Ingredients

• Mutton/Lamb Shanks: 4 bone-in shanks (about 1-1.5 lbs each). Look for shanks with a good amount of meat on the bone. Mutton shanks tend to be larger and more intensely flavored than lamb, but both work beautifully.
• Olive Oil: 2 tablespoons, for searing.
• Salt & Black Pepper: To taste, for seasoning the shanks.
• Yellow Onion: 1 large, chopped.
• Carrots: 2 medium, peeled and chopped into 1/2-inch pieces.
• Celery Stalks: 2, chopped into 1/2-inch pieces.
• Garlic: 4-6 cloves, minced.
• Tomato Paste: 2 tablespoons.
• Dry Red Wine: 1 cup (e.g., Merlot, Cabernet Sauvignon, Pinot Noir). This adds incredible depth; choose a wine you'd enjoy drinking. For a non-alcoholic option, use extra beef broth.
• Beef Broth: 3 cups, low sodium.
• Crushed Tomatoes or Tomato Passata: 1 (15-ounce) can, or 1 cup passata. This provides a crucial acidic component to tenderize the meat and build flavor.
• Fresh Rosemary: 2 sprigs.
• Fresh Thyme: 4-5 sprigs.
• Bay Leaves: 2.
• Cornstarch Slurry (optional): 1 tablespoon cornstarch mixed with 2 tablespoons cold water, for thickening the sauce.
• Fresh Parsley: 1/4 cup, chopped, for garnish (optional gremolata: mix with minced garlic and lemon zest).

Directions

1. Prep the Shanks: Pat the mutton or lamb shanks thoroughly dry with paper towels. This is crucial for achieving a good sear! Season generously all over with salt and black pepper. Don't be shy – this is where a lot of your flavor begins.
2. Sear for Flavor (Optional but Recommended): Heat the olive oil in a large Dutch oven or heavy-bottomed skillet over medium-high heat. Once shimmering, add the shanks (you may need to do this in batches to avoid overcrowding). Sear until deeply browned on all sides, about 3-4 minutes per side. This browning step creates a rich, caramelized crust and adds a crucial layer of flavor (the Maillard reaction) that you can't get from just slow cooking. Transfer the seared shanks to your slow cooker.
3. Build the Braising Base: In the same pot (don't clean it, those browned bits are flavor!), add the chopped onion, carrots, and celery. Sauté over medium heat for 5-7 minutes until softened, scraping up any browned bits from the bottom of the pan. Add the minced garlic and tomato paste, and cook for another minute until fragrant.
4. Deglaze & Add Liquids: Pour in the red wine, scraping the bottom of the pot with a wooden spoon to release all those flavorful fond bits. Let it simmer for 2-3 minutes to reduce slightly. Stir in the beef broth and crushed tomatoes (or passata). Bring the mixture to a gentle simmer.
5. Slow Cook to Perfection: Pour the vegetable and liquid mixture over the shanks in the slow cooker. Add the fresh rosemary, thyme, and bay leaves, ensuring the shanks are mostly submerged in the liquid. Place the lid on your slow cooker.
   1. Cook on LOW: 6-8 hours, or until the shanks are incredibly tender and practically falling off the bone.
   2. Cook on HIGH: 3-4 hours, or until the shanks are fork-tender.
   3. Lid Tips: Resist the urge to lift the lid during cooking, as this releases heat and moisture, extending the cooking time.
6. Finish & Thicken Sauce (Optional): Carefully remove the cooked shanks from the slow cooker and set them aside on a plate, covered loosely with foil. Skim any excess fat from the surface of the braising liquid. If you prefer a thicker sauce, you can do one of two things:
   1. Reduce: Transfer the liquid to a saucepan and simmer over medium-high heat until it reduces and thickens to your desired consistency.
   2. Slurry: Whisk in the cornstarch slurry and simmer for 1-2 minutes until thickened.
7. Rest & Serve: Return the shanks to the thickened sauce. Let them rest for 10-15 minutes before serving. This allows the juices to redistribute, ensuring maximum tenderness. Plate the shanks with plenty of the rich sauce, and garnish with fresh chopped parsley or a gremolata for a bright finish.
