Ingredients
The foundation of this bake is fresh, high‑quality chicken and a classic Alfredo sauce built on butter, flour, and cream. Pasta provides the perfect vehicle for the sauce, while a blend of Parmesan and mozzarella creates a bubbly, golden crust. Aromatics like garlic and onion add depth, and Italian seasoning ties everything together with herbaceous warmth.
Main Ingredients
- 4 boneless, skinless chicken breasts (about 1½ lbs)
- 12 oz penne pasta
- 2 cups heavy cream
Cheese & Sauce Components
- 1 cup freshly grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 3 tablespoons unsalted butter
- 2 tablespoons all‑purpose flour
Seasonings & Aromatics
- 3 cloves garlic, minced
- 1 small onion, finely diced
- 1 cup low‑sodium chicken broth
- 1 teaspoon Italian seasoning
- Salt and freshly ground black pepper, to taste
- 2 tablespoons chopped fresh parsley (for garnish)
Together, these ingredients create a harmonious balance: the butter‑flour roux thickens the cream into a luxurious sauce, while Parmesan adds umami and mozzarella contributes melt‑in‑your‑mouth stretch. The chicken stays juicy thanks to a quick sear, and the pasta absorbs just enough sauce to stay moist without becoming mushy. Fresh parsley at the finish adds a pop of color and a bright herbal note that lifts the entire dish.
Step-by-Step Instructions

Preparing the Chicken
Pat the chicken breasts dry, then slice each into bite‑size strips. Season both sides with salt, pepper, and half of the Italian seasoning. Let them sit for about 10 minutes; this brief rest allows the seasoning to penetrate, ensuring every bite is flavorful.
Cooking the Pasta
Bring a large pot of salted water to a rolling boil. Add the penne and cook until al dente, usually 1 minute less than the package directs. Drain, reserving ½ cup of cooking water, and set aside. The reserved water will help loosen the sauce if it becomes too thick.
Creating the Alfredo Sauce
- Build the roux. In a large skillet over medium heat, melt 3 tablespoons unsalted butter. Sprinkle 2 tablespoons all‑purpose flour over the butter and whisk continuously for 2 minutes until the mixture turns a light golden color. This cooks out the raw flour taste and forms the base for a silky sauce.
- Sauté aromatics. Add the diced onion and minced garlic to the roux. Cook, stirring frequently, for 2–3 minutes until the onion becomes translucent and the garlic is fragrant, but not browned. Over‑cooking garlic can introduce bitterness, so keep a close eye.
- Incorporate liquids. Slowly whisk in 1 cup low‑sodium chicken broth followed by 2 cups heavy cream. Continue whisking until the mixture is smooth and begins to thicken, about 4–5 minutes. If the sauce thickens too quickly, add a splash of the reserved pasta water.
- Finish the sauce. Stir in 1 cup freshly grated Parmesan, the remaining 1 teaspoon Italian seasoning, and a pinch of salt and pepper. Reduce heat to low and let the sauce simmer gently for another 2 minutes, allowing the cheese to melt fully and the flavors to meld.
Assembling the Bake
While the sauce simmers, heat a separate large skillet over medium‑high heat. Add a drizzle of olive oil and sear the seasoned chicken strips for 3–4 minutes per side, just until they develop a golden crust. They will finish cooking in the oven, so avoid over‑cooking now.
Combining & Baking
- Mix everything together. In a large mixing bowl, combine the cooked penne, seared chicken, and the Alfredo sauce. Toss until every piece is evenly coated. If the mixture appears too thick, add a little more reserved pasta water.
- Transfer to a baking dish. Lightly grease a 9‑x 13‑inch casserole dish. Spread the mixture evenly, then sprinkle 1 cup shredded mozzarella over the top for that irresistible bubbly crust.
- Bake. Preheat the oven to 375°F (190°C). Place the dish in the middle rack and bake for 20 minutes, or until the sauce bubbles around the edges and the mozzarella turns golden brown.
- Broil for extra color. Switch the oven to broil for the final 2–3 minutes, watching closely, until the cheese develops a deep, caramelized hue. Remove from the oven and let the bake rest for 5 minutes before serving.
Tips & Tricks
Perfecting the Recipe
Room‑temperature chicken: Let the strips sit out for 10–15 minutes before searing. This promotes even cooking and prevents a cold center.
Don’t overcrowd the pan: Sear chicken in batches if needed. Overcrowding releases steam, which inhibits browning and reduces flavor.
Use freshly grated cheese: Fresh Parmesan melts more smoothly than pre‑grated, preventing grainy texture in the sauce.
Reserve pasta water: The starchy water helps loosen the sauce if it thickens too quickly, ensuring a glossy finish.
Flavor Enhancements
Add a splash of dry white wine to the sauce after the roux for a subtle acidity. A pinch of crushed red‑pepper flakes introduces a gentle heat, and a final drizzle of truffle oil elevates the dish with an earthy luxury.
Common Mistakes to Avoid
Avoid boiling the cream; high heat can cause it to separate, resulting in a curdled sauce. Also, don’t bake the casserole uncovered for the entire time—covering for the first 15 minutes keeps the chicken moist before the cheese browns.
Pro Tips
Finish with butter: Swirl an extra tablespoon of cold butter into the hot sauce just before mixing. It creates a glossy sheen and richer mouthfeel.
Use a meat thermometer: Aim for an internal temperature of 165°F (74°C) for the chicken. This ensures safety without overcooking.
Pre‑toast the pasta: Toss the uncooked penne with a little olive oil and bake for 5 minutes before boiling. This adds a nutty depth that complements the creamy sauce.
Garnish at the end: Sprinkle fresh parsley and a light grind of black pepper just before serving for brightness and aroma.
Variations
Ingredient Swaps
Replace chicken with sliced turkey breast, pork tenderloin, or firm tofu for a vegetarian twist. Swap penne for fusilli, rigatoni, or even spiralized zucchini to lower carbs. For a smoky note, stir in cooked bacon bits or pancetta just before baking.
Dietary Adjustments
Use gluten‑free pasta and ensure the flour is a certified gluten‑free blend for a celiac‑friendly version. Substitute heavy cream with full‑fat coconut milk and dairy‑free cheese for a dairy‑free bake. For keto, replace flour with almond flour and use shirataki noodles instead of traditional pasta.
Serving Suggestions
Pair the bake with a crisp arugula salad dressed in lemon vinaigrette, roasted garlic bread, or a simple side of sautéed green beans. For a festive touch, serve with a glass of buttery Chardonnay or a light Pinot Grigio.
Storage Info
Leftover Storage
Allow the bake to cool to room temperature, then transfer portions to airtight containers. Refrigerate for up to 4 days. For longer keeping, freeze sealed containers for up to 3 months; wrap the dish in a layer of plastic wrap before adding a foil lid to prevent freezer burn.
Reheating Instructions
Reheat in a preheated 350°F (175°C) oven, covered with foil, for 15–20 minutes until warmed through. Remove the foil for the last 5 minutes to re‑crisp the cheese. In a microwave, add a splash of milk or broth, cover, and heat on medium for 2–3 minutes, stirring halfway.
