Roast Shoulder of Lamb with Tomatoes and Garlic
This traditional roast shoulder of lamb is transformed beautifully in the slow cooker, where the gentle heat allows the meat to become melt-in-the-mouth tender whilst the tomatoes and garlic create a rich, aromatic sauce. The lamb develops deep flavours as it cooks slowly with these Mediterranean-inspired ingredients, making it ideal for Sunday dinners or special occasions. Serve with crusty bread, potatoes, or fresh vegetables to soak up every drop of the delicious sauce
