Melt butter in a large Dutch oven over medium-high heat. Stir in potatoes and next 5 ingredients, and bring to a boil. Reduce heat to medium-low, and cook, stirring gently, 15 minutes or until potatoes are tender.
Spoon mixture into a lightly greased 13- x 9-inch baking dish; sprinkle with cheese.
Bake at 400 for 25 to 30 minutes or until bubbly and golden brown.
Remove to a wire rack, and let stand 10 minutes before serving.
