It’s a celebratory centerpiece that captures the rustic, bold spirit of Southern Brazilian gaucho culture.

🥗 Ingredients

The Meat

  • 5-6 pounds Leg of Lamb (bone-in, fat cap trimmed to 1/4 inch)

Vinh d'Alhos (The Marinade)

  • 1/2 cup Cachaça (clear Brazilian sugar cane spirit)
  • 1 cup Dry White Wine (sauvignon blanc or pinot grigio)
  • 8 cloves Garlic (smashed and minced)
  • 1 Yellow Onion (grated or finely pureed)
  • 3 sprigs Fresh Rosemary (leaves finely chopped)
  • 1/2 cup Fresh Mint (tightly packed and chopped)
  • 2 tablespoons Fresh Lime Juice (about 1 large lime)
  • 2 tablespoons Coarse Sea Salt (use high-quality Sal Grosso if available)
  • 1 tablespoon Black Peppercorns (coarsely cracked)
  • 1 teaspoon Smoked Paprika (for a subtle smoky depth)
  • 3 pieces Bay Leaves (dried)

For Roasting

  • 2 large Carrots (cut into thick chunks)
  • 2 pieces Celery Stalks (cut into thick chunks)
  • 2 tablespoons Olive Oil (extra virgin)

👨‍🍳 Instructions

  1. 1

    Using a sharp paring knife, make small 1-inch deep incisions all over the leg of lamb. This allows the marinade to penetrate deep into the muscle fibers.

  2. 2

    In a medium bowl, whisk together the cachaça, white wine, minced garlic, grated onion, lime juice, chopped rosemary, mint, sea salt, cracked pepper, and smoked paprika.

  3. 3

    Place the lamb in a large, non-reactive roasting pan or a heavy-duty sealable bag. Pour the marinade over the meat, ensuring it enters the incisions. Add the bay leaves and massage the liquid into the meat for 2-3 minutes.

  4. 4

    Cover tightly and refrigerate for at least 12 hours, though 24 hours is ideal for the most authentic and tender results. Flip the lamb halfway through the marinating process.

  5. 5

    Remove the lamb from the refrigerator 1 hour before cooking to bring it to room temperature, which ensures even roasting.

  6. 6

    Preheat your oven to 325°F (165°C). In a large roasting pan, create a 'bed' for the lamb using the carrot and celery chunks.

  7. 7

    Place the lamb on top of the vegetables. Pour the remaining marinade from the bag into the bottom of the pan. Drizzle the top of the lamb with olive oil.

  8. 8

    Cover the roasting pan tightly with heavy-duty aluminum foil. Roast for 2.5 hours. The low temperature and steam will break down the connective tissue.

  9. 9

    Remove the foil and increase the oven temperature to 400°F (200°C). Baste the lamb generously with the pan juices.

  10. 10

    Roast uncovered for another 30-45 minutes, basting every 15 minutes, until the exterior is beautifully browned and crisp (the 'pururuca' effect) and the internal temperature reaches 145°F for medium-rare or 160°F for medium.

  11. 11

    Transfer the lamb to a carving board. Tent loosely with foil and let it rest for at least 20 minutes. This is crucial for the juices to redistribute.

  12. 12

    Strain the pan juices into a small saucepan, skim off the excess fat, and simmer over medium heat for 5-8 minutes to create a concentrated jus to serve alongside.

💡 Chef's Tips

Always use a meat thermometer to avoid overcooking; lamb can go from succulent to dry very quickly. If you cannot find cachaça, you can substitute with a high-quality silver rum, though the flavor profile will be slightly sweeter. Don't skip the resting period; if you cut the meat too early, all the flavorful juices will run out onto the board. For an extra crust, mix a little honey with the pan juices during the final 15 minutes of uncovered roasting. If you prefer a more 'fall-off-the-bone' texture, cook at 300°F for 5 hours while covered, then brown at the end.

🍽️ Serving Suggestions

Serve with traditional Brazilian Arroz Branco (White Rice) and Feijão Preto (Black Beans). Accompany with 'Farofa' (toasted cassava flour) to provide a wonderful crunchy texture contrast. A fresh 'Molho à Campanha' (Brazilian vinaigrette salsa) cuts through the richness of the lamb beautifully. Pair with a bold Brazilian Cabernet Sauvignon or a classic Caipirinha to complement the herb notes. Grilled pineapple slices dusted with cinnamon make for an authentic and refreshing side dish.
