For the Pasta
- Pasta (penne, rigatoni, fusilli, or ziti) – Choose a shape that holds the sauce well; opt for gluten-free pasta if desired.

Step‑by‑Step Instructions for Creamy Pesto Chicken Pasta Bake
Step 1: Prepare Baking Dish
Preheat your oven to 400°F (200°C). While it warms, take a 9×13-inch baking dish and grease it lightly with cooking spray or a bit of olive oil, ensuring the bottom and sides are well-coated; this prevents the pasta bake from sticking later.
Step 2: Cook Pasta
In a large pot, bring salted water to a rolling boil. Add your choice of pasta, cooking it for about 2 minutes less than al dente according to the package instructions, typically around 7-8 minutes. Drain the pasta and set it aside, letting it cool slightly while keeping it warm.
Step 3: Sauté Chicken
Heat a tablespoon of olive oil in a large skillet over medium-high heat. Season the boneless, skinless chicken breasts with salt and pepper, then add them to the skillet. Cook for about 5-6 minutes on each side, or until they turn golden brown and reach an internal temperature of 165°F (75°C). Remove the chicken from the skillet and let it rest for a moment.
Step 4: Make Sauce
In the same skillet, reduce the heat to medium and add a tablespoon of butter. Once melted, stir in the minced garlic, cooking for about 1 minute until fragrant. Gradually pour in the heavy cream and whole milk, allowing it to simmer gently for about 3-4 minutes, thickening slightly, before mixing in the basil pesto and grated Parmesan cheese until smooth.
Step 5: Combine Ingredients
Now, return the cooked pasta and sliced chicken to the skillet, adding your optional baby spinach if using. Toss everything together in the creamy pesto sauce until the pasta and chicken are evenly coated, making sure that every bite will be rich with flavor from the Creamy Pesto Chicken Pasta Bake.
Step 6: Assemble Bake
Transfer the pasta mixture into your greased baking dish, spreading it out evenly. Sprinkle the shredded mozzarella and additional Parmesan cheese generously over the top; this will melt beautifully into a golden, bubbly crust during baking.
Step 7: Bake
Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. Keep an eye on it; you’ll know it’s done when the cheese is melted, bubbly, and slightly browned, creating an inviting and comforting look.
Step 8: Rest and Serve
Once out of the oven, let the Creamy Pesto Chicken Pasta Bake rest for about 5 minutes. This allows the flavors to meld and the dish to set slightly. Serve warm, and enjoy this delightful meal with family and friends!

Make Ahead Options
These Creamy Pesto Chicken Pasta Bake preparations are perfect for busy weeknights! You can cook the pasta and sauté the chicken up to 24 hours in advance; simply refrigerate them in separate airtight containers. Additionally, prepare the creamy pesto sauce and combine it with the pasta and chicken, then assemble the bake in the dish but don’t add the mozzarella topping yet. Cover tightly and store in the refrigerator until you’re ready to bake. When it’s time to serve, preheat your oven and sprinkle the mozzarella on top, then bake it directly from the refrigerator for 25-30 minutes until bubbly and golden. This strategy not only saves time but ensures that your meal is just as delicious and comforting when serving!

Creamy Pesto Chicken Pasta Bake Recipe FAQs
How do I choose ripe ingredients for the best flavor?
Absolutely! For the best taste, select fresh ingredients. Choose vibrant green basil pesto, fresh garlic without any dark spots, and chicken breasts that feel firm and springy; this ensures optimal flavor and texture. If you opt for spinach, make sure it’s bright green and crisp, as wilting indicates it’s past its prime.
What’s the best way to store leftovers?
Very! Store leftovers in an airtight container in the refrigerator for up to 4 days. Allow the Creamy Pesto Chicken Pasta Bake to cool completely before covering to maintain its delicious texture. Label your container with the date so you can keep track of freshness.
Can I freeze this dish, and how should I do it?
You can easily freeze your Creamy Pesto Chicken Pasta Bake! To do this, follow these steps: Wrap the assembled but unbaked dish tightly with plastic wrap or aluminum foil, ensuring no air can enter. It can stay fresh in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw overnight in the fridge and bake it, or bake it frozen at a lower temperature (starting at 325°F/165°C) for about 40-50 minutes.
What should I do if my pasta is too soft after baking?
If you ever encounter overly soft pasta, next time make sure to cook it al dente—it should have a slight bite to it before combining it with the sauce. Remember that pasta continues to cook while baking, so it’s important to pull it a couple of minutes early. If you find it’s too soft this time, mix in a bit more cheese or cream to help mask the texture.
Are there any dietary considerations for this recipe?
Absolutely! This recipe can be tailored to meet various dietary needs. For a gluten-free version, simply use gluten-free pasta. You can also leave out the chicken entirely for a vegetarian-friendly twist, and add in extra veggies like mushrooms or bell peppers if desired. Just be cautious with your pesto—some brands may contain nuts, which could be a concern for allergy sufferers.
