Before you start
Before beginning, ensure your slow cooker is clean and placed on a stable, heat-resistant surface near an outlet. Gather all ingredients, washing and chopping the onions and carrots into uniform pieces.
If you are preparing the gremolata yourself, finely mince the parsley and garlic, and zest the lemon, keeping the mixture in a small bowl until ready to serve. Having all components measured and ready to go will make the assembly process seamless, ensuring you can quickly load the slow cooker and start the cooking process without interruption.
Ingredients at a glance (8)
- 4 pieces veal shanks
- 1 medium onion, chopped
- 2 medium carrots, chopped
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 cup dry white wine
- 1 cup beef broth
- 1/4 cup gremolata
Instructions
Assembly Phase
- Prep and LoadPlace the veal shanks into the bottom of the slow cooker. Scatter the chopped onions and carrots over the meat. Season generously with kosher salt and black pepper.Look for Ensure the shanks are arranged in a single layer for even cooking.Tip Pat the shanks dry with paper towels before seasoning to help the salt adhere better.
At the end of this phase, the veal shanks should be arranged neatly at the bottom of the slow cooker, topped with an even layer of chopped onions and carrots. The seasoning should be distributed uniformly across the meat and vegetables.
Everything is now ready for the addition of the braising liquid, which will transform these raw ingredients into a cohesive, flavorful dish as the slow cooker does its work.
Slow Braising Phase
- Add Liquids and CookPour the white wine and the beef broth over the meat and vegetables. Cover the slow cooker with its lid. Cook on low heat for 8 hours until the meat reaches 145°F (63°C) and is fork-tender. Let the meat rest at least 3 minutes before serving.Look for The liquid should partially submerge the shanks to ensure proper braising.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Avoid lifting the lid during the cooking process to maintain a consistent temperature.
During this phase, the slow cooker maintains a consistent, low temperature. You will notice the kitchen filling with a savory aroma as the wine and broth reduce slightly and the vegetables soften. The veal is slowly absorbing the flavors of the aromatics. By the end of this phase, the meat should be visibly tender and the liquid should be rich and reduced enough to coat the back of a spoon.
Finishing Phase
- Garnish and ServeRemove the veal shanks carefully from the slow cooker. Garnish each portion with fresh gremolata before plating.Look for The meat should be falling off the bone when touched with a fork.Tip Serve with the cooking juices spooned over the meat to keep it moist.
The final phase involves removing the tender veal shanks and allowing them to rest briefly. The meat should look glossy and deep in color. Once the fresh gremolata is sprinkled over the top, the dish should appear vibrant and inviting. Check that the meat is perfectly tender and that the sauce has achieved the desired consistency before serving immediately to your guests.
Common mistakes
Avoid over-crowding the slow cooker, as this can prevent the meat from cooking evenly. Ensure the shanks are arranged in a single layer at the bottom. Do not lift the lid frequently, as this releases heat and moisture, significantly extending the cooking time and potentially drying out the meat.
Finally, ensure the vegetables are chopped to a consistent size so they soften at the same rate as the meat, providing the best texture and flavor throughout the final braising liquid.
How to tell it’s done
The veal is done when it is fork-tender and pulls away easily from the central bone. The internal temperature of the meat should reach at least 145°F (63°C) to ensure it is fully cooked and safe. Using a meat thermometer is the most accurate way to verify this.
Once done, turn off the slow cooker and let the shanks rest for at least 3 minutes before serving to allow the juices to redistribute, ensuring the meat remains as tender and succulent as possible.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
