What is osso buco?
Osso buco or ossobuco is one of the best-known Italian dishes. Always present on the menus of any serious Italian restaurant, ossobuco has a reputation for being incredibly rich and incredibly delicious but also quite challenging to make.
The parts about its being rich and delicious are perfectly true, but I disagree about having any problems with cooking this dish at home. Iโve often cooked a classic ossobuco on the stove, and I didnโt find it particularly challenging. Using a slow cooker makes the recipe even more straightforward. Just prepare a few things on the stovetop, place everything in the cooker, and let it do its magic.
So, what is ossobuco? The translation would be โbone with a hole,โ referring to cross-cut veal shanks with the bone and its marrow in the center. The pieces of veal are slowly cooked in sauce, and the marrow releases its flavor during cooking.
The dish is a specialty of Lombard cuisine, and it is usually served with another regional classic โ the risotto Milanese, made with saffron. And with gremolata, a zesty mixture of parsley and garlic, which cuts very nicely through the richness of the dish.
What cut to use for osso buco?
Ossobuco can be made with beef or veal shank, but the veal version is considered superior; the meat is tenderer and thus easier to cook, and the taste is somewhat sweet and delicate. The plus point of using beef is that beef has a more robust flavor. Iโve tried both versions over the years; I love them both.
I had veal this time. Buying veal is generally challenging; you would have to find butchers that sell it, and when you need something as special as shanks, you might even have to order it in advance.
The slices are cut from the rear or front muscle of the upper leg. The best pieces are those cut from the middle of the leg; they are larger, they have the most marrow, and the ratio of meat and connective tissue is proportional, making these cuts particularly tender and succulent.
It is considered better to use the cuts from the animal's rear legs for making ossobuco and the front leg pieces for making soups.
Recipe ingredients
- Meat: Four thick slices of veal osso buco, cross-cut slices of the shank with the bone marrow in the middle. The recipe can also be cooked with pieces cut from a shank of beef.
- Vegetables: Carrots, onion, garlic, celeriac, or celery stalks. I use celeriac because it is more common where I live, but celery stalks are just as good.
- Liquids: Beef broth or veal stock. Make sure it is either homemade or low-sodium. Regular stock with too much salt would make the dish too salty. You can also use chicken broth or stock.
- Red wine: You can substitute it with white wine; the rich flavor will be slightly different but still delicious.
- Other ingredients: All-purpose flour, olive oil, tomato paste, canned crushed tomatoes, red wine vinegar, fine sea salt or Kosher salt, and ground black pepper. You can also add two bay leaves to the pot.
- Gremolata: Garlic, fresh parsley, anchovy filets, lemon zest.
How to make osso buco in the slow cooker or crock pot?
- Prepare the meat: Dry it with a paper towel and sprinkle it with salt and pepper. Place the flour on a large plate and dredge the shanks lightly through the flour. Pat it over the sink to remove the excess flour.
- Sear: Heat the oil in a large skillet. Brown the meat on both sides. Remove from the skillet.
- While the meat browns, finely chop the onion and the garlic. Dice the carrots and celeriac or celery.
- Cook the diced veggies in the same skillet for 5-7 minutes or until softened, occasionally stirring with a wooden spoon. Add tomato paste, and mix well for 1 minute.
- Add the canned tomatoes, stock, and wine, stir well, bring to a boil, and cook for about 3 minutes. Adjust the taste with some salt and pepper.
- Pour the sauce into the pot of the slow cooker (1). Add the browned meat and cover it with the sauce (2).
- Cook on high for 4 hours or low for 6-8 hours (3). The cooking time depends on the type of slow cooker you have. Make sure you read its instructions.
- Adjust the taste with salt, pepper, and vinegar to lift the flavors. Sprinkle the dish with fresh herbs before serving if you are not making the gremolata.
- Gremolata: Make the gremolata about half an hour before serving the slow cooker ossobuco. Finely chop the parsley and the anchovies. Grate the garlic and zest the lemon. Mix everything in a small bowl.
Good to know!
The meat will fall off the bone by the end of the cooking process. It is the way itโs supposed to be. However, if you want the meat to stay on the bone, you can tie it with string. It's not my favorite task, though. I did it this time for presentation purposes, but I leave it be otherwise.
