Some nights you need dinner in the oven in five minutes and off the table before anyone melts down.
This is that recipe. Water, pasta, marinara, and chicken straight into one pan. Foil on top. Into the oven.
No chopping. No browning.
No second pan on the stove.
Just one casserole dish that you pull out 30–45 minutes later with tender pasta,
fully cooked chicken, and enough surface area to layer on the cheese and Panko topping that makes this taste like real chicken parm rather than just another dump and bake pasta casserole.
The thin chicken breasts are the move here.
They cook through at the same rate as the pasta, which means everything is ready at the same time without adjusting anything.
It’s the kind of detail that sounds small but makes these dump and bake dinners actually work on a Tuesday when you’re already tired.
Garlic salt, mozzarella, Parmesan, and Panko go on at the end. Five minutes uncovered and the top is golden.
One of those easy dinner recipes that earns its place in the weekly rotation not by being impressive, but by being completely reliable.

For the Easy Chicken Parmesan Casserole
- Barilla ProteinPlus Penne – More protein per serving than standard pasta, same cook time, same texture. It’s the pasta upgrade that actually makes sense in a dump and bake chicken parmesan recipe — you’re already putting in so little effort, the pasta might as well work harder. Any penne works if you can’t find ProteinPlus.
- Marinara Sauce – One full jar stirred into the water and pasta before the chicken goes in. Use a sauce you like on its own — the flavor carries through every bite of this casserole recipe.
- Water – Combined with the marinara to give the penne enough liquid to absorb and cook through in the oven. The pasta soaks up both as it bakes, which means every noodle comes out saucy rather than dry.
- Thin Boneless Skinless Chicken Breasts – Placed whole on top of the pasta and sauce mixture. Thin breasts are what make this one of the most reliable dump and bake chicken recipes — they cook through at the same pace as the pasta so nothing is overcooked or undercooked when you pull the dish out.
For the Topping
- Shredded Mozzarella – The melty layer that goes on right before the final uncovered bake. One cup is enough to cover the casserole and give you that gooey cheese pull that makes this feel like real chicken parm.
- Grated Parmesan – The sharp, salty counterpoint to the mozzarella. Mixed into the topping alongside the breadcrumbs for that classic chicken parm flavor profile.
- Panko Breadcrumbs – Scattered over the cheese for crunch. At 425°F they go golden in just 5 minutes — the quickest topping of any dump and bake chicken parmesan casserole on this list.
- Garlic Salt – Sprinkled over the topping before the final bake. It seasons the cheese and breadcrumbs together and is the small flavor detail that makes this taste like more than a simple weeknight casserole.
- Fresh Parsley – Scattered over at the end for color and a little freshness against the rich sauce and melted cheese.

Notes
Ingredients
- 1 (14.5 oz) box Barilla ProteinPlus Penne pasta (or any penne)
- 1 (24 oz) jar marinara sauce
- 2 cups water
- 1½ lbs thin boneless skinless chicken breasts
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- ½ cup Panko breadcrumbs
- Garlic salt, to taste
- Fresh parsley, to garnish
Instructions
- Preheat your oven to 425°F.
- Pour the water and dry penne pasta directly into a 9x13-inch casserole dish. Add the marinara sauce and stir to combine.
- Trim any excess fat from the chicken breasts if needed and place them directly on top of the pasta and sauce mixture — no need to cut them up.
- Cover the dish tightly with aluminum foil to trap moisture. This is what cooks the pasta and chicken together in the oven.
- Bake covered for 30–45 minutes until the pasta is tender and the chicken is cooked through. Start checking at 30 minutes — the chicken should reach 165°F internally.
- Remove from the oven. Scatter the mozzarella, Parmesan, and Panko breadcrumbs evenly over the top. Sprinkle with garlic salt.
- Return to the oven uncovered for 5 minutes until the cheese is melted and the breadcrumbs are lightly browned.
- Garnish with fresh parsley and serve straight from the dish.
- Thin chicken breasts are key: Thick breasts take longer to cook and the pasta ends up overdone by the time the chicken catches up. Buy thin-sliced breasts or butterfly your own. This is the single most important tip for getting this dump and bake chicken parmesan casserole right.
- Check at 30 minutes: Every oven runs differently. Start checking the pasta at 30 minutes — taste a noodle. It should be nearly al dente. The chicken should register 165°F on a meat thermometer.
- Protein boost: Barilla ProteinPlus pasta adds more protein per serving than standard penne. If you're tracking macros or feeding active kids, it's a straightforward upgrade that doesn't change the flavor or the method.
- Storage: Leftovers keep in an airtight container in the fridge for up to 3 days. For longer storage, freeze for up to 30 days. Reheat covered in a 350°F oven for about 10 minutes.
- Reheating tip: Cover with foil before putting back in the oven — it keeps the pasta from drying out while the cheese re-melts.
Why use thin chicken breasts instead of regular ones?
Thin chicken breasts cook through at the same rate as the pasta — around 30–45 minutes at 425°F. Thick breasts take significantly longer, which means the pasta will be overcooked and mushy by the time the chicken is safe to eat. It’s the single most important tip for making dump and bake chicken recipes work without pre-cooking anything. Buy thin-sliced breasts or butterfly your own.
How do I know when the casserole is done?
Two checks: taste a piece of pasta — it should be al dente with most of the liquid absorbed — and confirm the chicken has reached 165°F internally with a meat thermometer. Start checking at 30 minutes. If the pasta is still very firm, recover and give it another 10 minutes before testing again.
Can I use regular penne instead of ProteinPlus?
Yes — any penne with a similar package cook time works perfectly in this casserole recipe. The ProteinPlus pasta adds extra protein per serving which is useful if you’re tracking macros or feeding active kids, but it doesn’t change the method or the flavor at all. Use whatever penne you have.
Can I cut the chicken into pieces instead of leaving it whole?
Yes. Dicing the chicken into bite-sized pieces before adding it to the dish is a good call if you want more even distribution through the pasta. It also reduces the covered bake time slightly since smaller pieces cook faster. Just make sure you’re still using thin breast meat rather than thick cuts.
How long do leftovers keep and can I freeze them?
Leftovers keep in an airtight container in the fridge for up to 3 days. For longer storage, this is one of the dump and bake dinners that freezes reasonably well — up to 30 days in the freezer. Reheat covered in a 350°F oven for about 10 minutes. The foil cover is important — it keeps the pasta from drying out while the cheese warms back through.
