Step-by-Step Instructions
Cook the Penne
Bring a large pot of generously salted water to a boil.
Add the penne and cook according to the package directions, but remove it 1–2 minutes earlier than the recommended cooking time.
The pasta should be al dente because it will continue cooking in the oven.
Drain thoroughly and set aside.
Season the Chicken
Pat the chicken dry with paper towels.
Season both sides with paprika, Italian seasoning, garlic powder, salt, and black pepper.
Make sure the seasoning is distributed evenly over the chicken.
Sear the Chicken
Heat the olive oil and butter in a large skillet over medium-high heat.
Once hot, add the seasoned chicken in a single layer.
Cook for approximately 3–4 minutes per side, depending on thickness.
The chicken should develop a beautiful golden-brown crust and reach an internal temperature of 74°C (165°F).
Transfer the cooked chicken to a plate and set aside.
Make the Garlic Alfredo Sauce
Reduce the skillet heat to medium.
Add the minced garlic to the same skillet.
Cook for approximately 30–60 seconds, stirring frequently until fragrant.
Pour in the chicken broth and heavy cream.
Use a wooden spoon to scrape the browned bits from the bottom of the skillet.
Bring the mixture to a gentle simmer.
Add the Parmesan
Gradually stir the freshly grated Parmesan into the warm cream mixture.
Continue stirring until the cheese melts completely and the sauce becomes smooth and creamy.
Season with salt and black pepper to taste.
Do not allow the sauce to boil aggressively.
Combine the Pasta
Add the drained penne directly into the skillet.
Gently toss the pasta with the Alfredo sauce until every piece is thoroughly coated.
If the sauce seems excessively thick, add a small splash of chicken broth or reserved pasta water.
Assemble the Casserole
Preheat the oven to 190°C (375°F).
Lightly grease a 9 × 13-inch baking dish.
Transfer the creamy penne into the dish and spread it evenly.
Arrange the seared chicken pieces across the top.
Sprinkle the shredded mozzarella evenly over the entire casserole.
Bake
Place the baking dish uncovered in the preheated oven.
Bake for approximately 15 minutes, or until the mozzarella is completely melted and the pasta is hot and bubbling.
Broil the Cheese
For a beautiful golden-brown finish, switch the oven to broil.
Broil for approximately 2–3 minutes, watching the casserole carefully.
Remove it as soon as the cheese develops golden, toasted spots.
Garnish and Serve
Let the pasta rest for approximately 5 minutes.
Sprinkle freshly chopped parsley over the top.
Serve warm while the sauce is creamy and the cheese is melted.
Best Tips
Cook the pasta slightly under: Al dente pasta holds its texture much better during baking.
Use fresh Parmesan: Parmesan grated directly from a block melts more smoothly into the sauce.
Do not boil the Alfredo sauce: A gentle simmer helps maintain a smooth, creamy texture.
Brown the chicken well: The golden crust adds extra flavor to the finished dish.
Watch the broiler: Cheese can go from perfectly golden to burnt very quickly.
Rest before serving: A short rest allows the sauce to thicken slightly and makes the casserole easier to portion.
Best Ingredient Options
Chicken: Chicken breast, tenders, or boneless chicken thighs can be used.
Pasta: Penne is ideal, but rigatoni, ziti, rotini, or bow-tie pasta can also work.
Cheese: Mozzarella creates the best stretchy topping, while Parmesan gives the sauce its signature savory flavor.
Cream: Heavy cream creates the richest Alfredo sauce.
Herbs: Fresh parsley works beautifully, but basil or fresh thyme can also be added.
Recipe Variations
🧄 Extra Garlic Alfredo
Add another 1–2 cloves of minced garlic for an even stronger garlic flavor.
🥦 Chicken Broccoli Alfredo
Add 2 cups of steamed broccoli florets to the pasta before transferring it to the baking dish.
🍄 Mushroom Chicken Alfredo
Sauté 8 oz sliced mushrooms after cooking the chicken, then incorporate them into the Alfredo pasta.
🌶️ Spicy Chicken Alfredo
Add 1/2 teaspoon crushed red pepper flakes to the Alfredo sauce.
🥬 Spinach Alfredo
Stir 2 cups of fresh spinach into the hot sauce until wilted before adding the pasta.
🧀 Three-Cheese Alfredo Bake
Add shredded provolone or Monterey Jack alongside the mozzarella for an extra-cheesy casserole.
What to Serve With
🥗 Fresh Green Salad
A crisp green salad with a light vinaigrette balances the richness of the Alfredo sauce.
🥦 Roasted Broccoli
Roasted broccoli adds texture and a delicious savory flavor.
🥖 Garlic Bread
Warm garlic bread is perfect for enjoying every bit of the creamy sauce.
🥬 Steamed Green Beans
Simple steamed green beans provide a fresh vegetable side.
🍅 Tomato Salad
Fresh tomatoes, herbs, and a light dressing add brightness to the meal.
Make-Ahead Instructions
Cook the chicken and pasta, prepare the Alfredo sauce, and assemble the casserole as directed.
Cover tightly and refrigerate for up to 24 hours before baking.
When ready to cook, allow the dish to sit at room temperature briefly while the oven preheats.
Because the casserole starts cold, it may require an additional 5–10 minutes in the oven.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
Keep the pasta covered to prevent it from drying out.
Reheating
Reheat individual servings in the microwave until thoroughly hot.
For larger portions, cover the casserole with foil and warm it in a 175°C (350°F) oven.
Add a splash of milk, cream, or chicken broth if the Alfredo sauce has thickened considerably.
Freezing
For the best texture, freeze the assembled casserole before baking.
Wrap the baking dish tightly with plastic wrap followed by aluminum foil.
Freeze for up to 2–3 months.
Thaw overnight in the refrigerator before baking.
Cream-based sauces can change texture slightly after freezing, so fresh preparation gives the smoothest result.
Common Mistakes to Avoid
Overcooking the pasta: It will continue cooking during baking.
Using pre-grated Parmesan: Some varieties do not melt as smoothly as freshly grated cheese.
Boiling the cream: Keep the sauce at a gentle simmer.
Under-seasoning the chicken: Proper seasoning makes the chicken flavorful even alongside the rich sauce.
Adding cheese too early: The mozzarella should be added immediately before baking.
Over-broiling: Stay near the oven during broiling because the cheese browns quickly.

Frequently Asked Questions
Can I use chicken thighs?
Yes. Boneless, skinless chicken thighs are a flavorful alternative and remain juicy when baked.
Can I use milk instead of heavy cream?
You can, but the sauce will be considerably thinner and less rich. For classic Alfredo-style results, heavy cream works best.
Can I add vegetables?
Absolutely. Broccoli, spinach, mushrooms, peas, and asparagus all work well.
Can I use a different pasta?
Yes. Rigatoni, ziti, rotini, or another sturdy pasta can replace penne.
How do I prevent the pasta from becoming mushy?
Cook the penne 1–2 minutes less than the package instructions and avoid overbaking the casserole.
Why is my Alfredo sauce too thick?
Add a small amount of warm chicken broth, milk, cream, or reserved pasta water and stir until the desired consistency is reached.
Can I prepare this casserole ahead of time?
Yes. Assemble it, cover it, refrigerate it, and bake within 24 hours for a convenient make-ahead dinner.
