Slow Cooker Osso Buco

The Milanese masterclass, simplified.

Why you should cook this

The Milanese masterclass made hands-off. Four veal shanks, each tied with kitchen twine so they hold their shape through the long cook, dusted in seasoned flour, browned hard in a heavy pan, then dropped into the slow cooker with soffritto, white wine, San Marzano tomatoes, beef stock, rosemary and bay. Seven hours on low. The marrow goes silky in the bone, the meat falls off the bone, and the sauce thickens into the kind of dinner that makes a Tuesday feel like a Saturday.

Tie the shanks. Without the twine they fall apart in the cooker and the marrow swims out. Sydney butchers will tie them for you if you ask, which is a courtesy older than most of us. Make the gremolata while the shanks are cooking: parsley, garlic, lemon zest, finely chopped, mixed dry. Spoon a scoop over each plate at the table. Saffron risotto or soft polenta on the side. Open a Barbera or a Nebbiolo. Eat the marrow with a small spoon, on toast, in shame, in joy.

What to drink with it

A Barbera d’Alba, a Negroni (our recipe), or a glass of Aglianico. Crusty bread.

Notes from the kitchen

Veal shank, not beef shank. Veal has the marrow and tenderness. Beef takes twice as long. Tie each shank with kitchen twine. Stops them falling apart in the slow cooker.

Two things that go wrong

Shanks falling apart in the cooker

You didn’t tie them with twine. One loop around each shank holds the meat to the bone through the long cook.

No marrow eaten

You forgot the small spoon. The marrow is the best bit. Spread on toast with salt.

Variations worth knowing

White wine and lemon

Skip the tomato. Use only white wine and stock, finish with lemon zest. Brighter, lighter.

Lamb osso buco

Replace veal with lamb shanks. Same method, same time. Earthier.

Pork osso buco

Replace veal with pork hocks. The cheap version. Same flavour profile, half the price.

Leftovers and make ahead

Two days fridge. Reheat in the sauce in a covered pan. Pull any leftover meat off the bones and toss through pasta the next day.
