Preheat oven to 375 degrees. Melt butter in a large skillet over medium heat; add sliced onions. Cook, stirring often, about 30-45 minutes or until onions are caramel-colored.
Combine onions with remaining ingredients, except sweet potato chips, and spoon into a lightly greased 1 ½ to 2-cup round baking dish. Bake uncovered for 30 minutes or until dip is golden and bubbly. Serve with sweet potato chips. Yields about 4 cups (enough for a group of six to ten depending on whether or not you are serving other hors’ d’oeuvres).
Make ahead: Prepare dip a day ahead but do not bake. Cover and refrigerate overnight. Bake uncovered.
