Blend the peeled Asian pear with soy sauce until smooth and set aside.
Cut the chuck roast into large cubes.
Heat oil in a Dutch oven or oven-safe pot, and sear the beef on all sides until browned. Then, remove it and set it aside.
In the same pot, sauté garlic and onion until soft and fragrant. Pour in the pear-soy mixture, then add dark soy sauce, honey, gochujang, sesame oil, beef broth, and rice vinegar.
Return the beef to the pot.
Cover and bake at 325F for 3-4 hours or until beef is tender. Add carrots during the last hour of cooking. Serve over rice and spoon the rich sauce on top.
