Step‑by‑Step Instructions for Ultimate Slow-Roasted Lamb Shoulder:

Step 1: Preheat Your Oven
Begin by preheating your oven to a fiery 230°C (450°F). This initial high temperature is crucial for developing a beautiful brown crust on the Ultimate Slow-Roasted Lamb Shoulder. As the oven heats, gather your ingredients and equipment, setting the stage for a mouthwatering feast.

Step 2: Prepare the Marinade
In a small bowl, combine fresh rosemary, dried oregano, minced garlic, kosher salt, black pepper, and extra virgin olive oil to create a fragrant marinade. Use a fork or whisk to mix the ingredients thoroughly, ensuring a lovely consistency. Generously rub this mixture all over the lamb shoulder, making sure every inch is coated in flavor.

Step 3: Optional Marinating Time
If time allows, let the marinated lamb rest at room temperature for about 2 hours. This step is optional but enhances flavor infusion. Alternatively, you can refrigerate it for up to 24 hours for deeper flavor penetration. Visualize it absorbing all those aromatic herbs while you relax and enjoy the anticipation of your Ultimate Slow-Roasted Lamb Shoulder.

Step 4: Prepare the Roasting Pan
Take a roasting pan and scatter unpeeled brown onion wedges at the bottom. These will elevate the lamb and impart additional flavor to the jus. Carefully place the marinated lamb shoulder on top of the onions, then pour in enough water to cover the base, ensuring the meat stays moist during the roasting process.

Step 5: Roast at High Temperature
Pop the roasting pan into the preheated oven and roast the lamb uncovered for about 45 minutes. This high-temperature stage will start the browning process, creating an enticing crust. Keep an eye on it; the lamb should develop a beautiful golden color that will make your mouth water.

Step 6: Lower the Temperature
Once the initial roasting is complete, reduce the oven temperature to a gentle 100°C (212°F). Cover the lamb tightly with baking paper and multiple layers of foil to lock in moisture. This step is critical for ensuring that your Ultimate Slow-Roasted Lamb Shoulder becomes incredibly tender and juicy during the next phase.

Step 7: Slow-Roast for Tender Perfection
Let the lamb slow-roast in the oven for a luxurious 12 hours. During this time, the meat will break down beautifully, becoming fork-tender. Feel free to check for tenderness with forks toward the end of the cooking time; the ideal texture should be almost falling off the bone.

Step 8: Rest and Collect Juices
Once the cooking time is finished, carefully remove the lamb from the oven and transfer it to a cutting board. Let it rest for at least 15 minutes while you reserve the pan juices. These flavorful juices are essential for making a stunning jus that will enhance your Ultimate Slow-Roasted Lamb Shoulder even further.

Step 9: Make the Jus
Strain the reserved pan juices into a saucepan and bring it to a simmer over medium heat. Allow it to reduce for a while until the flavors intensify. To thicken the jus, mix cornflour with a small amount of water to create a slurry, then whisk it into the simmering liquid until it reaches your desired consistency.

Step 10: Serve with Flair
To serve your Ultimate Slow-Roasted Lamb Shoulder, use tongs to easily tear apart the tender meat. Plate it beautifully alongside your jus, letting the flavors mingle. This hearty dish is bound to impress, making it a perfect centerpiece for gatherings or family dinners.
