The chicken quality matters here. Boneless, skinless breasts stay tender when baked—avoid pre-cut strips as they dry out. Whole milk and heavy cream create the velvety white sauce; skip low-fat versions. For cheese, block cheddar shredded at home melts better than pre-shredded. Most grocery stores carry everything needed—Kroger or Publix have reliable dairy sections.
No heavy cream? Half-and-half with an extra pat of butter works in a pinch. Swap penne for any short pasta like rigatoni or fusilli. Fresh garlic is ideal, but jarred minced garlic at half the amount saves time. The Italian seasoning can be replaced with equal parts dried basil and oregano. For extra richness, stir a spoonful of cream cheese into the sauce.
Assemble and refrigerate overnight for deeper flavor. Bakes best straight from the fridge. Leftovers keep 4-5 days refrigerated or freeze portions for 2-3 months. Reheat covered to prevent drying.

Step-by-Step Instructions for Chicken Pasta Bake White Sauce
This method ensures a creamy, comforting bake with perfectly layered flavors every time.
Step 1: Prepare the Chicken and Pasta
Cut the 1.5 lb boneless skinless chicken breasts into bite-sized pieces and season with ½ tsp salt, ½ tsp black pepper, and 1 tsp dried Italian seasoning. This ensures every piece is flavorful. I like to let it sit for 5 minutes to absorb the seasoning.
Cook the 12 oz penne pasta in salted boiling water until al dente, about 1 minute less than package instructions. Drain and set aside. Undercooking slightly prevents mushiness during baking.
Step 2: Make the Creamy White Sauce
In a saucepan, melt the 4 tbsp butter over medium heat. Add the 0.25 cup all-purpose flour and whisk constantly for 1-2 minutes until it forms a smooth roux. This base thickens the sauce without lumps.
Gradually whisk in the 2 cups whole milk and 1 cup heavy cream, ensuring no clumps remain. Stir in minced 3 cloves garlic cloves and finely diced 1 whole onion. Cook for 5-7 minutes until the sauce thickens enough to coat the back of a spoon.
Reduce heat to low and stir in 1 cup shredded cheddar cheese and ½ cup parmesan cheese until melted. Season with the remaining ½ tsp salt. The sauce should be velvety and rich.
Step 3: Combine and Layer the Bake
In a large bowl, combine the cooked penne, chicken pieces, and white sauce. Stir gently to coat everything evenly. I use a spatula to avoid breaking the pasta.
Transfer half the mixture to a greased 9×13-inch baking dish. Sprinkle 1 cup shredded cheddar cheese on top, then add the remaining pasta mixture. Finish with the remaining 1.5 cups shredded mozzarella cheese and any leftover cheddar for a golden, bubbly topping.
Step 4: Bake to Perfection
Preheat the oven to 375°F. Bake uncovered for 20-25 minutes until the cheese is melted and golden brown and the edges are bubbling. This ensures the center is hot and the top is crispy.
Let it rest for 5 minutes before serving. This allows the layers to set slightly, making it easier to serve neat portions. The result should be creamy, cheesy, and comforting in every bite.
Pro Tips For Making Chicken Pasta Bake Recipe White Sauce
- Poach the Chicken: Simmer the chicken breasts in the milk you’ll use for the sauce—it infuses flavor and keeps the meat juicy. I learned this the hard way after too many dry, stringy batches.
- Undercook the Pasta: Boil the penne for 1-2 minutes less than the package says, since it’ll finish cooking in the oven. After a few mushy casseroles, I finally started setting a timer.
- Warm Your Milk: Heat the whole milk before adding it to the roux—cold milk makes the sauce lumpy. Sounds fussy, but it actually changes the outcome.
- Thicken Before Baking: Cook the white sauce until it coats the back of a spoon, or it’ll stay watery under the cheese. My grandmother swore by this, and she was right.
Best Sauces and Condiments for These Flavors
Classic Garlic Bread
I always pair this bake with warm garlic bread to soak up every last drop of creamy sauce. Use a baguette split lengthwise, slathered with ½ cup softened butter, 3 minced garlic cloves, and 2 tbsp chopped parsley. Toast at 375°F for 8-10 minutes. 🔥
Simple Green Salad
A crisp green salad cuts through the richness beautifully. Toss 4 cups mixed greens with 2 tbsp olive oil, 1 tbsp balsamic vinegar, and ¼ tsp salt. Add cherry tomatoes and shaved parmesan for extra freshness.
Creamy Sauce Boosts
For extra depth, stir 1 tsp Dijon mustard or ½ tsp white wine vinegar into the white sauce before baking. The acidity brightens the richness. A pinch of nutmeg (about ⅛ tsp) adds warmth that pairs perfectly with the cheeses.
Spicy Kick
Add ½ tsp red pepper flakes to the sauce or sprinkle crushed black pepper on top before baking. For heat lovers, serve with hot sauce on the side—I recommend Frank’s RedHot for its tangy vinegar base. 🌶️
Fresh Herb Garnish
Just before serving, sprinkle with 2 tbsp chopped fresh parsley or basil. The fresh herbs add a pop of color and brightness. I also love a squeeze of lemon wedge over each serving to cut through the creaminess.

Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Use 1.5 lb boneless skinless thighs for juicier results. They stay tender longer during baking and add richer flavor to the dish.
How do I prevent the pasta from drying out?
Cook pasta 1 minute less than package directions and ensure the white sauce is thick and creamy. Cover with foil during the first 15 minutes of baking.
Can I make this ahead of time?
Yes! Assemble the bake, cover tightly, and refrigerate up to 24 hours before baking. Add 5-10 minutes to the baking time if going straight from the fridge.
What can I substitute for heavy cream?
Use 1 cup whole milk + ¼ cup melted butter or 1 cup half-and-half. The sauce may be slightly less rich but will still be delicious.
