Ingredients
- ¾ pound rigatoni pasta: The sturdy pasta holds up well in baking and captures the sauce beautifully.
- 32 oz. marinara sauce (or up to 48 oz. for saucier pasta): Provides the rich, tangy tomato base. Use your preferred brand or homemade.
- 3 cups shredded mozzarella cheese, divided: Offers creamy, melty texture throughout the casserole.
- 1/3 cup grated Parmesan cheese, divided: Adds sharpness and depth. Sub with Pecorino Romano if desired.
- 2 small boneless skinless chicken breasts: Lean protein that forms the base when breaded and fried.
- ¾ cup flour: Initial coating for chicken, aiding in the breadcrumb adherence.
- 2 teaspoons seasoned salt: Enhances flavor in the chicken breading.
- 1/4 teaspoon pepper: Adds mild heat to the chicken’s coating.
- 2 eggs: Acts as a binder for the breading to adhere to the chicken.
- 1 ½ cups Italian breadcrumbs: Provides a crispy, flavorful crust.
- ¾ cup vegetable oil: Necessary for frying the chicken to golden perfection.
- 2 Tablespoons butter: Adds richness and helps the oil maintain an even frying temperature.
- Fresh Parsley, to garnish: Offers a fresh, herby note to the final dish.
How to Make It
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the rigatoni and cook until just shy of al dente, as it will finish cooking in the oven. Drain and set aside, reserving some pasta water.
Step 2: Bread and Fry the Chicken
While the pasta is cooking, prepare the chicken. Slice the chicken breasts in half lengthwise. Dredge them in flour seasoned with salt and pepper. Dip in beaten eggs, then coat with breadcrumbs. Heat the vegetable oil and butter in a skillet over medium-high heat. Fry chicken until golden and cooked through, about 4 minutes per side. Drain on paper towels.
Step 3: Assemble the Casserole
Preheat the oven to 375°F (190°C). In a large casserole dish, spread a thin layer of marinara sauce. Layer half of the cooked pasta, followed by half of the chicken pieces. Scatter half of the mozzarella and Parmesan cheeses. Repeat with remaining pasta, chicken, sauce, and finish with cheese.
Step 4: Bake and Finish
Cover the casserole with foil and bake for 20 minutes. Remove the foil and bake uncovered for another 10 minutes, or until the cheese is bubbling and lightly browned. Let rest for 5 minutes before garnishing with parsley and serving.
Tips for the Best Chicken Parmesan Casserole
- Undercook the pasta slightly — it will finish cooking in the oven so pull it out just before al dente to prevent mushiness
- Reserve some pasta water — a splash stirred into the sauce keeps everything moist during baking
- Use lots of sauce — don’t be shy! Up to 48oz of marinara keeps the casserole from drying out
- Cover then uncover — baking covered first steams everything through, then uncovering gives you that gorgeous bubbly browned cheese on top
- Let it rest 5 minutes — this helps everything set up so it slices cleanly!
- Fresh parmesan is best — pre-grated parmesan doesn’t melt as beautifully as freshly grated
What to Serve with Chicken Parmesan Casserole
- Garlic bread or crusty Italian bread — essential for mopping up sauce!
- Caesar salad
- Simple green salad with Italian dressing
- Roasted broccoli or zucchini
- Extra marinara on the side for dipping
How to Store Chicken Parmesan Casserole
Refrigerator: Cover tightly and store for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes or cover with foil and reheat in a 350°F oven for 20 minutes.
Freezer: Assemble the casserole but don’t bake it. Cover tightly with foil and freeze for up to 3 months. Bake from frozen at 375°F for 60-70 minutes covered, then 10 minutes uncovered.
Make ahead: Assemble up to 24 hours in advance, refrigerate, and bake when ready — add 10 extra minutes to the bake time!
Frequently Asked Questions
Can I make this ahead of time? Yes! Assemble the casserole a day in advance, cover tightly and refrigerate. Bake directly from the fridge adding an extra 10 minutes to the baking time.
What pasta can I substitute for rigatoni? Penne or ziti are the best substitutes — both hold sauce well and maintain texture during baking. Avoid thin pastas like spaghetti or angel hair!
Can I make this gluten free? Absolutely! Use gluten free pasta, gluten free breadcrumbs, and gluten free flour. The result is just as delicious!
Can I use jarred Alfredo sauce instead of marinara? Yes! Swap marinara for your favorite Alfredo sauce for a creamy white chicken parmesan casserole variation!
Why is my casserole dry? Use the full 48oz of marinara and don’t skip reserving pasta water. The pasta absorbs a lot of liquid during baking so more sauce is always better!
Can I double this recipe? Yes — use two 9×13 casserole dishes and bake simultaneously. Perfect for feeding a large group or freezing one for later!
