- 5 lb bone-in leg of lamb: The star of the dish, this cut is perfect for roasting and stays tender with a rich, meaty flavor.
- 2 tablespoons fresh rosemary, finely chopped: Rosemary’s piney aroma enhances the lamb’s natural taste and adds freshness.
- 4 cloves garlic, minced: Garlic infuses the herb crust with a warm, savory punch that balances the richness of the meat.
- Zest of 1 lemon: Lemon zest brings a vibrant citrus zing that lifts the entire flavor profile.
- 2 tablespoons Dijon mustard: This tangy mustard acts as a flavorful glue for the herb crust while adding a subtle kick.
- 3 tablespoons extra virgin olive oil: Olive oil keeps the lamb moist and helps the herbs form a beautiful golden crust during roasting.
- Salt and pepper to taste: Essential for seasoning and enhancing all other flavors.
How to Make Herb-Crusted Roasted Lamb Recipe
Step 1: Prepare Your Lamb
Start by removing the leg of lamb from the refrigerator and letting it sit at room temperature for about 30 minutes. This step ensures the lamb cooks evenly, allowing you to achieve that perfect medium-rare doneness.
Step 2: Make the Herb Paste
In a bowl, combine the finely chopped rosemary, minced garlic, lemon zest, salt, pepper, and Dijon mustard. Mix everything until it forms a thick, fragrant paste. This mixture is where the magic begins, packing the lamb with layers of fresh and zesty flavors.
Step 3: Coat the Lamb
Rub the extra virgin olive oil all over the leg of lamb. Then generously coat the entire surface with the herb paste, pressing it in so it sticks well. This coating creates that irresistible herb crust that seals in moisture and flavor.
Step 4: Roast to Perfection
Place the lamb on a roasting rack inside a pan and slide it into the preheated oven set to 400°F (200°C). Roast for about 1 hour, or until an internal thermometer reads 135°F (57°C) for medium-rare. This method ensures the lamb remains juicy and tender while developing a golden herb crust.
Step 5: Rest and Carve
Once out of the oven, let your lamb rest for at least 15 minutes. Resting allows the juices to redistribute, ensuring every slice is moist and flavorful before you carve it into beautiful, hearty slices.
How to Serve Herb-Crusted Roasted Lamb Recipe

Garnishes
Fresh herbs like rosemary sprigs or a sprinkling of finely chopped parsley add a lovely pop of green and a fresh aroma that complements the crust. A few lemon wedges on the side invite a final citrusy squeeze for those who love a brighter bite.
Side Dishes
This Herb-Crusted Roasted Lamb Recipe pairs wonderfully with roasted vegetables such as carrots, potatoes, and Brussels sprouts to continue the rustic vibe. Creamy mashed potatoes or a fluffy couscous salad add texture contrasts, while a fresh green salad can lighten up the plate beautifully.
Creative Ways to Present
For a stunning presentation, arrange thick slices of lamb on a large platter and drizzle with pan juices or a simple red wine reduction. Scatter some toasted pine nuts or pomegranate seeds on top for unexpected texture and a splash of color that will impress your guests instantly.
Make Ahead and Storage
Storing Leftovers
Cool any leftover lamb within two hours and store it in an airtight container in the refrigerator. Properly stored, your Herb-Crusted Roasted Lamb Recipe leftovers will stay delicious for up to 3 days, making for convenient next-day meals.
Freezing
If you want to keep the lamb longer, slice it and wrap it tightly in plastic wrap and foil, or place it in a freezer-safe container. Frozen lamb will maintain the best quality for up to 2 months. Just be sure to thaw it slowly in the refrigerator before reheating.
Reheating
Reheat leftover lamb gently in a warm oven at 300°F (150°C), covered with foil to avoid drying out. Alternatively, warming slices in a pan with a splash of broth keeps the meat tender and moist without sacrificing the herb-infused flavor.
FAQs
Can I use other herbs besides rosemary in this Herb-Crusted Roasted Lamb Recipe?
Absolutely! While rosemary is classic, thyme, oregano, and parsley also work beautifully and can add different flavor dimensions to your herb crust.
How do I know when the lamb is perfectly cooked?
The best way is to use a meat thermometer. For medium-rare, aim for an internal temperature of 135°F (57°C). Remember to let it rest, as the temperature will rise slightly after taking it out of the oven.
Is it necessary to let the lamb come to room temperature before roasting?
Yes, allowing the lamb to sit at room temperature helps it cook more evenly, preventing the outside from overcooking while the inside reaches the right temperature.
Can I prepare the herb paste in advance?
Definitely! You can mix the herb paste and even coat the lamb a few hours ahead or overnight in the fridge, which can actually deepen the flavors.
What should I serve with this Herb-Crusted Roasted Lamb Recipe for a complete meal?
Roasted root vegetables, creamy mashed potatoes, or a vibrant grain salad all make excellent accompaniments, balancing richness with fresh or hearty textures.
