Chicken Parmesan Casserole Cooking Guide

Step 1: Preheat and Prepare

Start by preheating your oven to 375°F (190°C). If you haven’t cooked your pasta yet, boil it according to package instructions until al dente, then drain. Shred your cooked chicken if it’s not already shredded and set aside.

Step 2: Combine Ingredients

In a large mixing bowl, combine the cooked shredded chicken, cooked pasta, marinara sauce, mozzarella cheese, Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper. Gently fold everything together until the pasta and chicken are evenly coated in the sauce and cheese.

Step 3: Assemble the Casserole

Lightly oil your casserole dish or spray it with non-stick spray. Pour the chicken and pasta mixture into the dish and spread it out evenly. Smooth the top with a spatula for an even bake.

Step 4: Prepare the Breadcrumb Topping

In a small skillet, heat the olive oil over medium heat. Add the breadcrumbs and toast them, stirring frequently, until golden brown and crisp, about 3-4 minutes. Sprinkle the toasted breadcrumbs evenly over the casserole. This adds a fantastic crunchy topping that contrasts beautifully with the creamy layers.

Step 5: Bake to Perfection

Place the casserole in your preheated oven and bake uncovered for 20-25 minutes, or until the cheese is melted, bubbly, and the breadcrumbs are golden. If you like an extra browned top, you can broil for an additional 1-2 minutes, watching carefully to prevent burning.

Step 6: Add Fresh Basil and Serve

Once out of the oven, sprinkle the chopped fresh basil over the top for a fresh, herby finish. Let the casserole cool for 5 minutes before serving to allow it to set slightly. Grab a serving spoon and dig in!

Allergy-Friendly Swaps

• Dairy-free cheese: Use plant-based mozzarella and Parmesan alternatives to keep it dairy-free.
• Gluten-free pasta: Swap regular pasta for your favorite gluten-free variety.
• Breadcrumb substitute: Use crushed gluten-free crackers or almond meal for the topping.
• Low-sodium marinara: Choose a low-sodium sauce if you’re watching your salt intake.

Behind the Recipe

This Chicken Parmesan Casserole was born from the desire to enjoy all the delicious flavors of chicken parmesan in a simpler, less time-consuming way. Rather than breading and frying chicken cutlets, this casserole uses shredded chicken and pasta baked together with sauce and cheese, making it perfect for busy weeknights. The breadcrumb topping adds that necessary crunch to mimic the classic texture contrast of chicken parmesan. Plus, it’s versatile enough to swap in your favorite herbs or pasta shapes.

Keep-It-Fresh Plan

• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheating: Reheat in the microwave or oven until warmed through. Add a splash of marinara or water to keep it moist.
• Freeze ahead: This casserole freezes well. Prepare the casserole fully, cover tightly with foil, and freeze for up to 2 months. Thaw overnight in the fridge before baking.

Quick Questions

Can I use fresh chicken instead of pre-cooked chicken?

You can, but you’ll need to cook the chicken first before shredding it. Poaching or baking chicken breasts until fully cooked works well. Using pre-cooked chicken is just a time-saver.

What pasta works best for this casserole?

Penne or rotini are ideal because their shapes hold sauce and cheese nicely. However, you can use any short pasta you have on hand, such as ziti or rigatoni.

Can I add vegetables to this casserole?

Absolutely! Sautéed spinach, mushrooms, or bell peppers mix in beautifully with the chicken and pasta, boosting nutrition and flavor.

Is it okay to prepare this casserole ahead of time?

Yes, you can assemble the casserole a day in advance and refrigerate it until ready to bake. Just add the breadcrumb topping and bake before serving.
