Preheat the oven to 375° F. Spray a 9x13 inch baking dish with nonstick spray. Set aside.
In a large pot, boil the egg noodles according to the package directions. Drain the water and set the noodles aside.

Notes
Ingredient Tips - We use frozen Grandma’s Wide Egg Noodles or homemade pasta noodles, but any noodle will work. We make our own Italian seasoning, that includes garlic and salt. Most store-bought varieties only contain basil, rosemary, oregano, and thyme. If you are using a store-bought variety, make sure to add a pinch of garlic powder and salt to the Panko along with the Italian seasoning. Time Saving Tips - Purchase a rotisserie chicken or meal prep shredded chicken (about 2 large chicken breasts equals 3 cups shredded chicken) the day before. If preparing homemade cream of chicken soup, make up to 3 days ahead of time and store in the fridge. Storage Tips - The filling can be prepared and stored in the freezer for up to 3 months. Thaw the filling overnight in the fridge and then assemble to Panko topping and top casserole before baking. The casserole may take longer to bake.
