How to Make Dump-and-Bake Chicken Parmesan Casserole
Ingredients:
- 1 (16 oz) package uncooked penne pasta
- 3 cups marinara sauce (about 1 jar, 24 oz)
- 3 cups water
- 1 tsp salt
- Ground black pepper, to taste
- 1 ½ lbs raw chicken breast, cut into bite-sized pieces
- 1-2 cups shredded mozzarella cheese (or Italian cheese blend)
- ½ cup grated Parmesan cheese
- 1 cup Panko breadcrumbs
- Optional: Fresh chopped herbs like basil or parsley for garnish
Directions:
- Preheat your oven to 425°F and lightly coat a 13×9-inch baking dish with nonstick spray.
- In the prepared dish (or in a large separate bowl), combine the uncooked penne, marinara sauce, water, salt, pepper, and raw chicken.
- Transfer the mixture into the prepared baking dish and cover tightly with aluminum foil to trap moisture. Bake for 30 minutes, ensuring the pasta absorbs the liquid during this time.
- After 30 minutes, remove the foil and stir the mixture. At this point, the pasta will be slightly firm, and there may still be some liquid – that’s perfectly fine!
- Top with shredded mozzarella, sprinkle with breadcrumbs and Parmesan cheese.
- Continue baking uncovered for 10-15 minutes, or until the cheese is melted, the top is golden brown, the pasta is tender, and the chicken is fully cooked.
- Garnish with fresh herbs like basil or parsley if desired, then serve and enjoy!
How to Serve Dump-and-Bake Chicken Parmesan Casserole

How to Store Dump-and-Bake Chicken Parmesan Casserole

Tips to Make Dump-and-Bake Chicken Parmesan Casserole
- If you like your casserole with more sauce, feel free to add an extra cup of marinara sauce.
- You can use pre-cooked rotisserie chicken to save time. Just mix it with the other ingredients without the baking step.

Variation
For a vegetarian version, substitute the chicken with your favorite vegetables, such as zucchini, bell peppers, or mushrooms. Cook them briefly before mixing with the other ingredients.
