Let everything cook together for hours for the deepest, most satisfying beef stew you'll try. Don't skip searing the beef — it creates more deeply flavored meat that develops the flavor of the stew even further. The rosemary and sun-dried tomatoes aren't classically used in beef stew, but they brighten up the flavor and add a real punch. We love the depth that red wine brings, but if it's not your thing, feel free to just substitute for additional beef stock. Just be sure to let the stew cool completely before packing it up.
