Preheat your oven to 350 degrees Fahrenheit. This is important for ensuring even cooking throughout the dish.
Spray a 13 x 9 x 2-inch casserole dish with non-stick cooking spray and set aside. This prevents anything from sticking to the bottom.
Place 2 pounds of boneless skinless chicken breasts in the prepared pan. Ensure they are evenly spaced for even cooking.
Season the chicken with ½ teaspoon of salt and ½ teaspoon of pepper. This will infuse the chicken with flavor.
In a mixing bowl, combine 1 (10.5-ounce) can of condensed cheddar cheese soup, 1 cup of milk, 1 cup of shredded cheddar cheese, ½ teaspoon of paprika, and ½ teaspoon of granulated onion powder. Stir until everything is well combined. This mixture creates the creamy sauce that will envelop the chicken.
Pour half of the cheese mixture over the chicken, ensuring it covers the pieces evenly.
Now, sprinkle 12 ounces of defrosted frozen broccoli florets over the cheese mixture, distributing it evenly.
Pour the remaining cheese mixture over the broccoli. This creates layers of flavor that meld beautifully while baking.
In a small bowl, mix together 1 cup of crushed Ritz style crackers and 2 tablespoons of melted unsalted butter. Stir until the crackers are well coated.
Sprinkle the cracker mixture over the top of everything in the casserole dish. This will give a delightful crunch to the finished dish.
Place the casserole in the preheated oven and bake for 45 to 50 minutes, or until the chicken is cooked through and the sauce is bubbling. Check for doneness by ensuring the internal temperature of the chicken reaches 165 degrees Fahrenheit.
