Butter a 2-quart shallow baking dish, and set aside.

Stir together lima beans and remaining ingredients in a large bowl; spoon into prepared dish.

Bake, covered, at 375° for 30 minutes. Uncover; stir and bake 30 more minutes or until bubbly and browned. Serve with a slotted spoon, if desired. Beans will thicken as they begin to cool.
