Story of the Dish
Roasted lamb belongs naturally to the pastoral cooking of inland Marche, particularly the mountain and hill areas where sheep farming has long shaped the table. The classic flavor vocabulary is straightforward: garlic, rosemary, sage, olive oil and dry white wine. Potatoes roast alongside and absorb some of the meat juices. The dish succeeds through browning and timing rather than a complicated marinade or sauce.
Bone-in shoulder and leg pieces are excellent because the bone contributes flavor and protects the meat. Potatoes need a head start so they can color instead of steaming under the lamb. The roast begins hot for surface color, then finishes at a lower temperature. Wine belongs around the meat, not continuously over the browned crust.

Ingredients
4 lb (1.8 kg) bone-in lamb shoulder and leg pieces
5 garlic cloves, lightly crushed
4 rosemary sprigs, divided
10 sage leaves
1/4 cup (60 ml) extra virgin olive oil
1 cup (240 ml) dry white wine, divided
1 1/2 tsp fine sea salt
1 tsp freshly ground black pepper
2 1/2 lb (1.13 kg) Yukon Gold potatoes, cut into large wedges
3 tbsp extra virgin olive oil for potatoes
2 garlic cloves for potatoes
1 rosemary sprig for potatoes
1/2 tsp fine sea salt for potatoes
1/2 cup (120 ml) light lamb or chicken stock, only if needed
Step-by-Step Preparation
Pat lamb dry and place in a nonreactive container. Add crushed garlic, two rosemary sprigs, sage, olive oil, black pepper and half the wine. Massage the aromatics over the meat, cover and refrigerate for 2 hours. Remove about 30 minutes before roasting and season with salt only then.
Heat oven to 425°F (220°C). Toss potatoes with their olive oil, garlic, rosemary and salt. Spread in one layer in a large roasting pan and roast alone for 15 minutes. This head start dries the surface and begins browning before the lamb releases juices.
Remove pan, turn potatoes and arrange lamb pieces among them with as much meat exposed as possible. Pour the marinade into the bottom of the pan, not over the top surfaces. Return to the oven for 20 minutes at 425°F.
Lower oven to 375°F (190°C). Pour remaining white wine around the lamb. Continue roasting 35 to 50 minutes, turning potatoes halfway. Check individual meat pieces because shoulder and leg portions can vary in thickness.
Use an instant-read thermometer in the thickest edible portions away from bone. Lamb doneness preference varies, but follow appropriate safe cooking guidance for the cut and service. Remove smaller pieces as they reach the desired safe doneness rather than overcooking them while larger pieces finish.
If the pan becomes dry before the meat is ready, add stock a few tablespoons at a time. Do not flood the potatoes. During the final 8 to 10 minutes, increase oven to 425°F if either lamb or potatoes need additional surface color.
Transfer lamb to a warm board and rest for 15 minutes. Leave potatoes in the switched-off oven with the door slightly open if they need to stay warm without steaming. Skim excessive fat from the roasting pan.
Place roasting pan over medium heat, add a small amount of stock if necessary and scrape the caramelized deposits. Reduce for 3 to 5 minutes to a natural jus. Serve lamb with crisp potatoes and a modest spoonful of jus.
Professional Technique
The potatoes and lamb cannot start at the same time if you want deeply roasted potatoes. The 15-minute head start creates surface dehydration and color before lamb juices enter the pan. Large wedges are also less likely to collapse during the later turning.
Wine should deglaze and perfume, not wash away browning. Adding it around the meat preserves the crust while still allowing alcohol to evaporate and mingle with the pan juices. Repeated basting is unnecessary and softens the exterior.
Professional Kitchen Notes
Use the largest roasting pan that fits comfortably in the oven. Crowding creates steam and prevents potatoes from crisping. If the pan is packed edge to edge, roast potatoes on a second tray rather than accepting pale results.
Different lamb pieces should be treated independently. A thin rib or small shoulder piece can finish earlier than a thick leg section. Remove pieces as ready and reunite them after the final jus is made.
Rosemary is powerful under high heat. Whole sprigs can be removed if they become dark. The goal is an herb-scented roast, not a crust of burnt needles. Sage should remain mostly in the pan juices and marinade rather than covering every potato.
The exact lamb cut changes both timing and the ideal endpoint. Shoulder pieces contain more connective tissue and tolerate longer roasting, while pieces from the leg are leaner and can dry if they remain in the pan only because the shoulder is not yet tender. Check pieces independently with an instant-read thermometer and by feel near the bone. Remove the leaner pieces when ready, keep them warm, and return them to the platter after the final jus is made.
Potato variety and spacing matter as much as the lamb. Yukon Gold or another medium-starch potato browns while still holding its shape. Cut wedges large enough to survive turning and leave visible pan surface between them. If potatoes are packed tightly, moisture from the lamb and wine creates a steaming environment. When the roasting pan cannot provide enough space, use a second tray for part of the potatoes rather than accepting soft pale edges.
The pan jus should be finished after excess lamb fat is skimmed. Leave a thin film because it carries rosemary and roasted-meat aroma, but remove large clear pools before deglazing the fond with stock. Taste the reduced jus for acidity before adding anything else. If the wine has become too sharp, a few spoonfuls of unsalted stock and another gentle reduction are preferable to sugar. The final jus should taste roasted and savory, with wine as a supporting note rather than a separate sour flavor.
Chef Tips
Use bone-in lamb for flavor and moisture.
Give potatoes a roasting head start.
Keep wine around, not over, the meat.
Use a wide uncrowded pan.
Check individual pieces for doneness.
Rest lamb before serving.
Common Mistakes
Starting raw potatoes and lamb together in a crowded pan.
Pouring cold wine repeatedly over the browned surface.
Cooking every lamb piece to the timing of the largest one.
Using excessive rosemary.
Skipping the rest and losing juices.
Serving and Presentation
Arrange lamb on a warm platter with potatoes around it and jus served sparingly. Sautéed chicory or other bitter greens provide a useful contrast to lamb fat and roasted potatoes.
Do not hide the browned meat beneath sauce. The crust is part of the dish. A few fresh herb leaves are enough garnish if desired.
Wine Pairing
Rosso Conero: its Montepulciano structure, dark fruit and savory profile are a strong regional match for roasted lamb. Rosso Piceno: balanced acidity and red fruit work well with herbs and potatoes. Verdicchio dei Castelli di Jesi: a structured white alternative for diners who prefer white wine with herb-driven roast lamb.
Storage and Reheating
Refrigerate lamb and potatoes separately for up to 3 days, keeping jus in another container. This prevents potatoes from absorbing moisture and becoming soft during storage.
Reheat lamb covered at 325°F (165°C) with a little jus. Reheat potatoes uncovered at 425°F (220°C) to restore crispness. Combine only at service.

Final Note
Roasted lamb should still taste primarily of lamb. Garlic, sage, rosemary and wine belong in support, and the potatoes should carry the pan flavor without becoming soft or greasy.
The final target is dark roasted edges, juicy meat, crisp potatoes and only enough concentrated jus to connect the plate.
