How to store and reheat

Leftover osso bucco can be stored in the refrigerator for up to 3 days or frozen in a sealed container for up to 3 months. It reheats beautifully, making it excellent for meal prep.

To reheat, warm the shanks and sauce on the stovetop over low heat, occasionally stirring, until heated through. Avoid using high heat, as it may dry out the meat.

Easy ingredient swaps

If you can’t find veal, beef shanks work perfectly as a substitute, offering similar tenderness and flavor. For a slightly tangy twist, replace grape juice with pomegranate juice or apple cider.

Expert tips and shortcuts

Sear the shanks well before slow cooking to lock in flavor and create a deep, rich base. This step is worth the extra effort.

Use fresh lemon zest for the gremolata—it makes a noticeable difference in brightness and aroma. Dried zest won’t provide the same lift.

Layer the vegetables underneath the shanks in the slow cooker. This ensures even cooking and allows the vegetables to soak up the flavorful juices.

If short on time, chop vegetables the night before and store them in the refrigerator, so you can assemble the dish quickly in the morning.
