Directions

1
Preheat the oven to 400F (200C).

In a small bowl, whisk together the Dijon mustard, chopped garlic, fresh rosemary, fresh thyme, soy sauce, white wine, and olive oil to create a smooth marinade.
3
Pat the leg of lamb dry with paper towels and place it in a large roasting pan.

Note

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.

Variations: For a richer flavor, add a cup of beef broth to the roasting pan before covering with foil for the first hour of cooking.

Tip: Use a meat thermometer to ensure perfect doneness. Remove the lamb from the oven when it is 5-10 degrees below your desired final temperature, as it will continue to cook while resting.

Ingredient Substitution: If fresh herbs are unavailable, use 1 teaspoon of dried rosemary and 1/2 teaspoon of dried thyme, added at the beginning of the rub.
