Stick the thermometer into the center of the roast and set it to 135°F;
Cover the pot with a lid; lower the heat and let it cook until it reaches the set temperature. It should take about 15-20 minutes. During this time, turn the piece of roast once to cook evenly on each side. Alternatively, you can cook it in the oven at 350°F for the same time. Cooking should be done with the lid on to keep the flavors in.
When done, remove the veal roast from the dutch oven and place it on a plate. Let it rest covered with aluminum foil;
Meanwhile, remove the herbs from the dutch oven, add the butter to the juice with about 1 cup of broth;

Spoon the sauce over the meat and serve the veal roast warm. If you like a more robust flavor, put the freshly cut pieces back into the dutch oven and let them soak in the sauce for a few minutes over medium heat.
