Ingredients

  • 1 rack of lamb (8 bones) approximately 1.5 lbs
  • ½ teaspoon sea salt
  • ¼ teaspoon ground black pepper

Sauce

  • 2 tablespoons dijon
  • 2 tablespoons light brown sugar
  • 2 cloves garlic minced
  • 2 tablespoons extra virgin olive oil
  • 3 tablespoons fresh rosemary & thyme chopped
  • ½ teaspoon sea salt
  • ½ teaspoon ground black pepper

Instructions

  • Set lamb out at room temperature, sprinkle with a small amount of salt and let sit for 30 minutes. 
  • Meanwhile, preheat oven to 425 degrees F. 
  • Prepare the sauce by combining the ingredients in a small bowl and stirring together. 
  • After 30 minutes, pat the lamb dry. Sprinkle with salt and pepper.
  • Heat olive oil in a large cast iron or oven safe skillet over medium high heat. 
  • Add the lamb and sear it, meat side down, for 2-3 minutes. 
  • Flip the lamb so that the bones are facing down. Spoon the sauce over the top of the meat and place the skillet in the oven.
  • Roast lamb for 15-25 minutes, until the internal temperature reaches 125 degrees F. 
  • Remove the lamb from the skillet, placing it on a cutting board and tenting with foil. Let it rest for 15 minutes before slicing. 
  • When ready to serve, cut between the bones and serve with any excess sauce from the skillet or board. 

Notes

  • Rack of Lamb: The entire rack of ribs of a lamb, includes 8 ribs. If ordering from a butcher you can ask for it to be frenched, which is the removal of meat and fat from the bones, exposing them and making a beautiful meal centerpiece. 
  • Light Brown Sugar: For a deeper flavor substitute with dark brown sugar. 
  • Dijon Mustard: choose your favorite variety- spicy, coarse ground, etc. 
  • Garlic: Use a jarred pre-minced or mince fresh garlic. You can also substitute with 1/2 teaspoon of garlic powder. 
  • Fresh Herbs: A combination of thyme and rosemary complements the lamb. You could substitute with 1 tsp of dried herbs for every 1 tbsp called for in the recipe.
  • Storage: Store any leftovers in the refrigerator in a sealed container for up to 3 days. To reheat, place in a dish or skillet with a small amount of water or broth and then cover with foil. Bake at 350 degrees F for 10 minutes or until warmed through.
  • Freezing: After cooking, allow the meat to cool to room temperature. Then wrap in a layer of plastic wrap, and a layer of foil. Place this in a freezer bag and store in the freezer for up to 3 months. Thaw in the refrigerator overnight.
