Understanding the Butterflied Leg of Lamb
What Is a Butterflied Leg of Lamb?
A butterflied leg of lamb involves carefully slicing the entire leg of lamb open and spreading it flat, similar to opening a book. This technique results in a thinner, more uniform piece of meat that cooks more quickly and evenly. The process involves removing the bone and excess fat, then opening and flattening the meat, which allows for better marination, quicker cooking, and a more attractive presentation.
Why Choose a Butterflied Leg of Lamb?
Opting for a butterflied leg of lamb offers several advantages:
- Faster Cooking Time: The thinner, flattened meat cooks more evenly, reducing roasting time.
- Enhanced Flavor Absorption: Marinating or seasoning can penetrate the meat more effectively.
- Beautiful Presentation: When served sliced, the cross-section reveals a vibrant, juicy interior.
- Versatility: Ideal for grilling, roasting, or stuffing, making it a versatile choice.

Choosing the Right Lamb
Selecting high-quality lamb is essential for a flavorful roast. Look for:
- Freshness: Bright red color with firm texture.
- Grade: Prime or Choice grades typically offer better marbling.

Step-by-Step Preparation
1. Butterflying the Leg of Lamb
- Lay the lamb on a clean cutting board.
- Use a sharp knife to locate the bone if it’s still attached; carefully cut along the bone to remove it.
- Turn the meat over and make a lengthwise incision along the thickest part.
- Open the meat like a book, flattening it evenly.
2. Trimming Excess Fat
- Remove large chunks of fat if desired, but leave a thin layer for flavor and moisture.
3. Marinating or Seasoning
- Prepare a marinade or spice rub based on your flavor preferences.
- Common ingredients include garlic, rosemary, thyme, olive oil, lemon juice, salt, and pepper.
- Rub the marinade all over the meat or soak it for several hours or overnight for maximum flavor.
4. Optional Stuffing
- For added flavor or presentation, consider stuffing the butterflied lamb with herbs, garlic, or even a bread-based stuffing before rolling and tying.

Roasting is the most traditional and straightforward method for cooking butterflied leg of lamb.
Steps:
- Preheat your oven to 375°F (190°C).
- Arrange the lamb on a roasting tray, fat side up.
- Use a meat thermometer to monitor internal temperature.
- Roast for approximately 20-25 minutes per pound for medium rare, or until the desired doneness.

- Cook at a low temperature (around 300°F / 150°C) for 2-3 hours.
- Use flavorful liquids like broth, wine, or tomato sauce.
