Ingredients
- 10 lb Leg of Lamb, Bone‑In (Trimmed, skin left on)
- 20 pieces Garlic Cloves (Halved for stuffing into slits)
- 8 sprigs Fresh Rosemary (6 for stuffing, 2 for garnish)
- 0.5 cup Extra Virgin Olive Oil (Divided: light coating + rub base)
- 1 Tbsp Maple Syrup (Pure New England maple syrup)
- 2 Tbsp Kosher Salt (For pre‑salting and rub)
- 1 tsp Black Peppercorns (Whole, for mortar)
- 1 tsp Pink Peppercorns (Whole, for mortar)
- 1 tsp Coriander Seeds (Whole, for mortar)
- ½ tsp Cumin Seeds (Whole, for mortar)
- ½ tsp Smoked Paprika (Adds subtle smokiness)
- ½ tsp Dried Oregano
- ½ tsp Dried Sage
- ¼ tsp Yuzu Powder (Japanese citrus powder for brightness)
Instructions
Pre‑Salt the Lamb
Generously rub the leg of lamb with 2 Tbsp kosher salt, covering all surfaces. Place on a rack in the refrigerator for at least 2 hours, preferably overnight, then let sit at room temperature for 2 hours before cooking.
Time: PT2H
Trim and Slit the Meat
Trim any excess fat or sinew. Using a sharp knife, make shallow slits about 1‑inch apart across the surface. Insert half a garlic clove and a small rosemary sprig into each slit; sprinkle a pinch of salt inside each opening.
Time: PT10M
Prepare the Spice Rub
In a mortar, combine the remaining garlic cloves, rosemary leaves (from 2 sprigs), black peppercorns, pink peppercorns, coriander seeds, cumin seeds, smoked paprika, dried oregano, dried sage, and yuzu powder. Grind until a coarse paste forms. Transfer to a bowl, stir in ½ cup olive oil and 1 Tbsp maple syrup until well blended.
Time: PT10M
Preheat the Oven
Set the oven to 425°F (218°C) and allow it to fully preheat.
Time: PT10M
Temperature: 425°F
Initial Roast
Place the lamb on the rack in the roasting pan, bone side down. Drizzle a thin layer of olive oil over the surface. Roast uncovered for 20 minutes at 425°F.
Time: PT20M
Temperature: 425°F
First Baste
Remove the pan, brush half of the prepared rub over the entire surface, making sure to get into the slits. Return the lamb to the oven, reduce temperature to 350°F (177°C).
Time: PT5M
Temperature: 350°F
Continue Roasting to Target Temperature
Roast at 350°F, checking the internal temperature with a probe thermometer after 30 minutes. When the thickest part reaches 140°F (60°C) for medium‑rare, brush the remaining rub over the meat.
Time: PT30M
Temperature: 350°F
Rest the Lamb
Transfer the lamb to a cutting board or a warm resting rack. Tent loosely with foil and let rest for 30 minutes. This allows juices to redistribute and the internal temperature to rise to about 145°F (63°C).
Time: PT30M
Carve and Serve
Slice the leg against the grain into ½‑inch thick slices. Arrange on a platter, garnish with fresh rosemary sprigs. Serve with pan drippings or a simple jus if desired.
Time: PT10M

Chef Tips from the Video
- Bone‑in lamb imparts extra flavor and helps the meat cook evenly.
- A quick high‑heat start (425°F) creates a beautiful caramelized crust.
- Maple syrup adds a subtle sweetness that balances the peppery rub.
Troubleshooting
The crust is too dark before the interior reaches target temperature.
Tent the lamb loosely with foil and lower oven temperature to 325°F until the center is done.
Meat is dry after cooking.
Make sure the lamb was salted ahead of time and rested after roasting; over‑cooking beyond 145°F will also dry it out.
Garlic pieces didn’t infuse the meat.
Make deeper slits (about ½‑inch) and press the garlic halves firmly into each opening.
