How To Make Dump-and-Bake Chicken Parmesan Casserole

Getting this Dump-and-Bake Chicken Parmesan Casserole ready is a cinch – all you need is a baking dish, your ingredients, and about an hour. The method is straightforward: layer your chicken and pasta, pour in the flavorful sauce and broth blend, then let the oven work its magic. A quick foil-covered bake softens everything perfectly, and a final uncovered crisp transforms the top into a bubbly, golden masterpiece. Follow these steps to turn simple ingredients into a comforting, crowd-pleasing dinner with minimal hands-on time.

1. Preheat the oven to 375°F and grease a 9×13-inch baking dish: Measure out 1 teaspoon of olive oil, then use a paper towel to coat the bottom and sides evenly so nothing sticks.

2. Cut the chicken breasts into bite-sized pieces: Trim any excess fat, then slice the chicken into uniform cubes to ensure they cook through at the same pace.

3. Combine pasta, sauce, and seasonings: Add the penne pasta, marinara sauce, 1 cup of chicken broth, the remaining tablespoon of olive oil, garlic powder, onion powder, dried oregano, dried basil, salt, and pepper. Stir gently with a spatula until everything is evenly coated.

4. Bake covered for 30 minutes: Tightly cover the dish with aluminum foil to trap steam, which helps the pasta soften and the chicken cook through.

5. Add cheese and breadcrumbs: Remove the foil and sprinkle 1½ cups of shredded mozzarella, ½ cup of grated Parmesan, and ½ cup of seasoned breadcrumbs in an even layer over the bake.

6. Return to oven uncovered and bake for an additional 10–15 minutes: Watch for the cheese to melt fully and the breadcrumbs to turn golden and crisp.

7. Rest and garnish: Let the casserole rest for 5 minutes out of the oven so the juices settle. Sprinkle 2 tablespoons of chopped fresh parsley on top before serving.

Frequently Asked Questions

Here are some quick answers to common questions that’ll make your casserole baking smooth and stress-free.

• How long does it take to prepare and cook this Dump-and-Bake Chicken Parmesan Casserole?

It takes about 10 minutes to chop the chicken, measure ingredients, and grease the baking dish. Then bake covered for 30 minutes, uncover and bake 10–15 more minutes, and let rest for 5 minutes. Total time is roughly 55–60 minutes.

• Can I substitute a different pasta shape for the penne?

Yes, you can use rigatoni or ziti instead of penne. Just be sure to stir them evenly with the sauce and broth so they cook through during the 30-minute covered bake.

• How do I ensure the chicken pieces are fully cooked?

Cut the chicken into bite-sized pieces so they cook evenly. Bake at 375°F for at least 30 minutes under foil, then an additional 10–15 minutes uncovered. You can also use an instant-read thermometer; the chicken is done at 165°F.

• Is it possible to prepare this casserole ahead of time?

• Can I add extra flavor or spice to this recipe?

Definitely. You can sprinkle in red pepper flakes or a dash of hot sauce when adding the sauce and spices. Marinating the chicken in Italian seasoning, olive oil, and a little lemon juice for 30 minutes before assembling also boosts flavor.

• What can I do if I don’t have chicken broth on hand?
