Step 01

Preheat oven to 190°C (375°F). Cook jumbo pasta shells according to package instructions. Drain and allow to cool.

Step 02

In a skillet, brown ground beef over medium heat. Drain excess fat and mix in the marinara sauce. Remove from heat.

Step 03

In a bowl, combine ricotta cheese, egg, Italian seasoning, salt, and pepper. Mix well to form a creamy filling.

Step 04

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

Step 05

Top the filled shells with the beef and marinara sauce mixture. Sprinkle mozzarella and Parmesan cheese evenly over the top.

Step 06

Cover the baking dish with foil and bake in a preheated oven for 25 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly.
