Choosing the Right Butterflied Leg of Lamb
Before diving into the roasting process, it’s essential to select a quality butterflied leg of lamb. This cut is typically a whole leg of lamb that has been sliced open and flattened, making it ideal for even cooking and quicker preparation.
What is a Butterflied Leg of Lamb?
A butterflied leg of lamb is a whole leg that has been sliced horizontally and opened out flat. This technique allows for more uniform cooking and makes it easier to marinate or season thoroughly. It’s a popular choice for roasting because it cooks evenly, resulting in tender, flavorful meat.
How to Choose a Good Piece
When selecting a butterflied leg of lamb, consider the following:
- Quality: Look for fresh, bright red meat with firm texture. The fat should be white or creamy, not yellow.
- Size: Typically weighs between 2 to 4 pounds, perfect for family meals or small gatherings.
- Bone-in or boneless: Bone-in cuts tend to be more flavorful, but boneless may be easier to carve.
- Source: Purchase from a reputable butcher or supplier who can provide information about the lamb’s origin and diet.

Preparing the Butterflied Leg of Lamb
Proper preparation is crucial for ensuring your roast turns out flavorful and tender.
Thawing and Resting
If your lamb is frozen, allow it to thaw in the refrigerator for at least 24 hours. Once thawed, take the meat out of the fridge about 30-60 minutes before cooking to bring it to room temperature. This step promotes even cooking.
Trimming Excess Fat and Silver Skin
Use a sharp knife to trim away any excess fat or silver skin. Removing this connective tissue helps the seasoning penetrate better and prevents the meat from becoming overly greasy.
Marinating and Seasoning
Marinating enhances flavor and tenderness. For a simple yet flavorful marinade:
- Combine olive oil, minced garlic, fresh rosemary, thyme, salt, pepper, and a splash of lemon juice.
- Rub the marinade all over the butterflied lamb, ensuring even coverage.
- Cover and refrigerate for at least 2 hours, preferably overnight for maximum flavor.
Alternatively, if you prefer a dry rub:
- Mix salt, black pepper, garlic powder, rosemary, and paprika.
- Apply generously over the meat before roasting.

The roasting process is the heart of this guide. Correct technique and timing are vital for achieving juicy, tender meat.
Prepping Your Oven and Equipment
- Preheat your oven to 375°F (190°C).
- Use a roasting pan with a rack or a sturdy baking sheet.

Roasting Procedure
1. Remove the marinated lamb from the refrigerator and let it sit at room temperature for about 30 minutes.
2. Place the lamb on the rack or baking sheet, fat side up.
3. Insert a meat thermometer into the thickest part of the meat, avoiding the bone if present.
4. Roast in the preheated oven, basting occasionally with pan juices if desired.
