Jamie Oliver’s Slow Cooker Lamb Shanks features lamb shanks cooked in a slow cooker with a savory, aromatic broth made from red wine, tomatoes, garlic, and fresh herbs. This cooking method ensures the lamb becomes tender and flavorful, making it an ideal dish to serve with mashed potatoes or crusty bread to soak up the delicious sauce.
In a large skillet, heat the olive oil over medium-high heat. Season the lamb shanks with salt and pepper, then add them to the skillet. Brown each shank on all sides for about 4-5 minutes until golden brown. Transfer the browned lamb shanks to the slow cooker.
In the same skillet, add the chopped onion, garlic, carrots, and celery. Sauté for 5-7 minutes until the vegetables are softened and fragrant. Transfer the vegetables to the slow cooker.
Pour the red wine into the skillet and let it simmer for 2-3 minutes, scraping up any browned bits. Add the chopped tomatoes and stir well. Pour this mixture over the lamb shanks and vegetables in the slow cooker.
Add the beef or lamb stock to the slow cooker along with the rosemary sprigs and bay leaf. Season with additional salt and pepper if desired.
Cover the slow cooker and cook on low for 7-8 hours, or until the lamb shanks are tender and easily pull away from the bone.
Once cooked, remove the rosemary sprigs and bay leaf. Serve the lamb shanks with the sauce, garnished with fresh herbs if desired. Pair with mashed potatoes, polenta, or crusty bread to soak up the flavorful sauce.
