Dump and Bake Chicken Parmesan Casserole Comforting Easy Win

Dump and Bake Chicken Parmesan Casserole brings all the melty cheese, tangy marinara, and golden crust you want without a single skillet to dirty first. Just layer everything raw in one pan and let the oven do the work.

I started shooting this version in early spring after too many evenings standing over the stove breading cutlets, and it honestly changed my whole weeknight rhythm. The chicken steams tender under the sauce while the cheese bubbles into crispy edges no flipping, no frying, just real comfort that doesn’t weigh you down. After testing it six times in the studio kitchen, I can confirm it photographs beautifully and tastes even better straight from the pan.

Ingredients Method Notes

Ingredients

  

• 1 (16 ounce) package uncooked penne pasta
• 3 cups marinara sauce (about 1 24-ounce jar)
• 3 cups water
• 1 teaspoon salt
• Ground black pepper, to taste
• 1 ½ lbs. raw chicken breast, diced into bite-sized pieces
• 1-2 cups shredded mozzarella cheese or Italian cheese blend
• ½ cup grated Parmesan cheese
• 1 cup Panko breadcrumbs
• Optional garnish: fresh chopped herbs such as fresh basil or fresh parsley

Method

 

1. Heat your oven to 425°F and coat a 13×9-inch baking dish with nonstick spray.
2. In the baking dish or a large bowl, combine the uncooked penne, marinara sauce, water, salt, pepper, and diced raw chicken, stirring everything evenly.
3. Cover the dish tightly with aluminum foil to trap moisture and bake for 30 minutes, allowing the pasta to soak up the liquid and the chicken to cook.
4. Remove the foil and stir the pasta gently; it will still be firm and somewhat liquidy, which is expected.
5. Scatter the shredded mozzarella evenly over the top, then sprinkle with the Panko breadcrumbs and grated Parmesan cheese.
6. Return the dish to the oven uncovered and bake for another 10 to 15 minutes until the cheese melts, the topping turns golden, the pasta is tender, and the chicken is fully cooked.
7. If desired, finish by sprinkling fresh herbs like basil or parsley over the casserole before serving.

Notes

• Cooking times may vary based on your oven and the type of baking dish used—metal pans cook faster than glass or ceramic. Check the pasta’s doneness by tasting to ensure it’s just al dente and avoid mushiness. To boost flavor, consider swapping some water for red wine or adding spices such as Italian seasoning, garlic powder, onion powder, crushed red pepper flakes, or sun-dried tomatoes if you like.

What You’ll Need

You’ll find everything at your regular grocery store, and most of it probably lives in your pantry already. The uncooked penne cooks directly in the marinara sauce and water, so no separate pot. Raw chicken breast gets diced into bite-sized pieces and tucked right init’ll cook through perfectly as the casserole bakes.

Shredded mozzarella and grated Parmesan melt into that classic stretchy, golden layer, while Panko breadcrumbs give you the crispy topping that makes chicken parm feel special. A little salt and black pepper season the base, and fresh basil or parsley at the end adds a pop of color if you’re in the mood.

How to Make It

Preheat your oven to 425°F and spray a 9×13-inch baking dish with nonstick spray. In that same dish, stir together the uncooked penne, marinara sauce, water, salt, pepper, and raw diced chicken until everything’s evenly coated. Cover the dish tightly with aluminum foilthis traps the steam so the pasta can absorb the liquid and cook through.

Bake covered for 30 minutes, then uncover and give everything a good stir. The pasta will still be firm and there’ll be liquid poolingthat’s exactly right. Sprinkle the mozzarella over the top, then add the Panko breadcrumbs and Parmesan. Bake uncovered for another 10 to 15 minutes, until the cheese is bubbly, the top is golden, and the chicken is cooked through.

Let it rest for a few minutes, then garnish with fresh basil or parsley if you like. Serve straight from the panit’s cozy, it’s easy, and cleanup is a breeze.

Timing and Baking Tips

After years of testing casseroles, I’ve learned that your pan material and pasta brand can shift bake times by 5 to 10 minutes. Glass or ceramic dishes hold heat longer and cook a bit slower than metal pans, so if your pasta still feels firm after the initial 30 minutes, that’s normaljust keep going.

Pro Tip: Taste a piece of pasta before adding the cheese. It should be nearly al dente with most of the liquid absorbed. If it’s still crunchy, cover and bake another 5 minutes. Watch the final uncovered bake closely so the breadcrumbs don’t burnonce the cheese starts bubbling and the top turns golden, you’re done.

Serving and Storage

Scoop generous portions straight from the baking dish and pair with a simple green salad or garlic bread if you want to stretch the meal. The crispy cheese edges are everyone’s favorite, so make sure each serving gets a bit of that golden crust.

Leftovers keep well in an airtight container in the fridge for up to four days. Reheat individual portions in the microwave with a splash of water to keep the pasta from drying out, or warm the whole dish covered in a 350°F oven for about 20 minutes. The flavors deepen overnight, so don’t be surprised if day two tastes even better.
