- 2 tablespoons fresh rosemary, finely chopped: Adds a piney, fragrant note that complements the lamb beautifully.
- 4 cloves garlic, minced: Brings pungent depth and warmth to the herb rub.
- 2 tablespoons olive oil: Helps bind the herbs and garlic to the meat while promoting beautiful browning.

How to Make Roast Rack of Lamb with Rosemary Recipe
Step 1: Preheat the Oven
Start by heating your oven to 450°F (230°C) to make sure it’s nice and hot when the lamb goes in. This high temperature helps sear the outside quickly, locking in juices and creating that irresistible crust.
Step 2: Prepare the Lamb
Pat the rack of lamb dry with paper towels—this is crucial for a perfect sear. Then season generously with salt and pepper on all sides to bring out the savory flavors. Don’t be shy with the seasoning here; it’s the foundation.
Step 3: Make the Herb Rub
In a small bowl, mix the finely chopped rosemary, minced garlic, and olive oil until well combined. If you want to add a little tang, stir in the optional Dijon mustard. This mixture is going to infuse the lamb with incredible aroma and flavor intensity.
Step 4: Season the Lamb
Rub the herb and garlic mixture all over the lamb rack, pressing it firmly into the meat so every bite delivers that robust herbaceous character. This step is where the magic really happens—the lamb absorbs those vibrant flavors.
Step 5: Roast the Lamb
Place the lamb on a roasting pan or baking sheet, bone-side down. Into the oven it goes for about 20-25 minutes, or until the internal temperature hits 125°F (52°C) for that perfect medium-rare. Keep a meat thermometer handy to nail the timing—nothing beats a juicy, tender cut.
Step 6: Rest the Lamb
Once roasted, remove the lamb from the oven and loosely cover it with foil. Resting for about 10 minutes is crucial as it allows the juices to redistribute, making every slice tender and moist.
Step 7: Slice and Serve
After resting, slice the rack between the bones into individual chops. Serve them right away to enjoy the full flavor and beautiful presentation of this Roast Rack of Lamb with Rosemary Recipe.
How to Serve Roast Rack of Lamb with Rosemary Recipe

Garnishes
Simple garnishes enhance without stealing the spotlight. Try sprinkling a few fresh rosemary sprigs over the sliced lamb or add a drizzle of good-quality olive oil for that glossy finish. A squeeze of lemon or a few flaky sea salt crystals can bring brightness and texture.
Side Dishes
This dish pairs wonderfully with earthy sides like roasted root vegetables, creamy mashed potatoes, or a fresh green salad with a tangy vinaigrette. The savory richness of the lamb calls for sides that either complement or cut through to keep the palate balanced and excited.
Creative Ways to Present
For a wow factor, serve the rack as a whole centerpiece at the table and slice in front of guests—it adds drama and invites interaction. Alternatively, serve individual lamb chops atop a bed of herbed couscous or alongside a colorful vegetable ratatouille to brighten the plate.
Make Ahead and Storage
Storing Leftovers
Leftover lamb is a treasure! Store any extra slices in an airtight container in the refrigerator and use within 3 days to maintain freshness and flavor.
Freezing
If you want to freeze, wrap the leftover lamb tightly in plastic wrap and aluminum foil or place in a freezer bag. Freeze for up to 3 months for best quality. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently in a low oven at 275°F (135°C) covered with foil to keep the lamb moist, or warm slices in a skillet over medium heat with a splash of broth or water. Avoid high heat to prevent toughening the meat.
FAQs
Can I use dried rosemary instead of fresh?
While fresh rosemary really shines in this recipe, you can use dried rosemary if needed—just use about one-third the amount since dried herbs are more concentrated. Consider crushing it finely to release more aroma.
How do I know when the lamb is perfectly cooked?
The most reliable way is using a meat thermometer. For medium-rare, aim for an internal temperature of 125°F (52°C) before resting. The temperature will rise slightly while resting, finishing around 130-135°F (54-57°C).
Can this recipe be made with other cuts of lamb?
This herb rub and method work best with a rack of lamb, but you can adapt it for lamb chops or a leg of lamb, adjusting cooking times accordingly to maintain tenderness and flavor.
Why is it important to rest the lamb after roasting?
Resting allows the juices to redistribute throughout the meat, which prevents them from running out when sliced. This step ensures juicy, tender lamb rather than dry or tough pieces.
Is the Dijon mustard necessary?
Not at all! Dijon mustard is optional and adds a subtle tang that complements the rosemary and garlic, but you can leave it out if you prefer a more straightforward herb flavor.
Final Thoughts
This Roast Rack of Lamb with Rosemary Recipe is the kind of dish that makes any meal feel special, combining elegance and ease in a way that invites you to savor every bite.
