Ingredients

This baked chicken parmesan comes together with pantry staples and a few fresh ingredients that you probably already have hanging out in your fridge. For the base — uncooked penne pasta, marinara sauce, and water — you’re creating a self-contained cooking environment where the pasta absorbs all that saucy goodness.

For the protein and toppings — raw chicken breast, mozzarella, Parmesan, and Panko breadcrumbs — you’re building layers of Italian comfort that bubble and brown into crispy, melty perfection.

Amount	Ingredient
1 (16 ounce) package	Uncooked penne pasta
3 cups	Marinara sauce (about 1 24-ounce jar) — grab your favorite brand or use homemade if you’re feeling fancy
3 cups	Water
1 teaspoon	Salt
To taste	Ground black pepper
1½ lbs	Raw chicken breast, diced into bite-sized pieces — no need to cook it first, which is the whole magic here
1-2 cups	Shredded mozzarella cheese or Italian cheese blend — use the full 2 cups if you’re team extra cheese (highly recommended)
½ cup	Grated Parmesan cheese — the good stuff, not the green can (though honestly, no judgment)
1 cup	Panko breadcrumbs — these create that irresistible golden crust
Optional	Fresh chopped basil or parsley for garnish — because we eat with our eyes first

Tools You’ll Actually Use

• 13×9-inch baking dish
• Aluminum foil
• Large mixing spoon or spatula
• Measuring cups and spoons
• Cutting board and knife (for dicing chicken)
• Nonstick cooking spray

Step-by-Step Instructions

Making this Dump-and-Bake Chicken Parmesan Casserole is honestly so simple it almost feels like cheating — but in the best possible way.

Step 1: Preheat your oven to 425°F and spray a 13×9-inch baking dish with nonstick cooking spray. This prevents any pasta from staging a stuck-on rebellion later.

Step 2: In your prepared baking dish (or in a separate large bowl if you want fewer dishes to wash later — I always do it right in the baking dish), stir together the uncooked penne pasta, marinara sauce, water, salt, pepper, and raw diced chicken breast until everything’s well combined.

Don’t worry that it looks super liquidy right now — that’s exactly what you want. The pasta needs that liquid to cook through and get tender.

Step 3: If you mixed everything in a separate bowl, transfer it to your prepared baking dish now. Cover the dish tightly with aluminum foil — and I mean tightly, because the pasta needs to trap all that steam to cook properly. If the foil’s loose, the liquid will evaporate and you’ll end up with crunchy pasta (not the good kind of crunchy).

Step 4: Bake the covered dish for 30 minutes. Your kitchen is going to start smelling absolutely amazing around minute 20, just FYI.

Step 5: After 30 minutes, carefully uncover the dish (watch out for that steam — it’s hot!) and give everything a really good stir. The pasta will still be pretty firm at this point and there will still be quite a bit of liquid hanging around. That’s totally normal and exactly what should be happening. Don’t panic.

Step 6: Spread the shredded mozzarella cheese evenly over the top of the casserole, then sprinkle with Panko breadcrumbs and grated Parmesan cheese. This is where the magic topping happens — that crispy, golden, cheesy crust situation that makes everyone think you actually tried.

Step 7: Pop the dish back in the oven, uncovered this time, and bake for 10-15 more minutes. You’re looking for melted bubbly cheese, a golden-brown top, tender pasta, and fully cooked chicken. If you want to check, the chicken should reach 165°F internally, but honestly by this point it’s been baking for 45 minutes so it’s definitely cooked through.

Step 8: Let the casserole rest for about 5 minutes before serving — this helps everything set up a bit so you’re not just scooping out soup. Garnish with fresh chopped basil or parsley if you’re feeling fancy, then dig in.

Pro Tips & Gentle Guidance

These little tricks will take your chicken parmesan casserole from “really good” to “wait, can I have the recipe?” levels of delicious.

