Background: what counts as lamb?
Lamb comes from sheep typically less than a year old, the USDA says. Older animals are sold as yearling mutton or mutton, which has a stronger flavor.
American lamb is raised in nearly all 50 states by more than 80,000 family farmers and ranchers, the American Lamb Board notes.
Why Roast a Leg of Lamb?
A leg is one of the easiest cuts to feed a crowd. It roasts mostly hands-off and carves into neat slices. Leftovers make great sandwiches, gyros and salads.
How long to roast a leg of lamb
At 325°F, the USDA gives these approximate times:
- Bone-in leg, 5–7 lb: 20–25 minutes per pound.
- Bone-in leg, 7–9 lb: 15–20 minutes per pound.
- Boneless rolled leg, 4–7 lb: 25–30 minutes per pound.
Use a food thermometer. Roast lamb to at least 145°F, then let it rest at least three minutes before carving. Ground lamb needs 160°F.
How to Celebrate National Roast Leg of Lamb Day
- Go classic: make small slits and stuff them with garlic slivers and rosemary before roasting.
- Try Greek-style: rub with lemon, oregano and olive oil and roast over potatoes.
- Add a sauce: serve with mint sauce, salsa verde or a yogurt-garlic sauce.
- Carve against the grain: thin slices across the muscle fibers are more tender, so turn the roast as you go.
- Plan leftovers: stuff sliced lamb into pita with cucumber, tomato and tzatziki.
- Buy local: ask a butcher or farmers’ market for American lamb.
- Bring it to room temperature briefly: take the roast out 30 minutes before cooking for more even results.
- Save the drippings: deglaze the pan with stock to make a quick gravy.
