Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Prepare Baking Dish and Preheat Oven
Begin by preheating your oven to 400°F (200°C). While it warms, grease a 9×13-inch baking dish with a bit of butter or oil to prevent sticking. This step is crucial, as it ensures your Creamy Pesto Chicken Pasta Bake releases easily after baking and presents beautifully when served.
Step 2: Cook Pasta
Bring a large pot of salted water to a boil and add your choice of pasta—penne, rigatoni, or gluten-free. Cook it for 2 minutes less than recommended on the package, so it’s just under al dente. This slight undercooking is vital as it will absorb the creamy sauce during baking, creating the perfect texture.
Step 3: Sauté Chicken
In a skillet, heat a drizzle of olive oil over medium-high heat. Season your chicken with salt and pepper, then add it to the skillet. Sauté the chicken for about 5-6 minutes until it’s golden brown and cooked through, stirring occasionally. The delicious aroma will fill your kitchen as the chicken browns, ready to add heartiness to your pasta bake.
Step 4: Make Creamy Pesto Sauce
Using the same skillet, add a tablespoon of butter and melt it over medium heat. Once melted, add minced garlic and sauté for about a minute until fragrant. Then, pour in the heavy cream and whole milk, allowing it to simmer for 2-3 minutes. Stir in the basil pesto and grated Parmesan, mixing until you achieve a smooth, creamy sauce that will envelop your pasta beautifully.
Step 5: Combine Ingredients
Return the cooked chicken to the skillet with the creamy pesto sauce, allowing the flavors to meld for a minute. Next, drain your pasta and add it to the skillet, tossing everything together until well coated. If you’re opting for spinach, fold it in now, letting it wilt slightly into the creamy mix, enhancing both flavor and nutrition.
Step 6: Assemble and Top
Transfer the creamy pasta mixture into your greased baking dish, spreading it out evenly. Generously sprinkle mozzarella cheese and extra Parmesan over the top. This cheesy layer will create that desired golden, bubbly crust once baked and provide irresistible gooeyness to every bite of your Creamy Pesto Chicken Pasta Bake.
Step 7: Bake
Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. Keep an eye on the dish; you’re looking for the cheese to become bubbly and golden brown. The visual cue of that lovely golden top signals that dinner time is near, and it’s going to be delicious!
Step 8: Rest and Serve
Once baking is complete, carefully remove the dish from the oven and let it rest for about 5 minutes. This resting period helps the layers settle, making serving easier and enhancing the texture of your Creamy Pesto Chicken Pasta Bake. Enjoy this comforting dish with a fresh green salad or garlic bread for a complete meal!

Creamy Pesto Chicken Pasta Bake Recipe FAQs
How do I choose ripe ingredients for this dish?
Absolutely! For optimal flavor, select fresh, vibrant basil for your pesto and look for firm, plump chicken breasts without any dark spots. If you’re opting for spinach, choose dark, leafy greens that are not wilted, and if using mushrooms, pick those that are firm and have no signs of moisture. Fresh mozzarella should be soft and creamy, with no unusual smells.
How should I store leftover Creamy Pesto Chicken Pasta Bake?
Store any leftovers in an airtight container in the fridge for up to 4 days. When you’re ready to reheat, simply pop it in the microwave or oven until warmed through. If you notice the dish looking a little dry, add a splash of cream or milk while reheating to bring back its creamy texture.
Can I freeze the Creamy Pesto Chicken Pasta Bake?
Very much! Assemble your pasta bake as directed, but instead of baking, cover it tightly with foil and freeze for up to 3 months. When you’re ready to enjoy, you can bake it directly from frozen—just be prepared to increase the cooking time by about 10-15 minutes to ensure it heats through evenly.
What should I do if my pasta bake seems too dry?
If your dish looks dry after baking, don’t worry! Simply add a little more cream before serving, as the pasta can absorb moisture during baking. If you’ve already baked it, you can mix in a bit of milk or cream when reheating for that rich, creamy consistency.
Are there any dietary considerations for this dish?
Yes! For those with gluten sensitivities, you can easily substitute regular pasta with gluten-free options. If you’re catering to vegetarians, simply omit the chicken and increase the amount of spinach or add sautéed mushrooms instead. Also, do check your pesto ingredients to ensure it’s free from nuts if there are nut allergies.
How do I know when my pasta bake is done?
Look for the cheese to be golden and bubbly, typically around 20-25 minutes at 400°F (200°C). The visual cue of a bubbly, golden top signifies deliciousness is near! If you’d like to ensure it’s cooked through, use a food thermometer—145°F (63°C) for chicken is the safe zone.
