Understanding Butterflied Leg of Lamb
What is a Butterflied Leg of Lamb?

This technique creates an even surface that cooks uniformly and allows for easy marinating and stuffing. The result is a tender, flavorful cut that can be cooked quickly and sliced easily for serving.
Advantages of Butterflying the Lamb
- Even cooking: The flat shape ensures uniform heat distribution.
- Faster cooking time: Less thickness means quicker roasting or grilling.
- Marination: Increased surface area allows for better flavor absorption.
- Presentation: Looks impressive when served, especially if stuffed or rolled.
- Versatility: Suitable for various cooking methods including grilling, roasting, and pan-searing.
Selecting the Perfect Butterflied Leg of Lamb
Choosing the Right Cut
When purchasing a butterflied leg of lamb, consider the following:
- Freshness: Look for bright, firm meat with a clean smell.
- Size: A typical butterflied leg weighs between 4 to 8 pounds, depending on your needs.
- Quality: Opt for grass-fed or organic if available for better flavor and tenderness.
- Marbling: Ensure the meat has a good amount of intramuscular fat for flavor and juiciness.
Preparation Before Buying
- Ask your butcher: Many butchers will prepare the leg for you, or you can buy it already butterflied.
- Homemade: If you have a sharp boning knife, you can butterfly the leg yourself by following proper techniques.
Preparing the Butterflied Leg of Lamb
Step-by-Step Process
1. Lay the lamb flat: Place the leg on a large cutting board.
2. Identify the bone and cartilage: Use your fingers to locate the bone and cartilage.
3. Make an incision: Use a sharp boning or fillet knife to carefully cut along the bone, removing it.
4. Open the meat: Once the bone is removed, spread the meat open like a book.
5. Trim excess fat and silver skin: Remove any thick fat layers or silver skin for even cooking.
6. Optional: Pound the meat: For uniform thickness, lightly pound the meat with a meat mallet to about 1.5 to 2 inches thick.
Marinating and Seasoning
Marinating enhances flavor and tenderizes the meat. Consider the following:
- Basic marinade ingredients:
- Olive oil
- Garlic (minced)
- Fresh herbs (rosemary, thyme, oregano)
- Lemon juice or vinegar
- Salt and pepper
- Marination tips:
- Marinate for at least 2 hours, preferably overnight for deeper flavor.
- Use a resealable plastic bag or covered dish to marinate evenly.
- Stuffing options:
- Chopped herbs and garlic
- Spinach and feta
- Sun-dried tomatoes and olives

Cooking Methods for Butterflied Leg of Lamb
Roasting
Roasting is a popular method that yields a tender, juicy result when done correctly.
Steps for Roasting
1. Preheat your oven: Set it to 375°F (190°C).
2. Prepare the meat: Remove from marinade, pat dry, and season with salt and pepper.
3. Optional: Roll and tie: If stuffing, roll the meat and secure with kitchen twine.
4. Sear the meat: In a hot skillet with olive oil, sear the lamb on all sides until browned (~3-4 minutes per side).
5. Transfer to oven: Place in a roasting pan.
6. Cook to desired doneness:
- Use a meat thermometer:
- Rare: 125°F (52°C)
- Medium-rare: 135°F (57°C)
- Medium: 145°F (63°C)
- Well-done: 155°F (68°C)
7. Rest the meat: Let rest for 10-15 minutes before slicing.
Grilling
Grilling imparts a smoky flavor and creates beautiful grill marks.
Steps for Grilling
1. Preheat the grill: Use medium-high heat.
2. Prepare the lamb: Remove excess marinade to prevent flare-ups, season as desired.
3. Grill the meat:
- Place the butterflied lamb directly on the grill.
- Cook for approximately 4-6 minutes per side, depending on thickness.
4. Check internal temperature and adjust cooking time accordingly.
5. Rest before slicing.
Slow Cooking or Sous Vide
For maximum tenderness, consider slow cooking or sous vide techniques, especially if you prefer a very tender result.
Slow Cooking
- Use a slow cooker with herbs and vegetables.
- Cook on low for 6-8 hours until tender.
Sous Vide
- Vacuum-seal the seasoned lamb.
- Cook at 131°F (55°C) for medium-rare for 2-4 hours.
- Finish with a quick sear on high heat for crust.
Cooking Tips and Tricks
- Use a meat thermometer: Ensures accurate doneness and prevents overcooking.
- Rest the meat: Resting allows juices to redistribute for a moist, flavorful cut.
- Slice against the grain: For tender slices, cut perpendicular to the muscle fibers.
- Manage flare-ups: When grilling, keep a close eye to prevent burning due to marinade or fat drippings.
- Experiment with flavors: Incorporate different herbs, spices, and marinades to suit your taste.
