Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Using a sharp knife, score the fat cap of the 2 pounds Frenched rack of lamb in a diamond pattern, making shallow cuts about 1/2 inch apart.
  2. Step 2: In a small bowl, mix 4 minced garlic cloves, 2 tbsp chopped fresh rosemary, 1 tbsp fresh thyme leaves, 3 tbsp olive oil, 1 1/2 tsp salt, and 1 tsp black pepper to form an herb paste.
  3. Step 3: Rub the herb paste evenly over the entire rack of lamb, pressing into the scored fat.
  4. Step 4: Heat a large ovenproof skillet over medium-high heat. Sear the rack fat-side down for 3 minutes until golden and crispy.
  5. Step 5: Flip the rack, brush all over with 2 tbsp Dijon mustard, then transfer the skillet to the oven.
  6. Step 6: Roast for 15-20 minutes for medium-rare doneness (internal temperature 135°F), or longer for desired doneness.
  7. Step 7: Remove from oven, tent with foil and rest for 10 minutes before slicing between the ribs to serve.
