Creamy Pesto Chicken Pasta

There’s an almost irresistible first moment with this dish: the bright, herbaceous perfume of basil pesto lifted by warm garlic, mingling with the rich, buttery aroma of melted Parmesan and mozzarella. The first bite gives you pillowy pasta coated in a silky, herb-green sauce, tender morsels of golden chicken, and the satisfying pull of bubbling cheese. It’s comfort food with a little herbaceous flare — luxe but approachable.

Serve this when you need to turn a busy weeknight into something special, impress a small dinner crowd, or soothe chilly evenings with something creamy and familiar. It also reheats beautifully for meal prep and can be adapted for lighter or gluten-free diets. If you enjoy dishes with a creamy finish and bright herb notes, you might also like a chilled take on pasta—see this creamy chicken pasta salad for inspiration.

Why You’ll Love It

• Irresistible aroma and flavor contrast: bright basil pesto cuts through the richness of cream and cheeses, giving you layers of flavor in each bite.
• Comfort with a fresh twist: this feels like classic baked pasta but with an herb-forward personality that keeps it from being too heavy.
• Crowd-pleasing and flexible: serve it for family dinners, potlucks, or a cozy date night; it’s easy to scale and adapts well to substitutions.
• Good source of protein: with chicken and cheese, it delivers a satisfying protein boost while staying indulgent.

Method & Process

Ingredients

• 10.5 ounces penne or rigatoni pasta (about 297 g)
• 2 medium boneless, skinless chicken breasts, diced (about 10.5 ounces / 297 g total)
• 1 tablespoon olive oil
• Salt and freshly ground black pepper, to taste
• 1 tablespoon unsalted butter
• 2 cloves garlic, minced
• 3/4 cup plus 2 tablespoons heavy cream (total = 1/2 cup / 120 ml)
• 1/2 cup whole milk (120 ml)
• 1/2 cup basil pesto (store-bought or homemade)
• 3/4 cup grated Parmesan cheese (about 75 g)
• 3.5 ounces baby spinach (optional, about 100 g)
• 1 cup shredded mozzarella cheese (about 112 g)
• 1/4 cup grated Parmesan cheese (for topping, about 25 g)

Optional ingredients and substitutions

• Use grilled or rotisserie chicken instead of sautéing for speed.
• Substitute half-and-half or Greek yogurt thinned with milk for reduced-fat cream (note texture will be less rich).
• Swap gluten-free pasta to make it GF (cook according to package directions).
• For a dairy-free version: use a vegan cream substitute, dairy-free pesto or make a nut-free basil sauce, and vegan cheeses.
• Add sun-dried tomatoes or roasted red peppers for extra brightness.

Equipment and prep

• Preheat oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.
• In a large pot of boiling salted water, cook pasta for 2 minutes less than package directions so it’s just under al dente. Drain and set aside.

Step-by-step instructions

1. Heat olive oil in a large skillet over medium-high heat. Season diced chicken with salt and pepper, then sauté until cooked through and lightly golden, about 5–6 minutes. Remove chicken to a plate.
2. In the same skillet, reduce heat to medium and melt the butter. Add minced garlic and sauté about 30 seconds until fragrant (don’t let it brown).
3. Stir in heavy cream and whole milk. Bring to a gentle simmer and cook 2–3 minutes until slightly thickened, stirring occasionally.
4. Mix in the 1/2 cup basil pesto and 3/4 cup grated Parmesan, stirring until the sauce is smooth and the cheese has melted. Taste and adjust seasoning with salt and pepper.
5. Return the cooked chicken, drained pasta, and spinach (if using) to the skillet. Toss gently but thoroughly until everything is evenly coated with the pesto cream sauce. (Tip: if the sauce seems too stiff, add a splash of pasta water or milk to loosen.)
6. Transfer the coated mixture into the prepared 9×13 baking dish. Evenly sprinkle the 1 cup shredded mozzarella and extra 1/4 cup grated Parmesan over the top.
7. Bake uncovered for 20–25 minutes, until the cheese is golden and bubbly and the casserole edges are lightly caramelized.
8. Allow the dish to rest for 5 minutes before serving to let the sauce set slightly.

