Creating Beef Braciole is straightforward if you follow these simple steps:

1. Prepare the Beef: Lay the thin slices of beef on a clean surface. Use a meat mallet to pound them slightly for even tenderness.
2. Make the Filling: In a bowl, combine breadcrumbs, Parmesan cheese, parsley, minced garlic, oregano, salt, and black pepper. Mix well.
3. Fill the Beef: Take a generous amount of the filling and place it on one end of each beef slice. Roll the beef tightly around the filling.
4. Secure the Rolls: Use kitchen twine or toothpicks to secure the rolls, ensuring the filling stays inside during cooking.
5. Sear the Rolls: In a large skillet, heat olive oil over medium-high heat. Sear the beef rolls on all sides until browned, about 3-4 minutes per side.
6. Prepare the Sauce: In the same skillet, pour in the marinara sauce, scraping any browned bits from the bottom of the pan.
7. Simmer the Braciole: Carefully place the beef rolls into the sauce. Cover and simmer on low heat for about 1 hour, turning the rolls halfway through.
8. Rest the Meat: Once cooked, remove the rolls from the sauce and let them rest for about 10 minutes before slicing.
9. Slice and Serve: Cut the rolls into thick slices, showcasing the delicious filling. Drizzle some sauce over the top before serving.
