Step-by-Step Instructions
Step 1 — Preheat and Prep
Start by preheating your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish and set it aside. This is the “while you’re at it” step — get this done first so you’re not scrambling later.
Step 2 — Undercook the Pasta (Yes, On Purpose)
Bring a large pot of well-salted water to a boil and cook your penne or rigatoni for 2 minutes less than the package says. You want it just under al dente — it’ll finish cooking in the oven and soak up all that gorgeous pesto cream sauce. Drain it and set it aside.
Tip: Salting your pasta water generously is one of those tiny things that makes a noticeable difference in the final flavor. Don’t skip it!
Step 3 — Sauté the Chicken
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season your diced chicken with salt and pepper, then sauté for about 5–6 minutes until cooked through and lightly golden on the edges. That golden color = flavor. Remove the chicken from the heat and set aside — but don’t wash that skillet. You’re going to use it for the sauce and all those browned bits are basically free seasoning.
Step 4 — Build the Creamy Pesto Sauce
In the same skillet, melt 1 tablespoon of butter over medium heat. Add your minced garlic and let it sauté for about 30 seconds — just until fragrant. Your kitchen should smell amazing right about now.
Pour in the heavy cream and whole milk, stirring gently. Let the mixture come to a gentle simmer and cook for 2–3 minutes until it thickens slightly. Then stir in the basil pesto and grated Parmesan until it all melts together into a smooth, glossy sauce. This is what makes it one of the best meals with pesto sauce — that creamy, herb-forward base is absolutely dreamy.
“The smell of garlic hitting butter is honestly one of the best things in cooking. Take a second to appreciate it.”
Step 5 — Combine Everything
Add the cooked chicken, drained pasta, and spinach (if using) back into the skillet with the sauce. Toss everything together until every piece of pasta is coated in that creamy pesto goodness. If the sauce feels a bit thick, a splash of pasta water loosens it up perfectly.
Step 6 — Assemble and Top
Transfer your saucy pasta mixture into the prepared baking dish and spread it out evenly. Sprinkle the shredded mozzarella and extra Parmesan generously over the top. Don’t be shy — this is the part that turns into that irresistible golden crust.
Step 7 — Bake Until Golden and Bubbly
Pop the dish into the oven, uncovered, and bake for 20–25 minutes. You’re looking for the cheese to be golden, bubbly, and slightly browned at the edges. If you want even more color on top, hit it with the broiler for the last 2 minutes — just keep a close eye on it!
Step 8 — Rest Before Serving
Let the bake rest for 5 minutes before you dig in. I know. It smells incredible. But those 5 minutes help the sauce settle so it’s creamy and scoopable rather than running all over the plate. Patience pays off here.
Expert Tips, Variations & Troubleshooting
Tips for the Best Result
Always undercook your pasta before baking — this is the single most important rule for avoiding mushy pasta bakes. If it’s fully cooked before it goes in the oven, it’ll be overdone by the time the cheese is golden.
For the best creamy pesto chicken pasta bake flavor, use a good-quality basil pesto. Store-bought works great (Aldi’s is surprisingly excellent), but if you want to go homemade, the difference is definitely noticeable. You can also try this high-protein dip as a starter alongside it — great for entertaining!
Tasty Variations
Want to make it a proper white chicken pasta bake with a sun-dried tomato twist? Stir in ¼ cup of chopped sun-dried tomatoes with the sauce — it adds a tangy depth that works beautifully with the pesto. You can also swap the chicken for shrimp or even roasted vegetables to make it vegetarian.
Trying to keep things lighter? Sub half the heavy cream for more whole milk, and use a lighter pesto. It won’t be quite as rich, but it still delivers seriously good flavor, and it fits more comfortably into your easy healthy pasta dinner recipes rotation.
Troubleshooting
Sauce too thick? Add a splash of pasta water or extra milk before baking and toss to loosen.
Cheese not browning? Broil for 2–3 minutes at the end. Watch it carefully — it goes from perfect to burnt fast.
Pasta too dry after baking? This usually means the pasta was overcooked before baking, or the dish spent too long in the oven. Next time, pull it a minute or two earlier and add a little extra sauce before topping with cheese.
