Three Ways to Cook Icelandic Lamb
A box of Icelandic lamb can become three very different meals: a slow, comforting braise; an elegant roasted rack; or a hearty shepherd’s pie made for feeding a family. The right recipe depends less on cooking experience than on the cut in front of you and the kind of meal you want to serve.
These three recipes highlight the versatility of Icelandic lamb while keeping the ingredients familiar and the instructions easy for everyone. Start with the quick guide below, then move to the recipe that fits your cut.

Slow-Cooked Icelandic Lamb With Red Wine Gravy
A slow braise is one of the most delicious ways to prepare lamb. Gentle heat gives a bone-in leg, shoulder roast, or shanks time to become tender while the wine, broth, herbs, and vegetables build a rich sauce around the meat.
This recipe is especially good for a relaxed Sunday dinner or a colder evening when you want the oven to do most of the work. It also uses the braising liquid twice: first to cook the lamb, then as the base of a savory red wine gravy for your meat, and over mashed potatoes.
Recipe at a Glance
Serves: 6–8
Preparation time: 25 minutes
Cooking time: 3–5 hours
Oven temperature: 300°F
Best cookware: Large Dutch oven or covered roasting pan
Choose Your Cut
Use one of the following:
One 3-4 pound bone-in leg of lamb
One 2-3 pound bone-in lamb shoulder roast
Three to four lamb shanks, approximately 2-4 pounds total
Cook Time: Bone-in leg of lamb: about 45–60 minutes per pound, Shoulder roast: about 60–75 minutes per pound, Lamb shanks: generally 2½–3½ hours total, regardless of combined weight
Shanks generally become tender first, followed by the shoulder. A larger leg may need the full cooking time. Let tenderness, not the clock, tell you when the lamb is ready. when the fork slides in and shreds the meat, you'll know.
Ingredients
For the Lamb
1 leg of lamb, shoulder roast, or package of lamb shanks
2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
2 tablespoons beef tallow, butter, or olive oil
1 large yellow onion, roughly chopped
3 carrots, cut into large pieces
5 garlic cloves, lightly crushed
2 tablespoons tomato paste
2 cups dry red wine
2–3 cups beef or lamb broth
2 sprigs fresh rosemary
4 sprigs fresh thyme
2 bay leaves
For the Gravy
Ingredients
2 cups strained braising liquid
2 tablespoons cornstarch
2 tablespoons cold water
1 tablespoon butter or beef tallow
Salt and pepper to taste
Brown the Lamb
Preheat the oven to 300°F. Pat the lamb dry and season it generously with salt and pepper.
Heat the tallow, butter, or olive oil in a large Dutch oven over medium-high heat on stovetop. Brown the seasoned lamb deeply on every side, working in batches if you are using shanks. This takes about 8–12 minutes and builds the foundation of the sauce. Transfer the lamb to a plate.
Build the Braising Broth
Reduce the heat to medium. Add the onion, carrots, and celery to the same pot and cook for 6–8 minutes, stirring occasionally. Add the garlic and tomato paste and cook for another minute.
Pour in the red wine and scrape the bottom of the pot to loosen the browned bits. Simmer for about five minutes, allowing the wine to reduce slightly.
Return the lamb to the pot. Add enough broth to bring the liquid roughly halfway up the sides of the meat, then add the rosemary, thyme, and bay leaves.
Slow Cook Until Tender
Cover the pot tightly and transfer it to the oven. Begin checking shanks after 2½ hours and larger roasts after 3½ hours. Turn a large roast once during cooking if the liquid does not cover it evenly.
The lamb is ready when a fork slides into the meat easily and the meat begins pulling away from the bone. Depending on the cut and its size, allow approximately:
Lamb shanks: 2½–3½ hours
Shoulder roast: 3½–4½ hours
Leg of lamb: 3½–5 hours
Transfer the finished lamb to a platter, tent it loosely with foil, and let it rest while you make the gravy.
Turn the Broth Into Red Wine Gravy
Strain the braising liquid and skim away any excess fat. If needed, simmer it uncovered until reduced to about 2 cups.
In a small bowl, whisk the cornstarch and cold water together until completely smooth. Bring the braising liquid to a gentle simmer, then slowly whisk in the cornstarch slurry. Simmer for 1–2 minutes, stirring constantly, until the gravy thickens enough to coat the back of a spoon.
Remove from the heat and stir in the butter or tallow for a richer finish. Taste and season with salt and pepper before serving.
Serve the Slow-Cooked Lamb
Serve the lamb whole for a centerpiece meal or pull it into large pieces and spoon the gravy over the top. Mashed potatoes, roasted root vegetables, polenta, or crusty bread all work well with the rich broth.
If you prefer not to cook with wine, replace it with an equal amount of broth and add one tablespoon of balsamic or red wine vinegar for acidity.
Garlic and Herb-Crusted Rack of Icelandic Lamb
A rack of lamb looks impressive on the table, but it is one of the simplest cuts to prepare. A quick sear creates a browned exterior, while garlic, mustard, lemon, and fresh herbs form a flavorful crust in the oven.
This is the recipe to choose when you want a special-occasion meal without spending the entire day in the kitchen. Icelandic lamb is naturally mild and tender, so the straightforward seasoning complements the meat instead of covering it.
Recipe at a Glance
Serves: 2–4
Preparation time: 15 minutes
Cooking time: 20–30 minutes
Oven temperature: 425°F
Resting time: 10 minutes
Ingredients
1 rack of lamb, approximately 1½–2 pounds
1½ teaspoons kosher salt
½ teaspoon freshly ground black pepper
1 tablespoon beef tallow, butter, or olive oil
2 tablespoons Dijon mustard
3 garlic cloves, finely minced
1 tablespoon finely chopped fresh rosemary
1 tablespoon finely chopped fresh parsley
1 teaspoon fresh thyme leaves
½ cup plain breadcrumbs, optional
Zest of 1 lemon
1 tablespoon melted butter or olive oil
Prepare the Rack
Preheat the oven to 425°F. Pat the rack dry. If there is a thick layer of fat on top, lightly score it in a crosshatch pattern without cutting into the meat. Season the entire rack with salt and pepper.
