Step 1

Preheat oven to 350 degrees F. Lightly grease a 13x9-inch baking dish or large casserole dish with butter or nonstick spray.

Step 2

Bring a large pot of water to a boil. Cook pasta for 3/4 of the time according to package directions. Drain well.

Step 3

Meanwhile, place olive oil in large skillet over medium-high heat. Add chicken and cook for about 3-5 minutes or until cooked through, stirring occasionally.

Step 4

In a large bowl combine half of tomato sauce, ricotta cheese, 1/2 cup mozzarella cheese, Parmesan cheese, and Italian seasoning until well combined. Stir in cooked penne and chicken. Spoon evenly into prepared baking dish.

Step 5

Spoon remaining tomato sauce evenly on top of pasta, then sprinkle remaining mozzarella cheese on top. Sprinkle bread crumbs evenly over cheese.

Step 6

Bake pasta at 350 degrees F for about 20-30 minutes or until bubbly. If it starts to brown too quickly, cover loosely with aluminum foil and continue baking. Cool slightly before serving.
