Chicken Parmesan casserole combines cooked shredded chicken with marinara, ricotta, garlic powder, and Italian seasoning under a mozzarella-and-Parmesan topping. This is a soft, cheesy bake with six small portions, and a cup of cooked pasta can be folded into the filling if you want it.
The chicken goes in already cooked, so the oven’s job is to heat the filling and melt the top evenly. Watch both the surface and the center: browned cheese alone does not show that the middle is hot. A short rest after baking makes the portions easier to lift from the dish.

Why This Recipe Works
Ricotta gives the tomato mixture body, while shredded chicken spreads throughout the filling rather than sitting in separate cutlets. Keeping mozzarella and Parmesan on top creates a distinct melted layer. Optional cooked pasta absorbs some sauce, so the same bake can be spoonable without pasta or a little firmer with it.
Ingredients
Main ingredients
- 2 cups cooked chicken, shredded
- 1 cup marinara sauce
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 teaspoon garlic powder
- 1 teaspoon Italian seasoning
- Salt and pepper, to taste
- 1 cup cooked pasta, optional
As Needed
- cooking oil, as needed to grease the baking dish
How to Make Chicken Parmesan Casserole
1. Heat the oven and prepare the dish. Preheat to 375°F and lightly grease a baking dish that will hold the mixture in an even, shallow layer. A very deep mound takes longer to heat through and may leave the top browned before the center is ready. Use fully cooked chicken and, if included, pasta that is already cooked and drained.
2. Mix the filling thoroughly. Stir the chicken, marinara, ricotta, garlic powder, Italian seasoning, salt, and pepper together in a bowl. Break up large pockets of ricotta so the filling heats evenly and each portion has the same balance of cheese and tomato. Fold in the optional cup of pasta only after the sauce mixture is distributed.
3. Cover with the measured cheese. Spread the mixture into the dish and scatter the full cup of mozzarella and half cup of Parmesan evenly over it. There is one filling layer and one topping layer, so the entire cheese amounts belong on top. Avoid a thick pile in the middle, which can melt unevenly and hide the filling underneath.
4. Bake and let it settle. Bake for about 25–30 minutes, until the edges bubble, the cheese is melted, and the center reaches 165°F. If the top colors early, loosely cover it with foil and continue until the middle is ready. Rest for 5 minutes before dividing into six small portions. The ricotta makes a soft filling; it is not meant to slice like a firm loaf.
How to Serve
Pair the six small portions with a green salad, garlic bread, or cooked vegetables. Adding the optional pasta gives the filling more substance without changing the number of servings. Baked Parmesan chicken is another tomato-and-cheese dinner, while Parmesan green beans make a sensible vegetable side. Air-fried chicken thighs offer a quicker chicken dinner with a different texture.
Storage and Reheating
Cool portions promptly in shallow covered containers and refrigerate at 40°F or below. Use within 3 days, counting from when the cooked chicken was first prepared. Reheat a covered portion to 165°F in the center; uncover briefly at the end if you want to dry the topping. See federal cold-storage guidance for details.
Tips and Variations
- Drain the optional cooked pasta well; extra water can loosen the tomato and ricotta mixture.
- Taste a small amount of the mixed, fully cooked ingredients before adding extra salt, since cheese and jarred marinara already contribute it.
- Use a shallow layer and distribute the topping edge to edge so it warms and melts evenly.
- Bake soon after assembling, or keep the unbaked mixture refrigerated. A cold dish may need extra oven time; check the center rather than relying on the original timer.
Frequently Asked Questions
Can I use leftover roast chicken?
Yes, remove the bones and skin and measure the shredded meat. Choose chicken that has been refrigerated promptly and is still within its storage window.
Does the pasta have to be included?
No, it is optional in this recipe. The pasta-free filling is softer and is best served with a spoon.
Can cottage cheese replace ricotta?
Well-drained cottage cheese is a possible substitute, but it gives a different texture. Blend it first if you want smaller curds in the filling.
Why is the top done before the middle?
The exposed cheese heats faster than a deep or refrigerator-cold filling. Cover the top loosely with foil and keep baking until the center is ready.
Can I freeze portions?
Freeze the baked casserole in individual covered portions if needed. Thaw them in the refrigerator, then heat a portion with a cover to help protect the cheesy surface.
