Instructions

Step 1: Preheat oven to 400°F. In a small bowl, combine 3 tbsp olive oil, 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 1/2 tsp sea salt, 1 tsp black pepper, and 1 tsp lemon zest to form a herb paste.
Step 2: Rub the herb mixture evenly over 2 lbs trimmed lamb backstrap. Let rest at room temperature for 15 minutes.
Step 3: Place lamb on a roasting rack in a baking tray and roast for 20-25 minutes for medium-rare, or until internal temperature reaches 135°F.
Step 4: Remove lamb from oven and tent loosely with foil. Let rest for 10 minutes before slicing thinly against the grain.
Step 5: Optional: while lamb rests, pour 1/2 cup red wine into the roasting tray and simmer over medium heat for 3-4 minutes, scraping browned bits to make a quick pan sauce to serve alongside.
