Pesto Chicken Pasta Bake

The smell of basil and melted mozzarella drifting through my kitchen on a rainy Tuesday evening is what convinced me this dish deserved a permanent spot in my rotation. I had thrown it together with leftover pesto and half a pack of chicken breasts, not expecting much. The bubbling cheese blanket that emerged from the oven told a different story entirely. My partner stood in the doorway holding a fork before I even set the table.

I served this to my sister the week she moved into her new apartment with a kitchen the size of a closet. She called three days later to say she had already made it twice for herself and once for a neighbor who wandered over asking about the smell.

Ingredients

• Penne or rigatoni (350 g): Ridged pasta holds the sauce better than smooth shapes and rigatoni is especially good at trapping bits of chicken inside.
• Chicken breasts (2 boneless skinless about 300 g): Dice them small so they distribute evenly and every forkful gets a piece.
• Basil pesto (180 ml): Store bought works fine but check the ingredient list for real olive oil and actual basil rather than fillers.
• Heavy cream (150 ml) and milk (50 ml): The cream provides richness while a splash of milk keeps the sauce from turning too thick or heavy during baking.
• Mozzarella cheese (120 g shredded): Split it between mixing it in and topping the bake for cheese throughout not just on top.
• Parmesan cheese (30 g grated): This adds a salty sharp edge that mozzarella alone cannot achieve.
• Olive oil (1 tbsp): Used for searing the chicken and worth using a decent quality one.
• Salt and pepper: Season the chicken generously and taste the sauce before baking.
• Cherry tomatoes (100 g halved) and baby spinach (75 g): Optional but the tomatoes add little bursts of sweetness and the spinach melts into the sauce unnoticed.

Instructions

Get the oven hot:

Preheat to 200 degrees Celsius which is 400 Fahrenheit. You want the oven fully heated before the dish goes in so the cheese starts bubbling on contact rather than slowly warming through.

Cook the pasta just right:

Boil the penne in well salted water until just barely al dente because it will cook a little more in the oven. Drain it and shake off excess water but do not rinse it since the starch helps the sauce cling.

Sear the chicken:

Heat olive oil in a skillet over medium high heat and add the diced chicken in a single layer. Let it sit without stirring for a couple minutes so it actually browns then flip and cook until no pink remains about 6 to 7 minutes total.

Bring it all together:

In your largest bowl toss the drained pasta with the cooked chicken pesto cream milk half the mozzarella and any tomatoes or spinach you are using. Stir until the sauce coats everything evenly and tastes balanced.

Build the bake:

Transfer the entire mixture into a greased baking dish spreading it into an even layer. Scatter the remaining mozzarella over the top and finish with the grated Parmesan.

Bake until golden:

Slide it into the oven for 20 minutes or until you see the cheese bubbling and turning golden in spots. The edges should be just starting to crisp.

Rest and serve:

Let it sit for 5 minutes after removing from the oven so the sauce settles and does not run everywhere when you scoop it. Garnish with fresh basil leaves if you have them.

Save

There is something about pulling a bubbling dish from the oven that makes even a random weeknight feel like an occasion worth noticing.

When You Need Dinner Fast

A rotisserie chicken from the grocery store transforms this into a nearly hands off meal. Just shred the meat and skip the skillet entirely. You save about ten minutes and the flavor is arguably better because the roasted chicken skin adds depth.

Making It A Little Lighter

Swapping heavy cream for Greek yogurt sounds like a compromise but it actually adds a pleasant tang that pairs beautifully with the basil. Use whole milk yogurt and thin it slightly with the milk so the sauce still flows easily over the pasta.

What To Serve Alongside

A simple green salad with a sharp vinaigrette cuts through the richness of the bake and keeps the meal from feeling heavy. Crusty bread is technically unnecessary but realistically nobody is going to complain about it.

• A glass of Pinot Grigio or Sauvignon Blanc is the right call here.
• Sun dried tomatoes tossed in add a concentrated sweetness that fresh tomatoes cannot replicate.
• Always double check your pesto label for nuts if anyone has allergies because that one sneaks up on people.

Save

This is the kind of recipe that earns its place in your regular lineup by being easy enough for Tuesday and impressive enough for company. Keep pesto in your fridge and you are never more than an hour away from something wonderful.

Recipe FAQs

→ Can I use rotisserie chicken instead of raw chicken?

Yes, shredded rotisserie chicken works great and cuts down prep time significantly. Simply stir it in with the pasta and sauce before baking.

→ What type of pasta works best for this bake?

Short tubular shapes like penne or rigatoni are ideal because they hold the creamy pesto sauce well and bake evenly. Avoid long strands like spaghetti.

→ Can I make this dish ahead of time?

Absolutely. Assemble the entire bake, cover tightly, and refrigerate for up to 24 hours. Add an extra 10 minutes to the baking time if going straight from the fridge.

→ How should 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 or warm the whole dish in the oven at 180°C (350°F) until heated through.

→ Can I freeze pesto chicken pasta bake?

Yes, you can freeze it before or after baking. Wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge before baking or reheating.

→ What can I substitute for heavy cream?

Light cream, half-and-half, or Greek yogurt thinned with a little milk all work as lighter alternatives. Keep in mind the sauce may be slightly less rich.
