Ingredients You’ll Need

3 pounds yukon gold or red potatoes: These types yield creamy, delicious mashed potatoes. You can substitute with russet potatoes if needed.
1 cup chicken broth or veggie broth: This adds flavor and moisture. Low-sodium broth is a great option for less sodium.
1/3 cup unsalted butter, cut into small pieces: For that rich, creamy texture. You can use salted butter but adjust the added salt accordingly.
4 cloves garlic, minced or 1 teaspoon garlic powder: For a wonderful aromatic flavor. Garlic powder is a great alternative if you’re short on fresh garlic.
1 teaspoon onion powder: Enhances the savory flavor profile.
1/2 cup sour cream or plain Greek yogurt: Adds creaminess and a slight tang. Greek yogurt is a healthier option.
1/2 teaspoon salt: Season to taste.
1/4 teaspoon black pepper: For a subtle kick.
1/3 cup cream, warmed: Use more if needed to achieve your desired consistency. You can substitute with milk or a dairy-free alternative if preferred.
Chopped green onions: Optional garnishing for a fresh touch.

How to Make Slow Cooker Mashed Potatoes

Prepare the Slow Cooker: Start by adding the peeled and chopped 3 pounds of yukon gold or red potatoes into the slow cooker, then pour in 1 cup of chicken broth or veggie broth. This ensures the potatoes cook evenly and absorb flavor.
Add Flavor: Top with 1/3 cup of unsalted butter cut into small pieces. Sprinkle in 1 teaspoon of onion powder and add the 4 cloves of minced garlic to infuse those delicious flavors as they cook.
Cook Low and Slow: Cover and cook on high for 3-4 hours, or until the potatoes are tender enough that a fork easily pierces through them. You’ll know they’re done when the edges begin to bubble a bit and the scent of garlic fills your kitchen.
Mash it Up: Using a potato masher or an electric mixer, smash the potatoes to your desired texture. I recommend leaving some chunks for a rustic feel.
Cream it Up: Stir in 1/2 cup of sour cream or plain Greek yogurt, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Taste and adjust the seasonings as needed. Gradually mix in the warmed 1/3 cup of cream until your mashed potatoes reach the perfect creaminess.
Serve and Garnish: Transfer your slow cooker mashed potatoes to a serving dish, and top with chopped green onions and an additional pat of butter if you’d like. Enjoy them warm!

Storing & Reheating

To store leftover mashed potatoes, let them cool slightly before transferring them to an airtight container. Keep in the refrigerator for up to 3 days. For longer storage, you can freeze portions in freezer-safe containers for up to 3 months. When reheating, warm them in the microwave or on the stovetop, adding a splash of cream or milk to refresh their creamy texture. Just be mindful that freezing may alter their texture slightly.

Chef’s Helpful Tips

Don’t Over-Mash: To prevent gluey potatoes, mash gently and avoid overworking them.
Room Temperature Ingredients: Let your cream and sour cream sit out for a bit before mixing; it helps create a smoother mash.
Timing is Key: If you’re short on time, the high setting is perfect, but if you can spare it, the low setting on your slow cooker will yield even better results.
Flavor Enhancements: Consider adding grated cheese or herbs like rosemary for more depth of flavor.
Make-Ahead Option: Feel free to make these mashed potatoes a day ahead, then reheat gently before serving.
