This is another recipe from Best Loved Slow Cooker Recipes (Page 148). They were great - served with BBQ Chicken.
1 can cream of chicken soup
1 container (8 oz) sour cream
1/4 cup chopped onion
1/4 cup plus 3 tablespoons melted butter, divided
1 teaspoon salt
2 pounds red potatoes, peeled & chopped
2 cups shredded cheddar cheese
1 1/2 - 2 cups stuffing mix
Combine soup, sour cream, onion, 1/4 cup butter, and salt in small bowl.
Combine potatoes and cheese in Crock Pot. Pour soup mixture over potato mixture. Mix well. Sprinkle stuffing mix over potato mixture; drizzle with remaining 3 tablespoons butter. Cover; cook on LOW 8-10 hours or HIGH 5-6 hours, or until potatoes are tender.
*** I cooked on LOW for 8 hours and the edges around the crock pot were pretty crispy. I wouldn't plan on cooking longer than 8 hours.
