Pesto Chicken Pasta Bake

The smell of pesto hitting a hot skillet is one of those things that stops me in my tracks every single time, basil and garlic blooming into something almost ridiculously fragrant. I started making this pasta bake on rainy Tuesday nights when cooking felt like a chore but eating well still mattered. It turned a boring evening into something worth sitting down for. Now it shows up on my table at least twice a month, no matter the season.

My neighbor walked in once while I was pulling this from the oven and declared it smelled like an Italian grandmother had taken over my kitchen. We stood over the baking dish with two forks before it even cooled properly, burning our tongues and not caring one bit.

Ingredients

• Penne or rigatoni (300 g): The ridges on rigatoni catch the pesto cream sauce beautifully, so if you can find it, grab rigatoni over smooth pasta shapes.
• Boneless skinless chicken breasts (2, about 350 g): Cut them into uniform bite sized pieces so everything cooks evenly without drying out.
• Olive oil (1 tbsp): Just enough to get a golden sear on the chicken, nothing more.
• Salt and black pepper: Season the chicken boldly here because the pasta and cream will mellow everything out.
• Basil pesto (120 g, about 1/2 cup): Homemade pesto is lovely but a good store bought version works perfectly when you are short on time.
• Double cream or heavy cream (150 ml): This is what turns a basic pesto pasta into something rich and bake worthy.
• Garlic, minced (2 cloves): Fresh garlic mixed raw into the sauce gives a gentle bite that mellows during baking.
• Sun dried tomatoes, chopped (50 g, optional): They add little hits of tangy sweetness scattered through each bite.
• Shredded mozzarella (100 g): The melting cheese that makes the top bubbly and irresistible.
• Grated Parmesan (40 g): Mixed with the mozzarella for a salty, golden crust.
• Fresh basil leaves (for garnish): Torn over the top at the last second for color and a hit of fresh flavor.

Instructions

Get the oven hot:

Preheat your oven to 200 degrees C (400 degrees F) and lightly grease a large baking dish with a bit of olive oil or butter so nothing sticks.

Cook the pasta al dente:

Boil the pasta in well salted water until just barely al dente, since it will cook a little more in the oven and you want it to hold its shape.

Sear the chicken:

Heat olive oil in a large skillet over medium heat, add the seasoned chicken pieces, and cook for 5 to 6 minutes until golden on the outside and cooked through inside.

Bring it all together:

In a large mixing bowl, toss the drained pasta with the chicken, pesto, cream, minced garlic, and sun dried tomatoes until every piece is coated in that green, creamy sauce.

Build the bake:

Transfer everything into your prepared baking dish, spreading it out evenly, then shower the top generously with mozzarella and Parmesan.

Bake until golden:

Slide it into the oven for about 20 minutes until the edges are bubbling and the cheese has turned a gorgeous golden brown.

Rest and garnish:

Let it sit for 5 minutes so the sauce settles, then scatter torn basil leaves over the top and serve directly from the dish.

There was a Sunday when I made this for a friend who had just gone through a rough breakup, and she sat cross legged on my kitchen floor eating a second helping straight from the dish. She said it was the first thing that had tasted good in weeks.

Serving Ideas That Actually Work

A simple arugula salad with lemon juice and olive oil cuts through the richness of this bake perfectly. If you want something warm on the side, roasted broccoli with a squeeze of lemon does the same job with a bit more heft. A glass of cold Pinot Grigio beside it never hurt anyone either.

Making It Your Own

This recipe bends easily in whatever direction your fridge points you. Swap the chicken for sauteed mushrooms, zucchini, and roasted red peppers and you have a completely vegetarian dinner that tastes just as celebratory. A handful of breadcrumbs tossed with olive oil and scattered over the cheese before baking adds a crunchy lid that makes each spoonful more interesting. You could even stir in a spoonful of ricotta for pockets of creamy surprise throughout.

Storage and Reheating

Cover the baking dish tightly with foil and it keeps well in the fridge for up to three days, though in my experience it never lasts that long. Reheat individual portions in the microwave for about 90 seconds, or warm the whole dish covered in a 180 degree C (350 degree F) oven until bubbling again.

• Freeze individual portions wrapped tightly in foil for up to one month, then thaw overnight in the fridge before reheating.
• If the top looks dry after reheating, scatter a small handful of fresh mozzarella and run it under the broiler for two minutes.
• Always check that the center is piping hot before serving, since baked pasta holds its heat stubbornly in the middle.

This is the kind of dish that reminds you comfort food does not need to be complicated to be memorable. Just pesto, cream, cheese, and a hot oven can turn an ordinary weeknight into something you actually look forward to.

Your Recipe Questions Answered

→ Can I make pesto chicken pasta bake ahead of time?

Yes, you can assemble the entire dish up to 24 hours in advance. Cover it tightly and refrigerate, then bake at 200°C (400°F) for 25–30 minutes until golden and bubbling throughout.

→ What type of pasta works best for this bake?

Short, sturdy shapes like penne, rigatoni, or fusilli are ideal. Their tubular structure holds the creamy pesto sauce well and stands up to baking without becoming mushy.

→ Can I use homemade pesto instead of store-bought?

Absolutely. Homemade basil pesto will elevate the flavor even further. Use about 120 g (roughly 1/2 cup) for this quantity. Classic basil, pine nut, garlic, and Parmesan pesto works beautifully.

→ 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.

→ Can I freeze pesto chicken pasta bake?

Yes, it freezes well. Assemble the dish but hold off on the cheese topping. Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge, add the cheese, and bake as directed.

→ What can I substitute for double cream?

Heavy cream works as a direct substitute. For a lighter option, use half-and-half or a mixture of whole milk with a tablespoon of cornstarch to maintain some richness and body in the sauce.