Want to amp up the flavor even more? Stir in a splash of red wine (about ¼ cup), a teaspoon of garlic powder, a teaspoon of onion powder, a tablespoon of Italian seasoning, or a pinch of crushed red pepper flakes when you’re mixing the raw ingredients together. These additions don’t add any extra effort but they do add major flavor depth.

If you’re working with chicken breasts that are particularly thick, dice them a little smaller than bite-sized. This helps them cook through more evenly and quickly.

Use a good-quality marinara sauce that you actually enjoy eating straight from the jar. Since the sauce is such a big player in this dish, it really does make a difference. If you’re new to choosing pasta sauces, Serious Eats has an excellent jarred sauce taste test guide that I refer to constantly.

Don’t skip the Panko breadcrumbs on top — regular breadcrumbs won’t give you that same crispy, golden texture. Panko is lighter and crunchier and that’s what creates that restaurant-quality finish.

Quick Fixes for Dump-and-Bake Chicken Parmesan Casserole

Problem: The pasta is still too firm after the initial 30-minute covered bake. Solution: Make sure the foil is sealed really tightly, then bake for another 5-10 minutes covered before adding the cheese. Some ovens run cooler, and some pasta shapes are thicker, so a little extra time isn’t unusual.

Problem: There’s still a lot of liquid after the final bake. Solution: Let it rest uncovered for 10 minutes — it’ll thicken up as it cools slightly. You can also pop it back in the oven uncovered for another 5 minutes to evaporate excess moisture.

Problem: The top is browning too quickly before the pasta is done. Solution: Tent a piece of foil loosely over the top during the final uncovered bake. This protects the cheese and breadcrumbs while the pasta finishes cooking through.

Problem: The chicken seems undercooked. Solution: Next time, dice your chicken into smaller, more uniform pieces. If you’re checking the current batch, use a meat thermometer — chicken should hit 165°F. If it’s not there yet, cover and bake another 5-10 minutes.

Variations & Adaptations

This baked casserole is super flexible, so don’t be afraid to make it your own.

Gluten-free: Swap in your favorite gluten-free penne and use gluten-free Panko breadcrumbs. The cooking method stays exactly the same.

Add veggies: Stir in a cup or two of diced bell peppers, sliced mushrooms, or fresh spinach when you’re mixing the raw ingredients. They’ll cook right along with everything else.

Spicy version: Add ½ teaspoon of crushed red pepper flakes to the sauce mixture and use pepper jack cheese instead of mozzarella. Your taste buds will thank you.

Protein swap: Ground turkey or Italian sausage (removed from casings) works beautifully here instead of chicken. Just make sure any sausage is fully cooked before you add it.

Different cheese situation: Try a mix of mozzarella, provolone, and fontina for a more complex flavor. Or go full-on Italian cheese blend from the grocery store.

Serving, Storage & Reheating

This chicken parmesan casserole is best served hot and bubbly, straight from the oven with a simple side salad and some crusty garlic bread for sopping up that amazing sauce. I also love pairing it with this Texas Caviar for a lighter, fresh contrast to all the cheesy richness.

If you somehow manage not to eat this all at once (which honestly, good luck with that), store leftovers in an airtight container in the fridge for up to 4 days. The flavors actually get even better on day two after everything’s had time to hang out together.

To reheat, microwave individual portions for 1-2 minutes, or warm the whole dish covered with foil at 350°F for about 20 minutes. You can add a splash of water or extra marinara if it seems a little dry after reheating.

No-Waste Kitchen Magic

Got leftovers? Turn them into stuffed peppers by scooping the casserole into halved bell peppers and baking at 375°F for 20 minutes. You can also use it as a filling for calzones or hand pies — just wrap it in store-bought pizza dough and bake until golden.

If the casserole’s been hanging out for a day or two and the texture’s getting a little soft, crisp it back up by spreading it on a baking sheet and broiling for 2-3 minutes. That Panko topping comes right back to life.

Day-old portions also freeze beautifully in individual containers. Just thaw overnight in the fridge and reheat — instant homemade dinner on those nights when cooking feels impossible.
