Creamy Pesto Chicken Pasta Bake
Equipment
- 9×13 inch baking dish
- Large pot
- Large skillet
- Colander
- Wooden spoon or spatula
- Chef’s knife and cutting board
Ingredients
Pasta & Chicken
- 10.5 oz Penne or rigatoni pasta
- 2 medium Boneless, skinless chicken breasts, diced about 10.5 oz total
- 1 tbsp Olive oil
- Salt and freshly ground black pepper to taste
Creamy Pesto Sauce
- 1 tbsp Unsalted butter
- 2 cloves Garlic minced
- ¾ cup + 2 tbsp Heavy cream
- ½ cup Whole milk
- ½ cup Basil pesto store-bought or homemade
- ¾ cup Parmesan cheese grated
- 3.5 oz Baby spinach optional, for extra nutrition
Topping
- 1 cup Mozzarella cheese shredded
- ¼ cup Parmesan cheese grated
Instructions
- Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish and set aside.
- Bring a large pot of well-salted water to a boil. Cook the pasta for 2 minutes less than the package directions — it should be just under al dente. Drain and set aside. It will finish cooking in the oven.
- Heat 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.
- In the same skillet over medium heat, melt the butter. Add the minced garlic and sauté for 30 seconds until fragrant. Pour in the heavy cream and whole milk, then bring to a gentle simmer for 2–3 minutes until slightly thickened. Stir in the basil pesto and grated Parmesan until the sauce is smooth and silky.
- Add the cooked chicken, drained pasta, and baby spinach (if using) to the sauce. Toss everything together until evenly coated and the spinach has wilted slightly.
- Transfer the pasta mixture into the prepared baking dish and spread it out evenly. Sprinkle the shredded mozzarella and extra Parmesan cheese evenly over the top.
- Bake uncovered for 20–25 minutes, until the cheese is golden and bubbling. For extra browning, switch to broil for the last 2–3 minutes — watch it closely!
- Remove from the oven and let the dish rest for 5 minutes before serving. This helps the sauce settle and makes it much easier to scoop and serve.

A quick note on the pesto: store-bought works great here, but if you’ve got a blender and some fresh basil, homemade pesto takes this over the top. Either way, you’re winning.
Step-by-Step Instructions
Step 1: Preheat and Prep
Get your oven going at 400°F (200°C) and lightly grease a 9×13-inch baking dish. This is the moment where you also want to dice your chicken if you haven’t already — bite-sized pieces cook faster and give you more of that golden crust on every piece.
Step 2: Cook the Pasta (But Not All the Way)
Boil your pasta in well-salted water, but pull it out 2 minutes before the package says it’s done. It should still have a firm bite — almost al dente but not quite. It’ll finish cooking in the oven, so if you cook it all the way now, you’ll end up with mushy pasta. Nobody wants that.
💡 Tip: Salt your pasta water generously — it should “taste like the sea.” This is the only chance you have to season the pasta itself.
Step 3: Sauté the Chicken
Heat olive oil in a large skillet over medium-high. Season your diced chicken with salt and pepper, then let it sauté for about 5–6 minutes until cooked through and lightly golden. You want a little color on the outside — that golden crust adds so much flavor. Once it’s done, pull it off the heat and set it aside.
This step is also what keeps this recipe feeling like a proper dinner and not just “pasta in sauce.” The chicken adds substance and makes this one of the most satisfying easy big family meals in my lineup.
Step 4: Build the Creamy Pesto Sauce
In the same skillet (don’t wash it — those chicken bits = flavor), melt your butter over medium heat. Add the minced garlic and let it sizzle for about 30 seconds. You want it fragrant but not burnt — burnt garlic is a one-way ticket to bitter town.
Next, pour in the heavy cream and whole milk and bring it to a gentle simmer for 2–3 minutes. It’ll thicken slightly. Then stir in your basil pesto and Parmesan cheese until the sauce is smooth, silky, and smells absolutely incredible.

