How to Make Holiday Leg of Lamb
Ingredients
- 2 lbs Boneless Leg of Lamb
- 12 cloves garlic (whole)
- 1 large white onion (roughly sliced)
- 4 sprigs fresh rosemary (stems attached)
- 4 sprigs fresh thyme (stems attached)
- Kosher salt and pepper to taste
- 1/2 tbsp cumin
- 1 tbsp smoked paprika
- 1 tbsp dried Italian seasoning
- 1/2 tbsp dried oregano
- 1/3 cup mayonnaise
- 2 cups baby potatoes (halved)
- 12 small carrots (whole)
- 1 1/2 cups beef stock
Helpful Notes:
- Look for lamb at your local butcher or grocery store; inquire about sourcing a boneless leg if not readily available.
- For a lighter version, use Greek yogurt instead of mayonnaise.
- Ingredients should be at room temperature for better infusion of flavors; let them sit out for about 30 minutes before starting.
Directions
- Preheat Your Oven: Begin by preheating your oven to 325°F. This low and slow cooking method ensures the lamb becomes exquisitely tender.
- Prepare Aromatic Base: In a roasting dish, layer the sliced onion and whole garlic at the bottom, creating a flavorful bed for your lamb.
- Score and Stuff the Lamb: Take the boneless leg of lamb and make a few small slits in the thicker sections. Insert whole garlic cloves and sprigs of rosemary into these slits.
- Season the Lamb: In a small bowl, combine the mayonnaise, cumin, smoked paprika, Italian seasoning, oregano, salt, and pepper. Massage this mixture thoroughly over the leg of lamb, ensuring an even coat.
- Add More Herbs: Place additional rosemary and thyme leaves gently on top of the seasoned lamb, enhancing the aroma even further.
- Pour in the Broth: Slowly add the beef broth to the roasting dish, being careful not to wash off the seasoning from the lamb.
- Cover and Bake: Tightly cover the dish with aluminum foil and place it in the preheated oven. Allow it to bake for about 3 hours, or until the meat easily pulls away from the bone with a fork.
- Add Vegetables: During the last hour of cooking, add the halved baby potatoes and whole carrots to the roasting dish. Cook until the vegetables are tender, approximately 30 to 45 minutes.

How to Serve Holiday Leg of Lamb
For the best experience, serve the holiday leg of lamb hot, alongside those beautifully tender baby potatoes and carrots. When plating, consider slicing the lamb into thick pieces for a rustic, inviting presentation. You may also garnish the dish with fresh herb sprigs or a sprinkle of sea salt for an elegant touch.
Pair this dish with a rich red wine, such as a full-bodied Cabernet Sauvignon, to enhance the flavors. Side options could include a crisp green salad, garlic bread, or creamy mashed potatoes, all complementing the lamb beautifully.
How to Store Holiday Leg of Lamb
Store leftover cold leg of lamb in an airtight container in the refrigerator for up to 4 days. To freeze, wrap portions tightly in plastic wrap and then place them in a freezer-safe container, where they can last for up to 3 months. When ready to enjoy, thaw in the fridge overnight and reheat in the oven at 325°F until warmed through, approximately 20–25 minutes.
To ensure food safety, always check for any off smells or significant changes in texture before consuming leftovers.

- Herb Varieties: Feel free to experiment with herbs such as mint or sage for different fragrance profiles.

Variations
Herb-Crusted Vegetarian Lamb

Spiced Citrus Leg of Lamb
Incorporate zest from oranges or lemons into the mayo mixture for a refreshing citrus flavor that brightens the richness of the lamb.
Garlic and Honey Glazed Lamb
Drizzle honey over the lamb during the last hour of cooking for a sweet and sticky glaze that balances savory notes.
