Before you start
Before beginning, ensure your workspace is clean and organized. Have your pasta boiled and drained, and your chicken breast cut into uniform pieces. Prepare the spinach parmesan cream sauce in advance so it is ready to pour.
Preheat your oven to 375°F (190°C) and ensure you have all your ingredients measured and within reach. Having everything prepped allows for a smooth assembly process, ensuring the chicken and pasta are coated effectively before entering the oven for the final bake.

Instructions
Preparation and Assembly
- Prepare the BasePreheat your oven to 375°F (190°C). Boil the penne in salted water until al dente, then drain well. In a large mixing bowl, combine the cooked penne with the raw bite-size chicken breast pieces. Spread this mixture evenly into the bottom of a large rectangular ceramic baking dish.Look for Pasta is tender but firm to the bite.Tip Ensure the chicken pieces are uniform in size to promote even cooking throughout the bake.
At the end of this phase, your baking dish should be filled with a uniform mixture of pasta, chicken, and sauce. The ingredients should be evenly distributed so that no portion of the dish is dry. The surface should look moist and ready to be topped with cheese. Ensure the chicken pieces are submerged as much as possible within the sauce to prevent them from drying out during the high-heat baking process.
Adding the Topping
- Assemble the BakePour the spinach parmesan cream sauce over the chicken and pasta mixture in the baking dish. Use a spoon to gently toss or spread the sauce so that all the pasta and chicken are thoroughly coated. Ensure the sauce reaches into the corners of the dish for consistent flavor.Look for The sauce coats the pasta and chicken completely.Tip Do not skip coating the edges, as this helps prevent the pasta from drying out during the baking process.
The dish is now covered with a generous, even layer of shredded mozzarella. The cheese should reach the edges of the baking dish to create a delicious crust. There should be no large gaps in the cheese layer, ensuring that the entire surface will brown evenly in the oven. This is the final step before the transformation begins in the heat of the oven, setting the stage for a beautiful golden finish.
Baking to Perfection
- Bake and ServeTop the dish generously with the shredded mozzarella cheese. Place in the preheated oven and bake until the cheese is melted, golden brown, and the sauce is bubbling, reaching an internal temperature of 165°F (74°C) in the thickest piece of chicken. Let the dish rest for 5 minutes before serving to allow the sauce to set slightly.Look for Cheese is bubbly and golden brown.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Use a meat thermometer to ensure the chicken reaches the proper temperature without overcooking the pasta.
The final result should be a beautiful, golden-brown casserole that smells savory and rich. The sauce will be bubbling around the edges of the dish, and the cheese will be melted and slightly crisp.
When you lift a serving, it should hold together well with a natural, appetizing stretch from the mozzarella. Verify the internal temperature of the chicken one last time to ensure it is safe and cooked through before you begin portioning it onto plates.
Common mistakes
A common mistake is cutting the chicken pieces too large, which can lead to uneven cooking and dry areas. Keep the pieces bite-sized to ensure they cook through within the estimated baking time.
Another error is overcooking the pasta before it goes into the oven; ensure it is al dente, as it will continue to soften while baking in the sauce. Finally, avoid using a dish that is too small, which can cause the sauce to bubble over and create a mess in your oven.
How to tell it’s done
The dish is perfectly done when the mozzarella topping is melted, golden, and slightly bubbly. Most importantly, the internal temperature of the chicken must reach 165°F (74°C). Use a digital meat thermometer inserted into the center of a chicken piece to verify this.
The pasta should be tender but not mushy, and the sauce should appear thickened and cohesive. Allowing the dish to rest for 5 minutes after removing it from the oven is crucial, as it helps the sauce stabilize before serving.
- Poultry: 165°F (74°C) in the thickest part
