Make Ahead
Stuff potato shells as directed, but do not top with remaining Cheddar. Refrigerate up to 24 hours. Heat oven to 325ºF. Bake potatoes, uncovered, 45 min. Top with remaining Cheddar; bake 5 min. or until melted. Sprinkle with bacon.
Shortcut
Substitute 4 slices ready-to-serve bacon, chopped, for the crumbled cooked bacon.
