This chuck roast recipe is perfect for those who love bold and tangy flavors. Using a food processor, blend together Dijon mustard, horseradish, garlic, salt, and pepper to create a paste. Rub the paste all over the chuck roast and sear it in a hot skillet until browned on all sides. Transfer the roast to a slow cooker and add beef broth, onions, and potatoes. Cook on low for 8 hours. The result is a tender and flavorful roast with a tangy mustard and horseradish kick.
