Step‑by‑Step Instructions for Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This crucial step ensures that your Chicken Parmesan Casserole will bake evenly, helping to achieve that perfect golden top and melt-in-your-mouth texture. While the oven heats, gather your ingredients and greasing materials, preparing for a delightful cooking experience ahead.
Step 2: Sauté the Chicken
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once the oil shimmers, add 4 cups of shredded cooked chicken along with 1 teaspoon of garlic powder, 1 teaspoon of Italian seasoning, and salt and pepper to taste. Stir it gently, warming the chicken for 5 minutes until aromatic and heated through, ensuring a well-seasoned base for the casserole.
Step 3: Combine the Pasta and Sauce
In a large mixing bowl, combine 2 cups of cooked pasta of your choice (such as penne or rotini) and 2 cups of marinara sauce. Mix in 1 cup of grated Parmesan cheese and 1 cup of shredded mozzarella cheese, stirring until well blended. This creamy, flavorful mixture will form the hearty base of your Chicken Parmesan Casserole.
Step 4: Integrate the Chicken
Now, fold in the warmed chicken mixture from the skillet into the pasta and sauce bowl. Stir until the chicken is evenly coated with the cheesy marinara goodness, ensuring that the flavors meld together beautifully. By combining these elements, you’re preparing a comforting tapestry of textures and tastes that will delight your family.
Step 5: Transfer to Baking Dish
Pour the combined mixture into a greased 9×13-inch baking dish, spreading it evenly with a spatula. This step ensures that the ingredients are distributed nicely, allowing for even cooking and convenient serving later. Take a moment to admire the colorful layers that signal a delicious Chicken Parmesan Casserole is about to be baked.
Step 6: Top with Cheese
Sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the top of the casserole. This cheesy layer will melt and bubble, creating a tantalizing finish. With each bite, you’ll experience the rich flavor and texture that makes Chicken Parmesan Casserole a much-loved family dish.
Step 7: Bake the Casserole
Cover the baking dish with foil and place it in the preheated oven. Bake for 30 minutes. This initial covered baking allows the flavors to intermingle while keeping the casserole moist. After 30 minutes, carefully remove the foil to let the top get crispy and golden.
Step 8: Final Bake for Crispiness
Continue to bake the casserole uncovered for an additional 10 minutes, or until the top is bubbly and golden brown. Keep an eye on it during this time, as ovens can vary. You’re looking for that beautiful crust that indicates your Chicken Parmesan Casserole is ready to impress!
Step 9: Cool and Garnish
Once baked to perfection, remove the casserole from the oven and let it cool for a few minutes. This allows the flavors to settle and the casserole to firm up for easier slicing. Garnish with fresh basil or parsley to add a vibrant pop of flavor and color, enhancing the presentation of your comforting Chicken Parmesan Casserole.
Step 10: Serve and Enjoy
Slice into your beautifully baked Chicken Parmesan Casserole and serve warm. Pair it with a fresh salad or garlic bread to round out the meal. As you dig into this heartwarming dish, savor the familiar flavors that evoke memories of family gatherings and joyful dining experiences.

• Achieve Crispiness: For an extra crispy top, broil briefly at the end, but stay close to avoid burning your Chicken Parmesan Casserole.
