Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Cook the Pasta
Bring a large pot of salted water to a rolling boil over high heat. Once boiling, add the 12 ounces of penne pasta and cook according to package instructions until al dente, approximately 10-12 minutes. Drain the pasta and set it aside, allowing the steam to escape, which will prevent it from becoming mushy later in the Creamy Pesto Chicken Pasta Bake.
Step 2: Sauté the Chicken
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add in the pound of diced chicken, seasoning it generously with 1 teaspoon of salt and 1 teaspoon of pepper. Cook the chicken for about 6-8 minutes, turning occasionally until it’s nicely browned and cooked through. Once done, remove the chicken from the skillet and set it aside, letting the flavors settle.
Step 3: Wilt the Spinach
Using the same skillet, add 3 cups of fresh spinach. Sauté the spinach over medium heat for 2-3 minutes, stirring occasionally until it’s wilted and vibrant in color. This step not only adds nutrients to your Creamy Pesto Chicken Pasta Bake but also elevates its visual appeal, creating a deliciously inviting dish.
Step 4: Combine the Sauce Ingredients
In a large mixing bowl, combine 1 cup of basil pesto with 1 cup of heavy cream, stirring until well-mixed and creamy. Once your sauce is ready, fold in the sautéed spinach, the cooked chicken, the penne pasta, and half of the 1 cup of shredded mozzarella cheese. This mixture will be the heartbeat of your Creamy Pesto Chicken Pasta Bake, binding all flavors together.
Step 5: Prepare for Baking
Preheat your oven to 350°F (175°C) to ensure it’s hot and ready when you’re done mixing. While the oven heats, transfer your creamy pasta mixture into a greased baking dish, spreading it out evenly. Top it with the remaining mozzarella cheese and ½ cup of grated Parmesan cheese, creating a gooey, cheesy layer that's hard to resist.
Step 6: Bake the Dish
Place the baking dish in the preheated oven and bake for 20-25 minutes. Keep an eye on it as the cheese melts and becomes bubbly and golden. You’ll know your Creamy Pesto Chicken Pasta Bake is ready when it’s beautifully browned on top and the aroma fills your kitchen, beckoning everyone to the table.

Creamy Pesto Chicken Pasta Bake Recipe FAQs
How do I select the best basil pesto for this recipe?
Absolutely! Look for basil pesto that is bright green and has a fresh, aromatic smell. Avoid jars that contain dark spots or have been sitting on the shelf for a long time. If possible, choose a brand that uses high-quality ingredients, like fresh basil, olive oil, and pine nuts. You can also make your own at home for the freshest taste—just blend fresh basil, garlic, pine nuts, cheese, and olive oil until smooth.
What’s the best way to store leftovers of the Creamy Pesto Chicken Pasta Bake?
To store leftovers, place them in an airtight container in the fridge for up to 3 days. It’s essential to let the dish cool completely before sealing it to prevent condensation, which can make it soggy. I recommend covering any uneaten portions tightly with foil or plastic wrap to keep them fresh!
Can I freeze the Creamy Pesto Chicken Pasta Bake?
Yes, you can! To freeze, allow the dish to cool completely after baking. Then, transfer portions into airtight containers or freezer bags. Make sure to label them with the date. It can be safely frozen for up to 2 months. When you're ready to enjoy it, thaw in the fridge overnight and reheat in the oven at 350°F (175°C) until warmed through—don’t forget to add a splash of cream or sprinkle of cheese for extra creaminess!
What should I do if my pasta becomes too mushy while baking?
If your pasta seems mushy, it may have been overcooked initially. To prevent mushy pasta in the future, always cook it al dente according to package directions, as it will continue to soften while baking. If you find yourself with mushy pasta, consider mixing it into a new sauce or bake dish right away to absorb flavors and add texture back into the dish.
Is this Creamy Pesto Chicken Pasta Bake safe for people with nut allergies?
Good question! Traditional basil pesto is made with pine nuts, which can trigger nut allergies. I suggest looking for nut-free pesto brands, or you can make your own nut-free version at home by blending fresh basil, garlic, olive oil, and Parmesan cheese, leaving out the nuts. Always check the labels to ensure it fits your dietary needs!
Can I use alternative cheeses for this recipe?
Very much so! While mozzarella and Parmesan are classic choices, feel free to experiment with other cheeses. Creamy ricotta can add richness, while a sharp cheddar can give a delightful contrast. Just be cautious with cheese that might not melt well; enjoy playing with textures and flavors!
