Directions:
Preheat the oven to 375°F (190°C). Cook the pasta shells according to the package instructions. Drain and let them cool slightly.

In a skillet over medium heat, brown the ground beef. Once fully cooked, drain any excess fat and stir in the marinara sauce. Remove from heat.

In a mixing bowl, combine the ricotta cheese, egg, Italian seasoning, salt, and pepper, stirring until smooth.

Fill each cooked pasta shell with the ricotta mixture, and place the filled shells in a baking dish.

Spoon the beef and marinara sauce mixture over the stuffed shells. Sprinkle the mozzarella and grated Parmesan cheese evenly on top.

Cover the dish with foil and bake for 25 minutes. Then, remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.

Serve hot and enjoy!
