Why You’ll Love This Creamy Garlic Parmesan Chicken Pasta Bake
This recipe combines pasta, chicken, and a homemade cream sauce in one filling casserole.
The chicken is seasoned and cooked separately first, which helps it stay flavorful instead of tasting bland inside the pasta.
Freshly grated Parmesan gives the sauce a deep savory flavor, while mozzarella creates a stretchy, golden topping.
The pasta is cooked just shy of al dente so it finishes perfectly in the oven without becoming mushy.
It is also easy to customize with spinach, mushrooms, broccoli, bacon, or sun-dried tomatoes.

How to Make Creamy Garlic Parmesan Chicken Pasta Bake
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
2. Prepare the Chicken
Pat the chicken dry with paper towels.
Cut into approximately 1-inch bite-size pieces.
3. Season the Chicken
Place the chicken in a bowl.
Add salt, black pepper, garlic powder, onion powder, smoked paprika, and Italian seasoning.
Toss until evenly coated.
4. Heat the Skillet
Place a large skillet over medium-high heat.
Add the olive oil.
5. Cook the Chicken
Add the chicken in a single layer.
Cook for approximately 6–8 minutes, stirring occasionally, until lightly browned and cooked through.
Chicken should reach 165°F (74°C).
6. Remove the Chicken
Transfer the chicken to a plate.
Set aside.
7. Cook the Pasta
Bring a large pot of salted water to a boil.
Add the pasta.
Cook approximately 2 minutes less than the package directions.
The pasta should still be slightly firm because it will continue cooking in the oven.
8. Reserve Pasta Water
Before draining, reserve approximately ½ cup pasta water.
Drain the pasta.
Do not rinse.
9. Melt the Butter
Return the skillet to medium-low heat.
Add the butter.
10. Add Garlic
Stir in the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
Do not let the garlic burn.
11. Add Flour
Sprinkle in the flour.
Whisk continuously for approximately 1 minute.
This helps create the base for the cream sauce.
12. Add Chicken Broth
Slowly pour in the chicken broth while whisking constantly.
Continue whisking until smooth.
13. Add Heavy Cream
Pour in the heavy cream.
Stir until evenly combined.
14. Add Seasonings
Add:
- Dijon mustard
- Italian seasoning
- Garlic powder
- Onion powder
- Black pepper
- Red pepper flakes, if using
15. Simmer
Cook over medium-low heat for approximately 3–5 minutes, stirring frequently.
The sauce should begin to thicken.
16. Add Parmesan
Reduce the heat to low.
Add the Parmesan gradually, stirring until smooth and melted.
Avoid boiling aggressively once the cheese is added.
17. Adjust the Sauce
If the sauce becomes too thick, add reserved pasta water 1–2 tablespoons at a time.
The sauce should be creamy and slightly loose because the pasta will absorb more moisture while baking.
18. Add Optional Vegetables
If using spinach, stir it into the sauce now and cook until wilted.
Broccoli, mushrooms, or sun-dried tomatoes can also be added at this stage.
19. Return the Chicken
Add the cooked chicken back to the skillet.
Stir to coat it with the sauce.
20. Add the Pasta
Add the drained pasta.
Gently toss until everything is evenly coated.
21. Add Mozzarella
Stir in approximately 1 cup mozzarella.
Mix until distributed throughout the pasta.
22. Transfer to the Baking Dish
Pour the pasta mixture into the prepared baking dish.
Spread into an even layer.
23. Add More Mozzarella
Sprinkle the remaining mozzarella evenly over the top.
24. Add Parmesan
Finish with the remaining Parmesan.
25. Cover
Cover loosely with foil.
26. Bake Covered
Bake for approximately 15 minutes.
27. Uncover
Remove the foil.
28. Continue Baking
Bake for another 10–15 minutes.
The sauce should be bubbling and the cheese fully melted.
29. Broil for Extra Browning
For a deeper golden top, broil for approximately 1–2 minutes.
Watch carefully.
30. Rest
Remove the casserole from the oven.
Let it rest for approximately 5–10 minutes.
The sauce will thicken slightly as it rests.
31. Garnish
Finish with fresh parsley, basil, extra Parmesan, cracked black pepper, and red pepper flakes if desired.
32. Serve
Serve hot while the sauce is creamy and the cheese is melted.
