Transform your leftover rotisserie chicken into a bubbling, cheesy Chicken Parmesan Casserole that tastes like you spent hours in the kitchen. This easy baked chicken parmesan casserole with pasta is weeknight comfort food at its absolute best.

We have all been there. A store-bought rotisserie chicken sitting in the fridge, half picked over, full of potential but zero inspiration. This Leftover Rotisserie Chicken Parmesan Casserole is exactly the answer you have been looking for. It pulls together everything you already love about classic chicken parmesan and turns it into a bubbling, crowd-pleasing casserole that feeds the whole family with minimal effort.
This is the kind of baked chicken parmesan casserole that disappears fast at the dinner table. Tender shreds of seasoned chicken, hearty pasta, rich marinara sauce, and two kinds of melted cheese, all finished with a golden, buttery panko crust. It is indulgent without being fussy, and the prep time is shockingly short.
Using a good quality marinara sauce and a roomy 9x13-inch casserole dish really does make a difference in how this recipe turns out. The right tools help everything bake evenly and give you that gorgeous golden crust on top.
The beauty of a chicken parmesan casserole dish recipe like this one is in how the flavors develop during baking. The pasta absorbs the marinara, the chicken stays juicy and tender tucked into the sauce, and the cheese forms that irresistible pull when you scoop a serving. Unlike traditional chicken parmesan, which requires breading and frying individual cutlets, this baked casserole version is entirely hands-off once it hits the oven.
It is also incredibly forgiving. This is a recipe built for real life, where you might have a cup more or less chicken than the recipe calls for, or you used what pasta was already in the pantry. It still comes out great.
Chef's Tip: Do not overcook the pasta before it goes into the oven. Pull it out about two minutes early while it still has a slight bite. It will finish cooking in the sauce and stay perfectly tender rather than turning mushy.
The buttery panko and Parmesan topping is the move that takes this from a basic chicken parm bake casserole to something that looks and tastes genuinely special. Panko crumbs are lighter and crispier than regular breadcrumbs, and tossing them with melted butter before sprinkling them over the cheese means they toast up into a beautifully crunchy, golden layer that holds up even after sitting on the table.
If you want to lean into the chicken finger parmesan casserole vibe even more, you can layer sliced cooked chicken tenders over the pasta mixture before adding the cheese. It gives you bigger, more defined pieces of chicken in every bite and makes for a seriously satisfying presentation.

This easy baked chicken parmesan casserole with pasta comes together in under 15 minutes of actual hands-on prep, which makes it a perfect weeknight dinner or a make-ahead meal for a busy week.

Transform your leftover rotisserie chicken into a bubbling, cheesy Chicken Parmesan Casserole that tastes like you spent hours in the kitchen. This easy baked chicken parmesan casserole with pasta is weeknight comfort food at its absolute best.
Preheat your oven to 375 degrees F (190 degrees C). Lightly grease a 9x13-inch casserole dish with olive oil and set aside.
Cook the pasta according to package directions until just al dente, about 1-2 minutes less than the package suggests. Drain well and return to the pot.
Add the shredded rotisserie chicken, marinara sauce, Italian seasoning, garlic powder, crushed red pepper flakes, 1.5 cups of the mozzarella, and 0.5 cups of the Parmesan to the pot with the pasta. Stir everything together until evenly coated.
Transfer the mixture into the prepared casserole dish and spread it into an even layer.
In a small bowl, combine the panko breadcrumbs with the melted butter and the remaining 0.25 cups of Parmesan. Stir until the crumbs are evenly moistened.
Scatter the remaining 0.5 cups of mozzarella over the top of the casserole, then sprinkle the buttery breadcrumb mixture evenly over everything.
Bake uncovered for 30 to 35 minutes, until the cheese is melted, the sauce is bubbling around the edges, and the breadcrumb topping is golden brown.
Remove from the oven and let the casserole rest for 5 minutes before serving. Scatter fresh torn basil on top and serve warm.
Serve this parmesan chicken casserole straight from the dish with a simple green salad and some crusty garlic bread on the side. It is a complete meal on its own.
Leftovers reheat beautifully. Store them covered in the fridge for up to four days, and when you reheat, cover the dish with foil so the pasta does not dry out. A quick splash of water or a spoonful of extra marinara before reheating keeps everything saucy and fresh.
If you want to prep ahead, assemble the whole casserole the night before, cover it tightly, and refrigerate it unbaked. Pop it straight into the oven when you are ready, adding a few extra minutes to account for the cold start. It is meal prep that actually feels like a treat.
