Method

Step 1 – Preheat oven to 350 degrees F. Line a roasting pan with aluminum foil.

Step 2 – Using paper towels, pat lamb dry. Using a sharp knife, score the top side of the lamb by making shallow cuts all over.

Step 3– In a small bowl, combine garlic, olive oil, rosemary, thyme, Dijon, salt and pepper.

Step 4 – Place lamb, fat side up, on a rack in the prepared roasting pan. Spread garlic mixture evenly over the lamb, rubbing in thoroughly into the scored cuts.

Step 5 – Place into oven and roast until it reaches an internal temperature of 135 degrees F for medium, about 1 hour 30 minutes to 1 hour 45 minutes, or until desired doneness. Let rest 15 minutes before slicing.

Serve immediately with mini hasselback potatoes.
