First time making lamb over the holidays and it turned out great. Saving the recipe for future reference.
Make lamb room temp 1-2 hours out
Use meat thermometer
In a small bowl, combine garlic, rosemary, and pepper. Add olive oil and lemon juice. Mix until all ingredients are combine
Preheat oven to 450 degrees F.
Sear the lamb roast for 15 minutes at the higher oven temperature (450 degrees F.), then turn the oven to the lower temperature (325 degrees F.) for the rest of the cooking time. Do Not Cover the roast.
Insert meat thermometer so tip is in thickest part of lamb (not resting in fat). Cook until the lamb roast reaches an internal temperature of 120 degrees F. Remove from oven, cover with aluminum foil, and let sit approximately 15 to 20 minutes.
