Tips for success

For a slightly thicker sauce, you can remove the meat once cooked and whisk the remaining liquid in the slow cooker with a small amount of cornstarch slurry, then heat on high for an additional 10 minutes until thickened.

This adds a beautiful sheen to the sauce and helps it coat the veal more effectively when plated. Always stir gently to avoid breaking up the tender vegetables.

If you find the sauce too thin, you can also remove the lid for the final 30 minutes of cooking to allow some of the liquid to evaporate. This concentrates the flavors and intensifies the mustard profile.

Be sure to keep a close watch during this time to ensure the vegetables do not become too soft or mushy. This simple adjustment can significantly enhance the final presentation and depth of the dish.

Variations

Herb-Infused Version: Add a sprig of fresh thyme or rosemary when adding the vegetables. The woodsy notes of the herbs complement the tanginess of the mustard and add an elegant aromatic layer to the final sauce.
Creamy Mustard Finish: Stir in two tablespoons of heavy cream just before serving. This creates a luxurious, silky finish and tempers the sharpness of the mustard, resulting in a milder, more decadent sauce.

Storage and make-ahead

Fridge: Store in an airtight container for up to 3 days.
Freezer: Freeze in a freezer-safe container for up to 2 months.
Reheat: Thaw overnight in the fridge and reheat on the stovetop over low heat until steaming hot.

Allow any leftovers to cool to room temperature for no more than two hours before transferring them to an airtight container. Properly stored, the dish will maintain its quality for up to three days.

When storing, try to keep the meat submerged in the sauce to prevent it from drying out, as the mustard-based liquid acts as a protective barrier against oxidation and loss of moisture during refrigerated storage.

This dish is an excellent candidate for making ahead, as the flavors often deepen and improve after sitting for a day. Simply follow the cooking instructions, allow the dish to cool completely, and store it in the refrigerator.

When you are ready to serve, reheat it gently on the stovetop or in the oven until heated through. This makes it a perfect option for stress-free entertaining or busy work weeks.

Serving ideas

Serve the veal tendrons hot, spooning a generous amount of the mustard sauce and the cooked vegetables over each portion. The dish pairs beautifully with a simple side of mashed potatoes, roasted root vegetables, or crusty bread to soak up the rich, flavorful sauce. A light garnish of fresh herbs, such as parsley or chives, can add a bright, fresh note to the final plate.

When plating, ensure each serving receives a good portion of the vegetables to balance the richness of the meat. The mustard sauce is the highlight of the dish, so be generous when drizzling it over the veal. Because the sauce is robust, a simple side dish is best to let the flavor of the veal and mustard take center stage without overwhelming the palate with competing elements.

Frequently asked questions

Can this dish be made in an oven instead of a slow cooker?

Yes, it can be prepared in a Dutch oven. Place all ingredients in the pot, cover tightly, and bake at 300°F (150°C) for approximately 3 to 4 hours, or until the meat is fork-tender. Ensure the liquid level is sufficient to keep the meat moist during the longer cooking time.

Why is it important to let the meat rest?

Resting allows the muscle fibers to relax and the juices to redistribute throughout the meat. If sliced immediately, the juices will escape, resulting in drier, less flavorful meat. A five-minute rest is the minimum required to ensure the best texture and moisture retention for a whole cut of meat like veal tendrons.

Does the mustard sauce need additional seasoning?

The wholegrain mustard is quite flavorful and often contains salt. However, you can taste the sauce at the end of the cooking process and adjust with a pinch of kosher salt or freshly cracked black pepper if desired. Always taste before adding more salt, as the reduction of the broth can concentrate the existing sodium.

Prep 10 minCook 8 hRest 5 minTotal 8 h 15 minServes 4

Ingredients

2 lb veal tendrons
3 carrots, sliced
2 onions, sliced
1/2 cup wholegrain mustard
1 cup chicken broth

Instructions

Place the veal tendrons into the base of the slow cooker. Ensure the meat is evenly distributed to allow for uniform cooking throughout the process.
Scatter the sliced carrots and onions over the veal. Add the wholegrain mustard directly on top of the vegetables and meat. The mustard will act as the base for the sauce as it cooks.
Pour the chicken broth over the ingredients. Cover the slow cooker and cook on low for 8 hours. Once finished, ensure the veal reaches an internal temperature of at least 145°F (63°C). Let the meat rest for 5 minutes before serving.
