Step-by-step overview
Before you dive in, here’s the simple flow so you know what to expect:
- Par-cook the pasta a bit under al dente so it finishes in the oven.
- Sauté diced chicken until golden and cooked through.
- Build a quick creamy pesto sauce in the same skillet.
- Toss pasta, chicken, and optional spinach into the sauce.
- Transfer to a baking dish, top with mozzarella and extra Parmesan, then bake until bubbly and golden.
- Rest a few minutes, then serve.
This structure keeps the pasta tender and the sauce well-distributed.
What you’ll need
- 10.5 ounces penne or rigatoni pasta
- 2 medium boneless, skinless chicken breasts, diced (about 10.5 ounces 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
- 1/2 cup whole milk
- 1/2 cup basil pesto (store-bought or homemade)
- 3/4 cup grated Parmesan cheese (for the sauce)
- 3.5 ounces baby spinach (optional, for extra nutrition)
- 1 cup shredded mozzarella cheese (for topping)
- 1/4 cup grated Parmesan cheese (for topping)
Notes and substitutions:
- Use rotini or fusilli if you prefer more nooks to trap the sauce.
- For a lighter version, swap half-and-half for the heavy cream, but the sauce will be thinner.
- Use pre-grated Parmesan for speed, but freshly grated melts and tastes better.
Step-by-step instructions
- Preheat the oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish.
- Bring a large pot of salted water to a boil. Cook the pasta for 2 minutes less than package directions so it’s just under al dente. Drain and set aside.
- Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Season diced chicken with salt and pepper. Sauté the chicken until cooked through and lightly golden, about 5–6 minutes. Remove the chicken from the skillet and set aside.
- Reduce heat to medium and add 1 tablespoon unsalted butter to the same skillet. Add minced garlic and sauté for about 30 seconds until fragrant.
- Stir in 3/4 cup plus 2 tablespoons heavy cream and 1/2 cup whole milk. Bring to a gentle simmer and cook for 2–3 minutes until the sauce slightly thickens.
- Mix in 1/2 cup basil pesto and 3/4 cup grated Parmesan cheese. Stir until the sauce is smooth and the Parmesan is melted. Taste and adjust salt and pepper.
- Return the cooked chicken and drained pasta to the skillet. Add the 3.5 ounces baby spinach now if using, and toss everything thoroughly so the pasta and chicken are evenly coated.
- Transfer the mixture into the prepared baking dish. Sprinkle 1 cup shredded mozzarella and 1/4 cup grated Parmesan evenly over the top.
- Bake uncovered for 20–25 minutes, until the cheese is golden and bubbly.
- Allow the dish to rest for 5 minutes before serving.
Pro timing tip: while the dish bakes, set the table or prepare a simple side salad so the meal comes together smoothly.
Best ways to enjoy it
This dish pairs beautifully with crisp textures and high-acid contrasts to cut the richness:
- Serve with a peppery arugula salad dressed simply in lemon and olive oil.
- A crisp green vegetable like roasted asparagus or broccoli rabe balances the creaminess.
- If you want a crunchy topping, sprinkle toasted bread crumbs mixed with a little olive oil on top before baking, or check the similar pesto chicken pasta bake for ideas on crispier finishes and presentation.
- For wine: a chilled Sauvignon Blanc or a light-bodied Pinot Grigio complements the herbal pesto notes.
Plate it in shallow bowls for family-style serving or bake and bring straight to the table for casual gatherings.
Storage and reheating tips
- Refrigeration: Store leftovers in an airtight container for up to 3–4 days. Cool to room temperature (no more than 2 hours) before refrigerating.
- Freezing: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Reheat gently in a 350°F oven covered with foil for 15–20 minutes (longer if frozen and thawed). For single servings, microwave on medium power in 45–60 second intervals, stirring between bursts to ensure even heat. Add a splash of milk or cream if the sauce appears dry.
- Food safety: Reheat to an internal temperature of 165°F (74°C) before serving.
Helpful cooking tips
- Undercook pasta on purpose: boiling 2 minutes less than package directions prevents the macaroni from turning mushy after baking.
- Check chicken doneness: diced pieces cook faster; they should reach 165°F internally or be fully opaque with no pink.
- Avoid a watery bake: don’t overload with wet vegetables. If using frozen spinach, squeeze excess moisture well.
- Cheese choices: whole-milk mozzarella gives better melt and stretch. A blend with provolone can add flavor depth.
- Make it ahead: Assemble up to the point of baking, cover, and refrigerate for up to 24 hours. Add 5–10 extra minutes to the baking time if chilled.
- For a silkier sauce: grate your own Parmesan and add it slowly off-heat to avoid clumping.
Creative twists
- Vegetarian: Omit the chicken and add roasted mushrooms, artichoke hearts, or cannellini beans for protein.
- Low-carb: Use spiralized zucchini or a chickpea pasta to reduce refined carbs.
- Spicy pesto: Stir in red pepper flakes or a spoonful of harissa to add heat.
- Mediterranean: Add sun-dried tomatoes, olives, and a sprinkle of feta after baking.
- Kid-friendly: Leave out spinach and use plain pesto — serve with garlic bread for little appetites.
- For a smoky flavor: swap half the mozzarella for smoked provolone and sprinkle smoked paprika on top before baking.
Common questions
Q: Can I use rotisserie or pre-cooked chicken?
A: Yes. Dice the rotisserie chicken and fold it into the sauce in step 7 — you’ll save time and still get great flavor. Adjust seasoning because rotisserie chicken can be saltier.
Q: Can I make this ahead and bake later?
A: Absolutely. Assemble the pasta and sauce in your baking dish, cover tightly, and refrigerate for up to 24 hours. Add a few extra minutes to the bake time and ensure it’s heated through to 165°F.
Q: Is it safe to freeze this pasta bake?
A: Yes — store in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator and reheat in the oven covered with foil. Freshly baked texture is best, but it reheats well.
Q: Can I reduce the cream without losing texture?
A: If you want lighter sauce, use half-and-half or reduce heavy cream by 2–3 tablespoons and add a touch more Parmesan to help thicken it. The result will be slightly less rich but still satisfying.
Q: My sauce separated — how can I fix it?
A: Return the skillet to low heat and whisk in a tablespoon of cream or warm milk gradually. Avoid boiling the sauce once the cheese is added to prevent separation.
