Ingredients and Substitutions

This dish utilizes simple, accessible ingredients, which you may already have in your pantry.

Substitutions can be easily made: rotisserie chicken works wonderfully in this recipe, saving you time. If you’re looking to reduce carbs, consider using cauliflower rice instead of breadcrumbs, or experiment with gluten-free breadcrumbs if needed. For a tangier kick, you could even mix in some chopped spinach or sun-dried tomatoes for added flavor and nutrition.

How to Make High Protein Chicken Parmesan Casserole

Making this casserole is straightforward, allowing you to focus more on enjoying your meal rather than laboring over it. Follow these steps:

  1. Preheat your oven: Start by preheating your oven to 375°F (190°C), which prepares your kitchen for the deliciousness to come.
  2. Mix the ingredients: In a large bowl, combine the shredded chicken, marinara sauce, ricotta cheese, dried basil, oregano, salt, and pepper. Stir until the mixture is well combined.
  3. Layer your casserole: Pour half of your chicken mixture into a greased 9×13-inch casserole dish, spreading it evenly. Layer on half of the shredded mozzarella and Parmesan cheese.
  4. Repeat: Add the remaining chicken mixture, followed by the remaining mozzarella and Parmesan cheese, ensuring everything is well-covered.
  5. Add the breadcrumbs: For that crispy topping, sprinkle the whole wheat breadcrumbs evenly over the casserole.
  6. Bake: Place the dish in the oven uncovered for 25 to 30 minutes. You’ll want to wait until the cheese bubbles and the top turns beautifully golden brown.
  7. Serve: Let it rest for a few minutes before serving to allow the layers to set.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can assemble the casserole and refrigerate it for up to 24 hours before baking. When it’s time to bake, just allow for an additional 5-10 minutes if it’s going in cold.

How do I store leftovers?

Store the casserole in an airtight container for 3-4 days in the refrigerator. Reheat portions in the microwave or the oven until heated through.

Can I freeze it?

Yes, you can freeze the casserole either baked or unbaked. It’s best to thaw it in the refrigerator overnight before cooking or reheating.

What can I use instead of whole wheat breadcrumbs?

If you don’t have whole wheat breadcrumbs, feel free to use regular breadcrumbs, crushed crackers, or panko for a crunchy topping.

  • 1 teaspoon dried oregano
  • Salt and pepper to taste
  • 1 cup whole wheat breadcrumbs

Instructions

  • In a large bowl, mix together the shredded chicken, marinara sauce, ricotta cheese, basil, oregano, salt, and pepper until well combined.
  • Spread half of the chicken mixture evenly into a greased 9×13-inch casserole dish.

Notes

Rotisserie chicken works great and saves time. For extra crunch, lightly spray the breadcrumbs with cooking spray before baking. Letting the casserole rest helps it slice cleanly and keeps the layers intact. Leftovers taste even better the next day.
