This chuck roast recipe is perfect for a hearty and flavorful meal. Using a food processor, blend garlic, rosemary, salt, and pepper to create a paste. Rub the paste all over the chuck roast and let it marinate for at least an hour. Then, sear the roast in a hot skillet until browned on all sides. Transfer the roast to a slow cooker and cook on low for 8 hours. The result is a tender and juicy roast with a delicious garlic and rosemary flavor.
