Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Prepare the Baking Dish
Preheat your oven to 400°F (200°C) and grease a 9×13-inch baking dish with a little olive oil or butter. This will ensure that your Creamy Pesto Chicken Pasta Bake releases easily after baking. Make sure your dish is ready while you prepare the rest of the ingredients.
Step 2: Cook Pasta
In a large pot, bring salted water to a boil and add your chosen pasta, cooking it for 2 minutes less than the package instructions suggest. This step is crucial because the pasta will continue cooking in the oven. Once al dente, drain the pasta well and set it aside, giving it a gentle toss to prevent sticking.
Step 3: Sauté Chicken
Heat a tablespoon of olive oil in a large skillet over medium heat. Season the boneless skinless chicken breasts with salt and pepper, and sauté for about 5-6 minutes, or until they reach a nice golden brown and are cooked through. Once cooked, remove the chicken from the skillet and allow it to rest before slicing it into bite-sized pieces.
Step 4: Make Creamy Pesto Sauce
In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Add minced garlic, sautéing for about 30 seconds until fragrant. Then, slowly pour in heavy cream and whole milk, letting it simmer for 2-3 minutes until slightly thickened, before stirring in the basil pesto and grated Parmesan cheese until smooth and rich.
Step 5: Combine Pasta, Chicken, and Sauce
In a large mixing bowl, combine the cooked pasta and sliced chicken with the creamy pesto sauce. If you’re adding baby spinach, fold it gently into the mixture, allowing the residual heat to wilt it just enough. Ensure every piece of pasta is well coated in this luscious sauce.
Step 6: Assemble and Top
Transfer the creamy pasta mixture into your greased baking dish, spreading it evenly. Top it generously with shredded mozzarella and an extra sprinkle of grated Parmesan for that perfect bubbly finish. The cheese will create a delightful layer that’s hard to resist!
Step 7: Bake
Place the assembled dish in your preheated oven and bake uncovered for 20-25 minutes. Look for the cheese to become golden and bubbly, indicating that your Creamy Pesto Chicken Pasta Bake is ready to be taken out. The aroma will fill your kitchen with warmth!
Step 8: Rest and Serve
Once baked, remove the dish from the oven and let it rest for 5 minutes before serving. This resting period allows the flavors to meld and makes serving easier. Now, you can scoop out portions of this comforting dish and enjoy the delicious results of your hard work!

Make Ahead Options
These Creamy Pesto Chicken Pasta Bake is perfect for meal prep enthusiasts! You can assemble the entire dish and keep it in the refrigerator for up to 24 hours before baking, which is ideal for busy weeknights. Simply prepare the pasta and sauté the chicken as directed, then mix them with the creamy pesto sauce and layer it in your baking dish. When you’re ready to enjoy, bake it straight from the fridge for 20-25 minutes until the cheese is golden and bubbly. If you plan to freeze it, tightly cover the assembled bake and it will last for up to 3 months. Just thaw overnight in the refrigerator before reheating, ensuring every bite remains just as delicious!
