• Garlic Powder & Onion Powder – Adds depth; fresh varieties can intensify the taste.
• Part-Skim Mozzarella Cheese – Melts beautifully on top; full-fat or dairy-free alternatives can be used.

Step‑by‑Step Instructions for High Protein Chicken Parmesan Casserole
Step 1: Prep Cottage Cheese Mixture
In a blender, combine 1 ½ cups of cottage cheese, 1 egg, Italian seasoning, garlic powder, and onion powder. Blend until smooth and creamy, ensuring there are no lumps. This mixture will serve as the rich base of your High Protein Chicken Parmesan Casserole, adding both flavor and texture.
Step 2: Preheat & Grease Baking Dish
Preheat your oven to 375°F (190°C). While it’s heating, take a 9×13 inch baking dish and lightly grease it with olive oil to prevent sticking. This step is essential for a beautifully baked casserole that will easily come out in perfect portions when the time comes to serve.
Step 3: Assemble Layers
Spread 1 cup of marinara sauce evenly across the bottom of the greased baking dish. Next, layer the chicken breast pieces over the sauce, ensuring they are placed evenly without overcrowding. This will create a delightful base for the casserole, followed by your smooth cottage cheese mixture.
Step 4: Add Cheese and Marinara
Pour the prepared cottage cheese mixture over the chicken layer, spreading it gently with a spatula for even coverage. Top this layer with 1 cup of part-skim mozzarella cheese and ¼ cup of grated Parmesan cheese. Lastly, pour 1 cup of marinara sauce over the cheese, allowing the flavors to meld beautifully.
Step 5: Top Casserole
In a small bowl, mix ½ cup of breadcrumbs with 1 tablespoon of olive oil until they are thoroughly coated. Sprinkle this mixture over the top of your casserole, followed by any remaining mozzarella and Parmesan cheese. This creates a crunchy, golden-brown topping that contrasts beautifully with the creamy layers below.
Step 6: Bake
Cover the casserole loosely with foil and place it in the preheated oven for baking. Bake for 25 minutes, then carefully remove the foil and bake for an additional 15-20 minutes. Look for a bubbly, golden top as your indicator that the High Protein Chicken Parmesan Casserole is nearly ready.
Step 7: Broil for Crispiness
For that irresistible finishing touch, switch your oven to broil and broil the casserole for 1-2 minutes. Keep a close eye on it to prevent burning; you want a beautifully crispy top that enhances the dish. This step adds an extra layer of texture and flavor to your already delicious casserole.
Step 8: Rest & Serve
Once out of the oven, let the casserole sit for 10-15 minutes before cutting. This resting time allows the layers to set, making it easier to serve, and intensifies the flavors of the High Protein Chicken Parmesan Casserole. Slice, plate, and enjoy this comforting meal with your family!

Make Ahead Options
These High Protein Chicken Parmesan Casserole preparations are perfect for busy weeknights and meal planning! You can prep the entire casserole up to 24 hours in advance by assembling it and covering it tightly with foil before refrigerating. For best results, add the breadcrumbs and final layer of cheese just before baking to ensure a crispy topping. If you’re pressed for time, you can also cook the chicken and prepare the cottage cheese mixture a day ahead, storing them in separate containers. When ready to bake, simply layer the ingredients, cover, and heat at 375°F (190°C) for about 40-45 minutes until warmed through. This way, you’ll have a delicious, comforting dish ready with minimal effort!

High Protein Chicken Parmesan Casserole Recipe FAQs
What kind of chicken should I use for this recipe?
I recommend using fresh or thawed chicken breast to ensure optimal tenderness in your casserole. Avoid using chicken that looks discolored or has a slimy texture, as this can be a sign it’s not fresh.
How should I store leftovers from the casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Ensure the container is sealed well to keep the casserole fresh and flavorful.
