Alternative Method: Sous Vide Machine

 Roasted Lamb and Potatoes
Indulge in the tender perfection of sous vide Roasted Lamb and Potatoes

Sous vide cooking is a technique that involves cooking food in a precisely controlled water bath for enhanced flavor and tenderness. While traditionally, Roasted Lamb and Potatoes are prepared in the oven, this alternative method using a sous vide machine offers a unique and foolproof approach to achieving melt-in-your-mouth results.

Here’s how to make Roasted Lamb and Potatoes using a sous vide machine:


  • 2 pounds (900g) lamb shoulder, boneless
  • 1 pound (450g) baby potatoes, halved
  • 4 cloves garlic, minced
  • 2 tablespoons fresh rosemary, chopped
  • 2 tablespoons olive oil
  • Salt and pepper to taste


  1. Preheat the sous vide machine to 140°F (60°C) for medium-rare doneness or adjust the temperature according to your preference.
  2. Season the lamb shoulder generously with salt, pepper, minced garlic, and chopped rosemary. Drizzle with olive oil and rub the seasonings into the meat.
  3. Place the seasoned lamb shoulder in a vacuum-sealed bag, ensuring it’s tightly sealed to prevent any water from entering.
  4. Submerge the bagged lamb shoulder in the preheated water bath of the sous vide machine. Cook for 24 hours for tender and succulent results.
  5. After 24 hours, remove the lamb shoulder from the water bath and carefully open the vacuum-sealed bag.
  6. Preheat a skillet or grill over high heat. Sear the lamb shoulder for 1-2 minutes on each side to achieve a beautiful caramelized crust.
  7. Meanwhile, in a separate pan, sauté the halved baby potatoes with a drizzle of olive oil until golden and crispy.
  8. Slice the lamb shoulder into serving portions and serve alongside the crispy roasted potatoes.
  9. Garnish with additional fresh rosemary and serve immediately.

This sous vide method ensures that the lamb shoulder cooks evenly and retains its moisture and tenderness throughout. The prolonged cooking time allows the flavors to develop, resulting in a succulent and perfectly cooked Roasted Lamb and Potatoes dish that will impress even the most discerning palates.

Cooking Tips

Discover the secrets to achieving restaurant-quality results in your own kitchen

To ensure the best results and elevate your Roasted Lamb and Potatoes dish, here are some valuable cooking tips and insights on common mistakes to avoid:

  • Achieving the Perfect Roast: For a beautifully caramelized crust on the lamb, make sure to pat the meat dry before seasoning and searing. Moisture on the surface can hinder the browning process.
  • Temperature Control: Double-check the temperature settings of your machine to ensure the lamb cooks to your desired level of doneness. A meat thermometer can also be used to verify internal temperature.
  • Resting Time: Allow the roasted lamb to rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a moist and tender final product.
  • Crispy Potatoes: To achieve perfectly crispy potatoes, consider parboiling them for a few minutes before roasting. This helps to remove excess starch, resulting in a crunchier texture.
  • Seasoning Balance: While seasoning the lamb, be mindful of the salt content, as the potatoes will also contribute to the overall flavor. Taste and adjust the seasoning accordingly to maintain a harmonious balance.

FAQs about Roasted Lamb and Potatoes (Cordero Asado)

Roasted Lamb and Potatoes
Experience the magic of slow cooking as the flavors intensify in every bite

Can I prepare the lamb shoulder in advance?
Yes, you can season and vacuum-seal the lamb shoulder a day ahead and store it in the refrigerator until ready to cook. This allows the flavors to further develop for even more depth.

How do I store leftover Roasted Lamb and Potatoes?
To store leftovers, place the cooked lamb and potatoes in separate airtight containers and refrigerate for up to 3 days. When reheating, gently warm the lamb in a skillet over low heat to retain its tenderness.

Can I use a different cut of lamb for this recipe?
While lamb shoulder is ideal for slow cooking and roasting, you can also use other cuts like leg of lamb or lamb rack. Adjust the cooking time accordingly based on the cut and thickness of the meat.

What can I serve alongside Roasted Lamb and Potatoes for a complete meal?
For a well-rounded meal, consider serving a fresh green salad, buttered peas, or a creamy cauliflower gratin as side dishes. These options add a delightful contrast and complementary flavors.
