Instructions
Preheat oven to 425°F.
Fill a large pot with water and bring to a boil. Add a handful of salt. Cook pasta to al dente; meaning it still has a little bite to it. Al dente pasta absorbs sauce better while it cooks and this is going into the oven.
Meanwhile, in a medium sauce pan (about 4 quarts) over medium heat, melt butter, add flour and whisk for 2 to 3 minutes to cook out the "flour-y" taste. Add milk whisk to combine. Add pesto and whisk together. Once combined add Italian cheese and ½ of Parmesan cheese. Stir with a spoon to combine. Allow to simmer until pasta is cooked.
Add chicken to the bottom of a 9-by-13-inch baking dish and pour pesto cheese sauce over top. Add pasta. Stir to combine and mix well. Smooth pasta with a spoon and pour tomato sauce over top. Sprinkle mozzarella cheese and remaining parmesan cheese on the top.
Place baking dish on a cookie sheet and bake for 6-8 minutes until cheese is melted and bubbly. Serve and enjoy!
