Although not the most popular of meats in American cuisine, lamb has long been a favorite in dishes around the world, especially in Mediterranean cuisine. Easy to prepare and flavorful, lamb gives a sweeter, earthier taste to recipes that call for beef. Lamb shanks are cut from the leg of the animal, containing a central bone surrounded by hearty meat. They are more inexpensive than other cuts of lamb.

While some cuts of lamb are delicious cooked briefly at high heat (like grilling), lamb shanks are a different matter. Braising is a better option since the meat tends to be a little tougher, and low and slow cooking renders it fork-tender. This slow-roasted lamb shank recipe is such a great and easy way to enjoy lamb. It only requires a few ingredients, and even though it takes some time, it's almost all hands-off.

You'll need to plan a few hours to prepare ahead for this recipe to allow the lamb to slow-roast, but it will be time well-spent. Serve with mashed potatoes or grain to soak up the juices.


  • 4 lamb shanks
  • 2 tablespoons olive oil
  • Salt (to taste)
  • Fresh ground black pepper (to taste)
  • 6 cloves garlic (unpeeled, the skin pierced with the tip of a knife)
  • 6 sprigs fresh rosemary
  • 1 cup chicken broth

Steps to Make It

  1. Gather the ingredients. Preheat the oven to 450 F.

  2. Place the shanks in a roasting pan just large enough to fit them in one layer and rub with the olive oil. Season generously with salt and pepper, or to taste.

  3. Roast for 20 minutes to get a nice brown color. Remove from the oven and turn the temperature down to 325 F.

  4. While waiting for the oven to cool down, spoon out any excess fat and scatter the garlic cloves and rosemary over and around the lamb.

  5. Wrap the braising or roasting pan very tightly with several layers of heavy-duty aluminum foil (remember: you want as tight a seal as possible), and return to the oven. Roast the lamb for an additional 2 hours. Resist the temptation to open the foil and check on it until the 2 hours are up because you'll increase the risk of the meat becoming too tough.

  6. Remove the foil, pour in the chicken broth, and turn the heat up to 400 F. Roast for 15 minutes, and remove. The lamb shanks are done cooking when they are nicely browned and fork-tender.

How Much Meat Does the Average Lamb Shank Yield?

An average 1-pound lamb shank will yield about 7 1/2 to 8 ounces of meat (uncooked). One lamb shank will serve from 1 to 2 people, depending on the size of the shank and appetite.

How Tender Is the Meat on a Lamb Shank?

Lamb shank meat has a good deal of connective tissue, making it a tough meat. Long, slow roasting or braising breaks the tissue down, making the meat melt-in-your mouth tender.


  • For a neater, more attractive look, sever the tendon near the top of the narrow end of the lamb shank or French the shank by cutting away the top 1/2-inch of meat and tendon.
  • If you are roasting the lamb shanks in a braising dish or Dutch oven with a lid, you can use that instead of aluminum foil. Just make sure the lid is tight-fitting to prevent the meat from becoming dried out.
  • While achieving a certain internal temperature is often a concern when cooking meat, you don't need a thermometer for this recipe. Lamb shanks are cooked for a long period of time and will register well above the minimum safe temperature.
  • If your lamb shanks are not fork-tender after following this recipe, you can put them back in the oven. Shanks tend to get more tender the longer you cook them, but they will begin to dry out and overcook if you roast them for too long.
  • The soft garlic cloves can be squeezed out of their skins and spread on the lamb. This will add a wonderful, more intense flavor.

Recipe Variation

  • If you don't have fresh rosemary, use sprigs of fresh thyme.
