One of my favorite Sunday Roasts Growing Up

My wife and I prepared this meal for her brother and his son while they were visiting us in Park City. East coasters this time.

We served it with grilled polenta slices, roasted acorn squash, and mixed greens salad. I believe we served a Rosemont Estate Shiraz/Cabernet from Australia.

What is a bone-in leg of lamb?

In culinary terms, a "bone-in leg of lamb" refers to a specific cut of lamb meat. The hind leg of a lamb or young sheep is typically sold with the bone intact, providing added flavor and juiciness to the meat during cooking. The bone-in leg of lamb is a popular choice for roasting and is often a centerpiece for special occasions and festive meals.

The bone-in leg of lamb can be prepared and cooked in various ways, such as roasting, grilling, or braising, depending on personal preferences and the desired level of doneness. The bone imparts flavor to the surrounding meat during cooking and helps retain moisture, resulting in a tender and flavorful dish.

When purchasing a bone-in leg of lamb, you can ask your butcher to trim and prepare it according to your specific requirements. Proper cooking instructions and recommended internal temperature guidelines are essential to ensure a safe and delicious dining experience. Additionally, pairing the meat with various herbs, spices, and accompaniments can enhance its taste and presentation.

What are the advantages of cooking a bone-in leg of lamb?

Enhanced flavor: The bone imparts a rich, savory flavor to the meat as it cooks. The marrow within the bone adds depth and richness to the lamb, enhancing its taste and making it more satisfying.
Moisture retention: The bone acts as a natural insulator, helping retain moisture in the meat during cooking. This results in a juicier and more tender leg of lamb, reducing the risk of it becoming dry or tough.
Even cooking: The bone helps distribute heat evenly throughout the meat, ensuring consistent cooking. This can prevent certain leg parts from overcooking while other parts remain undercooked.
Aesthetics and presentation: Cooking a bone-in leg of lamb creates an impressive and visually appealing presentation. The bone acts as a handle, making it easier to carve and serve the meat at the table, adding an element of elegance to the meal.
Better bone broth and stock: After cooking the leg of lamb, the bone can be used to make a flavorful broth or stock. The leftover bones and meat scraps can be simmered with vegetables and herbs to create a delicious base for soups or sauces.
Cooking versatility: A bone-in leg of lamb can be prepared using various cooking methods, such as roasting, grilling, or braising, depending on personal preferences and desired flavors. The bone provides a stable structure during cooking and can be beneficial when using specific cooking equipment.
Nutrient-rich bone marrow: It offers additional nutritional benefits if you enjoy the marrow inside the bone. Bone marrow is rich in healthy fats, vitamins, and minerals, producing a well-rounded and nutritious meal.

Cooking a bone-in leg of lamb not only adds to the taste and texture of the dish but also enhances the overall dining experience, making it a popular choice for special occasions and gatherings.

What about the cost compared to the boneless leg of lamb?

The cost of a bone-in leg of lamb is generally lower than that of a boneless leg of lamb. This price difference is primarily due to the additional labor and processing involved in deboning the meat. When you purchase a boneless leg of lamb, you are paying for the convenience of not having to deal with the bone and the ease of preparation.

On the other hand, a bone-in leg of lamb requires less handling and processing, as it is sold with the bone still intact. This makes it a more cost-effective option for those looking to save money while still enjoying the flavors and benefits of cooking with the bone.

However, it's important to note that the cost difference may vary based on several factors, including the region, the cut of meat, and the specific market conditions.

Additionally, the price gap between bone-in and boneless leg of lamb might be insignificant, so it's essential to check with your local butcher or meat supplier to get the most accurate and up-to-date pricing information.

When deciding between bone-in and boneless leg of lamb, consider your budget, cooking preferences, and the dish you plan to prepare. While a bone-in leg of lamb may offer some cost savings, a boneless leg

Roast Leg of Lamb

Prep Time30

Cook Time1 45

Resting Time15

Total Time2 30

Course: Main Course

Cuisine: American

Keyword: leg of lamb

Servings: 8 servings

Ingredients

1 leg of lamb bone-in 5 to 7 pounds
6 cloves garlic sliced thinly
2 tablespoons fresh rosemary chopped
2 tablespoons fresh thyme chopped
2 tablespoons olive oil
2 tablespoons Dijon mustard
salt and pepper to taste

Instructions

Take the bone-in leg of lamb out of the refrigerator and let it sit at room temperature for about 30 minutes to an hour before roasting. Preheat your oven to 375°F.
Pat the leg of the lamb dry with paper towels to remove any excess moisture. This helps the seasoning stick better and promotes better browning during roasting.
With a sharp knife, make small slits all over the lamb. Insert the sliced garlic into the slits.
Mix the chopped rosemary, thyme, olive oil, Dijon mustard, salt, and black pepper in a small bowl to make a flavorful herb rub.
Rub the herb mixture all over the lamb, making sure to coat it thoroughly, including the nooks and crannies. This will infuse the meat with aromatic flavors.
Place the seasoned leg of lamb on a roasting rack in a roasting pan, bone-side down. The roasting rack elevates the meat and circulates hot air around it, promoting even cooking.
Roast the lamb in the preheated oven for about 1.5 to 2 hours, depending on your desired level of doneness. Use a meat thermometer inserted into the thickest part of the meat, away from the bone, to check the internal temperature. For medium-rare, aim for around 135°F (57°C), and for medium, around 145°F (63°C). Keep in mind that the temperature will rise a few degrees while resting.
Once the lamb reaches your desired level of doneness, remove it from the oven and tent it loosely with aluminum foil. Allow the lamb to rest for about 15 to 20 minutes. Resting allows the juices to redistribute, making the meat more tender and flavorful.
Carve the roasted bone-in leg of lamb and serve it with your favorite side dishes.

Notes

Cooking times may vary depending on your oven and the size of the lamb leg, so it's always a good idea to use a meat thermometer to ensure accurate doneness.
