Creamy Pesto Chicken Pasta Bake

The first time I made this pesto chicken pasta bake, I was rushing to get dinner on the table before my sister arrived for an unexpected visit. My kitchen was already a disaster from earlier cooking experiments, and I basically threw everything into one baking dish hoping for the best. When she walked in, the smell of bubbling cheese and basil filled the entire house. She still asks for this recipe every time she visits.

Last winter, my neighbor texted me saying she was having one of those days where everything felt overwhelming. I brought over a container of this pasta bake still warm from the oven. We ended up sitting at her kitchen table for hours, eating straight from the dish and talking about everything and nothing. Food has this way of turning rough days into something manageable.

Ingredients

• 12 oz short pasta (penne or rigatoni): These shapes catch all that creamy sauce in their ridges and tubes
• 2 cups cooked chicken breast: Rotisserie chicken works perfectly here if you want to skip a step
• 1 cup heavy cream: Creates that luxuriously rich base that makes this dish so comforting
• 1/2 cup basil pesto: Store-bought is totally fine, but homemade adds something special
• 1/2 cup freshly grated Parmesan cheese: The kind in the tub does not melt the same way
• 1/2 cup chicken broth: Thins the sauce just enough so it coats everything evenly
• 2 cloves garlic, minced: Fresh garlic makes a difference you can really taste
• 1/2 tsp black pepper: Adds just enough warmth to cut through the richness
• 1/4 tsp salt: The cheese and pesto are already salty, so go easy here
• 1 cup cherry tomatoes, halved: They burst in the oven and add little pockets of brightness
• 1 cup baby spinach, chopped: Wilts down into the sauce and makes you feel slightly virtuous
• 1 cup shredded mozzarella cheese: That golden bubbly top is what everyone reaches for first
• 1/4 cup freshly grated Parmesan cheese: Sprinkled on top for that irresistible cheesy crust

Instructions

Get your oven ready:

Preheat to 375°F and grease a 9x13 baking dish with butter or cooking spray

Cook the pasta:

Boil the pasta in salted water until 2 minutes shy of al dente since it will finish cooking in the oven

Make the creamy sauce:

Combine cream, pesto, broth, garlic, salt, and pepper in a large skillet and simmer for 2 minutes

Add the cheese:

Stir in the Parmesan until melted and smooth, watching it carefully so the sauce does not break

Combine everything:

Add the drained pasta, chicken, tomatoes, and spinach to the skillet and toss until coated

Transfer to baking dish:

Pour the mixture into your prepared dish and spread it evenly

Top with cheese:

Sprinkle mozzarella and extra Parmesan over the top covering everything generously

Bake until bubbly:

Bake for 20 to 25 minutes until the cheese is golden and the sauce is bubbling up the sides

Let it rest:

Wait 5 minutes before serving so the sauce sets slightly and each serving holds together

Save

My daughter asked if we could have breakfast for dinner last night, but when she smelled this baking, she changed her mind immediately. There is something about that pesto aroma that makes people drop what they are doing and wander into the kitchen. This recipe has become my go-to for bringing comfort to anyone who needs it.

Make It Your Own

I have made so many versions of this dish depending on what is in my fridge. Sometimes I add sun-dried tomatoes when I want something more intense. Other times I throw in artichoke hearts or roasted red peppers. The basic formula stays the same but you can customize it endlessly.

Perfect Pairings

A crisp green salad with vinaigrette cuts through all that richness perfectly. I also love serving this with garlic bread for soaking up any extra sauce. A light white wine like Pinot Grigio balances the heavy cream without competing with the pesto.

Storage and Reheating

This pasta bake actually tastes better the next day as the flavors meld together. Store it in the refrigerator for up to 4 days in an airtight container. When reheating, add a splash of cream or broth to bring back that silky texture.

• Cover with foil when reheating so the top does not dry out
• Individual portions reheat beautifully in the microwave
• Let the dish come to room temperature before covering for storage

There is nothing quite like pulling this bubbling dish out of the oven and watching everyone gather around, utensils ready. Hope this recipe brings as much comfort to your table as it has to mine.
