- Yield
- 1 rack of lamb (about 1.5 pounds) serves 4
Ingredients
- 1 rack of lamb, frenched, about 1.5 pounds (680 g)
- 2 tablespoons Dijon mustard
- 3 tablespoons fresh parsley, finely chopped
- 2 tablespoons fresh rosemary, finely chopped
- 1 tablespoon fresh thyme leaves
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- Salt and freshly ground black pepper to taste
Instructions
- Prepare the herb crust In a small bowl, combine the Dijon mustard, parsley, rosemary, thyme, garlic, and olive oil. Mix well to form a thick paste.
- Season the lamb Pat the rack of lamb dry with paper towels. Season generously with salt and freshly ground black pepper on all sides.
- Apply the herb crust Using a brush or spoon, evenly coat the entire rack of lamb with the Dijon mustard and herb mixture, pressing lightly to adhere.
- Roast the lamb Preheat your oven to 450°F (230°C). Place the rack of lamb bone-side down on a roasting pan or baking sheet. Roast for about 20 to 25 minutes, or until a meat thermometer inserted into the thickest part reads 135°F (57°C) for medium-rare.
- Rest and serve Remove the lamb from the oven and tent loosely with aluminum foil. Let rest for 10 minutes; the temperature will rise to about 140°F (60°C). Slice between the ribs to serve.
Helpful Tips
- Use a meat thermometer to ensure safe and preferred doneness.
- Allowing the lamb to rest after roasting helps the juices redistribute for tender slices.
- Frenched racks have rib bones cleaned of meat for an elegant presentation.
- Use fresh herbs whenever possible for the best flavor.
- The USDA recommends cooking lamb to a minimum internal temperature of 145°F (63°C) for safety, but medium-rare at 135°F (57°C) is common; adjust based on preference.
Storage and Make-Ahead
Store leftover lamb in an airtight container in the refrigerator for up to 3 days.
Reheat gently in a low oven or covered skillet to preserve tenderness.
