Preheat oven to 300 degrees.

Whisk together your beef broth, soy sauce, garlic chili sauce, gochujang, sesame oil, rice wine vinegar and light brown sugar in a large measuring cup or bowl until well combined. Set aside.

Pat your roast dry and then season with salt and pepper. In a large Dutch oven, heat the oil over medium-high heat. Brown the meat on all sides. Remove the meat from the pan to a plate. Set aside. Add your onions and cook for 3-5 minutes before adding your ginger and garlic and continue to cook for 1 minute.

Pour in your sauce and cook for about 4-5 minutes before adding your roast back to the Dutch oven. Cover the Dutch oven and cook for roughly 2 ½ hours or until the meat is super tender and shreds easily.

Before shredding the meat, whisk two tablespoons of cornstarch with a ¼ cup of water and stir it into the sauce to thicken it.

Serve with steamed white rice or mashed potatoes, topped with sesame seeds if desired.
