The genius of turning your chicken into a baked chicken parmesan casserole with pasta is that every component gets to shine together rather than competing.
This is genuinely a dish the whole table will get excited about.
Using a good quality marinara sauce makes a noticeable difference in this recipe, and a sturdy 9x13-inch baking dish ensures even heat distribution for that perfectly bubbly top. These are the tools and pantry staples that make a real difference when you are building a dish like this:
A few small details will take your chicken tender parmesan casserole from good to genuinely great.
Do not overcook the pasta before baking. Pull it out 1 to 2 minutes early. It will finish cooking in the oven and absorb the sauce, and overcooked pasta going into a casserole dish turns mushy fast.
Layer your cheese. Rather than dumping all the mozzarella on top, divide it between the two layers of pasta. This creates those dreamy pockets of melted cheese all the way through, not just on the surface.
Let it rest before serving. Five minutes out of the oven lets everything settle and makes it much easier to scoop clean portions without the whole thing falling apart.
Chef's Tip: For an extra-crispy breadcrumb topping, switch your oven to broil for the last 2 to 3 minutes of baking. Keep a close eye on it since the crumbs can go from golden to burnt quickly, but the texture payoff is absolutely worth it.

Transform your leftover rotisserie chicken into a cheesy, saucy Chicken Parmesan Casserole that the whole family will beg for. This easy baked chicken parmesan casserole with pasta comes together in under an hour with minimal effort.
Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch baking dish with olive oil or nonstick spray and set aside.
Cook the penne pasta in a large pot of salted boiling water until just al dente, about 1-2 minutes less than the package directions. Drain and set aside. It will finish cooking in the oven.
In a small skillet over medium heat, warm the olive oil and saute the minced garlic for about 60 seconds until fragrant. Remove from heat.
In a large mixing bowl, combine the shredded rotisserie chicken, cooked pasta, marinara sauce, sauteed garlic, Italian seasoning, red pepper flakes (if using), salt, and pepper. Stir until everything is evenly coated.
Transfer half of the pasta and chicken mixture into the prepared baking dish and spread it into an even layer.
Sprinkle 1 cup of the shredded mozzarella and half of the parmesan over the first layer.
Add the remaining pasta mixture on top, spreading it evenly. Top with the remaining 1 cup of mozzarella and the rest of the parmesan cheese.
In a small bowl, stir together the Italian breadcrumbs and melted butter until the crumbs are evenly coated. Sprinkle the buttered breadcrumbs over the top of the casserole.
Cover the baking dish tightly with aluminum foil and bake for 20 minutes.
Remove the foil and bake for an additional 12 to 15 minutes, until the top is golden and bubbly and the cheese is melted through.
Remove from the oven and let the casserole rest for 5 minutes. Garnish with fresh torn basil and serve warm.
If you somehow end up with leftovers from this parmesan chicken casserole, consider yourself lucky. They reheat beautifully.
Store any remaining casserole in an airtight container in the refrigerator for up to 4 days. To reheat, microwave individual portions with a small splash of water added to keep the pasta from drying out. For a crispier top, rewarm covered in a 350 degree F oven for about 15 minutes, then uncover for the last few minutes.
This casserole does not freeze especially well because the pasta texture changes after freezing and thawing, so plan to enjoy it fresh within the week. Given how good it is, that should not be a problem at all.
