Ingredients
Scale
Lamb
- 3 pounds boneless leg of lamb (or 5–6 pounds bone-in leg of lamb)
- 4 cloves garlic, minced
- 1 tablespoon olive oil
- 2 tablespoons chopped fresh rosemary
- 1 tablespoon chopped fresh thyme leaves
- 1 tablespoon Dijon mustard
- 1 tablespoon kosher salt
- 2 teaspoons ground black pepper
Potatoes
- 2–3 pounds small potatoes
- 2 tablespoons olive oil
- Salt and pepper to taste
Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C) to prepare for roasting the lamb and potatoes.
- Prepare the Herb Rub: In a bowl, combine minced garlic, olive oil, chopped fresh rosemary, thyme, Dijon mustard, kosher salt, and ground black pepper. Mix well to form a fragrant herb paste.
- Rub the Lamb: Generously rub the garlic and herb mixture all over the surface of the leg of lamb, ensuring it is evenly coated for maximum flavor.
- Prepare the Potatoes: Drizzle the small potatoes with olive oil, season with salt and pepper, and place them in the bottom of a casserole dish or roasting pan.
- Roast the Lamb and Potatoes: Place the leg of lamb on top of the potatoes in the roasting pan. Roast in the preheated oven for 1 ½ to 2 hours, or until a meat thermometer inserted into the center of the lamb reads 130-135°F for medium-rare doneness. If using bone-in lamb, roasting time may be longer.
- Rest the Lamb: Remove the lamb from the oven and transfer it to a cutting board. Let it rest for 15 minutes to allow the juices to redistribute before slicing and serving.
Notes
- Use a digital meat thermometer to ensure accurate cooking temperature for perfect medium-rare lamb.
- For a more well-done roast, cook to a higher internal temperature as desired.
- Bone-in leg of lamb will require a longer roasting time; adjust accordingly.
- You can substitute rosemary and thyme with dried herbs if fresh are not available, adjusting quantities to 1 teaspoon each.
- Letting the lamb rest is essential to keep it juicy and tender.
- Potatoes roasted beneath the lamb absorb delicious meat juices for enhanced flavor.
