Can I make High Protein Chicken Parmesan Casserole ahead of time?

Yes! Assemble it (stop before baking), cover, and refrigerate for up to 24 hours . When ready, bake as directed—just add 5–10 minutes if it’s going in cold.

How do I store leftovers?

Store in an airtight container in the fridge for 3–4 days . Reheat in the microwave or oven until warmed through.

You can. Freeze baked or unbaked (tightly wrapped). For best texture, thaw overnight in the fridge and bake/reheat until hot and bubbly.

What can I use instead of whole wheat breadcrumbs?

Regular breadcrumbs work, panko works, crushed crackers work. The goal is that golden, crunchy top that makes everyone “accidentally” take the biggest serving.

How can I make it even higher protein?

Easy wins: Add more shredded chicken (another 1/2–1 cup). Use part-skim ricotta or a higher-protein ricotta brand if you have one. Stir in a little extra Parmesan (because… obviously).

Instructions

Preheat your oven to 375°F (190°C).
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.
Sprinkle half of the mozzarella cheese and half of the Parmesan cheese over the chicken layer.
Add the remaining chicken mixture on top, then finish with the remaining mozzarella and Parmesan cheese.
Sprinkle the whole wheat breadcrumbs evenly over the top for a crispy finish.
Bake uncovered for 25–30 minutes, until the cheese is bubbly and the top is golden brown.
Let rest for a few minutes before serving.

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.
