Pesto Chicken Pasta Bake

The oven had barely stopped clicking from preheating when my youngest wandered in, drawn by the smell of basil and garlic like a moth to flame. Pesto chicken pasta bake is one of those dishes that turns a regular Tuesday into something worth sitting down for, forks in hand, nobody checking their phone. The cheese pulls are obscene, the sauce clings to every ridged noodle, and it reheats beautifully for lunch the next day.

One rainy Saturday I made this for my 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. That note is still stuck to my fridge with a magnet shaped like a lemon.

Ingredients

• 300 g penne or rigatoni: Ridged pasta holds the sauce better than smooth shapes, so pick one with texture.
• 2 boneless skinless chicken breasts (about 350 g): Cut them into uniform bite sized pieces so everything cooks evenly without drying out.
• 1 tbsp olive oil: Just enough to get a good sear on the chicken without making it greasy.
• 1/2 tsp salt and 1/4 tsp black pepper: Seasoning the chicken directly builds flavor from the ground up.
• 120 g basil pesto: Store bought works beautifully, but if you have a jar of homemade in the freezer, now is its moment to shine.
• 150 ml double cream or heavy cream: This is what transforms pesto from a condiment into a luxurious sauce that blankets everything.
• 2 cloves garlic, minced: Fresh garlic smashed and minced right before using gives the most pungent, sweet result.
• 50 g sun dried tomatoes, chopped: Optional but they add little bursts of tangy sweetness that break up the richness perfectly.
• 100 g shredded mozzarella: The melt factor here is nonnegotiable, so use low moisture mozzarella, not fresh.
• 40 g grated Parmesan cheese: Grate it yourself from a wedge for the best texture and flavor that actually melts.
• Fresh basil leaves: Torn over the top at the last second for color and a hit of fresh aroma.

Instructions

Get the oven hot and ready:

Preheat your oven to 200 degrees Celsius (400 degrees Fahrenheit) and lightly grease a large baking dish with a swipe of butter or oil so nothing sticks later.

Boil the pasta to just underdone:

Cook the pasta in well salted boiling water until just al dente, meaning it still has a slight bite, because it will finish cooking in the oven and you do not want mush.

Sear the chicken golden:

Heat olive oil in a large skillet over medium heat, add the seasoned chicken pieces, and let them sit undisturbed for a minute so they actually brown before you stir, cooking five to six minutes total until no longer pink inside.

Bring everything together:

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

Build the bake:

Transfer the whole mixture into your prepared baking dish, spreading it out evenly, then shower the top generously with mozzarella and Parmesan so every bite gets a piece of that golden crust.

Bake until bubbling and proud:

Slide it into the oven for about twenty minutes until the cheese is melted, bubbling at the edges, and speckled with golden brown spots that make everyone hovering nearby unable to resist.

Rest and garnish:

Let it sit for five minutes before serving so the sauce thickens slightly and does not run everywhere, then scatter torn basil leaves over the top and bring it to the table.

Save

There is something about carrying a bubbling dish from oven to table that makes everyone in the house appear without being called.

Making It Your Own

Swap the chicken for roasted zucchini, bell peppers, and mushrooms if you want a vegetarian version that still feels hearty and complete. A handful of breadcrumbs tossed with olive oil and scattered on top before baking adds a crunch that contrasts beautifully with the creamy sauce underneath.

What to Serve Alongside

A simple arugula salad with lemon juice and olive oil cuts through the richness of this bake perfectly. A chilled glass of Sauvignon Blanc or Pinot Grigio beside it turns a weeknight dinner into something that feels intentional and special.

Storing and Reheating

This bake keeps well in the refrigerator for up to three days when covered tightly with foil or transferred to an airtight container. For meal prep, portion it into individual containers so you can grab and reheat throughout the week without any fuss.

• Reheat in the oven at 180 degrees Celsius (350 degrees Fahrenheit) for about fifteen minutes to bring back the crispy cheese top.
• A microwave works for quick lunches but cover the dish to prevent the pasta from drying out.
• Freeze individual portions for up to one month, though the cream sauce may separate slightly when thawed.

Save

Some dinners are about nourishment and some are about gathering, and this dish manages to be both without asking much of you at all.

Recipe FAQs

→ Can I use a different type of pasta?

Yes, any short pasta shape like fusilli, farfalle, or cavatappi works well. Choose shapes with ridges or curves that hold onto the creamy pesto sauce for the best result.

→ 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 cover the baking dish with foil and warm in a 180°C (350°F) oven for about 15 minutes until heated through.

→ 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 fridge into the oven.

→ What can I substitute for double cream?

Heavy cream is a direct equivalent. For a lighter option, use half-and-half or a mix of whole milk with a tablespoon of cornstarch. The sauce will be slightly less rich but still delicious.

→ How do I make this dish vegetarian?

Replace the chicken with a mix of roasted vegetables like zucchini, bell peppers, and mushrooms. Sauté them until golden before combining with the pasta and pesto cream sauce. The baking time remains the same.

→ Can I freeze pesto chicken pasta bake?

Yes, you can freeze it before or after baking. Wrap the dish tightly in foil and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. Note that the cream sauce may separate slightly upon thawing but will come together when reheated.
