How to Make Slow-Roasted Rosemary Lamb Shoulder

Prepare the lamb: Pat the lamb shoulder dry with paper towels and score the fat in a crosshatch pattern. This allows the seasoning to penetrate better and creates a beautiful crust.
Make the rub: In a bowl, combine chopped fresh rosemary, minced garlic, lemon zest, olive oil, salt, and cracked black pepper. This aromatic mixture will deeply infuse the lamb with flavor.
Season the meat: Generously rub the mixture all over the lamb, ensuring it’s pressed into the scored fat for maximum impact. Every nook and cranny deserves the flavor!
Marinate (optional): If you have time, refrigerate the seasoned lamb for at least 2 hours or overnight. This step enhances the flavors, making it even more delicious.
Prepare for roasting: Place the lamb in a roasting dish, then pour in the white wine or broth around it—be careful not to pour directly over the meat. This will create a moist roasting environment.
Cover and roast: Tightly cover the dish with foil and roast in a preheated oven at 300°F (150°C) for 4 to 4.5 hours, or until it’s fork-tender and falling apart.
Crisp the top: After initial roasting, uncover and increase the oven temperature to 400°F (200°C) for 20–30 minutes. This step will give your lamb a delightful crispy top.
Rest before serving: Once out of the oven, tent the lamb with foil and let it rest for at least 20 minutes. This allows the juices to redistribute, ensuring each bite is moist and flavorful.

Optional: Serve with fresh herbs for an added touch of color and flavor.

Slow-Roasted Rosemary Lamb Shoulder Recipe FAQs

What kind of lamb shoulder should I choose for this recipe?
When selecting a lamb shoulder, I recommend going for the bone-in variety. This cut not only provides rich flavor but also keeps the meat tender during the slow-roasting process. Look for a lamb shoulder with ample marbling, as this will melt during cooking and enhance the overall taste.

How should I store leftover Slow-Roasted Rosemary Lamb Shoulder?
To keep your scrumptious leftovers, store the lamb in an airtight container in the refrigerator for up to 3 days. To maintain its succulent quality, try to reheat it gently in the oven with a splash of broth, preventing it from drying out.

Can I freeze Slow-Roasted Rosemary Lamb Shoulder?
Absolutely! For freezing, wrap the lamb portions tightly in plastic wrap, then in aluminum foil, or place them in a freezer-safe container. This dish freezes well and can last up to 3 months. When you’re ready to enjoy it again, thaw in the fridge overnight before reheating.

What should I do if my lamb isn’t tender after roasting?
If you find your lamb shoulder isn’t fork-tender, it may need more roasting time. Continue cooking it covered until it reaches that desired tenderness, checking periodically. Also, ensure that you’re roasting at the right temperature, as variations in ovens can affect cooking times.

Are there any dietary considerations I should keep in mind?
Yes, when preparing this Slow-Roasted Rosemary Lamb Shoulder, consider the dietary needs of your guests. Lamb is rich in protein and iron, but if you have someone with specific allergies or dietary restrictions, you can easily tailor the recipe. For instance, substitute the white wine with low-sodium broth for a non-alcoholic option. Always be sure to check for any additional allergies such as garlic or specific herbs.
