Preparation
Prepping the Components
Preheat your oven to 350°F (175°C) and lightly grease or prepare your 9x13-inch baking dish
Bring a large pot of generously salted water to a boil and cook the penne pasta until it is slightly underdone (al dente, about 1 minute less than package directions); drain well and set aside
Ensure your chicken is cooked, shredded, or chopped into bite-sized pieces, ready for incorporation
Building the Sauce Base
In a medium saucepan over medium heat, melt the butter completely until it shimmers lightly
Whisk in the flour vigorously to create a smooth paste (roux); continue cooking this mixture, whisking constantly, for a full 90 seconds until it smells nutty and loses its raw flour aroma
Slowly pour in the half and half while whisking continuously and aggressively to prevent lumps from forming; increase heat slightly if necessary to bring the mixture to a gentle simmer, allowing it to thicken enough to coat the back of a spoon (about 5-7 minutes)
Finishing and Baking the Casserole
Remove the saucepan from the heat entirely. Stir in the minced fresh garlic, garlic powder, Italian seasoning, salt, and pepper, mixing until fragrant
Whisk in the freshly grated Parmesan cheese until it melts completely into the sauce, creating a smooth, velvety texture; taste and adjust seasonings now
Gently fold the cooked pasta and the chopped chicken into the sauce until everything is evenly coated, ensuring a perfect base for your pasta casserole
Transfer half of the pasta mixture into the prepared baking dish, spreading it into an even layer
Sprinkle half of the mozzarella cheese evenly over this first layer
Top with the remaining pasta mixture, then finish by scattering the remaining mozzarella cheese across the top layer
Bake in the preheated 350°F oven for 25 to 30 minutes, or until the edges are bubbling and the top is beautifully golden brown
Remove the finished pasta casserole from the oven and allow it to rest undisturbed on a wire rack for 10 minutes before slicing and serving; garnish with fresh parsley if desired
Recipe Variations
Vegetarian Delight
Substitute the chicken with 2 cups of sautéed cremini mushrooms or roasted cauliflower florets for a hearty, meatless pasta casserole
Spicy Kick
Add 1/2 teaspoon of red pepper flakes into the sauce along with the seasonings for a touch of heat
Herb Boost
For a deeper herbaceous flavor, add 1 tablespoon of fresh thyme leaves along with the fresh parsley garnish
Chef's Tips
Always use freshly grated Parmesan cheese; the texture and flavor difference is monumental in a creamy pasta casserole
When adding the half and half, adding it slowly while whisking prevents lumps far better than dumping it all in at once
Do not overcook the pasta initially; it will absorb moisture and continue to cook in the oven, leading to a perfect texture in the final pasta casserole
For an extra-rich top, mix a tablespoon of melted butter with a pinch of paprika and drizzle over the mozzarella before the final 10 minutes of baking
Storage & Conservation
Room Temperature
Store covered loosely at room temperature for no more than 2 hours
Refrigerator
Store tightly covered in an airtight container for up to 4 days
Freezer
Portion into freezer-safe containers, cover tightly with plastic wrap and foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating
Reheating
Reheat individual portions in the microwave, or warm the entire casserole in a 325°F oven covered with foil for 15-20 minutes until heated through
Common Mistakes
Overcooking the pasta before baking, which results in a mushy, disintegrated texture in the final pasta casserole
Failing to cook the flour in the butter long enough, leading to a raw, pasty taste in the sauce
Adding cheese directly to boiling liquid, causing the sauce to curdle or become grainy
Forgetting the resting period after baking, causing the casserole to slump when served immediately

Frequently Asked Questions
How can I make this pasta casserole without chicken, keeping it halal compliant? expand_more
That is an excellent question focusing on customization and dietary needs. Since we are already ensuring no prohibited meats are used, removing the chicken is simple. You can easily substitute the 2 cups of cooked chicken with 2 cups of sautéed mushrooms (cremini or shiitake work beautifully for an earthy flavor), roasted broccoli florets, or even a can of drained chickpeas added in the final assembly stage. This transforms the dish into a superb vegetarian pasta casserole while maintaining all the creamy sauce integrity. Remember, the sauce is the star here!
Why did my sauce break or become grainy when I added the cheese? expand_more
This is the most common pitfall when making any cheese sauce, including this rich pasta casserole. Graininess occurs when cheese is added to overly high heat. The proteins in the cheese contract too rapidly, forcing the fat out, resulting in a separated, oily, and grainy texture. The solution, as mentioned in my tips, is to remove the saucepan from the heat entirely before whisking in your grated Parmesan. Gentle, low heat is the friend of a smooth sauce; high heat is the enemy of a perfect pasta casserole.
Can I use a different type of pasta in this casserole? expand_more
Absolutely! While penne is structurally ideal because of its ridges and tubes, feel free to experiment. Rotini, rotelle (wagon wheels), or even farfalle (bow ties) work very well in a baked pasta casserole because they offer pockets for the sauce to cling to. If you opt for long pasta like fettuccine or spaghetti, you must cut it into manageable 2-inch pieces before boiling, or it will be difficult to serve and eat neatly from the casserole dish.
How do I get that perfectly golden-brown top crust without drying out the inside? expand_more
The secret lies in the timing and the final cheese application. First, ensure your pasta is slightly undercooked before assembly. Second, use mozzarella for the top layer, as it melts beautifully and browns evenly. For the last 5 minutes of baking, if the top isn't as golden as you desire, carefully switch your oven setting to 'Broil' for 60 to 90 seconds. Watch it like a hawk during this stage! Broiling works quickly, giving you that desirable, bubbly, toasted finish on your pasta casserole without overcooking the creamy interior.
Is this recipe suitable for make-ahead meal prepping? expand_more
Yes, this pasta casserole is an excellent candidate for meal prepping, both for baking ahead and for freezing individual portions. For baking ahead, assemble the entire casserole, cover it tightly with foil, and refrigerate for up to 24 hours. When ready to bake, let it sit on the counter for about 30 minutes to take the chill off, then add about 10 to 15 minutes to the total baking time to ensure it heats through evenly at 350°F. This makes dinner planning during busy weeks incredibly simple!