Practical tips

• Avoid overcooking pasta in the stovetop stage; it will finish cooking in the oven.
• If your pesto is very salty, reduce added salt until after you taste the finished sauce.
• For a creamier finish, stir 1–2 tablespoons of reserved pasta water into the sauce before baking.
• Use a shallow baking dish so the casserole heats evenly and the top crisps.

Best Pairings

• Simple green salad with lemon vinaigrette to cut through richness.
• Garlic bread or crusty baguette for mopping up the sauce.
• Roasted vegetables (asparagus or broccoli) for added texture and color.
• A light white wine (Pinot Grigio or Sauvignon Blanc) or a chilled sparkling water with lemon.
• For a brunch twist, serve smaller portions alongside scrambled eggs and a citrusy fruit salad.

Storage Instructions

• Room temperature: Do not leave cooked pasta casserole at room temperature more than 2 hours (per USDA food safety guidance).
• Refrigeration: Store leftovers in airtight containers for 3–4 days. Reheat gently in the oven at 350°F (175°C) or on the stovetop with a splash of milk to loosen the sauce.
• Freezer: Freeze in airtight, freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating; reheat covered in a 350°F oven until warmed through. Note: texture of pasta may change slightly after freezing.

Chef’s Advice

• Best pasta shape: rigatoni or penne work superbly because their ridges and hollow centers trap the creamy pesto sauce.
• Cheese choices: use low-moisture mozzarella for better melting and less water release. Freshly grated Parmesan melts more smoothly than pre-grated powders.
• Don’t overcrowd the skillet when browning chicken — do it in batches if needed to get a light golden sear (this adds flavor).
• Don’t overbake: once the top is golden and the edges are bubbling, remove it to avoid drying the pasta.
• For a lighter version, reduce heavy cream by half and increase milk, then add 1–2 tablespoons of cornstarch slurry (1:1 cornstarch to water) to help thicken without extra fat.

Creative Twists

1. Mediterranean: Stir in chopped sun-dried tomatoes, kalamata olives, and a handful of arugula after baking. Finish with lemon zest.
2. Vegan: Use a dairy-free cream (oat-based or cashew cream), a store-bought vegan pesto (or blended basil+olive oil+toasted walnuts), and vegan mozzarella. Bake as directed.
3. Low-carb / Keto: Replace pasta with lightly blanched zucchini noodles or shirataki rigatoni; reduce bake time and watch for moisture.
4. Spicy kick: Add 1/2 teaspoon red pepper flakes to the sauce or fold in a spoonful of harissa for warm heat.
5. One-pan shortcut: Brown chicken, then cook pasta directly in the sauce (add extra liquid) for a one-pot version — reduce oven time accordingly.

Recipe Q&A

Q: Can I use rotisserie chicken instead of cooking raw chicken?
A: Yes — use about the same weight (10–11 ounces shredded) and fold it in at step 5; reduce sauté time accordingly.

Q: My casserole looks watery after baking. How do I fix it?
A: Let it rest 5–10 minutes; the sauce will thicken as it cools. If still too loose, reheat uncovered to evaporate excess moisture or stir in a small amount of grated cheese while warming.

Q: How can I reduce the calories/fat without losing flavor?
A: Substitute half the cream with low-fat milk or unsweetened almond milk and use part-skim mozzarella and less pesto (or a lighter pesto). Increase fresh herbs and lemon to boost perceived flavor.

Q: Can this be assembled ahead?
A: Yes — assemble up to the point before baking, cover, and refrigerate for up to 24 hours. Add 5–10 minutes to baking time if cold from fridge.

Q: Is this safe to freeze?
A: Yes — freeze in airtight containers for up to 2 months. Thaw overnight in the refrigerator before reheating.
