Preheat your oven to 375°F (190°C).
Pat the boneless leg of lamb dry with paper towels and set it on a clean cutting board.
In a small bowl, mince the garlic cloves and finely chop the rosemary and thyme. Add them to the bowl along with olive oil, lemon juice, Dijon mustard, salt, and black pepper. Mix well to create a herb paste.
Rub the herb paste all over the lamb, ensuring an even coating. If the lamb is tied with kitchen twine, keep the twine intact to maintain its shape during cooking.
Place the lamb in a roasting pan with a rack, ensuring the fat side is up. Pour 1 cup of chicken or lamb stock into the bottom of the pan to keep the lamb moist and create a base for the pan sauce.
Roast the lamb in the preheated oven for approximately 1 hour and 30 minutes, or until the internal temperature reaches 130°F (54°C) for medium-rare or 140°F (60°C) for medium when checked with a meat thermometer.
Halfway through cooking, baste the lamb with the juices from the pan to enhance flavor and moisture.
Once cooked to the desired doneness, remove the lamb from the oven and cover it loosely with aluminum foil. Let it rest for 15 minutes before slicing to ensure the juices redistribute.
Slice the lamb against the grain into thin slices and serve with pan juices or your favorite side dishes, such as roasted vegetables, mashed potatoes, or a fresh salad.