Storage
Refrigerator: Store sliced or whole lamb in an airtight container for up to 4 days.
Freezer: Wrap tightly in freezer‑grade foil and freeze for up to 2 months.
Room temperature: Do not store at room temperature for more than 2 hours.
Make-Ahead Tips
- Salt the lamb up to 24 hours in advance; keep uncovered in the fridge for a drier surface that crisps better.
- Prepare the spice rub and store in an airtight jar for up to 3 days.
- You can pre‑stuff the garlic and rosemary slits and keep the lamb wrapped in the fridge until ready to roast.
Frequently Asked Questions
What is the cultural significance and history of roasted leg of lamb with garlic and rosemary in New England cuisine?
Roasted leg of lamb has long been a centerpiece for spring holidays in New England, especially Easter. The combination of garlic, rosemary, and a touch of maple syrup reflects the region’s colonial heritage (garlic and rosemary from European settlers) and its abundant maple production.
What traditional regional variations of lamb roast exist in American versus Mediterranean cooking?
In the United States, especially New England, lamb is often paired with maple or honey for a sweet‑savory profile. Mediterranean versions typically use olive oil, lemon, and herbs like mint or oregano without the maple element, focusing on brighter acidity.
How is a classic New England roasted leg of lamb traditionally served?
It is usually sliced thick, arranged on a platter with fresh rosemary sprigs, and served alongside roasted root vegetables, a simple jus made from pan drippings, and sometimes a side of minted peas or a grain salad.
What occasions or celebrations is roasted leg of lamb traditionally associated with in New England culture?
The dish is a staple for Easter brunches, spring family gatherings, and holiday meals such as Passover or Mother’s Day, where a whole roast symbolizes abundance and celebration.
How does roasted leg of lamb fit into the broader New England culinary tradition?
New England cuisine emphasizes hearty, seasonal proteins and the use of local sweeteners like maple syrup. This lamb roast embodies those principles by marrying rich, fatty meat with a sweet‑spicy rub and fresh herbs.
What are the authentic traditional ingredients for a New England style roasted leg of lamb versus acceptable substitutes?
Authentic ingredients include fresh rosemary, garlic, black and pink peppercorns, maple syrup, and extra‑virgin olive oil. Acceptable substitutes are dried rosemary (1 tsp), honey for maple syrup, and avocado oil in place of olive oil.
What other New England dishes pair well with this roasted leg of lamb?
Pair it with classic sides like roasted carrots and parsnips, creamy mashed potatoes, a warm grain salad with dried cranberries, or a simple green bean almondine.
What makes this roasted leg of lamb special or unique in New England cuisine?
The use of maple syrup in the rub adds a regional sweetness rarely found in traditional lamb preparations, while the generous garlic‑stuffed slits deliver an intense, aromatic flavor that sets it apart from standard herb‑only roasts.
What are the most common mistakes to avoid when making roasted leg of lamb with this recipe?
Common errors include skipping the pre‑salting step, over‑cooking past 145°F, and not letting the meat rest, which all lead to a dry, less flavorful roast. Also, failing to monitor the internal temperature can result in an under‑ or over‑done crust.
Why does this recipe call for a high‑heat start at 425°F before lowering to 350°F?
The initial high heat quickly renders the lamb’s exterior fat and creates a caramelized crust. Reducing the temperature afterward allows the interior to cook gently to the desired medium‑rare doneness without burning the crust.
What does the YouTube channel Brad Leone specialize in?
Brad Leone’s YouTube channel, "Making It," focuses on fermentation, wild‑culture cooking, and approachable, science‑backed techniques for home cooks, often featuring rustic, flavor‑forward recipes like this lamb roast.
How does Brad Leone’s approach to cooking lamb differ from other cooking channels?
Brad Leone emphasizes hands‑on experimentation, using simple tools like a mortar and pestle, and incorporates unexpected ingredients (like maple syrup) while explaining the chemistry behind each step, unlike many channels that follow strict, textbook methods.
