Method
Spit-Roasted Leg of Lamb
- 1
Prepare the lamb
Remove lamb from refrigerator 1 hour before cooking to come to near room temperature. Pat dry with paper towels. Using a small sharp knife, score the fat in a diamond pattern about 1/4 inch deep.
- 2
Make herb marinade
In a bowl, combine minced garlic, chopped rosemary, chopped thyme, lemon zest, kosher salt, black pepper, and olive oil. Whisk until emulsified.
- 3
Marinate
Rub the herb marinade all over the lamb, working it into the scored fat and any exposed meat. If time allows, wrap and refrigerate for 2–6 hours or overnight for deeper flavor. Bring back to room temperature 1 hour before roasting.

Preheat and roast
Preheat the spit-roaster or oven to 375°F (190°C). If using a spit, start rotation and set heat so the exterior browns evenly. Roast until an instant-read thermometer inserted into the thickest part (not touching bone) reads 125°F (52°C) for medium-rare (approximately 1.5–2 hours for a 5 lb leg), or 135°F (57°C) for medium. Baste every 20–30 minutes with melted butter mixed with a splash of white wine for gloss and flavor.

Rest
Remove lamb from spit or oven when 5–7°F below target temp; tent loosely with foil and rest for 20–25 minutes. Carryover cooking will bring it to the final temperature and juices will redistribute.

Carve
Transfer to a cutting board, discard twine and forks, and carve slices across the grain to desired thickness. Reserve resting juices for the jus if any.

Roast the garlic
Preheat oven to 400°F (200°C). Halve the garlic heads horizontally, drizzle cut sides with olive oil, sprinkle a pinch of salt, wrap loosely in foil and roast for 30–35 minutes until cloves are very soft and golden. Squeeze roasted garlic into a small bowl and mash to a paste.

Add stock and herbs
Stir in the beef or lamb stock, rosemary and thyme sprigs, and whole peppercorns. Simmer gently for 12–15 minutes to marry flavors and reduce slightly.
- 12
Incorporate roasted garlic
Whisk the roasted garlic paste into the sauce and simmer 2–3 more minutes. Taste and season with salt and black pepper.

Finish the jus
Strain the sauce through a fine-mesh sieve into a clean saucepan, pressing on solids to extract flavor. Return to low heat and whisk in cold cubed butter one piece at a time to create a glossy emulsion. Keep warm and hold until lamb is carved.
Herb Risotto

Prepare stock
Keep 5 cups of chicken or vegetable stock warm in a saucepan over low heat; this ensures even cooking of the rice.

- 16
Toast rice
Add the arborio rice and stir to coat with fat. Toast the rice for 1–2 minutes until edges look translucent but centers remain opaque.
- 17
Deglaze
Pour in the 1/2 cup dry white wine and stir until the wine is mostly absorbed.
- 18
Cook risotto
Begin adding warm stock, one ladleful (about 1/2 cup) at a time, stirring frequently. Wait until each addition is mostly absorbed before adding the next. Continue this process for 18–22 minutes, or until rice is creamy and al dente. You may not need all the stock; stop when texture is correct.
