Braise. Add in beef broth, Worcestershire sauce, Dijon mustard, and balsamic vinegar. Stir to combine, then add back the roast, the bay leaves, and an herb bundle made with thyme and rosemary. Cover and place in the oven at 300°F, undisturbed, for 3 - 3 ½ hours. Make sure there is enough liquid to cover the roast at least halfway up the sides, but don't submerge it!
