Yukon Gold potatoes are perfect for slow cooker buttermilk mashed potatoes because of their medium starch level and buttery flavor. You can use higher-starch russets, but the mashed potatoes may end up being more grainy.

Toss the peeled and cut potatoes into the slow cooker with some water and seasonings, then let ’em cook. It can be a nice option to do most of the prep earlier in the day!

Once the potatoes are tender, drain the water and discard the bay leaf and garlic cloves. Return the potatoes to the warm slow cooker and mash them up. To help keep the buttermilk mashed potatoes creamy, you want to keep them warm and avoid adding any cold ingredients at this point.

The buttermilk and sour cream offer and tangier, richer flavor than your everyday mashed potatoes and the green onions add a bright touch!

I love that you can make these mashed potatoes in advance and even let them sit in the slow cooker for an additional one or two hours before serving. Just loosen them to the desired consistency with more warmed buttermilk or milk.

Buttermilk mashed potatoes are an awesome side dish option for a holiday meal or special occasion!
