Step-by-Step Roast Leg of Lamb
1. Preheat the oven to 375°F (190°C).
Begin by preheating your oven to ensure even cooking. This temperature is perfect for achieving a beautifully roasted leg of lamb with a crispy exterior.

Generously coat your whole leg of lamb (about 4-5 pounds) with the flavorful marinade. Let it sit at room temperature for at least 30 minutes or refrigerate overnight for deeper flavor.
4. Place the marinated lamb in a roasting pan.
Carefully position your seasoned leg of lamb in a roasting pan, ensuring it’s snug but not cramped. Insert a meat thermometer into the thickest part to monitor its doneness.

Your Roast Leg of Lamb Questions, Answered
How do I choose the best leg of lamb for roasting?
When selecting a leg of lamb, look for one that weighs between 4-5 pounds, which is perfect for feeding about four people. Choose a leg with a nice layer of fat on top; this will help keep the meat juicy and flavorful during roasting. Freshness is key—ask your butcher for the freshest cut available!
Can I use dried herbs instead of fresh in the marinade?
While fresh herbs like rosemary and thyme add vibrant flavor, you can certainly substitute dried herbs if that’s what you have on hand! Use about one-third of the amount—so for this recipe, use around 1 tablespoon of dried rosemary and 1 tablespoon of dried thyme. Just keep in mind that the flavors may not be as bright.

After enjoying your succulent roast, let any leftovers cool down to room temperature, then wrap them tightly in plastic wrap or aluminum foil.