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 it’s all evenly coated and the spinach wilts down a bit. The whole mixture should look creamy, glossy, and deeply green-flecked. It already smells like dinner.
The spinach is optional but I really recommend it — it adds nutrition, a little color, and you genuinely cannot taste it. If you’ve got picky eaters at home, this is a sneaky win. (You can also try this trick in these easy spinach garlic meatballs — same idea, different dish.)
Step 6: Assemble and Top
Pour the whole gorgeous mixture into your greased baking dish and spread it out evenly. Then rain down that shredded mozzarella and extra Parmesan on top. Don’t be shy — this is the moment where generosity is rewarded.
Step 7: Bake Until Golden and Bubbly
Slide it into the oven uncovered and bake for 20–25 minutes. You’re looking for a top that’s golden, bubbly, and slightly crispy around the edges. If your oven runs cool, give it an extra 5 minutes. You’ll know it’s done when the whole kitchen smells like a cheesy basil dream.
Step 8: Rest Before Serving
Let the dish rest for 5 minutes before you dig in. I know. It’s hard. But the sauce will settle and thicken slightly, making it so much easier to serve — and even more delicious to eat.
Expert Tips, Variations & Troubleshooting
Pro Tips for the Best Result
Don’t skip the undercooking step. Pulling the pasta 2 minutes early is the difference between a creamy pasta bake and a dry, starchy mess. Pasta always keeps cooking in the oven.
Season in layers. Salt the pasta water, season the chicken, and taste the sauce before assembling. Pesto brands vary wildly in saltiness, so always taste before adding extra salt.
Use full-fat dairy. Whole milk and heavy cream give you that rich, velvety sauce. Low-fat versions can cause the sauce to split or turn watery. This isn’t the recipe to go light on — treat yourself.
Fun Variations to Try
- Sun-dried tomato twist: Stir in ½ cup of chopped sun-dried tomatoes when combining the pasta and sauce. It adds a chewy, tangy depth that plays beautifully with the pesto.
- Swap the protein: This works great with shrimp, Italian sausage, or even rotisserie chicken if you want to save time. On busy nights, I often use pre-cooked chicken — it’s one of the easiest shortcut moves for quick easy healthy pasta dinner recipes.
- Make it vegetarian: Skip the chicken entirely and double up on the spinach, or add roasted zucchini and cherry tomatoes. Still delicious, still filling.
- Add a crunchy topping: Mix breadcrumbs with a drizzle of olive oil and scatter them over the cheese before baking. Adds texture and makes it feel extra fancy for zero extra effort.

Troubleshooting
Sauce too thick? Add a splash of pasta water or milk when combining — it loosens right up.
Cheese not browning? Crank the oven to broil for the last 2–3 minutes. Just watch it closely because it goes from “golden” to “charcoal” faster than you’d expect.
Too salty? Taste your pesto before using. Some store-bought brands are saltier than others, so you may want to cut back on added salt.
Storage Instructions
| Method | Container | Duration |
|---|---|---|
| Refrigerator | Airtight container | Up to 4 days |
| Freezer | Freezer-safe container | Up to 2 months |
| Room Temperature | Not recommended | Max 2 hours |
Reheating Tips
From the fridge: Add a splash of milk or cream to keep things saucy, then reheat covered with foil at 350°F for about 15–20 minutes. Or microwave in 60-second bursts, stirring between each.
From frozen: Thaw overnight in the fridge, then reheat as above. If it looks a little dry, a spoonful of pesto stirred in revives it instantly.
No-Waste Kitchen Ideas
Leftover pasta bake makes an incredible next-day lunch. Scoop individual portions into meal-prep containers — it actually reheats better than you’d expect. Got extra pesto? Smear it on toast, toss it with roasted veggies, or use it as a dipping sauce. Nothing goes to waste here.

Creamy Pesto Chicken Pasta Bake FAQs
Can I make this creamy pesto chicken pasta bake ahead of time?
Absolutely! Assemble everything up through Step 6, cover tightly with plastic wrap or foil, and refrigerate for up to 24 hours. When you’re ready, uncover and bake as directed — you may need to add an extra 5 minutes since it’s going in cold. It’s a lifesaver for easy big family meals on busy nights.
Can I use a different type of pasta?
Yes! Penne and rigatoni are great because their ridges and tubes hold the creamy sauce, but ziti, rotini, or farfalle all work well here. Just avoid very small pasta shapes like orzo — they tend to get lost in the sauce.
What kind of pesto should I use?
Store-bought basil pesto is totally fine and makes this a quick weeknight win. If you want to go homemade, a classic basil-Parmesan pesto is ideal. You could also experiment with sun-dried tomato pesto or spinach pesto for a fun twist on these meals with pesto sauce.
Can I make this gluten-free?
Yes! Just swap the pasta for your favorite gluten-free variety. The sauce itself is naturally gluten-free, so no other adjustments are needed. Cook the GF pasta 3–4 minutes less than directed, as it tends to get softer during baking.
Is this recipe freezer-friendly?
It freezes well! Let it cool completely, then portion into freezer-safe containers. Freeze for up to 2 months. Thaw overnight in the fridge and reheat with a splash of milk to bring the creaminess back to life.
