Originating from Lombardy in Northern Italy, osso buco is a classic braised dish traditionally made with veal shanks, simmered until incredibly tender, and finished with a fresh gremolata.

What You’ll Need
For the Osso Buco
- Veal or Beef Shanks: 4 pieces, about 1 ¼ to 1 ½ inches thick (2-3 lbs total). Veal is traditional, but beef shanks are a fantastic, often more accessible and budget-friendly substitute.
- All-Purpose Flour: ½ cup, for dredging.
- Kosher Salt & Black Pepper: For seasoning.
- Olive Oil or Butter: 2 tablespoons for browning.
- Onion, Carrot & Celery: 1 medium of each, finely chopped (the classic soffritto).
- Garlic: 2-3 cloves, minced.
- Dry White Wine: 1 cup. A Sauvignon Blanc or Pinot Grigio works well. For an alcohol-free version, substitute with additional broth or white grape juice.
- Canned Tomatoes: One 14-15 oz can of diced or crushed tomatoes, with juices.
- Broth: ¾ – 1 cup chicken or beef broth.
- Fresh Herbs: A few sprigs of thyme and rosemary, tied together with kitchen twine.
For the Gremolata
- Fresh Flat-Leaf Parsley: ¾ cup, finely chopped.
- Lemon Zest: Zest from 1 large lemon (about 2 tablespoons).
- Garlic: 1 clove, finely grated or minced.
For Serving (Classic Pairings)
- Creamy polenta, mashed potatoes, or saffron risotto.
Step-by-Step Directions
Part 1: Sear and Build Flavor
- Prep and dredge. Pat the veal or beef shanks completely dry with paper towels. Season generously on all sides with salt and pepper. Place the flour on a plate and dredge each shank, shaking off any excess. This helps create a golden crust and thicken the sauce later. Pro Tip: For the best sear, ensure the meat is dry before it hits the pan. Drying helps achieve a deep, flavorful browning instead of steaming.
- Brown the shanks. In a large skillet or Dutch oven, heat the oil or butter over medium-high heat. Once hot, add the shanks (work in batches if needed) and sear for 4-5 minutes per side until deeply browned. Transfer the seared shanks to the insert of your slow cooker.
- Sauté the vegetables. In the same skillet, add the chopped onion, carrot, and celery. Sauté for 5-6 minutes until they begin to soften. Add the minced garlic and cook for another minute until fragrant.
- Deglaze with wine. Pour the white wine into the skillet. Use a wooden spoon to scrape up all the flavorful browned bits from the bottom of the pan. Let it simmer for 2-3 minutes to cook off the alcohol. Pour the entire contents of the skillet over the shanks in the slow cooker.
Part 2: Slow Cook to Tenderness
- Add remaining ingredients. To the slow cooker, add the canned tomatoes with their juices, the broth, and the bundle of fresh herbs. Optional Chef’s Touch: For a deeper flavor, stir in a tablespoon of tomato paste with the sautéed vegetables before deglazing.
- Cook low and slow. Cover the slow cooker and cook on the LOW setting for 6 to 8 hours. The osso buco is done when the meat is incredibly tender and practically falling off the bone.
- Finish the sauce. Carefully transfer the cooked shanks to a platter and tent with foil to keep warm. Strain the cooking liquid from the slow cooker into a saucepan. Bring to a simmer over medium heat and let it reduce for 10-15 minutes until it thickens slightly to a rich gravy consistency. Season the sauce to taste with additional salt and pepper.
Part 3: Make the Gremolata & Serve
- Prepare the gremolata. While the sauce reduces, make the gremolata. On a cutting board, finely chop the parsley. Add the lemon zest and grated garlic. Chop everything together until well combined and fragrant. This bright, zesty garnish is essential for cutting through the richness of the dish.
- Serve. Place a warm veal shank on a bed of creamy polenta or mashed potatoes. Spoon the reduced sauce over the top and finish with a generous sprinkle of the fresh gremolata.

How to Serve
Osso buco deserves classic pairings. Serve it over a bed of creamy polenta or saffron risotto (risotto alla Milanese) to soak up the incredible sauce. A side of garlic sautéed greens or a simple arugula salad provides a fresh contrast. For a truly authentic touch, use a small spoon to scoop out the rich, savory bone marrow from the center of the shank—it’s considered a delicacy.
Expert Tips for Success
- The Sear is Key: Do not skip browning the meat. This Maillard reaction is crucial for developing deep, complex flavors in the final dish.
- Make-Ahead Magic: Osso buco tastes even better the next day as the flavors have more time to meld. Prepare it fully, let it cool, and reheat gently on the stovetop.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. The dish also freezes beautifully for up to 3 months.
- Wine Pairing: Complement this rich dish with a medium-bodied Italian red like a Chianti Classico or a Barolo. A full-bodied white wine can also work well.
Common Questions
What does “osso buco” mean?
The name is Italian for “bone with a hole,” a perfect description of the cross-cut shank with the marrow-filled bone in the center.
Can I use beef instead of veal?
Absolutely. While veal is the traditional choice, beef shanks are an excellent and widely available substitute. They are just as suitable for slow cooking and will result in a similarly tender, flavorful dish.
Can I cook this on high heat in the slow cooker?
You can cook on HIGH for 4-5 hours if you’re short on time, but cooking on LOW for a longer period generally yields the most tender, fall-apart texture.
Do I have to strain the sauce?
It’s a matter of preference. Straining creates a smooth, elegant sauce. For a more rustic, hearty presentation, you can simply skim off any excess fat and serve the sauce with the softened vegetables included.
