How Long to Cook Lamb Shanks (Bone-In) in the dutch oven
Specification: 4 bone-in shanks, seared hard, braised two-thirds submerged in stock and wine
3-Step Execution Protocol
Preheat dutch oven to 325°F (163°C). Prepare lamb shanks (bone-in) (4 bone-in shanks, seared hard, braised two-thirds submerged in stock and wine).
Cook for 2.5–3 hours. Flip at the 75-minute mark for even browning.
Meat has shrunk well up the bone and a spoon pressed to the shank parts it without effort. Confirm internal temperature reaches 195°F–205°F (falling off the bone). Rest for 15 minutes before serving.
USDA FSIS 145°F safe minimum for whole lamb cuts; 195–205°F target reflects collagen conversion in a high-connective-tissue shank.
