For a roast leg of lamb, cook at 325°F (163°C) in the oven. Approximate cooking times are 20-25 minutes per pound for a 4-7 pound roast and 15-20 minutes per pound for a 7-10 pound roast. Aim for an internal temperature of 135°F (57°C) for medium-rare, 145°F (63°C) for medium, or 160°F (71°C) for well-done. Always use a meat thermometer for accuracy and allow the lamb to rest before carving.
Roast Leg of Lamb Cooking Time Calculator
Cooking a roast leg of lamb to perfection depends on various factors, including the weight of the lamb, the desired level of doneness, and the cooking method (oven, grill, or sous vide). Here’s a general guideline for roasting a leg of lamb in the oven, but please note that these times are approximate, and it’s essential to use a meat thermometer to ensure the lamb reaches the desired internal temperature for your preferred level of doneness:
Oven Roasting (at 325°F / 163°C):
| Weight of Lamb | Cooking Time | Internal Temperature for Doneness |
|---|---|---|
| 4-7 pounds | 20-25 minutes per pound | 135°F (57°C) for medium-rare, 145°F (63°C) for medium, 160°F (71°C) for well-done |
| 7-10 pounds | 15-20 minutes per pound | 135°F (57°C) for medium-rare, 145°F (63°C) for medium, 160°F (71°C) for well-done |
Keep in mind that these times are just estimates, and the internal temperature is the most important factor in determining doneness. A meat thermometer should be used to check the lamb’s temperature, and it’s a good idea to start checking it about 15-20 minutes before the estimated cooking time is up. Remove the lamb from the oven when it’s a few degrees below your desired final temperature, as it will continue to rise while resting.
Also, be sure to allow the lamb to rest for at least 15-20 minutes after cooking before carving. This allows the juices to redistribute within the meat, resulting in a more flavorful and tender roast.
Remember that individual ovens and specific cuts of lamb may require slight adjustments to the cooking time, so it’s always best to rely on a meat thermometer for precise results.
