Baked Chicken Pasta Recipe White Sauce: Al Dente Noodles in Velvety Parmesan Cream

There’s something deeply satisfying about a perfectly baked pasta dish with golden edges and bubbling sauce. This recipe combines tender chicken, al dente noodles, and a velvety parmesan cream that’s rich without being heavy.

I’ve refined this method over time to ensure the sauce clings beautifully to every strand of pasta while the chicken stays juicy. The baking step creates a crisp top layer that gives way to creamy perfection underneath.

The Parmesan is non-negotiable for depth of flavor—grab a wedge of Parmigiano-Reggiano from Whole Foods or a specialty grocer rather than pre-grated, which contains anti-caking agents that affect melt. The chicken should be uniform in size (1-inch pieces) to ensure even cooking. For the pasta, De Cecco or Barilla penne hold up best to baking without turning mushy. Look for heavy cream with at least 36% fat content for the velvety texture.

No heavy cream? Half-and-half plus a pat of butter works in a pinch (slightly less rich). Out of Parmesan? Pecorino Romano at a 1:1 ratio offers a sharper flavor. Fresh thyme can replace dried at three times the amount. For a lighter version, swap whole milk for 2% (but the sauce won’t be as luscious). The Dijon mustard adds subtle complexity—don’t substitute yellow mustard.

This casserole reheats beautifully—cover with foil and warm at 350°F until bubbling. Store leftovers in an airtight container for up to 4 days in the fridge or freeze for 3 months. Bake from frozen? Add 15-20 minutes to the cook time, tenting with foil to prevent over-browning. Always let it rest 10 minutes after baking for cleaner slices.

Step-by-Step Instructions for Baked Chicken Pasta in White Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear and Season the Chicken

Heat the 1 tbsp olive oil in a large skillet over medium-high heat. Add the 1.5 lb boneless skinless chicken breasts (cut into bite-sized pieces) and season with ½ tsp salt, ½ tsp black pepper, and ½ tsp dried thyme.

Cook the chicken for 5-6 minutes, stirring occasionally, until the pieces are golden brown and cooked through. The internal temperature should reach 165°F. Transfer the chicken to a plate and set aside.

Step 2: Build the Roux and Aromatics

In the same skillet, melt the 4 tbsp unsalted butter over medium heat. Add the finely diced 1 whole yellow onion and cook for 3-4 minutes until softened and translucent.

Stir in the minced 4 cloves garlic cloves and cook for 30 seconds until fragrant. Then add the 0.25 cup all-purpose flour and whisk constantly for 1-2 minutes to form a light golden roux. This creates the base for your velvety sauce.

Step 3: Create the Velvety Parmesan Cream Sauce

Gradually whisk in the 2 cups whole milk and 1 cup heavy cream, ensuring no lumps remain. Stir in the 1 tbsp Dijon mustard, 0.25 tsp nutmeg, and remaining 1 tsp salt.

Bring the mixture to a gentle simmer and cook for 3-4 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in 1.5 cups Parmesan cheese until fully melted and smooth.

Step 4: Combine and Bake to Perfection

Preheat your oven to 375°F. In a large bowl, combine the cooked 12 oz penne pasta, seared chicken, and prepared sauce. Toss until everything is evenly coated.

Transfer the mixture to a greased baking dish and bake for 15-20 minutes until the top is golden brown and bubbling at the edges. Let it rest for 5 minutes before serving to allow the sauce to set slightly.

Essential Equipment for Great baked chicken pasta recipe white sauce

Skillet Essentials

A sturdy 12-inch stainless steel skillet is my top pick for searing chicken and building the roux. I use All-Clad D3—it distributes heat evenly and the large surface area prevents overcrowding. A nonstick version works too, but avoid high heat to preserve the coating. 💡

Baking Dish Matters

For baking, a 9×13-inch ceramic or glass dish is ideal. I love my Le Creuset stoneware—it retains heat beautifully for even cooking. Avoid metal pans, which can cause the edges to brown too quickly before the center heats through.

Sauce Whisk

A balloon whisk is indispensable for creating a lump-free roux and sauce. The rounded shape fits perfectly in skillet corners. I keep a OXO Good Grips 11-inch whisk in my kitchen for this exact purpose.

Cheese Grater

Freshly grated Parmesan melts smoother than pre-shredded. A Microplane creates fine, fluffy shreds that incorporate seamlessly into the sauce. Plus, it’s easier to clean than a box grater.

Measuring Tools

Accurate measurements ensure consistent results. I use stainless steel measuring cups and spoons from Cuisinox—they nest neatly and won’t warp over time. A liquid measuring cup with clear markings is essential for the milk and cream.

Mixing Bowls

A large stainless steel mixing bowl (at least 5-quart capacity) gives you room to toss the pasta, chicken, and sauce without spills. I prefer Winco bowls—they’re lightweight but durable for daily use.
