Slow Cooker Korean Beef (Sweet & Sticky Gochujang Sauce) is so good, people go crazy for it (no exaggeration!). It is a true set-it-and-forget-it dinner - just simmer an economical chuck roast until it is full apart tender, toss in a sweet, sticky, and slightly spicy gochujang sauce. Serve it over rice, see the sauce sink in, and watch it disappear!
