Roast Leg of Lamb: A French Kitchen Classic

The aroma of roasting lamb always transports me back to my grandmother’s farmhouse in Provence. The whole house would fill with the scent of garlic, herbs, and slowly caramelizing meat. As a child, I’d eagerly await the moment when the lamb, glistening and fragrant, was brought to the table, surrounded by golden potatoes that had soaked up all the delicious drippings. It was more than just a meal; it was a celebration of family, tradition, and the simple pleasures of life. Today, I recreate that feeling in my own kitchen, bringing a touch of the French countryside to my home.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 2 hours 15 minutes to 3 hours 15 minutes (depending on desired doneness and size of lamb)
• Total Time: 2 hours 35 minutes to 3 hours 35 minutes
• Servings: 6-8
• Yield: 1 roast leg of lamb with potatoes
• Dietary Type: Generally Gluten-Free and Dairy-Free

Ingredients

• 1 leg of lamb
• 1 garlic clove, sliced and cut into narrow slivers (1 large clove, more if cloves are small)
• ½ lemon, juice of
• 1 teaspoon salt
• 2 teaspoons black pepper, coarse ground
• ½ cup olive oil
• ½ cup herbes de provence, dried (See note at end of directions)
• 4-6 potatoes, sliced about 1 inch thick
• ½ teaspoon salt
• ½ teaspoon black pepper
• ¼ cup olive oil
• ½ cup beef stock

Equipment Needed

• Oven
• Oven pan
• Another oven pan (for potatoes)

Instructions

1. Pre-heat oven to 500°F.
2. Use an oven pan while you are preparing the leg of lamb (you will remove the joint from the pan when you place it in the oven). This keeps your counters clean.
3. Using a sharp knife, pierce the leg of lamb all over. Insert the slivers of garlic into each incision. The more garlic, the better, in my opinion!
4. In a small bowl, mix together the juice of ½ lemon, 1 teaspoon of salt, 2 teaspoons of coarse ground black pepper, and ½ cup of olive oil.
5. Using your hands, thoroughly wipe the lemon-garlic-oil mixture all over the leg of lamb, ensuring every part is coated.
6. Pat the herbes de provence all over the leg of lamb, pressing them gently to form a “crust.” Be generous with the herbs; they are key to the dish’s flavor.
7. Lay the sliced potatoes in another oven pan.
8. Sprinkle the potatoes with ½ teaspoon of salt and ½ teaspoon of black pepper.
9. Drizzle the potatoes with ¼ cup of olive oil.
10. Toss the potatoes around (using your hands is easiest) to ensure the slices are well coated with the oil and seasonings.
11. Pour the ½ cup of beef stock over the seasoned potatoes in the pan.
12. Place the uncovered leg of lamb directly onto the oven shelf/grid, with the oven pan of potatoes below. This allows the lamb juices to drip down onto the potatoes as it roasts, infusing them with incredible flavor. This is the magic of this recipe.
13. Roast the leg of lamb for 20 minutes at 500°F. This initial blast of high heat helps to create a flavorful crust.
14. After 20 minutes, reduce the oven heat to 325°F.
15. Continue roasting the leg of lamb until it reaches your desired level of doneness. Use a meat thermometer to check the internal temperature.
    • For medium-rare: Roast for 20-25 minutes per pound of lamb, plus an additional 20 minutes.
    • For well-done: Roast for 25-30 minutes per pound of lamb, plus an additional 25 minutes.
16. Once cooked, remove the leg of lamb from the oven and let it rest for at least 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful roast. While the lamb rests, you can tent it loosely with foil to keep it warm.

Expert Tips & Tricks

• Don’t skip the resting period! It’s crucial for achieving a juicy and tender roast.
• If the potatoes start to brown too quickly before the lamb is done, cover the pan loosely with foil.
• For extra flavor, consider adding a splash of red wine to the beef stock before pouring it over the potatoes.
• If you don’t have beef stock, chicken stock works as a suitable substitute.
• To ensure even cooking, use a meat thermometer to monitor the internal temperature of the lamb. Insert it into the thickest part of the roast, avoiding bone.
• Consider making a quick pan sauce with the lamb drippings. After removing the lamb and potatoes, pour the drippings into a saucepan, skim off any excess fat, and simmer over medium heat until slightly thickened. Season to taste with salt and pepper.

Serving & Storage Suggestions

Serve the roast leg of lamb immediately after carving, accompanied by the golden, flavorful potatoes. A simple green salad or roasted vegetables make excellent side dishes.

Leftover roast leg of lamb can be stored in an airtight container in the refrigerator for up to 3-4 days. It can also be frozen for up to 2-3 months. To reheat, slice the lamb and warm it gently in a skillet with a little olive oil or gravy. Alternatively, you can reheat it in the oven at a low temperature (around 300°F) until heated through. The potatoes can also be reheated in the oven or in a skillet.

FAQs (Frequently Asked Questions)

Q: How do I prevent the leg of lamb from drying out during roasting?
A: Roasting at a high temperature initially helps to sear the outside of the lamb, sealing in the juices. Also, resting the lamb after cooking allows the juices to redistribute, resulting in a more tender and moist roast.

Q: Can I use bone-in or boneless leg of lamb for this recipe?
A: Either bone-in or boneless leg of lamb can be used. Bone-in will typically be more flavorful, but boneless is easier to carve. Adjust cooking time slightly based on the thickness of the roast.

Q: What is the best way to carve a leg of lamb?
A: Use a sharp carving knife. Rest the lamb, then position it with the shank bone facing towards you. Slice down towards the bone, then run the knife along the bone to release the slices.

Q: Can I prepare the potatoes ahead of time?
A: You can slice the potatoes a few hours in advance and keep them submerged in cold water to prevent browning. Drain them well before adding them to the roasting pan.

Q: What wine pairs well with roast leg of lamb?
A: A full-bodied red wine, such as Cabernet Sauvignon, Merlot, or Syrah, pairs beautifully with roast leg of lamb.
