Ingredients You Need
- Short pasta: 12 ounces penne, rigatoni, or rotini. Choose shapes with ridges for extra sauce cling.
- Cooked chicken: 3 cups shredded or cubed. Use rotisserie chicken for a shortcut or sauté bite-size pieces in olive oil with salt and pepper.
- Basil pesto: 1 cup. Refrigerated pesto tastes brightest; I like Costco Kirkland or Rao’s. Jarred shelf-stable works in a pinch.
- Creamy base: 1 cup heavy cream or half-and-half, plus 4 ounces cream cheese. These two make the creamiest sauce without splitting.
- Broth: 1 cup low sodium chicken broth to loosen the sauce.
- Aromatics: 3 cloves garlic minced. Add 1 small shallot if you want extra depth.
- Veggies: 2 cups baby spinach or 1 cup peas. Sun-dried tomatoes add a savory pop.
- Cheese: 1.5 cups shredded low-moisture mozzarella and 1/2 cup grated Parmesan or pecorino.
- Lemon: 1 teaspoon zest and 1 teaspoon juice to brighten the creamy pesto sauce.
- Seasoning: 1/2 teaspoon kosher salt, 1/2 teaspoon black pepper, 1/4 teaspoon red pepper flakes.
- Olive oil: 1 tablespoon for sautéing.
- Optional crunch: 1/2 cup panko tossed with 1 tablespoon olive oil and a pinch of salt.

How to Make Creamy Pesto Chicken Pasta Bake Recipe
Heat the oven and boil the pasta
- Heat oven to 375 degrees F. Grease a 9×13 baking dish.
- Boil pasta in generously salted water until just shy of al dente, about 1 minute less than package time. Drain and set aside.
Build the creamy pesto sauce
- Warm 1 tablespoon olive oil in a skillet over medium heat. Sauté garlic 30 seconds until fragrant.
- Whisk in broth and cream. Add cream cheese in small cubes and whisk until smooth, 2 to 3 minutes.
- Stir in pesto, lemon zest, lemon juice, salt, pepper, and red pepper flakes. Taste and adjust seasoning.
Add the chicken and veggies
- Fold in cooked chicken and spinach or peas. Let the spinach wilt for 30 to 60 seconds.
- Stir in 1/2 cup mozzarella and 2 tablespoons Parmesan to enrich the sauce.
Combine and assemble
- Toss the drained pasta with the sauce mixture until every piece looks coated.
- Pour into the prepared baking dish. Top with remaining mozzarella and Parmesan.
- If you like crunch, sprinkle oiled panko on top.
Bake to golden and bubbly
- Bake 18 to 22 minutes until the cheese bubbles and turns light golden.
- Let the pasta bake rest 5 minutes so the sauce thickens and clings. Garnish with extra basil if you have it.
Tips & Common Mistakes
- Salt the pasta water like the sea to season from the inside out.
- Pull the pasta a minute early so it finishes in the oven and stays tender, not mushy.
- Use room temp cream cheese so it melts smooth and avoids clumps.
- Choose refrigerated pesto for brighter basil flavor; jarred works when time runs tight.
- Do not drown the pasta. The sauce will thicken in the oven, so keep it slightly loose before baking.
- Shred your own mozzarella to avoid anti-caking additives that block melting.
- Taste the sauce before mixing with pasta and adjust salt, pepper, and lemon.
- Let the bake rest 5 minutes to set up clean scoops and avoid a runny pool.
Variations I've Tried
- Broccoli cheddar pesto: Swap spinach for small broccoli florets and add sharp cheddar with mozzarella.
- Spicy Calabrian kick: Stir in 1 tablespoon Calabrian chili paste and extra red pepper flakes.
- Roasted red pepper pesto: Blend 1/2 cup roasted red peppers into the pesto for a sweeter, smoky note.
- Tomato basil twist: Add 1 cup halved cherry tomatoes right before baking for juicy pops.
- Turkey or sausage: Use leftover turkey or brown Italian chicken sausage for a heartier bake.
- Gluten-free: Use your favorite gluten-free pasta and check labels on broth and pesto.
- Lighter option: Use half-and-half and reduce mozzarella by 1/2 cup; the bake still tastes creamy.
How to Serve
Spoon generous scoops into warm bowls and shower with fresh basil, extra Parmesan, and a squeeze of lemon. Pair with a crisp green salad and garlicky vinaigrette to cut through the rich creamy pesto sauce. Serve with garlic bread or a warm baguette to swipe up every last bit. A chilled pinot grigio or a light-bodied red makes a friendly match.
Make-Ahead and Storage
- Make-ahead unbaked: Assemble, cover tightly, and refrigerate up to 24 hours. Bake covered 15 minutes, then uncover and finish 15 to 20 minutes until hot and bubbly.
- Make-ahead baked: Bake fully, cool, and refrigerate up to 4 days. Reheat covered at 350 degrees F for 20 to 25 minutes until hot.
- Freezer: Wrap the unbaked dish well and freeze up to 2 months. Thaw in the fridge overnight, then bake as directed, adding 5 to 10 extra minutes.
- Best reheating: Add a splash of milk or broth, cover, and warm in a 350 degrees F oven or on the stovetop over low heat. Stir once or twice so the sauce loosens and turns silky again.

Ingredients
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
- Cook the pasta in a large pot of salted boiling water until just al dente, 1–2 minutes less than package directions. Drain and set aside.
- While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Add the chicken pieces and cook, stirring occasionally, until lightly browned and cooked through, about 6–8 minutes. Transfer the chicken to a plate and set aside.
- In the same skillet, add the chopped onion and cook until softened, about 3–4 minutes. Stir in the minced garlic and cook until fragrant, about 30 seconds.
- Reduce heat to medium, then add the pesto, heavy cream, and chicken broth. Stir to combine and bring to a gentle simmer. Season with salt, black pepper, and Italian seasoning if using. Simmer 3–4 minutes until slightly thickened.
- Add the cooked chicken back into the skillet and stir to coat in the creamy pesto sauce.
- In a large bowl, combine the drained pasta with the creamy pesto chicken mixture. Toss until the pasta is evenly coated.
- Transfer the mixture to the prepared baking dish. Sprinkle the mozzarella and Parmesan cheese evenly over the top.
- Bake for 18–22 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
- Remove from the oven and let rest for 5 minutes. Garnish with chopped fresh basil if desired, then serve warm.
