These Slow Cooker Creamy Mashed Potatoes are so simple to make and have the best flavor. If you need a Thanksgiving side dish, this is one we highly recommend.
In a large pot of lightly salted boiling water, cook the potatoes, garlic and bouillon until potatoes are tender but firm (about 15 minutes). Drain, reserving water for later.
In a bowl, mash potatoes with sour cream and cream cheese, adding reserved water as needed to attain desired consistency.
Transfer the potato mixture to a slow cooker, cover, and cook on Low for 2 to 3 hours.
Just before serving, stir in butter and season with salt and pepper to taste. Sprinkle with parsley flakes if desired.
Notes
If you want smooth mashed potatoes, I would choose either the hand mixer or stand mixer since they can eliminate most of the lumps.
