- Next, pour in milk over the potatoes. This will help them soften and become creamy as they cook.
- Generously sprinkle with salt. I recommend using about 1 tablespoon to start, but feel free to adjust based on your taste.
- Now, add both sticks of butter on top of the potatoes. This will melt and infuse the potatoes with rich flavor.
- Cover the slow cooker and set it to cook on HIGH for 3 to 4 hours. Make sure to give it a gentle stir every hour to ensure even cooking.
- Once the cooking time is up, carefully remove the lid. The potatoes should be tender and easily pierced with a fork.
- Using a potato masher, mash the potatoes directly in the slow cooker. They might appear a little oily at first, but keep mashing until it’s a uniform consistency.
- Fold in the sour cream and mix well. This will add a creamy texture and a delightful tang to the mash.
- Finally, season with more salt and freshly ground black pepper to taste. I suggest starting with 2 teaspoons of salt and 1 teaspoon of pepper.

Slow Cooker Mashed Potatoes
Ingredients
Equipment
Method
- In the bottom of a slow cooker, add potatoes and milk. Sprinkle with salt, then top with butter. Cover and cook on HIGH for 3 to 4 hours, stirring once every hour.
- Remove cover and mash potatoes to a uniform consistency (they will look oily until the butter has been thoroughly mashed into the potatoes; don't worry, just keep mashing). Fold in the sour cream and season to taste with salt and pepper (I like 2 teaspoons salt and 1 teaspoon pepper).
Notes
- Potatoes: For the fluffiest, smoothest, and most flavorful mashed potatoes, choose high-starch potatoes like russet, Idaho, or Yukon gold potatoes. Waxy potatoes (such as new, red, or white varieties) require more mashing to become creamy which could result in gluey, pasty spuds.
- Chives: The fresh chives are totally optional here but they go really well with the sour cream. If chives feel weird on your Thanksgiving table, though, just leave them out.
- Yield: This recipe makes about 12 cups mashed potatoes, enough for 12 (1-cup) servings.
- Storage: Store leftovers covered in the refrigerator for up to 4 days.