Storage Instructions
| Method | Container | Duration |
|---|---|---|
| Refrigerator | Airtight container | Up to 4 days |
| Freezer | Freezer-safe container or wrapped dish | Up to 2 months |
Reheating
For the best results, reheat leftovers in the oven at 350°F (175°C) covered with foil for about 15 minutes, or until warmed through. The microwave works in a pinch — just add a small splash of milk or cream before heating to revive the sauce and keep it creamy rather than gloopy.
No-Waste Kitchen Ideas
Got leftover baked pasta? Stir it into a skillet with a little cream or broth, reheat gently, and it eats like a whole new meal. You can also chop it up and serve it over salad greens for a hearty lunch — pair it alongside something fresh like this chickpea feta avocado salad for a complete, satisfying meal.

Frequently Asked Questions
Can I make this creamy pesto chicken pasta bake ahead of time?
Yes! Assemble the whole dish — pasta, chicken, sauce, and even the cheese topping — then cover and refrigerate for up to 24 hours before baking. When you’re ready, just pop it straight from the fridge into the oven and add an extra 5–8 minutes to the bake time.
It’s one of the reasons this works so well for meal prep and dinner parties.
What’s the best pasta shape to use?
Penne and rigatoni are the top picks here because their tubular shape traps the creamy pesto sauce inside each piece — which is kind of the whole point, right? You can also use fusilli or farfalle if that’s what you have on hand. Just avoid thin pasta like spaghetti or angel hair — they don’t hold up well in a bake.
Can I use jarred store-bought pesto for this meals with pesto sauce recipe?
Absolutely, and there’s zero shame in it. A good-quality store-bought basil pesto works beautifully and keeps this in the easy weeknight dinner category. If you have homemade pesto on hand, even better — it’ll have a brighter, fresher flavor. Either way, you’re getting a delicious result.
Is this recipe freezer-friendly?
It is! Let it cool completely, then wrap the dish tightly in plastic wrap followed by foil, or portion it into freezer-safe containers. It keeps well for up to 2 months. Thaw overnight in the fridge before reheating in the oven at 350°F until warmed through. The texture is best when reheated in the oven rather than the microwave for a frozen portion.
What can I serve with this white chicken pasta bake?
A simple green salad or some garlic bread are the classic go-tos — and honestly, they’re classics for a reason. For a more protein-packed pairing, try this cottage cheese chicken salad on the side. Or if you’re looking for something lighter to start, a small bowl of this oats khichdi works as a cozy side that balances the richness of the bake.

- 1 tablespoon unsalted butter
- 2 cloves garlic, minced
- 0.875 cup heavy cream ¾ cup plus 2 tablespoons
- 0.5 cup whole milk
- 0.5 cup basil pesto store-bought or homemade
- 0.75 cup grated Parmesan cheese
- 3.5 oz baby spinach optional, for extra nutrition
Topping
- 1 cup shredded mozzarella cheese
- 0.25 cup grated Parmesan cheese
Instructions
- Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish and set it aside.
- Bring a large pot of generously salted water to a boil. Cook the penne or rigatoni for 2 minutes less than the package directions — you want it just under al dente. Drain and set aside.
- Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the diced chicken with salt and pepper, then sauté for 5–6 minutes until cooked through and lightly golden. Remove from heat and set aside. Do not wash the skillet.
- In the same skillet, melt the butter over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant. Pour in the heavy cream and whole milk, stirring gently. Bring to a gentle simmer and cook for 2–3 minutes until slightly thickened. Stir in the basil pesto and grated Parmesan until smooth and glossy.
- Return the cooked chicken, drained pasta, and baby spinach (if using) to the skillet. Toss everything together until evenly coated in the creamy pesto sauce. If the sauce feels too thick, add a splash of reserved pasta water to loosen.
- Transfer the pasta mixture into the prepared baking dish and spread evenly. Sprinkle the shredded mozzarella and extra Parmesan generously over the top.
- Bake uncovered for 20–25 minutes until the cheese is golden, bubbly, and slightly browned at the edges. For extra color, broil for the final 2 minutes — watch it closely.
- Remove from the oven and let the bake rest for 5 minutes before serving. This helps the sauce settle so it’s creamy and scoopable rather than runny.
