Ingredients
- 3 cups cooked chicken breast, diced
- 12 oz penne pasta
- 4 tablespoons unsalted butter
- 4 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 2 cups whole milk
- ½ cup heavy cream
- 4 oz cream cheese, softened
- 1½ cups freshly grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- 1 teaspoon Italian seasoning
- ½ teaspoon salt
- ½ teaspoon black pepper
- 2 tablespoons fresh parsley, chopped (optional)
Step-by-Step Directions
- Bring a large pot of salted water to a boil and cook the penne until just al dente. Drain well and set aside.
- Melt butter in a skillet over medium heat and add minced garlic. Cook briefly until fragrant, then whisk in flour and cook for one minute to remove the raw taste.
- Slowly whisk in milk and heavy cream, stirring constantly to avoid lumps. Let it simmer gently until the sauce thickens enough to coat the back of a spoon.
- Stir in softened cream cheese until fully melted, then add Parmesan, Italian seasoning, salt, and pepper. The sauce should look smooth and glossy.
- Add cooked pasta and diced chicken directly into the sauce. Stir gently to coat everything evenly without breaking the pasta.
- Transfer the mixture to a greased baking dish and spread evenly. Sprinkle mozzarella cheese over the top for that golden, bubbly finish.
- Bake at 375°F (190°C) for about 25–30 minutes, until the top is lightly browned and the edges are bubbling.
- Let the pasta bake rest for 5 minutes before serving. Sprinkle with fresh parsley for a bright, fresh contrast.
Make-Ahead / Meal Prep Options
- Prep the sauce, cook the pasta, and dice the chicken a day ahead; store components separately in airtight containers in the fridge for up to 24 hours.
- Assemble the casserole in the baking dish, cover tightly, and refrigerate for up to 24 hours—add 5–10 extra minutes to baking time if chilled.
- Fully baked leftovers keep well in the fridge for 3–4 days.
What to Serve With Garlic Parmesan Chicken Pasta Bake
- Simple green salad (mixed greens, lemon vinaigrette)
- Steamed or roasted broccoli or green beans
- Garlic bread or crusty Italian bread
- Light white wine (Pinot Grigio, Sauvignon Blanc) or iced tea
- Lemon sorbet or a fruit tart for dessert
Variations & Substitutions for Garlic Parmesan Chicken Pasta Bake
- Protein swaps: shredded rotisserie chicken, turkey, cooked Italian sausage, or cooked shrimp.
- Extra veggies: stir in spinach, sun-dried tomatoes, roasted red peppers, mushrooms, peas, or broccoli.
- Spice/sweetness changes: add red pepper flakes for heat, a pinch of nutmeg to the sauce for depth, or a touch of honey if you want a subtle sweet contrast.
- Dietary swaps: use gluten-free pasta and a GF flour (or cornstarch slurry) for gluten-free; substitute dairy-free milk, vegan cream cheese, and vegan Parmesan for a dairy-free/vegan version (texture and flavor will differ).
- Flavor twists / toppings: top with panko breadcrumbs mixed with melted butter for crunch, or finish with lemon zest and extra parsley for brightness.
How to Store, Freeze & Reheat Garlic Parmesan Chicken Pasta Bake
- Fridge: Store in an airtight container for 3–4 days. For the whole casserole, cover tightly with foil or plastic wrap.
- Freezer: Portion into freezer-safe containers or freeze the assembled (unbaked) casserole wrapped tightly for up to 2–3 months. Thaw overnight in the fridge before baking.
- Reheating: Oven: bake at 350°F (175°C) for 15–20 minutes (covered) until heated through, uncover for the last 5 minutes to refresh the top. Microwave: reheat individual portions in 1–2 minute intervals, stirring halfway; add a splash of milk if it seems dry.
Expert Tips for Garlic Parmesan Chicken Pasta Bake
- Use freshly grated Parmesan for the best flavor and melting texture—pre-grated powders don’t melt the same.
- Cook pasta just until al dente; it will finish cooking in the oven and absorb sauce.
- Warm the milk slightly before whisking into the roux to reduce lumps and speed thickening.
- Use cooked chicken to save time—rotisserie works great.
- Taste and adjust seasoning at the end; Parmesan adds salt, so start conservatively.
Garlic Parmesan Chicken Pasta Bake FAQs
Q: Can I use frozen chicken?
A: Yes—thaw and fully cook before adding to the sauce, or use pre-cooked frozen chicken that’s been reheated and diced.
Q: Can I make this gluten-free?
A: Yes—swap the penne for a gluten-free pasta and use a gluten-free flour or cornstarch slurry to thicken the sauce.
Q: Will this freeze well after baking?
A: It freezes fine, though the texture of the sauce may change slightly. For best results, freeze before baking and bake from thawed or partially thawed.
Q: How can I make it lighter?
A: Use 2% milk instead of whole milk and omit the heavy cream or reduce cream cheese by half; the sauce will be thinner but still tasty.
Q: Can I add vegetables directly to the bake?
A: Yes—lightly sauté firmer veggies (broccoli, carrots) first; softer veggies like spinach can be stirred in at the end.
