1Preheat your oven to 180°C (350°F).
Cook the jumbo pasta shells according to the package instructions until al dente. Drain and set aside.
In a pan, cook the chicken breast over medium heat until fully cooked. Let it cool slightly, then shred it into small pieces.
In a large bowl, combine the shredded chicken, ricotta cheese, mozzarella cheese, salt, and garlic powder. Mix well until all ingredients are evenly distributed.
Fill each cooked pasta shell with the chicken and cheese mixture.
Spread a thin layer of tomato sauce on the bottom of a baking dish.
Arrange the stuffed shells in the baking dish, then pour the remaining tomato sauce over the top.
Cover the dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until heated through and the cheese is melted.
Remove the foil and bake for an additional 5 minutes to lightly brown the top.
Serve hot and enjoy your Chicken and Cheese Stuffed Shells.
