Roasted Rosemary Garlic Leg of Lamb – An absolutely delicious and simple roasted leg of lamb recipe that is always a crowd pleaser at Easter, Christmas or any special occasion!


  • 1 bone-in leg of lamb (picture shows 8lb leg of lamb)
  • 23 garlic cloves, cut in thick slices
  • 1 batch Lamb Seasoning


  1. Preheat oven to 325 degrees F.
  2. Combine your Lamb Seasoning and set aside.
  3. Place leg of lamb in roasting pan with rack, fat side up.
  4. Take a small knife and cut approx. 1 inch deep slits randomly all over the lamb, large enough to fit a slice of garlic in.
  5. Slide a slice of raw garlic into each slit (you really can’t have too many, but the more you have obviously the more garlicky your lamb will be).
  6. Season all over (every nook and cranny) with the lamb seasoning.
  7. Place lamb in oven, uncovered, and cook approx. 25 minutes per pound for a medium finish*  (160 degrees internal temperature – check with internal meat thermometer).
  8. Remove from oven and let rest approximately 20 minutes before carving, lightly covered with foil.
  9. Serve with this Creamy Lamb Mint Sauce!


  • *Alternate Cooking Times: 20 mins per pound for medium-rare – 145 degree internal temp; 30 mins per pound for well done – 170 degree internal temp
  • Serving Suggestion: I highly recommend serving with some creamy mint sauce, some mint jelly or even some roasted garlic.
