After a long day, I need dinner to be comforting but not exhausting, and this nailed it. The chicken stays moist because it bakes right in the sauce, and the cheese gets bubbly and golden without any fussing. I’ve made this probably thirty times since starting the blog, and it’s become my spring reset go-to.

Ingredients
Scale
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
Instructions
Heat your oven to 425°F and grease a 13-inch by 9-inch baking dish with nonstick spray.
In the baking dish or a large bowl, combine uncooked pasta, marinara sauce, water, salt, pepper, and the diced raw chicken.
Cover the dish tightly with aluminum foil to keep moisture inside and bake it for 30 minutes.
Remove the foil and stir the pasta; it will still be firm with liquid remaining.
Sprinkle mozzarella cheese evenly on top, then add the breadcrumbs and Parmesan cheese.
Return uncovered to the oven and bake for another 10 to 15 minutes until the cheese melts, the top turns golden, and the chicken is fully cooked.
If desired, sprinkle fresh herbs on top before serving.
Notes
Total cooking time varies with pan type and pasta brand
Glass or ceramic pans require more time than metal
The pasta should be al dente and absorb most liquid to avoid mushiness
For extra flavor, replace some water with red wine or add Italian seasoning, garlic powder, onion powder, crushed red pepper flakes, or sundried tomatoes

Why You’ll Love This Chicken Parmesan Casserole
This one-dish dinner gives you all the flavors you crave without the usual stovetop juggling or breading mess. It’s my go-to when I’m tired and still want dinner to feel like dinnercozy but not heavy.
Minimal prep: Everything goes into one pan, raw. No precooking pasta or chicken.
Family-friendly: Tested with real weeknights in mind. Kids love the melted mozzarella and cheesy top.
Flexible: Works with what you have. Swap penne for another pasta shape or use what’s in your pantry.
Reliable results: The chicken stays moist because it bakes right in the marinara sauce, and the breadcrumbs turn golden and crisp.
What You Need to Know About the Ingredients
Using simple, accessible ingredients is key here. The uncooked penne absorbs the marinara and water as it bakes, creating a creamy, saucy base. Raw chicken breast pieces cook through perfectly in the covered baking time, staying tender and flavorful.
The mozzarella and Parmesan melt into gooey, bubbly layers, while Panko breadcrumbs add a satisfying crunch on top. Fresh herbs like basil or parsley are optional but add a bright finishing touch.
Pro Tip: If your marinara sauce is thick, you might need a splash more water. The pasta needs enough liquid to cook through without drying out.
How the Dump and Bake Method Works
You’re skipping the usual stepsno boiling pasta, no browning chicken, no layering. Instead, everything goes into the baking dish at once. The foil traps steam, which cooks the pasta and chicken together while the flavors blend.
After 30 minutes covered, you’ll stir, then add the cheese and breadcrumbs. Those final 10-15 minutes uncovered create that golden, bubbly top everyone fights over.
Note: Glass or ceramic dishes take a bit longer than metal pans, so check your pasta by tasting a piece before serving.
Simple Swaps and Tweaks
Ingredient
Easy Swap
Penne pasta
Rigatoni, ziti, or rotini
Marinara sauce
Any jarred tomato sauce you like
Mozzarella cheese
Italian cheese blend or provolone

Timing and Doneness Guide
Total cook time hovers around 40-45 minutes, but your oven and pan type matter. Here’s what to watch for:
Stage
Time
What to Check
Covered bake
30 minutes
Pasta still firm, lots of liquid visible
After stirring
Add cheese and breadcrumbs now
Uncovered bake
10-15 minutes
Cheese melted, top golden, pasta tender, chicken cooked through
Pro Tip: Taste a piece of pasta before serving. It should be al dente, not mushy. If it’s still too firm, cover and bake 5 more minutes.
Serving and Storage Tips
Serve this straight from the baking dish with a sprinkle of fresh basil or parsley. It pairs well with a simple green salad or garlic bread if you want to stretch the meal.
Leftovers keep covered in the fridge for up to 3 days. Reheat individual portions in the microwave or warm the whole dish covered in a 350°F oven for about 15 minutes. The pasta may absorb more sauce as it sits, so it’ll be a bit thicker the next daystill delicious, just more compact.
Note: This doesn’t freeze as well as some casseroles because the pasta can get mushy when thawed, but it’s so easy to make fresh that I usually just bake it again when we want it.
How I Finally Got My Dump and Bake Chicken Parmesan Casserole Right
I thought this Dump and Bake Chicken Parmesan Casserole would be simple the first time, but it took three attempts to get the sauce-to-pasta ratio perfect. The first batch was swimming in liquid, the second too dry. Now it comes out creamy, cheesy, and exactly right every time.
FAQs ( Dump and Bake Chicken Parmesan Casserole )
Can I use frozen chicken breasts for this recipe?
Yes, you can use frozen chicken breasts without thawing first. Just add an extra 15-20 minutes to the baking time and check that the internal temperature reaches 165°F. The one-pan method works perfectly with frozen meat since everything cooks together slowly.
What type of pasta works best for this dish?
Short pasta shapes like penne, rigatoni, or ziti work wonderfully because they hold the sauce well. Use uncooked pasta straight from the box – it will absorb the flavors as it bakes. Avoid delicate shapes like angel hair as they may overcook.
How do I prevent the cheese from burning on top?
Cover the dish with foil for the first 45 minutes of baking, then remove it for the last 15-20 minutes to brown the cheese. If the top browns too quickly, tent it with foil again. This ensures the pasta cooks through while achieving that golden, bubbly finish.
Can I make this meal ahead of time?
Absolutely! Assemble everything in the baking dish, cover tightly with plastic wrap, and refrigerate for up to 24 hours. Add an extra 10-15 minutes to the baking time since it’s starting cold. It’s perfect for busy weeknight dinners.
What should I serve alongside this casserole?
A simple Caesar salad or garlic bread pairs beautifully with this hearty meal. Roasted vegetables like broccoli or green beans add nice color and nutrition. Since it’s already a complete one-dish dinner, you really just need a light side and maybe some crusty bread.
