These classic stuffed potatoes are a comforting side dish that pairs well with almost any main course. Russet potatoes are baked until tender, then hollowed out to create a sturdy shell. The fluffy potato centers are mashed with rich butter, milk, and sharp Cheddar cheese before being spooned back into the skins. Fresh chives add a bright, oniony bite to the creamy filling. They make an excellent addition to a holiday spread or a hearty weeknight steak dinner.
