To Roast a Leg of Lamb

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

Preheat the oven to 350°F (175°C).
Season the leg of lamb with salt and pepper.
Place the lamb in the oven, starting at a distance from the heat.

Roast and serve

Roast a 5-pound leg for 1 hour and 15 minutes, or a 6-pound leg for 1 hour and 30 minutes.
Baste the lamb with the fat and gravy that collects in the pan.
Serve with mint and cucumber sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Leg of lamb: Is the main meat, providing the substance and flavor of the roast.
Fat from the lamb: Moistens the surface during roasting and carries flavor, helping it brown and stay juicy.

The step that matters

Baste the lamb with the fat and gravy that collects in the pan. Spooning the rendered fat and pan juices over the meat keeps the surface moist and helps it brown evenly, so the outside does not dry out during the long roast.

Swap the cucumber
