Slow Cooker Veal Osso Buco with Tomato and Rosemary Step-by-step instructions

Before you start

Before beginning, ensure your slow cooker is placed on a stable, heat-resistant surface near an electrical outlet. Have all ingredients measured and prepared, specifically ensuring the garlic is finely minced to distribute its flavor evenly throughout the sauce.

Check that the veal shanks are at room temperature by removing them from the refrigerator about 20 minutes before cooking. Ensure you have a clean serving platter ready, as the finished veal will be very tender and require careful handling when transferring from the slow cooker.

Instructions

Assembling the base

1. 1Assemble the base
   Place the veal shanks in an even layer at the bottom of the slow cooker bowl. Scatter the sliced red onion over the meat to ensure even distribution during the long cooking process.
   Look for The veal shanks should fit comfortably in the base of your slow cooker without needing to be stacked too high, allowing for even heat circulation.
   Tip Ensure your slow cooker is clean and dry before starting to prevent any sticking during the initial stages of the braise.

At this phase, the veal shanks should be arranged in a single layer at the bottom of the slow cooker. The red onion should be distributed evenly over the meat, creating a foundation that will soften and release its sweetness as the temperature rises.

Ensure that the ingredients are not packed too tightly, as this allows for better heat circulation. The slow cooker should be ready to be covered, marking the transition to the long, slow braising period.

Adding aromatics and sauce

2. 2Add aromatics and sauce
   Add the minced garlic and the fresh rosemary sprig over the veal. Pour the crushed tomatoes over everything, ensuring the meat is mostly covered by the liquid for consistent moisture.
   Look for The tomatoes should be poured slowly to avoid splashing the sides of the slow cooker, creating a uniform layer of sauce over the aromatics and meat.
   Tip Keep the rosemary sprig whole so it can be easily removed before serving, ensuring you get the flavor without the woody stem.

The aromatics should be well-distributed, with the minced garlic nestled among the veal and the rosemary sprig placed on top. The crushed tomatoes should cover the majority of the surface area of the meat. At this point, the slow cooker should be closed with the lid, ensuring a tight seal to maintain moisture. The setup is now ready for the extended cooking phase, where the flavors will begin to meld and the veal will start to tenderize.

Slow cook and serve

3. 3Slow cook and serve
   Cover the slow cooker and cook on low for 8 hours until the veal reaches an internal temperature of 145°F (63°C). Let the meat rest for 5 minutes before serving.
   Look for The meat is done when it is fork-tender and pulls away easily from the bone, with the sauce having thickened into a rich, glossy consistency.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Check for doneness by inserting a meat thermometer into the thickest part of the veal shank to ensure it reaches the safe internal temperature.

The veal should look dark, glossy, and very tender, with the sauce having turned into a rich, reduced gravy. The aroma should be savory and fragrant with rosemary. Before serving, check the internal temperature to ensure it has reached 145°F (63°C). The meat should be handled gently during the transfer to plates, as it will be quite delicate. The final dish is ready to be served immediately, ideally while still steaming hot from the slow cooker.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the meat from cooking evenly. Another error is failing to remove the rosemary sprig, which can leave woody bits in the sauce; always ensure it is taken out before serving.

Avoid lifting the lid frequently during the cooking process, as this releases heat and steam, which significantly increases the total cooking time and can affect the final texture of the meat. Keep the lid closed until the final hour of cooking.

How to tell it’s done

The veal is considered done when it reaches an internal temperature of at least 145°F (63°C). Visually, the meat should be extremely tender and beginning to separate from the bone with minimal pressure from a fork.

The sauce should have reduced to a glossy, thick consistency that coats the back of a spoon. Always verify the temperature with a probe thermometer inserted into the center of the largest piece to ensure it is cooked through safely and thoroughly.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
