Ingredients you will need

A few simple ingredients make the best slow cooker mashed potatoes you’ll ever have!

Potatoes: Yukon gold potatoes are the best potatoes for this recipe, but you can use russet potatoes if you like. Yukon gold potatoes make mashed potatoes that are creamy, while russets will come out a bit softer. Red potatoes are too waxy to make good mashed potatoes so I don’t recommend using them.

Butter: this is essential in any mashed potato recipe to help the flavor and texture. You can use salted or unsalted butter or even vegan butter.

Chicken broth: adding chicken broth gives these potatoes rich flavor! Feel free to use vegetable broth as a substitute if needed.

Dill: I love adding fresh dill in mashed potatoes because it gives a fresh, earthy, yet slightly sweet flavor.

Garlic: fresh garlic is another important ingredient, making everything so savory. You can even roast it before adding for a sweeter, caramelized flavor.

Sour cream: the secret ingredient for the smoothest, most creamy mashed potatoes. Greek yogurt is a great substitute for sour cream, as is cream cheese.

Milk: whole milk is a must for this recipe. Milk with less fat will make the mashed potatoes less creamy. You can use almond milk or dairy-free milk too if you need to. Heavy cream is another option if you want an even creamier texture.

Chives: chives make a great garnish for mashed potatoes. Green onions are a good option as well.

How to make slow cooker mashed potatoes

1. Prepare the slow cooker. Start the slow cooker on high heat and place the butter and chicken broth at the bottom, allowing it to melt while you peel and cut the potatoes into 1-inch cubes.

2. Cook the potatoes. Add the chopped potatoes to the slow cooker, top with garlic and dill, then cover and cook for 3-4 hours or until the potatoes are soft and you are able to easily mash them with a fork. Cooking time will vary depending on the size of the potatoes.

3. Mash the potatoes. Once the potatoes are soft enough, add sour cream and milk. Mash the potatoes using a handheld electric mixer or potato masher directly in the slow cooker.

4. Serve the potatoes. Add more milk until you get your desired texture. Season with salt and pepper, top with chives and serve.

Can you put uncooked potatoes in the slow cooker?

Yes! The slow cooker will cook the raw potatoes perfectly. Just make sure to peel and chop the potatoes into 1-inch cubes before placing them in the slow cooker and allow them to cook for 3-4 hours on low.

How long can you keep mashed potatoes in the slow cooker?

You can keep mashed potatoes in the slow cooker on the warm setting for up to four hours without a noticeable change in texture and flavor.

If you need to keep them in the slow cooker for longer than four hours, you may notice a change in color and the mashed potatoes may harden. Add more milk to liven them up and make them creamy once again.

How to keep mashed potatoes warm in the slow cooker

The benefit of using a slow cooker is that you can keep food warm while preparing other components of a meal for a while.

Keep the slow cooker on the warm setting as long as you need. Should the mashed potatoes harden, add more milk as stated above.
