How to Make Oven-Roasted Leg of Lamb with Garlic & Rosemary
Preheat Your Oven: Begin by preheating your oven to 425°F (220°C). A hot oven ensures that you get that delightful crust on your lamb right away.
Prepare the Marinade: In a bowl, mix minced garlic with chopped rosemary, salt, pepper, and olive oil until well combined. The aroma will make you swoon!
Season Your Lamb: Rub this aromatic mixture all over your leg of lamb generously. Don’t forget to get into all those nooks and crannies—this is where flavor happens.
Sear the Lamb: Heat a cast-iron skillet over medium-high heat and sear the lamb on all sides until golden brown—about 3-4 minutes per side. This step locks in moisture!
Roast It Up!: Transfer your seared lamb to a roasting pan. Roast in the preheated oven for about 1 hour or until it reaches an internal temperature of 135°F (57°C) for medium-rare.
Let It Rest Before Serving: Once out of the oven, let it rest for at least 15 minutes before slicing. This allows juices to redistribute, ensuring every bite is tender and juicy.

FAQ
What is the best temperature to cook an oven-roasted leg of lamb?
For optimal results, preheat your oven to 325°F (160°C). This slow roasting method ensures even cooking and helps maintain tenderness while allowing flavors to develop beautifully.
