Ingredients
Main Ingredients
- 4 pieces veal shanks
Aromatics
- 1 medium red onion, sliced
- 2 cloves garlic, minced
- 1 sprig fresh rosemary
Sauce
- 28 oz crushed tomatoes
Why this recipe works
The slow cooker method works by maintaining a steady, low-temperature environment that allows the connective tissues in the veal shanks to break down gradually. This process is essential for achieving the signature tender texture of osso buco, which would be difficult to replicate with high-heat cooking methods.
The enclosed environment also ensures that the moisture remains within the vessel, preventing the meat from drying out while it simmers in the tomato-based sauce.
Using a slow cooker also allows the aromatics, specifically the minced garlic and rosemary, to infuse the meat thoroughly over an extended period. Because the cooking liquid is tightly contained, the flavors of the tomatoes concentrate as they reduce slightly, resulting in a robust, savory sauce.
This technique requires very little intervention, making it a highly efficient way to prepare a dish that typically demands hours of attention on a stovetop.
Notes and substitutions
When selecting veal shanks, look for pieces that are uniform in size to ensure they cook at the same rate. If you find shanks with a large amount of marrow, these are particularly prized for the richness they add to the sauce during the long braise. Always ensure the shanks are cut to a similar height so they sit evenly at the bottom of the slow cooker, which promotes uniform heat distribution and consistent cooking results.
The choice of crushed tomatoes significantly impacts the final texture of the sauce. Using a high-quality, plain crushed tomato product without added sugar or heavy seasoning allows the natural flavor of the veal and the aromatics to shine. If you prefer a smoother sauce, you can briefly blend the liquid before serving, although many enjoy the rustic texture provided by the tomatoes as they break down during the cooking process.
- veal shanks: beef shanks cut into 1.5-inch pieces work well as a direct, budget-friendly alternative that maintains the braising quality required for this slow-cooked dish.
- fresh rosemary: 1 teaspoon of dried rosemary can be used if fresh is unavailable, though it will have a slightly more concentrated and earthy flavor profile.
