Sous Vide Lamb Leg Temperature Guide
A lamb leg is the holiday centerpiece — and the easiest way to ruin it is uneven heat. Sous vide cooks a whole boneless leg to exactly the doneness you want, edge to edge, then a hot roast or sear builds the crust.

Buying advice
For rosy, medium-rare roast: 131-135°F for 4-6 hours (boneless leg). For a more conventional medium: 140°F for 4-5 hours. Season generously — lamb loves garlic, rosemary, lemon zest, and salt — and seal with a little oil in the bag. After the bath, pat dry and sear all over in a hot pan, or finish in a 500°F oven for 10 minutes for a roasted crust. Rest 15 minutes before carving against the grain.
FAQ
What temperature for lamb leg?
131-135°F for rosy medium-rare; 140°F for medium. Boneless legs need 4-6 hours.
Bone-in or boneless?
Boneless is easier for even cooking and carving. Bone-in adds flavor but needs more time and careful carving.
How do I get a crust on a roast?
Sear it all over in a hot pan after the bath, or blast it in a 500°F oven for 8-10 minutes.
