Pesto Chicken Pasta Bake

The smell of bubbling cheese and pesto always pulls everyone into the kitchen before dinner is even ready. My youngest started calling this green mac and cheese years ago, and the nickname stuck. There is something about the way the pesto infuses every single pasta bend that makes it impossible to stop at one serving.

I first threw this together on a frantic Tuesday when rotisserie chicken felt like cheating but desperation won. My husband took one bite and asked what restaurant it came from. Now it is our go-to when we want comfort food without the heaviness of traditional cream sauces.

Ingredients

• Penne or rigatoni: These shapes capture the pesto sauce in their ridges and tubes, giving you flavor in every single bite
• Chicken breasts: Dicing them small means they cook quickly and distribute evenly throughout the dish
• Basil pesto: Homemade adds brightness, but good store-bought works perfectly for weeknights when time is tight
• Tomato passata: This creates a silky base that mellows the sharpness of the pesto just enough
• Mozzarella: Shredded yourself melts better than pre-shredded, which has anti-caking agents
• Parmesan: Adds that salty umami punch that makes the whole dish taste restaurant-quality
• Garlic: Freshly minced blooms in the olive oil and infuses the entire chicken mixture

Instructions

Get your oven ready:

Preheat to 200°C (390°F) so it is piping hot and ready to work its magic on that cheese.

Cook the pasta:

Boil the penne in salted water until just al dente, as it will continue cooking in the oven.

Sauté the chicken:

Cook the diced chicken in olive oil until golden and cooked through, then add garlic for just one minute.

Build the sauce:

Stir in the tomato passata and half the pesto, letting it simmer together briefly.

Combine everything:

Mix the pasta with the chicken sauce, remaining pesto, and half the mozzarella in a large bowl.

Assemble the bake:

Transfer to a baking dish and top with the remaining mozzarella and Parmesan.

Bake to perfection:

Bake for 20 minutes until the cheese is golden and bubbling, then let it rest for 5 minutes.

Save

This recipe became a regular at our monthly family dinners after my sister requested it for her birthday. Now nobody asks what we are having anymore. They just show up with their own containers, knowing there will be plenty to go around.

Make It Your Own

Sun-dried tomatoes tucked between layers add chewy bursts of concentrated flavor. Sometimes I add spinach if I need to sneak in greens, wilting it right into the sauce before combining with the pasta.

Shortcuts That Work

Rotisserie chicken shreds beautifully and cuts the cooking time in half. I keep frozen pesto cubes in the freezer for those nights when even opening a jar feels like too much effort.

Serving Suggestions

A crisp white wine cuts through the richness perfectly. Simple garlic bread or a green salad with vinaigrette balances the heaviness of the baked pasta.

• Pinot Grigio or Sauvignon Blanc both pair beautifully
• A arugula salad with lemon dressing brightens the meal
• Save some fresh basil for the final garnish to pop against the melted cheese

There is nothing quite like pulling this bubbling dish out of the oven and watching everyone gather around. Hope it becomes a favorite in your house too.

Recipe FAQ

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

Absolutely. Store-bought basil pesto works perfectly and saves time. Look for quality brands with fresh basil and check the ingredients for any allergens, particularly tree nuts if you have sensitivities.

→ What pasta shapes work best for this dish?

Penne and rigatoni are ideal because their tubes and ridges capture the pesto sauce beautifully. You can also use fusilli or farfalle. Avoid delicate shapes like angel hair, which may become mushy during baking.

→ How can I make this dish gluten-free?

Simply substitute regular pasta with gluten-free penne or rigatoni. The cooking time remains the same. Ensure your pesto and marinara sauce are certified gluten-free, and verify all other ingredients for hidden gluten.

→ Can I prepare this ahead of time?

Yes, you can assemble the casserole up to 24 hours in advance. Cover and refrigerate, then bake when ready. Add 5-10 minutes to the baking time if cooking from cold. This makes it perfect for meal planning.

→ What vegetables can I add for extra nutrition?

Sun-dried tomatoes, roasted zucchini, bell peppers, spinach, or mushrooms complement the pesto flavors beautifully. Add raw vegetables in the last layer before cheese to maintain their texture, or sauté them first for deeper flavor.

→ Is rotisserie chicken a good substitute?

Yes, rotisserie chicken is an excellent time-saver. Shred or dice about 2 cups of cooked meat and skip the initial cooking step. This reduces active cooking time significantly while maintaining excellent flavor and texture.
