Pesto Chicken Pasta Bake

The oven had barely hit temperature when my neighbor knocked on the door holding a jar of homemade basil pesto she would not take no for an answer on. That jar sat on my counter staring at me until I rifled through the fridge and found chicken breasts, half a bag of penne, and a block of mozzarella that had seen better days but was still perfectly good for grating. What came out of the oven forty minutes later was the kind of golden, bubbling dish that makes everyone linger at the table long after the plates are empty.

I made this on a Tuesday when the rain would not stop and my kids kept circling the kitchen asking when dinner would be ready. The smell of garlic hitting the skillet mixed with that vivid green pesto was enough to quiet the whole house for a solid ten minutes.

Ingredients

• Penne or rigatoni (300 g): The ridges on rigatoni grab the sauce better than smooth pasta, but penne works perfectly fine if that is what the pantry offers up.
• Boneless skinless chicken breasts (2, about 350 g): Cutting them into uniform bite sized pieces ensures everything cooks through evenly without drying out.
• Olive oil (1 tbsp): Just enough to get a good sear on the chicken without making the dish greasy.
• Salt (1/2 tsp) and black pepper (1/4 tsp): Seasoning the chicken directly before cooking makes a noticeable difference compared to salting at the end.
• Basil pesto (120 g): Store bought is completely fine here, though a generous dollop of homemade will turn this into something people remember.
• Double cream or heavy cream (150 ml): This is what transforms pesto from a condiment into a proper sauce that hugs the pasta.
• Garlic, minced (2 cloves): Fresh garlic minced right before cooking gives a punch that the jarred version simply cannot match.
• Sun dried tomatoes, chopped (50 g, optional): They add little bursts of tangy sweetness that break up the richness in the best way.
• Shredded mozzarella (100 g): The mild stretchiness is exactly what a baked pasta needs on top.
• Grated Parmesan (40 g): Mixed with the mozzarella, it brings a salty depth that keeps the topping from being one note.
• Fresh basil leaves (optional): Torn and scattered on top at the very end for color and a hit of freshness.

Instructions

Get the oven ready:

Preheat your oven to 200 degrees C (400 degrees F) and lightly grease a large baking dish so nothing sticks 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 mushy pasta is a tragedy worth avoiding.

Sear the chicken:

Heat olive oil in a skillet over medium heat, add the seasoned chicken pieces, and let them sit undisturbed for a minute or two so they actually get golden before you stir.

Bring it all together:

In your largest bowl, toss the drained pasta, cooked chicken, pesto, cream, garlic, and sun dried tomatoes until every piece of pasta looks coated and happy.

Build the bake:

Pour the whole mixture into your prepared dish, scatter the mozzarella and Parmesan over the top, and try not to eat the cheese straight from the grater while you work.

Bake until golden:

Slide it into the oven for about twenty minutes until the edges are bubbling and the cheese has those irresistible brown spots across the top.

Rest and garnish:

Let it sit for five minutes before serving so the sauce settles, then scatter fresh basil over the top if you have some.

There is something about pulling a bubbling dish out of the oven that makes a regular weeknight feel like an occasion worth noticing.

Making It Your Own

My sister swaps the chicken for roasted mushrooms and zucchini every time she makes this, and honestly the vegetarian version is just as satisfying. A handful of breadcrumbs scattered on top before baking adds a crunch that contrasts beautifully with the creamy sauce underneath.

What to Serve Alongside

A simple green salad with lemon vinaigrette cuts through the richness better than anything else I have tried. A glass of something crisp and cold, maybe a Pinot Grigio, turns Tuesday dinner into something that feels deliberately chosen rather than thrown together.

Storing and Reheating

Leftovers keep in an airtight container in the fridge for up to three days and reheat in the microwave without losing their charm, which makes this one of those rare bakes that actually improves overnight. The sauce thickens as it sits, so a small splash of cream or milk when reheating brings it right back to life.

• Cover the baking dish tightly with foil if you are storing the whole thing rather than individual portions.
• Freeze individual portions for up to one month, though the texture of the cream sauce changes slightly.
• Always reheat gently rather than at full power so the cheese does not separate and get oily.

This is the kind of recipe that earns a permanent spot in your rotation because it asks very little and gives back so much warmth. Share it with someone who showed up at your door hungry and let the oven do the talking.

Recipe FAQs

→ Can I use a different type of pasta?

Yes, any short tubular pasta like rigatoni, fusilli, or farfalle works well. These shapes hold the pesto cream sauce and trap bits of chicken inside, giving you a flavorful bite every time.

→ 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) until heated through.

→ Can I make this ahead of time?

Absolutely. Assemble the full 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 fridge into the oven.

→ What can I substitute for double cream?

Heavy cream works as a direct substitute. For a lighter version, you can use half-and-half or whole milk combined with a tablespoon of flour to thicken the sauce, though the result will be slightly less rich.

→ How do I get a crispier golden topping?

Sprinkle a handful of panko or regular breadcrumbs over the cheese layer before baking. You can also pop the dish under the broiler for the last 2-3 minutes, watching carefully to avoid burning.

→ Is homemade pesto better than store-bought for this dish?

Both work beautifully. Homemade basil pesto offers brighter, fresher flavor, while a good quality store-bought pesto saves time and still delivers delicious results. Choose one with real pine nuts and olive oil for the best outcome.
