Ingredients
- 4 cups Cooked rotisserie chicken, shredded
- 2 cups Marinara sauce (use your favorite brand or homemade)
- 2 cups Cooked pasta (penne or rotini work best)
- 1 cup Shredded mozzarella cheese
- 1 cup Grated Parmesan cheese
- 1 tsp Garlic powder
- 1 tsp Dried oregano
- 1 tsp Italian seasoning
- Salt and black pepper, to taste
- Fresh basil, for garnish (optional)
Instructions
- Cook the Pasta: Bring a large pot of salted water to a boil and cook the pasta until just al dente according to the package instructions. Be careful not to overcook it since the pasta will continue softening while baking in the casserole. Drain well and set aside while preparing the sauce and chicken mixture.
- Prepare the Chicken Mixture: Heat olive oil in a large skillet over medium heat. Add the minced garlic and sauté briefly until fragrant, then stir in the cooked chicken, marinara sauce, salt, black pepper, and Italian seasoning. Let the mixture simmer for a few minutes so the chicken absorbs the rich tomato sauce and savory seasoning. Personally, I love using rotisserie chicken because it adds extra flavor while making this easy baked chicken parmesan casserole come together much faster on busy evenings.
- Combine the Pasta and Sauce: Add the cooked pasta into the skillet with the chicken and marinara mixture. Stir everything together until the pasta is evenly coated in the rich sauce and cheesy comfort food flavor starts coming together beautifully. The sauce should coat the pasta well without becoming overly soupy or dry.
- Layer the Casserole: Lightly grease a casserole dish, then spread half of the pasta mixture evenly into the bottom. Sprinkle mozzarella and parmesan cheese over the layer before adding the remaining pasta mixture on top. This layering method helps create rich cheesy pockets throughout the casserole instead of keeping all the cheese only on top.
- Add the Topping: Top the casserole generously with Italian breadcrumbs, extra parmesan cheese, and more mozzarella. As the casserole bakes, the topping becomes golden and slightly crispy while the cheese melts into bubbling creamy layers underneath. Personally, I think the crispy breadcrumb topping is what truly gives this casserole that classic chicken parmesan comfort food texture.
- Bake Until Bubbly: Place the casserole into the oven and bake until hot, bubbly, and golden brown on top. The cheese should be fully melted while the edges become slightly crisp and caramelized with rich savory flavor. The smell of bubbling marinara sauce, garlic, parmesan, and melted mozzarella honestly makes the kitchen feel incredibly cozy during this step.
- Garnish and Serve: Remove the casserole from the oven and allow it to rest for a few minutes before serving. Top with fresh basil or parsley for extra freshness and color, then serve hot while the cheese is still perfectly melted and creamy.
