Stuffed Flank Steak in the Oven

1. Place flank steak in the freezer for 20 minutes.

2. Meanwhile, heat 1 tablespoon olive oil in a skillet. Add mushrooms, celery, sun-dried tomatoes, and garlic; saute until softened, about 5 minutes. Remove from the heat and place in a large bowl.

3. Pat roasted red peppers dry. Chop and add to the vegetable mixture. Add bread crumbs, parsley, 2 tablespoons olive oil, capers, salt, pepper flakes, and black pepper. Mix to combine.

4. Preheat the oven to 425 degrees F (220 degrees C).

5. Remove steak from the freezer and season with salt and pepper. Turn the long side of the steak towards you and place on a flat work surface. Slice horizontally through the middle to within 1/2 inch of the opposite edge, being careful not to cut all the way through to the other side. Open the 2 sides and spread them out like an open book.

6. Leaving a 1-inch border around the edges, layer prosciutto and provolone cheese over the entire steak. Top with bread crumb mixture, patting down to adhere. Roll steak up tightly starting at the small end. Use kitchen twine to tie steak in 1-inch increments taking care to tie tightly at both ends. Season with more salt and pepper and brush with remaining 2 tablespoons olive oil. Place steak carefully on a broiler pan.

7. Bake in the preheated oven until an instant-read thermometer inserted into the center reads 145 degrees F (63 degrees C) for medium-rare, 160 degrees F (71 degrees C) for medium, or 170 degrees F (77 degrees C) for well done, 35 to 40 minutes. Turn on the broiler and broil for an additional 10 minutes.

8. Remove from the oven and let stand for 10 minutes before slicing and serving.

Cook's Note:

You can use deli ham for prosciutto, if preferred.
