How to Make Slow-Roasted Lamb Shoulder with Garlic-Honey Mustard Glaze
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (160°C). This low temperature will allow the lamb shoulder to roast slowly, enhancing its tenderness.
Step 2: Prepare the Lamb
- Pat the lamb shoulder dry with paper towels. This step helps achieve a crispy exterior.
- In a small bowl, combine minced garlic, Dijon mustard, whole grain mustard, honey, rosemary, thyme, black pepper, and sea salt.
- Rub this mixture generously all over the lamb shoulder, ensuring an even coat.
Step 3: Roast the Lamb
- Place the seasoned lamb in a roasting pan.
- Roast in the preheated oven for approximately 4-5 hours or until it reaches an internal temperature of 195°F (90°C) for ultimate tenderness.
- Baste every hour with any juices that accumulate at the bottom of the pan to deepen flavor.
Step 4: Rest Before Serving
Once done, remove the lamb from the oven and let it rest for at least 20-30 minutes before carving. This allows juices to redistribute throughout the meat for maximum flavor.

Common Mistakes to Avoid
When preparing your Slow-Roasted Lamb Shoulder with Garlic-Honey Mustard Glaze, it’s essential to steer clear of common pitfalls.
- Skipping the marinating step: Not allowing the lamb to marinate can result in less flavor. Always let it sit with spices for at least a few hours or overnight.
- Overcooking the lamb: Cooking for too long can make the meat tough. Use a meat thermometer to check for doneness, aiming for a tender finish.
- Ignoring resting time: Cutting into the lamb immediately after cooking can cause juices to run out. Let it rest for at least 15-20 minutes before slicing.
- Not balancing flavors: A dish can taste one-dimensional if flavors aren’t balanced. Adjust honey and mustard levels to suit your palate.
- Using low-quality ingredients: Poor-quality lamb or mustards can affect overall taste. Invest in good-quality meats and condiments for the best results.
