For the Red Wine Gravy

- 3 tablespoons cornstarch or 6 tablespoons all-purpose flour
- 2 cups beef stock or broth

Prepare and Slow Cook the Lamb Shanks
Prepare the lamb: Trim any excess fat from the lamb shanks, if needed, and pat them dry with paper towels.
Sear in batches: Heat 1 tablespoon of olive oil in a heavy-bottomed pan over medium-high heat. Sear two lamb shanks until browned on all sides. Repeat with the remaining shanks and olive oil, leaving enough space between the pieces for even browning.
Transfer to the slow cooker: Place the seared lamb shanks in a 6-quart slow cooker. Add the onions, carrots, and garlic. Season with ½ teaspoon coarse salt and ¼ teaspoon ground black pepper. Toss gently to combine and set aside.
Simmer the red wine: Pour the red wine into the same pan used to sear the lamb. Simmer over medium-low heat for 4–5 minutes, scraping up the browned bits from the pan. Allow the wine to reduce slightly.
Add the braising liquid: Pour the red wine mixture into the slow cooker. Add the beef stock, tomato sauce, tomato paste, crushed beef bouillon cubes, rosemary, and bay leaves. Stir gently to combine.
Cook until tender: Cover and cook on HIGH for 6 hours or LOW for 8–10 hours, until the lamb becomes fall-apart tender.
Make the Red Wine Gravy and Serve
Remove the cooked lamb: Carefully transfer the lamb shanks to a platter and cover to keep warm. Skim excess fat from the braising liquid with a slotted spoon if needed.
Prepare the cornstarch slurry: Transfer the braising liquid to the same pan used to sear the lamb and bring it to a gentle simmer over medium-low heat. In a small bowl, whisk all 3 tablespoons of cornstarch with 3 tablespoons of cold water until smooth.
Simmer until thickened: Gradually whisk the cornstarch slurry into the simmering gravy, adding only as much as needed. Simmer for 4–5 minutes, stirring, until the gravy reaches your preferred consistency.
Garnish and serve: Sprinkle the lamb shanks with chopped parsley. Spoon the gravy over the meat and serve with mashed potatoes or mashed cauliflower and steamed peas.
- Use 6 tablespoons of all-purpose flour instead of 3 tablespoons of cornstarch. Mix the flour with cold water before adding it to the simmering gravy, then cook until thickened and the raw flour taste is gone.
- Cook the lamb shanks on HIGH for 6 hours or LOW for 8–10 hours, adding more time if needed until fork-tender.
- If the gravy becomes too thick, stir in a little beef stock until it reaches your preferred consistency.
Storage and Reheating
Refrigerate: Transfer leftover lamb and gravy to shallow, airtight containers and refrigerate within 2 hours. Keep refrigerated for up to 3–4 days.
Freeze: Place cooled lamb and gravy in freezer-safe containers and freeze for up to 3 months for best quality.
Reheat: Warm the lamb with its gravy in a covered saucepan over low heat until thoroughly heated to 165°F (74°C). Add a splash of beef stock if the sauce is too thick.