Mix the mustard, garlic, rosemary, parsley, thyme, lemon zest, and melted butter or olive oil in a small bowl. For a crispier crust, stir in the breadcrumbs.
Sear and Roast
Heat the tallow, butter, or olive oil in a large oven-safe skillet (we prefer cast iron) over medium-high heat. Place the rack fat-side down and sear for 3–4 minutes, until deeply browned. Briefly sear the other side for 1–2 minutes.
Remove the skillet from the heat. Brush the herb mixture over the fat side and ends of the rack, pressing it gently onto the surface.
Place the skillet in the oven with the rack fat-side up. Roast for approximately 18–25 minutes, or until desired internal temp. Check the temperature in the thickest portion without touching the bone.
Rest and Serve the Rack
Transfer the rack to a cutting board and let it rest for 10 minutes before slicing between the bones.
Arrange the chops on a warm platter and spoon any juices from the cutting board over the top. A squeeze of fresh lemon just before serving brightens the herbs.
Serve with roasted or mashed potatoes, a simple green salad, glazed carrots, or seasonal vegetables. For a larger gathering, roast two racks side by side and be sure to use the internal temperature, not the clock, as your final guide.
Ground Icelandic Lamb Shepherd’s Pie
Shepherd’s pie was made for cold evenings, large gathering, and the kind of cooking that turns simple ingredients into a complete meal. Ground lamb, vegetables, and savory gravy are tucked beneath a golden layer of mashed potatoes.
This recipe is a good choice when you want something filling, familiar, and easy to prepare ahead of time. The mild richness of Icelandic lamb gives the filling depth without overpowering the vegetables, herbs, or potatoes.
Recipe at a glance
Serves: 6 to 8
Preparation time: 30 minutes
Cooking time: 35 minutes
Oven temperature: 400°F
Best dish: A 9 by 13 inch baking dish or deep 12 inch oven-safe skillet
Ingredients
For the mashed potato topping
2½ pounds Yukon Gold or russet potatoes, peeled and cut into chunks
4 tablespoons butter
½ to ¾ cup warm milk or cream
1 teaspoon kosher salt, plus more for the cooking water
Black pepper to taste
1 egg yolk, optional
For the lamb filling
1½ pounds ground lamb
1 tablespoon beef tallow, butter, or olive oil, if needed
1 medium yellow onion, diced
2 carrots, diced
2 celery stalks, diced
3 garlic cloves, minced
2 tablespoons tomato paste
2 tablespoons all-purpose flour
1 cup dry red wine
1 cup beef or lamb broth
1 tablespoon Worcestershire sauce
1 teaspoon fresh rosemary, finely chopped
1 teaspoon fresh thyme leaves
1 teaspoon salt, or to taste
½ teaspoon freshly ground black pepper
Make the mashed potatoes
Place the potatoes in a large pot and cover them with cold, salted water. Bring to a boil, then reduce the heat and simmer for 15 to 20 minutes, until tender.
Drain well and return the potatoes to the warm pot. Mash with the butter, then add enough warm milk or cream to make them smooth and spreadable. Season with salt and pepper. Stir in the egg yolk, if using, once the potatoes have cooled slightly.
Cook the lamb filling
Preheat the oven to 400°F.
Heat a large skillet over medium-high heat. Add the ground lamb and cook, breaking it into small pieces, until browned, season with a salt, pepper, garlic based seasoning. Add a little tallow, butter, or olive oil if the lamb is very lean. If the pan contains more rendered fat than needed, carefully spoon off the excess.
Add the onion, carrots, and celery. Cook for 6 to 8 minutes, until the vegetables begin to soften. Add the garlic and tomato paste and cook for another minute.
Pour in the red wine, scraping up any browned bits from the bottom of the skillet. Simmer for 4 to 5 minutes, until the wine has reduced by about half. Sprinkle the flour over the mixture and stir for 1 minute. Slowly pour in the broth while stirring, then add the Worcestershire sauce, rosemary, and thyme. Simmer for 6 to 8 minutes, until the filling is rich and thick enough to hold its shape on a spoon, season to taste.
Assemble and bake
Spread the lamb filling evenly in a 9 by 13 inch baking dish, or leave it in the skillet if it is oven-safe. Spoon the mashed potatoes over the top and spread them to the edges. Use a fork to make ridges across the surface so the potatoes brown well.
Bake for 20 to 25 minutes, until the filling bubbles around the edges. For a more deeply browned top, broil for 2 to 3 minutes while watching closely. Let the shepherd’s pie rest for 10 minutes before serving.
Make the shepherd’s pie ahead
Assemble the pie up to one day in advance, cover it, and refrigerate. When baking it directly from the refrigerator, allow approximately 10 to 15 additional minutes and confirm that the center is hot before serving.
Leftovers can be refrigerated in a covered container and reheated until steaming hot. The flavors often become even better the next day.
Safe Cooking Temperatures for Lamb
Use a food thermometer rather than relying only on color or cooking time.
Whole cuts of lamb, including racks and roasts, should reach at least 145°F in the thickest portion and rest for at least three minutes before carving.
Ground lamb should reach 160°F.
Slow-braised shoulder, leg, and shanks will normally reach a higher internal temperature before becoming fork-tender.
Keep the thermometer tip away from the bone for the most accurate reading.
