CVap Veal Shank Osso Buco

Ossobuco (pronounced os-oh-boo-koh) is a Milanese speciality of cross-cut veal shanks braised with vegetables, white wine, and broth. It is often garnished with gremolata and traditionally served with risotto alla milanese. Ossobuco or osso buco is Italian for “bone with a hole” (osso bone, buco hole), a reference to the marrow hole at the center of the cross-cut veal shank (Wikipedia).

This classic is sometimes made with pork shanks or lamb shanks. I’m a big fan of veal shanks, so I’m going the traditional route. This is a perfect dish to make overnight in the CVap® oven, chill in the morning, and then reheat for dinner service. It’s one of those dishes that benefits from that wonderful mingling of flavors under refrigeration. Both the preparation methods I’m sharing can easily be scaled for restaurant service.

Classical Veal Cuisine in a CVap Oven

For overnight cooking, use the high yield setting on the CVap Cook & Hold Oven. This feature turns off the browning elements about 40% of the way through the cooking process. Just press START. The timer begins to count down. Settings are 180 Doneness + 6 browning for six hours. After the cook cycle, the oven will enter a 150 Doneness + 0 browning hold mode. When you walk into the kitchen the next morning, it’s done.

For this post I used a same-day method. The long hold that you would have had overnight does a lot to tenderize the shank and break down the collagen and fibers of the shank. That’s a good thing. After all, who – besides your dog – wants to chew on a medium rare shank?

In this recipe the CVap oven is set for CONSTANT COOK. Press the CONSTANT COOK button so that the light under it turns illuminates. Set the Doneness to 180 + 6 Browning for three hours. During CONSTANT COOK, the browning temperature is engaged for the full roast period. It is necessary to hold for at least a few hours after the cook cycle to help tenderize the shanks. The CVap oven will still go to a 150+0 hold. 

By the way, if you are doing something like prime rib and your doneness is set below 150° F, the CVap will hold at the temperature you set with a 0 Browning. That’s how we can do a perfect rare or medium-rare prime rib overnight.

mise en place veal osso buco
  1. Preset unit to CONSTANT COOK 180/6/3:00, and allow approximately 30 minutes to preheat. Follow instructions below.
  2. In a shallow dish, combine flour, salt, and black pepper. Dredge meat in seasoned flour. In a large skillet, melt butter with oil over medium heat. Sear meat. Take the time to make sure the sides are browned. It’s no fun holding a round thing with tongs to do the sides, but it’s worth it.
  3. Remove meat from pan, and set aside.
  4. Add onion, carrots, celery, and garlic to drippings in pan. Cook and stir for about five minutes. Stir in tomato sauce, broth, wine, basil, thyme, parsley, and bay leaf. Return meat to pan. Bring to a boil and remove from the heat.
  5. Place the contents of the saucepan into a hotel pan or a roasting pan. Make sure that the braising liquid is ¾ of the way up the shanks. Add more beef broth if you need to.
  6. Place into CVap oven and press start. Make sure the timer begins counting down. Go do something else for the next five hours or so. No dipping your bread into the pan after it starts to smell wonderful in your kitchen. Nona will hit you with a wooden spoon or throw a shoe at you. If you’re not Italian, you wouldn’t understand.☺
  7. When you’re ready for service, pull the shanks out and strain the braising liquid. Shanks and strained liquid go back into the pan and into the CVap oven, and you’re done. Grab a shank and some sauce, then put it on polenta, rice, or just on a plate.

I like to take an extra step of pureeing some of the strained bits, adding that to the broth and reducing it in a saucepan on the stove. Purists will scream foul at this step as it clouds the braising liquid. But I love the extra flavor it adds. Hold the shanks in the CVap oven while you do this. Whisking in a Beurre Manié (equal parts softened butter and flour) can speed up the process of creating that coat-the-back-of-the-spoon sauce to coat the plated Osso Buco.

Polenta with roasted crimini mushrooms and parmesan is my preferred plate liner. I noticed that the shanks shrank away from the bone a lot more with this method vs. the high-yield method. It still tasted wonderful, but overnight might be the better route to enhance the plate presentation and yield.
