Step 1

Stir the first 5 ingredients in a medium bowl to blend. Stir in 2 tablespoons of the oil. Season mixture with salt and pepper and set aside.

Step 2

Lay the flank steak flat on the work surface. Sprinkle the bread crumb mixture evenly over the steak to cover the top evenly. Starting at 1 short end, roll up the steak as for a jelly roll to enclose the filling completely. Using butcher's twine, tie the steak roll to secure. Sprinkle the braciole with salt and pepper.

Step 3

Preheat the oven to 350 degrees F.

Step 4

Heat the remaining 2 tablespoons of oil in a heavy large ovenproof skillet over medium heat. Add the braciole and cook until browned on all sides, about 8 minutes. Add the wine to the pan and bring to a boil. Stir in the marinara sauce. Cover partially with foil and bake until the meat is almost tender, turning the braciole and basting with the sauce every 30 minutes. After 1 hour, uncover and continue baking until the meat is tender, about 30 minutes longer. The total cooking time should be about 1 1/2 hours.

Step 5

Remove the braciole from the sauce. Using a large sharp knife, cut the braciole crosswise and diagonally into 1/2-inch-thick slices. Transfer the slices to plates. Spoon the sauce over and serve.

Step 6

In a large casserole pot, heat oil over medium-high heat. Add onion and garlic and saute until soft and translucent, about 2 minutes. Add celery and carrot and season with salt and pepper. Saute until all the vegetables are soft, about 5 minutes. Add tomatoes, basil, and bay leaves and reduce the heat to low. Cover the pot and simmer for 1 hour or until thick. Remove bay leaves and taste for seasoning. If sauce tastes too acidic, add unsalted butter, 1 tablespoon at a time, to round out the flavor.

Step 7

Pour half the tomato sauce into the bowl of a food processor. Process until smooth. Continue with remaining tomato sauce.

Step 8

If not using all the sauce, allow it to cool completely and then pour 1 to 2 cup portions into plastic freezer bags. Freeze for up to 6 months.
