Creamy Pesto Chicken Pasta

The first time I made this pasta bake, I was hosting a last-minute dinner for friends who'd just moved into their new apartment. We were all exhausted from unpacking boxes, and I needed something that felt special but didn't require standing at the stove for hours. When that bubbling, golden-topped dish emerged from the oven, filling their tiny kitchen with the most incredible garlic and basil aroma, I knew I'd found my weeknight savior.

Last winter, when my sister came home after a long hospital shift craving something nourishing but not heavy, I made this for her. She sat at the counter watching the cheese bubble through the oven door, and later told me it was the first time in weeks she'd felt truly comforted by food. Sometimes the simplest dishes hold the most heart.

Ingredients

• 12 oz short pasta: Penne or rigatoni catch the creamy sauce in their ridges, and cooking them slightly under al dente prevents mushiness during baking
• 2 cups cooked chicken breast: Rotisserie chicken works beautifully here, or poach your own breasts earlier in the week for meal prep efficiency
• 1 cup heavy cream: Creates that luxurious velvety base that coats every piece of pasta
• 1/2 cup basil pesto: Store-bought saves time, but homemade with fresh basil, pine nuts, and good olive oil transforms this entirely
• 1/2 cup freshly grated Parmesan cheese: Pre-grated has anti-caking agents that prevent smooth melting, so buy a wedge and grate it yourself
• 1/2 cup chicken broth: Prevents the sauce from becoming too thick as it bakes
• 2 cloves garlic, minced: Fresh garlic mellows beautifully in the cream, creating subtle depth rather than harsh raw bite
• 1/2 tsp black pepper: Freshly cracked pepper adds warmth that cuts through the richness
• 1/4 tsp salt: Adjust this based on whether your pesto and chicken are already seasoned
• 1 cup cherry tomatoes: They burst during baking, releasing sweet juices that balance the creamy elements
• 1 cup baby spinach: Wilts gently into the pasta, adding color and nutrition without overwhelming the dish
• 1 cup shredded mozzarella cheese: Creates that irresistible golden cheese pull
• 1/4 cup freshly grated Parmesan: Extra Parmesan on top adds salty, nutty flavor and helps achieve beautiful browning

Instructions

Preheat your oven:

Set it to 375°F and generously grease a 9x13-inch baking dish with butter or cooking spray, paying attention to the corners

Cook the pasta:

Boil it in salted water for exactly 2 minutes less than the package directs, then drain immediately to stop the cooking process

Build the sauce base:

In a large skillet over medium heat, whisk together heavy cream, pesto, chicken broth, garlic, salt, and pepper until simmering gently

Add the Parmesan:

Stir in the cheese gradually, allowing each handful to melt completely before adding more, until the sauce becomes silky smooth

Combine everything:

Add the drained pasta, chicken, cherry tomatoes, and spinach to the skillet, tossing until every piece is coated in that gorgeous green-flecked cream

Transfer to the baking dish:

Pour the mixture into your prepared dish, spreading it evenly so no pasta is left exposed

Add the cheese topping:

Sprinkle mozzarella and extra Parmesan across the surface, covering most areas for maximum golden coverage

Bake until bubbly:

Place in the oven for 20 to 25 minutes until the cheese is deeply golden in spots and the sauce is bubbling around the edges

Let it rest:

Wait 5 minutes before serving to allow the sauce to thicken slightly, making it easier to scoop and serve

This became my daughter's most-requested birthday dinner after she tried it at age eight. Now every year she asks for it instead of cake, and honestly, watching her face light up when those first cheese-covered bites emerge from the oven has become its own kind of celebration.

Making It Your Own

I've discovered that this recipe welcomes substitutions beautifully. Sometimes I add sun-dried tomatoes for extra depth, or swap in Italian sausage for the chicken when I want something with more punch. The beauty lies in how the creamy pesto foundation supports whatever you're craving.

Perfect Pairings

A crisp green salad with acidic vinaigrette cuts through the richness perfectly, and I almost always serve this alongside garlic bread for soaking up any extra sauce. My husband swears by pairing it with a bright Sauvignon Blanc that highlights the basil notes.

Make-Ahead Magic

You can assemble the entire dish up to 24 hours ahead, cover it tightly, and refrigerate until ready to bake. Just add an extra 5 to 10 minutes to the cooking time if baking cold from the refrigerator. This has saved me countless times when hosting dinner parties.

• Let leftovers cool completely before storing, and they'll keep beautifully for up to 4 days
• Reheat individual portions in the microwave with a splash of milk to revive the sauce
• Freeze unbaked portions for up to 3 months, then thaw overnight before baking as directed

There's something deeply satisfying about serving a dish that looks impressive but came together with such ease. May your kitchen be filled with the scent of bubbling cheese and happy voices gathered around the table.

Recipe FAQs
