Step‑by‑Step Instructions for Pesto Chicken Pasta Bake
Step 1: Boil the Pasta
Bring a large pot of salted water to a rolling boil. Add your choice of tube-shaped pasta, such as rigatoni, and cook until just shy of al dente, about 8–10 minutes. Reserve 1 cup of the pasta cooking water before draining. This step ensures a perfect base for your Pesto Chicken Pasta Bake.
Step 2: Cook the Chicken
While the pasta is boiling, season boneless skinless chicken breasts with olive oil, Italian seasoning, paprika, kosher salt, and black pepper. Heat a skillet over medium heat and sauté the chicken for about 8 minutes, or until fully cooked and golden brown on both sides. Set the chicken aside to rest while you prepare the sauce.
Step 3: Sauté Aromatics
In the same skillet, add shallots and sauté for about 3 minutes until they become tender and fragrant. Then, stir in minced garlic and crushed red pepper flakes; cook for an additional minute, allowing the garlic to release its aroma. This aromatic base will enhance the flavors of your Pesto Chicken Pasta Bake.
Step 4: Add Vegetables
Next, incorporate the roasted tomatoes and fresh baby spinach into the skillet, cooking for 2–3 minutes until the spinach wilts down. Season with a pinch of kosher salt to enhance the overall flavor. The vibrant colors of the vegetables will start to create a beautiful medley in your Pesto Chicken Pasta Bake.
Step 5: Create the Sauce
Stir in the pesto and heavy cream, mixing well to combine. Gradually add the drained pasta along with the reserved cooking water, stirring until the sauce thickens and coats every piece of pasta. This creamy mixture brings an irresistible richness to your Pesto Chicken Pasta Bake.
Step 6: Combine Chicken and Cheese
Gently fold in half of the grated Parmigiano-Reggiano cheese into the pasta mixture. Return the sautéed chicken to the skillet and mix everything thoroughly until well combined. The chicken mingling with the creamy sauce makes for a hearty and satisfying Pesto Chicken Pasta Bake.
Step 7: Broil for Perfection
Preheat your broiler to high. Spoon the pasta mixture into an oven-safe baking dish, then top it with fresh mozzarella and the remaining Parmigiano-Reggiano cheese. Broil for 3–4 minutes, or until the cheese bubbles and turns golden brown, creating a delicious, gooey topping for your Pesto Chicken Pasta Bake.
Step 8: Garnish and Serve
Once everything is melted and bubbly, remove from the broiler and let it sit for a few minutes. Garnish with fresh basil leaves for a burst of color and flavor. Now your comforting Pesto Chicken Pasta Bake is ready to be served, inviting everyone to enjoy a warm, hearty meal together!

Expert Tips for Pesto Chicken Pasta Bake

- Broiler Safety: Always ensure your skillet is oven-safe before broiling. A sudden temperature change can crack the pan!
- Cheesy Delight: For an extra layer of flavor, mix in some cheese directly into the pasta before broiling. It makes the Pesto Chicken Pasta Bake even more indulgent.

Make Ahead Options
These Pesto Chicken Pasta Bake preparations are a lifesaver for busy weeknights! You can assemble the pasta bake up to 24 hours in advance.
