Pesto Chicken Pasta Bake

The oven click is a sound I have always found oddly reassuring, and this pesto chicken pasta bake is the reason why. Something about pesto meeting cream under a dome of bubbling mozzarella makes the whole kitchen smell like someone actually knows what they are doing. I stumbled onto this combination one rainy Tuesday when the fridge held nothing but leftover pesto, half a carton of cream, and two lonely chicken breasts. Fifty minutes later I was eating straight from the baking dish, standing at the counter, not even bothering with a plate.

A friend once texted me at five in the afternoon asking what to make with a jar of pesto and some chicken, and I dictated this entire recipe from memory while stirring it myself at the same time.

Ingredients

• Penne or rigatoni (300 g): The tubular shape catches sauce in its hollow center, which is the whole point of choosing it over spaghetti here.
• Boneless skinless chicken breasts (350 g): Cutting them into uniform bite sized pieces ensures nothing dries out while everything cooks through evenly.
• Olive oil (1 tbsp): Just enough to keep the chicken from sticking without making the dish greasy.
• Salt and black pepper: Season the chicken before it hits the pan and you will taste the difference immediately.
• Basil pesto (120 g): Homemade is wonderful if you have basil to use up, but a good store bought jar saves the day on weeknights.
• Double cream (150 ml): This is what turns pesto from a condiment into a proper sauce that envelopes everything.
• Garlic (2 cloves, minced): Two cloves is the sweet spot where you notice it without it taking over.
• Sun dried tomatoes (50 g): Optional but they bring a tangy sweetness that cuts through the richness in a way you did not know you needed.
• Mozzarella (100 g, shredded): The stretchy golden blanket on top that makes everyone lean in closer when you pull it from the oven.
• Parmesan (40 g, grated): Sprinkled alongside the mozzarella for a salty, nutty finish that bakes into those irresistible crispy edges.
• Fresh basil leaves: Scatter them on at the very end for a pop of green and a fragrance that reminds you pesto started with something alive.

Instructions

Set the stage:

Preheat your oven to 200 degrees C and lightly grease a large baking dish so nothing sticks when you try to serve later.

Cook the pasta:

Boil the penne in well salted water until just al dente because it will cook a little more in the oven and nobody wants mushy pasta.

Brown the chicken:

Heat olive oil in a skillet over medium heat, add the seasoned chicken pieces, and sauté for five to six minutes until golden on the outside and no longer pink inside.

Bring it all together:

In a large bowl, toss the drained pasta with the chicken, pesto, cream, garlic, and sun dried tomatoes until every piece is coated and the mixture looks impossibly inviting.

Build the bake:

Transfer everything into your prepared dish and spread it out evenly, then shower the top with mozzarella and Parmesan so no pasta peeks through.

Bake until golden:

Slide it into the oven for about twenty minutes until the cheese is bubbling and touched with golden brown spots that signal dinner is ready.

Rest and garnish:

Let it sit for five minutes so the sauce settles and you do not burn your tongue, then scatter fresh basil leaves over the top if you have them.

I once made this for a neighbor who had just come home from the hospital, and she returned the empty dish three days later with a handwritten note asking for the recipe.

What to Serve Alongside

A simple arugula salad with lemon juice and olive oil is all you need beside this because the pasta bake is rich enough to carry the meal on its own.

Swaps and Shortcuts

Roasted zucchini, bell peppers, and mushrooms can replace the chicken entirely for a vegetarian version that is just as satisfying, and a handful of breadcrumbs scattered over the cheese before baking adds a crunch that changes everything.

Storing and Reheating

This keeps well in the fridge for up to three days and reheats in the microwave without losing its charm, which makes it one of those rare bakes that might actually taste better on day two.

• Cover the dish tightly with foil before refrigerating so it does not dry out.
• Reheat individual portions for about two minutes, adding a tiny splash of cream if the sauce looks tight.
• Freeze individual portions in airtight containers for up to one month and thaw overnight before reheating.

Some dinners are just fuel, and some are the reason you close the kitchen door and eat standing up. This one is the latter.

Recipe FAQs

→ Can I use store-bought pesto for this pasta bake?

Absolutely. Store-bought basil pesto works perfectly fine and saves time. If you have the ingredients on hand, homemade pesto will give you a fresher, more vibrant flavor.

→ What type of pasta works best?

Short, sturdy shapes like penne, rigatoni, or fusilli are ideal because they hold the creamy sauce well and stand up to baking without getting mushy.

→ Can I prepare this ahead of time?

Yes. You can assemble the entire dish, cover it tightly, and refrigerate it for up to 24 hours before baking. Add an extra 5–10 minutes to the baking time if going straight from the fridge.

→ How do I store and reheat leftovers?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave, or warm the whole dish in the oven at 180°C (350°F) until heated through.

→ Can I freeze pesto chicken pasta bake?

You can freeze it before or after baking. Wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. Note that the cream sauce may separate slightly upon thawing.

→ How can I make this dish vegetarian?

Simply swap the chicken for roasted vegetables like zucchini, bell peppers, and mushrooms. Use a vegetarian pesto (some store-bought versions contain Parmesan made with animal rennet).
