Notes
Storage
You can store them right in the slow cooker insert with the lid on, or in an airtight container. Refrigerate them for 3-5 days. You can also freeze up to 3 months as well! To reheat: You can reheat slow cooker mashed potatoes in either the microwave or on the stovetop. You may want to add some additional buttermilk or cream to get back the creamy texture.Nutrition
Recipe Tips
- Add whole garlic cloves to the cut potatoes as they cook. Mash potatoes and garlic together for garlic mashed potatoes.
- Store buttermilk mashed potatoes within two hours of cooking them to avoid any bacteria growth.
- Don’t add your liquid all at once – Your potatoes won’t be able to soak up all the liquid in one go and if you try to force them to you will end up with wet mashed potatoes. Add your liquid in small increments and thank me later.

Recipe Help
Yep just know that the tang from the buttermilk won’t be there. If you don’t have any, make your own by adding 1 tablespoon of vinegar or lemon juice to a measuring cup and add 1 cup of milk. Let it sit for 10 minutes to make a swap. Or use plain greek yogurt or sour cream that has been thinned out with milk as a swap.
Russet works fine too. They will end up lighter and fluffier.

I made these creamy slow cooker mashed potatoes for our holiday meal, and they were a huge hit! The buttermilk added a tangy richness to the potatoes, making them incredibly flavorful and velvety smooth. The best part was being able to prep them ahead of time in the slow cooker, which made my life so much easier on the big day
