Ingredients
For this bake I rely on fresh, high‑quality ingredients that each play a distinct role. The chicken provides lean protein and a meaty backbone, while the pasta shells act as little bowls for the sauce. A classic Alfredo base—made from butter, cream, and cheese—creates richness, and a touch of broth keeps everything moist. Seasonings like garlic, Italian herbs, and pepper lift the dish, and the final cheese topping adds a golden finish that’s both visual and flavorful.
Main Ingredients
- 2 large boneless, skinless chicken breasts, cubed
- 12 oz (about 3 cups) medium pasta shells
Alfredo Sauce Components
- 3 tablespoons unsalted butter
- 3 tablespoons all‑purpose flour
- 1 cup low‑sodium chicken broth
- 1 cup heavy cream
- 2 cloves garlic, minced
- ½ cup freshly grated Parmesan cheese
Cheese & Seasonings
- 1 cup shredded mozzarella cheese
- 1 teaspoon Italian seasoning
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- 2 tablespoons chopped fresh parsley (optional, for garnish)
These ingredients work together to create a balanced dish. The butter‑flour roux thickens the sauce, while the broth and cream add depth and silkiness. Parmesan contributes a salty umami kick, and mozzarella delivers melt‑in‑your‑mouth stretch. Seasonings infuse the chicken and sauce with aromatic notes, and the fresh parsley brightens the final presentation, making every forkful inviting.
Step-by-Step Instructions
Preparing the Chicken
Start by patting the cubed chicken dry with paper towels—dry meat browns better. Toss the pieces with a pinch of salt, pepper, and the Italian seasoning. Heat 2 tablespoons olive oil in a large skillet over medium‑high heat until shimmering, then add the chicken. Sear for 4‑5 minutes, turning once, until each piece is golden and the interior is just cooked through. Transfer to a plate; the sear locks in juices that later keep the bake moist.
Cooking the Pasta Shells
While the chicken rests, bring a large pot of salted water to a rolling boil. Add the 12 oz pasta shells and cook for 7‑8 minutes, or until just al dente—slightly firm because they’ll continue cooking in the oven. Drain, drizzle with a little olive oil to prevent sticking, and set aside.
Making the Alfredo Sauce
- Build the roux. In the same skillet used for the chicken, melt 3 tablespoons butter over medium heat. Sprinkle 3 tablespoons flour over the melted butter, whisking constantly for 1‑2 minutes until the mixture turns a light golden color. This eliminates raw flour taste and creates a thickening base.
- Deglaze. Slowly whisk in 1 cup chicken broth, scraping up any browned bits from the pan. Those fond particles add deep, savory flavor to the sauce.
- Add cream and aromatics. Stir in 1 cup heavy cream and the 2 minced garlic cloves. Reduce the heat to low and let the sauce simmer gently for 4‑5 minutes, stirring occasionally, until it thickens enough to coat the back of a spoon.
- Finish with cheese. Remove the pan from heat and whisk in ½ cup grated Parmesan until melted and smooth. Taste and adjust seasoning with extra salt or pepper if needed.
Assembling & Baking
Preheat your oven to 375°F (190°C). In a large mixing bowl combine the cooked shells, seared chicken, and Alfredo sauce, tossing gently to coat everything evenly. Transfer the mixture to a greased 9×13‑inch baking dish, spreading it into an even layer. Sprinkle the top with 1 cup shredded mozzarella and an additional tablespoon of Parmesan for extra crust. Bake uncovered for 20‑25 minutes, or until the cheese is bubbly and golden brown. Let the bake rest for 5 minutes before serving to allow the sauce to set.
Tips & Tricks
Perfecting the Recipe
Dry the chicken. Patting the cubes dry before searing ensures a true crust and prevents steaming, which would dilute the sauce later.
Al dente pasta. Cook shells just shy of fully done; they will finish cooking in the oven without becoming mushy.
Don’t over‑mix. Gently fold the sauce with the pasta and chicken to keep the shells intact and the chicken pieces tender.
Flavor Enhancements
A splash of white wine added to the sauce after deglazing brightens the flavor. For a subtle heat, stir in ¼ teaspoon of red‑pepper flakes with the garlic. Finish the bake with a drizzle of truffle oil for an indulgent aroma.
Common Mistakes to Avoid
Avoid letting the sauce boil vigorously; high heat can cause the cream to separate, resulting in a grainy texture. Also, resist the urge to over‑bake—once the cheese is golden, the interior is already perfectly cooked.
Pro Tips
Use freshly grated Parmesan. Fresh cheese melts more smoothly and provides a brighter, nuttier flavor than pre‑grated varieties.
Pre‑heat the baking dish. A warm dish helps the bake rise evenly and reduces the risk of a soggy bottom.
Finish with fresh herbs. Sprinkle chopped parsley or basil just before serving for a pop of color and freshness.
Variations
Ingredient Swaps
Swap chicken for diced turkey, pork tenderloin, or even large shrimp for a surf‑and‑turf twist. Replace mozzarella with smoked gouda or sharp cheddar for a different flavor profile. If you prefer more veggies, fold in sautéed spinach, roasted broccoli, or caramelized onions before baking.
Dietary Adjustments
For a gluten‑free version, use gluten‑free flour and ensure the pasta shells are certified gluten‑free. To make it dairy‑free, substitute butter with olive oil, use a plant‑based cream (coconut or cashew) and dairy‑free cheese alternatives. Low‑carb eaters can replace shells with steamed cauliflower florets.
Serving Suggestions
Serve the bake alongside a simple arugula salad dressed with lemon vinaigrette, or pair it with garlic‑buttered crusty bread to mop up the sauce. For a complete meal, add a side of roasted asparagus or a buttery corn on the cob.
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 individual servings in freezer‑safe bags or containers for up to 3 months; wrap tightly with plastic wrap before sealing to avoid freezer burn.
Reheating Instructions
Reheat in a preheated 350°F oven, covered with foil, for 15‑20 minutes until heated through. Uncover for the last 5 minutes to re‑crisp the cheese. In a microwave, heat a single portion on medium power for 2‑3 minutes, stirring halfway, and add a splash of milk or broth to restore creaminess.
