Step by Step

Bringing this casserole to life is a straightforward process that fills your kitchen with enticing aromas. Follow these simple steps:

  1. Preheat the oven to 190°C (375°F). Bring a large pot of salted water to a boil. Add the rotini pasta and cook until al dente according to package instructions (usually 8-10 minutes). Drain the pasta well and set aside.
  2. In a deep 9×13 inch (23x33cm) baking dish, combine the raw chicken pieces, spaghetti sauce, Italian seasoning, and drained diced tomatoes. Stir until all ingredients are well combined and the chicken is evenly coated with sauce.
  3. Add the cooked and drained pasta to the baking dish with the chicken mixture. Gently fold everything together until the pasta is evenly distributed throughout the sauce. Spread the shredded mozzarella cheese evenly over the top of the pasta and chicken mixture.
  4. In a medium bowl, combine the Panko bread crumbs, softened butter, grated Parmesan cheese, garlic powder, and chopped parsley. Mix these ingredients together until well combined and the mixture resembles coarse crumbs. Sprinkle this topping evenly over the layer of mozzarella cheese in the baking dish.
  5. Bake the casserole uncovered in the preheated oven for 25 to 30 minutes, or until the topping is golden brown and the chicken is fully cooked (internal temperature should reach 74°C/165°F). Let the casserole rest for 5 minutes before serving. Serve warm, garnished with additional chopped parsley if desired.

Make It Your Own

This casserole is wonderfully versatile, allowing you to add your own twist. Here are some ideas to consider:

Cook’s Notes and Secrets

To ensure your casserole turns out perfectly every time, keep these tips in mind:

  • Ensure the chicken pieces are evenly coated in the sauce for consistent flavor.
  • Let the casserole rest after baking; this helps the sauce settle and makes it easier to serve.
  • Use a meat thermometer to check the chicken’s doneness; it should reach 74°C (165°F).
  • Consider using a separate baking dish for leftovers to maintain the freshness of the original.

Easy Parmesan Chicken Casserole FAQs

  • Can I use chicken breasts instead of thighs? Yes, you can use boneless chicken breasts if you prefer, but they may cook a little faster, so check for doneness around the 25-minute mark.
  • Can I substitute the pasta for gluten-free options? Absolutely! Use gluten-free pasta varieties to accommodate dietary restrictions.
  • What side dishes pair well with this casserole? Fresh salads, garlic bread, or roasted vegetables work wonderfully alongside this comforting dish.
