Slow-Braised Lamb Shank with Creamy Polenta and Rosemary Jus

This slow-braised lamb shank recipe delivers restaurant-level elegance right in your own kitchen. The meat is cooked low and slow until it practically melts off the bone, then served over a bed of creamy Parmesan polenta and finished with a glossy, deeply flavored rosemary jus.

It's a showstopper for Sunday dinners or special occasions, yet surprisingly simple to put together. The rich, savory sauce and tender lamb will have everyone asking for seconds.

This recipe takes humble lamb shanks and transforms them into a luxurious meal through the magic of low-and-slow braising. The shanks are first seared to develop a deep, caramelized crust, then simmered in a fragrant mixture of red wine, beef broth, and fresh rosemary until they become fall-apart tender.

The accompanying polenta is cooked with milk and finished with butter and Parmesan, creating a velvety base that soaks up every drop of the glossy jus. It's a dish that feels both rustic and refined, perfect for impressing guests or treating yourself to something special.

Ingredients

Why this recipe works

The braising method is the key to this recipe's success. Cooking the lamb shanks at a low temperature in a covered pot with liquid allows the tough connective tissue to break down slowly, turning the meat buttery and tender.

The long, gentle simmer also melds the flavors of the wine, broth, and aromatics into a rich, complex sauce that clings to the meat.

The polenta provides the perfect contrast to the bold lamb. Cooked with milk and enriched with butter and Parmesan, it becomes creamy and luxurious, with a subtle sweetness that balances the savory jus. The combination of tender meat, velvety polenta, and glossy sauce creates a harmonious, satisfying bite that's pure comfort.

Notes and substitutions

Choose lamb shanks that are meaty and have a good amount of marbling; this ensures they stay moist during the long braise. If you can't find lamb shanks, beef short ribs or beef shanks are excellent substitutes. The red wine should be something you'd drink—a dry red like Cabernet Sauvignon or Merlot works well.

A Dutch oven is ideal for this recipe because it distributes heat evenly and retains it well, but any heavy-bottomed pot with a tight-fitting lid will work.

The polenta requires regular stirring to prevent lumps and sticking, so plan to stay close to the stove during the last part of cooking. For a smoother texture, you can also use instant polenta, but the cooking time will be shorter.

• lamb shanks: Beef short ribs or beef shanks can be used; adjust cooking time as needed until fork-tender.
• red wine: Use extra beef broth plus 1 tablespoon red wine vinegar for a non-alcoholic version.
• polenta cornmeal: Coarse cornmeal works; use the same amount and cook until creamy.
• Parmesan cheese: Pecorino Romano adds a sharper flavor; use the same amount.
