The Essential Ingredients for Success
Creating the perfect Cheesy Chicken Pasta Casserole requires a balance of pantry staples and fresh dairy. Here is what you will need to gather for this decadent bake.
The Pasta Base
16 oz (454g) Penne Rigate: I highly recommend using ridged penne. The ridges act like tiny gutters that capture and hold onto the thick white sauce, ensuring every bite is flavorful.
The Protein
3 cups (450g) Shredded Chicken Breast: Use poached or rotisserie chicken. The key is to ensure the shreds are long and tender so they distribute evenly throughout the casserole.
The Glossy White Sauce
4 tbsp (56g) Unsalted Butter: This forms the fat base of our roux, providing a rich, velvety mouthfeel to the final sauce.
1/4 cup (30g) All-Purpose Flour: Essential for thickening the sauce to that perfect “coating” consistency.
3 cups (720ml) Whole Milk: Provides the creamy volume. For an even richer experience, you can swap 1 cup of milk for heavy cream.
1 tsp (5g) Garlic Powder & 1/2 tsp (2g) Onion Powder: These “invisible” seasonings provide the aromatic depth that makes the sauce taste professional.
The Cheese Blend & Topping
2 cups (226g) Shredded Mozzarella: Known for its superior meltability and those classic “cheese pull” strings.
1/2 cup (50g) Shredded Parmesan: This adds a salty, nutty bite and is crucial for achieving those toasted golden spots on top.
1/2 cup (60g) Fine Golden Breadcrumbs: These provide the essential crunch. Using toasted or panko breadcrumbs ensures they don’t get soggy in the oven.
1 tsp (1g) Dried Parsley Flakes: A light dusting for visual contrast and a hint of herbal freshness.

How to Make the Perfect Cheesy Chicken Pasta Casserole
Step 1: Prep the Pasta and Chicken
Preheat your oven to 375°F (190°C). Grease a white rectangular ceramic baking dish (approx. 9×13 inch) with butter or non-stick spray.
Bring a large pot of salted water to a boil. Cook the penne pasta until just al dente—usually 2 minutes less than the package directions. It will finish cooking in the oven, and you want the tubes to remain firm, not mushy.
While the pasta boils, ensure your shredded chicken is ready. If you are using fresh chicken breasts, poach them in lightly simmering water for 12-15 minutes until they reach 165°F (74°C), then shred with two forks.
Step 2: Crafting the Glossy White Sauce
In a large saucepan or Dutch oven, melt the butter over medium heat. Once bubbling, whisk in the flour to create a roux. Cook for 1-2 minutes until it smells slightly nutty, but do not let it brown.
Slowly pour in the milk (720ml) while whisking constantly. This is the secret to a smooth sauce. Continue to cook, whisking frequently, until the sauce thickens enough to coat the back of a spoon.
Stir in the garlic powder, onion powder, 1 tsp salt, and 1/2 tsp black pepper. Remove from heat and stir in 1 cup of the mozzarella until melted and glossy.
Step 3: Assembly and The Topping Layer
Combine the cooked penne, shredded chicken, and the white sauce in a large bowl. Toss until the pasta is completely submerged in the creamy liquid.
Transfer the mixture into your prepared white ceramic baking dish. Level the top with a spatula.
Now, create the signature Cheesy Chicken Pasta Casserole finish. Sprinkle the remaining 1 cup of mozzarella and the 1/2 cup of parmesan evenly over the top. Follow with a dense layer of golden breadcrumbs and a light dusting of dried parsley flakes.
Step 4: The Bake and The Blister
Place the dish in the center of the oven and bake for 20-25 minutes. You are looking for the cheese to be fully melted and bubbling.
Visual Cue: For those perfect toasted spots, turn the broiler on for the last 2-3 minutes. Watch closely! You want distinct golden-brown bubbles across the surface, matching the professional aesthetic of a high-end bistro bake.
Expert Tips for Casserole Success
- Don’t Overcook the Pasta: Always aim for “undercooked” pasta when boiling. The sauce will hydrate the noodles in the oven, preventing a soggy mess.
- Freshly Shredded Cheese: Pre-shredded cheese in bags is coated in potato starch, which can make your sauce grainy. Shred your own mozzarella and parmesan for a much smoother melt.
- Season Every Layer: Season your pasta water like the sea and ensure your white sauce is well-salted before it hits the pasta.
- Rest Before Serving: Let the casserole sit for 5-10 minutes after removing it from the oven. This allows the sauce to set slightly so it clings to the pasta rather than pooling at the bottom of the dish.

Storage, Reheating & Freezing
To Store: Keep leftovers in an airtight container in the refrigerator for up to 3-4 days. This Cheesy Chicken Pasta Casserole actually tastes incredible the next day as the flavors have more time to meld.
To Reheat: For the best results, reheat in the oven at 350°F (175°C) covered with foil to prevent the cheese from burning. If using a microwave, add a splash of milk to the bowl to loosen the sauce back to its glossy state.
To Freeze: You can freeze this dish before or after baking. If freezing before, omit the breadcrumb topping until you are ready to bake. Wrap tightly in plastic wrap and foil; it will stay fresh for up to 3 months.
What to Serve With This Dish
Because this Cheesy Chicken Pasta Casserole is quite rich, I recommend pairing it with something bright and crisp. A simple arugula salad with a lemon vinaigrette or roasted broccoli with a squeeze of lime works beautifully.
If you want to keep the “casserole night” theme going with different flavors, consider trying my Buffalo Chicken Stuffed Shells for a spicy alternative that still delivers on that cheesy goodness.
Frequently Asked Questions
Yes! Assemble the casserole (minus the breadcrumbs), cover it tightly, and refrigerate for up to 24 hours. Add the breadcrumbs just before putting it in the oven.
Yes, but I recommend using another ridged shape like rotini or large shells. These shapes are specifically designed to hold onto thick cream sauces.
Absolutely! Using a store-bought rotisserie chicken is a great time-saver. Simply shred the breast meat and follow the assembly instructions as written.
For the most visual appeal, turn your oven to the broiler setting for the final 2-3 minutes of baking. Watch it carefully to ensure the breadcrumbs don’t burn!
The secret is to cook the pasta for 2 minutes less than the ‘al dente’ package directions. It will absorb moisture from the white sauce and finish cooking perfectly in the oven.
