Pesto Chicken Pasta Bake

The rain was hammering against the kitchen window and I had two hungry kids orbiting the fridge like anxious satellites when I threw together whatever I could find: leftover pesto, some chicken, half a bag of penne, and a desperate handful of cheese. That chaotic evening birthed what my family now requests by name every single week without fail. The bubbling golden crust that emerged from the oven silenced every complaint about the weather. Sometimes the best recipes find you, not the other way around.

My neighbor Linda smelled it through the shared wall once and appeared at my door with a bottle of Pinot Grigio and zero shame. We stood in the kitchen eating straight from the baking dish while our kids ran wild in the backyard. Now it is our unofficial Friday night tradition and Linda always brings the wine.

Ingredients

• 300 g penne or rigatoni: The ridges on rigatoni are secret sauce catchers and worth seeking out if your shop has them.
• 2 boneless skinless chicken breasts (350 g): Cut them into uniform bite sized pieces so everything cooks evenly without any chewy surprises.
• 1 tbsp olive oil: A fruity olive oil makes a noticeable difference when searing the chicken.
• 1/2 tsp salt and 1/4 tsp black pepper: Season the chicken generously before it hits the pan and you will taste the improvement.
• 120 g basil pesto: Homemade pesto is lovely but a good store bought jar saves the day on weeknights without apology.
• 150 ml double cream: This is what transforms pesto from a condiment into a proper sauce that blankets every noodle.
• 2 cloves garlic minced: Fresh garlic mashed into the creamy sauce creates a backbone of warmth you simply cannot skip.
• 50 g sun dried tomatoes chopped: These little ruby pieces cut through the richness with a tangy sweetness that surprises people.
• 100 g shredded mozzarella: Use the low moisture kind for the best melt and those dramatic cheese pulls.
• 40 g grated Parmesan: Aged Parmesan grated fresh over the top creates that deeply savory golden crust.
• Fresh basil leaves: Torn over the finished bake at the very last second for color and a hit of brightness.

Instructions

Get the oven hot and ready:

Preheat your oven to 200 degrees Celsius (400 degrees Fahrenheit) and rub a generous swipe of butter or oil across your baking dish so nothing sticks later.

Boil the pasta to just barely done:

Cook the penne in well salted boiling water until it is a minute shy of package directions because it will finish cooking in the oven and nobody wants mushy pasta.

Sear the chicken until golden:

Heat olive oil in a skillet over medium heat, add the seasoned chicken pieces, and let them sit undisturbed for a few minutes until a deep golden crust forms before stirring.

Bring everything together in a big bowl:

Toss the drained pasta, seared chicken, pesto, cream, garlic, and sun dried tomatoes together until every single noodle is coated in that gorgeous green sauce.

Load the dish and blanket with cheese:

Pour the whole mixture into your prepared baking dish and scatter mozzarella and Parmesan evenly across the top so every serving gets a proper cheesy lid.

Bake until bubbly and irresistible:

Slide it into the oven for about twenty minutes until the edges are bubbling aggressively and the cheese has turned a patchy gorgeous gold.

Rest then garnish and serve:

Let it sit for five minutes so the sauce settles back into the pasta instead of running everywhere, then scatter fresh basil leaves over the top and bring it to the table.

Save

The night my youngest said this was better than the restaurant down the street I felt a ridiculous swell of pride over pasta and pesto. Food does that though, it turns ordinary Tuesday evenings into something worth remembering.

Making It Your Own

I have tossed in roasted red peppers when I had them, swapped chicken for sauteed mushrooms when a vegetarian friend joined us, and even crumbled crispy breadcrumbs on top when I wanted extra texture. The recipe bends without breaking every single time.

What to Serve Alongside

A sharp arugula salad with lemon dressing cuts right through the richness of this bake beautifully. A chilled glass of Sauvignon Blanc or Pinot Grigio beside it transforms a casual dinner into something that feels almost like a celebration.

Storing and Reheating Leftovers

Leftovers keep wonderfully in the fridge for up to three days and reheat in the microwave with a splash of cream to bring the sauce back to life. I actually think the flavors deepen overnight and the next day portion tastes even better than the first.

• Store in an airtight container to keep the pasta from absorbing all the sauce in the fridge.
• Avoid freezing because the cream sauce can separate and become grainy when thawed.
• Always reheat gently and stir halfway through to distribute the heat evenly.

Save

This dish asks for nothing fancy, just a little attention and a willingness to let cheese do what cheese does best. Share it with someone you love and watch the conversation pause the moment the first forkful hits.

Recipe FAQs

→ Can I use a different type of pasta?

Yes, any short pasta shape works well. Rigatoni, fusilli, farfalle, or cavatappi are all great alternatives to penne. The key is choosing a shape that holds onto the creamy pesto sauce and fits well in a baking dish.

→ Can I make this ahead of time?

Absolutely. Assemble the entire dish, cover tightly, and refrigerate for up to 24 hours before baking. Add an extra 5–10 minutes to the baking time if going straight from the refrigerator to the oven.

→ What can I substitute for double cream?

Heavy cream is a direct substitute. For a lighter version, you can use half-and-half or whole milk, though the sauce will be slightly less rich. Avoid using low-fat milk as it may not thicken properly during baking.

→ 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 for 2–3 minutes, or warm the whole dish in the oven at 180°C (350°F) for about 15 minutes until heated through.

→ Can I freeze pesto chicken pasta bake?

Yes, it freezes well. Assemble the dish without baking, wrap tightly in foil, and freeze for up to 2 months. Thaw overnight in the refrigerator, then bake as directed, adding about 10 extra minutes to account for the cold start.

→ How do I get a golden, crispy cheese topping?

For an extra golden finish, switch the oven to broil for the last 2–3 minutes of cooking. Keep a close eye on it to prevent burning. Sprinkling a layer of breadcrumbs mixed with a little melted butter before baking also adds a satisfying crunch.
