Preheat oven to 325 degrees Fahrenheit.

Place vegetables in a large baking dish and set aside.

In a small bowl, add zests, salt, and pepper and mix together. Rub all over the meat.

In a pan, on a medium-high heat, heat oil. Sear the brisket on both sides till a nice crust forms.

Place meat on top of vegetables in the baking dish. Pour wine over everything.

Cover the pan tightly and cook for three hours.

Remove from oven and cool slightly.

Take most of the vegetables (leaving some for garnish) and the liquid and blend with an immersion blender to make a sauce.

To plate, take a large platter and add the sauce and place the meat, sliced, on top. Garnish with remaining vegetables.
