This chuck roast recipe is perfect for a special occasion or a fancy dinner party. Using a food processor, blend together garlic, thyme, 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 red wine, beef broth, and diced tomatoes. Cook on low for 8 hours. The result is a tender and flavorful roast with a rich red wine sauce.
