Slow Cooker Mashed Potatoes

Want to make mashed potatoes ahead and have them turn out yummy? Try this:
5 pounds red potatoes, peeled and cut into chunks
1 tablespoon minced garlic
3 cubes chicken bouillon
1 8oz container sour cream
1 8oz package cream cheese, softened
1/2 cup butter
salt and pepper to taste

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. 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.
