For the Pasta
- Pasta (12 oz) – Opt for tube-shaped pasta like rigatoni or tortiglioni for the best texture.
For the Chicken
- Chicken (1 lb boneless, skinless breasts, cubed) – Provides substance; may be replaced with tofu or chickpeas for a vegetarian version.
For the Flavor Base
- Italian Seasoning (1 Tbsp) – Offers a fragrant herb blend; homemade mixes work great!
- Paprika (1 tsp) – Adds warmth; skip it if you prefer a milder dish.
- Kosher Salt (1 1/4 tsp, divided) – Essential for bringing out flavors; sea salt makes a good substitute.
- Black Pepper (1/2 tsp) – Enhances taste, adjust based on your heat preference.
- Extra-virgin Olive Oil (1 to 2 Tbsp) – Use for sautéing and flavor enhancement; oil from roasted tomatoes can boost taste too.

Step‑by‑Step Instructions for Pesto Chicken Pasta Bake
Step 1: Boil Pasta
Begin by bringing a large pot of salted water to a rolling boil. Add 12 ounces of tube-shaped pasta and cook until just shy of al dente, about 7-8 minutes. Reserve 1 cup of the pasta cooking water for later use, then drain the pasta. This will create a base for your creamy Pesto Chicken Pasta Bake.
Step 2: Sauté Chicken
In a large skillet over medium heat, pour in 1 to 2 tablespoons of extra-virgin olive oil. Toss in 1 pound of cubed, boneless chicken breast along with 1 tablespoon of Italian seasoning, 1 teaspoon of paprika, 1¼ teaspoons of kosher salt, and ½ teaspoon of black pepper. Sauté for about 8 minutes, or until the chicken is cooked through and golden brown, then transfer the chicken to a plate.
Step 3: Cook Aromatics
In the same skillet, add the minced shallots (¾ cup) and sauté for about 3 minutes until they soften and become translucent. Next, incorporate 4 cloves of minced garlic and a pinch of crushed red pepper flakes, cooking for an additional minute until fragrant. Stir in 1 cup of sliced roasted tomatoes and 2 to 3 handfuls of fresh baby spinach, allowing them to wilt for about 2-3 minutes.
Step 4: Combine Sauce Ingredients
Now it’s time to bring your sauce to life! Stir in ½ cup of pesto and ½ cup of heavy cream into the skillet, mixing well to combine all the flavors into a luscious sauce that will envelop your pasta perfectly. Allow the mixture to simmer for a minute, letting the flavors meld beautifully.
Step 5: Add Pasta and Water
Add the drained pasta to the skillet, along with the reserved cup of pasta cooking water. Gently combine everything, ensuring the pasta is well coated in the creamy sauce. Cook for 2-3 minutes, and if needed, add more pasta water until the sauce reaches your desired consistency.
Step 6: Broil
Preheat your oven broiler to high. In a baking dish, transfer the pasta mixture and top it with torn fresh mozzarella (3 to 4 ounces) and the remaining ½ cup of grated Parmigiano-Reggiano cheese. Broil in the oven for about 3-4 minutes or until the cheese is wonderfully melted and bubbly, keeping a close eye to avoid burning.
Step 7: Garnish and Serve
Once the cheese is perfectly melted, remove the Pesto Chicken Pasta Bake from the oven. Sprinkle freshly chopped basil on top for a burst of color and flavor. Serve hot and enjoy this delightful dish as it becomes a new family favorite!

Pesto Chicken Pasta Bake Recipe FAQs
How do I choose the right pasta for my Pesto Chicken Pasta Bake?
Absolutely! For the best results, opt for tube-shaped pasta like rigatoni or tortiglioni. These shapes hold the creamy sauce beautifully, giving each bite a satisfying texture. If you’re looking for something gluten-free, feel free to use your favorite gluten-free pasta—it may alter the cooking time slightly, but still delivers delicious results!
How should I store leftovers?
You can store any leftovers of your Pesto Chicken Pasta Bake in an airtight container in the fridge for up to 4 days. Just reheat in the microwave or oven until warmed through. For optimum taste, enjoy it fresh, but we all know how tasty leftovers can be!
Can I freeze this pasta bake?
Yes, you can! I recommend freezing the Pesto Chicken Pasta Bake unbaked for up to 3 months. Just prepare the dish, cover it tightly, and pop it in the freezer. To bake, thaw it overnight in the refrigerator and follow your baking instructions. If you prefer to freeze it after baking, let it cool completely before wrapping it up for storage. Reheat directly from frozen or thaw it first for an easy, comforting meal!
What if my sauce turns out too thick?
Totally understandable! If you find your sauce is too thick, don’t worry! Simply add a bit more of the reserved pasta cooking water, a tablespoon at a time, and stir until you reach your desired consistency. This way, you’ll achieve that creamy texture that beautifully clings to the pasta.
Can I make this recipe vegetarian or accommodate allergies?
Of course! Substitute the chicken with tofu, chickpeas, or your favorite plant-based protein to create a vegetarian version. If you have dairy allergies, you can use a non-dairy cream and cheese alternatives to adjust the dish. Just ensure to check labels if you’re concerned about specific allergens!
How do I know my chicken is cooked through?
Very important! To ensure the chicken is fully cooked, use a meat thermometer to check the internal temperature—it should reach 165°F. Avoid cutting into the chicken until you reach that temperature; it’s a great way to maintain juiciness and prevent dryness in your dish.
