Step‑by‑Step Instructions for High Protein Chicken Parmesan Casserole
Step 1: Preheat and Prepare the Baking Dish
Start by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9×13 inch baking dish and grease it lightly with olive oil or cooking spray to prevent sticking. This will ensure your High Protein Chicken Parmesan Casserole comes out with ease and maintains its lovely texture when serving.
Step 2: Make the Cottage Cheese Mixture
In a medium bowl, combine the low-fat cottage cheese, egg, Italian seasoning, garlic powder, and onion powder. Use a fork or a blender to mix until smooth and creamy, giving your casserole a rich base. This mixture will bind the ingredients together and infuse wonderful flavor throughout the High Protein Chicken Parmesan Casserole.
Step 3: Layer the Ingredients
Spread 1 cup of marinara sauce evenly over the bottom of the prepared baking dish. Carefully place the seasoned chicken breast pieces on top of the sauce, ensuring they are evenly distributed. Next, spoon the creamy cottage cheese mixture over the chicken, smoothing it gently for even coverage. Then, sprinkle 1 cup of mozzarella and ¼ cup of grated Parmesan cheese atop the layers, creating a delicious foundation for your casserole.
Step 4: Add More Marinara and Topping
Pour another cup of marinara sauce over the cheese layer, making sure all areas are covered to keep the dish moist. In a small bowl, mix the breadcrumbs with 1 tablespoon of olive oil until evenly coated. Sprinkle this breadcrumb mixture over the entire top of the casserole, adding texture and crunch. Finish by generously layering on the remaining mozzarella and Parmesan cheese, ensuring a gooey, cheesy finish.
Step 5: Bake Covered
Cover the casserole tightly with aluminum foil to retain moisture as it bakes. Place it into the preheated oven and bake for 25 minutes. This initial baking phase helps cook the chicken fully while allowing the flavors to meld beautifully in the High Protein Chicken Parmesan Casserole.
Step 6: Bake Uncovered for Browning
After 25 minutes, carefully remove the foil and bake the casserole uncovered for an additional 15-20 minutes. Keep an eye on it, and look for bubbly cheese and a golden-brown topping to signal it’s ready. If you prefer an extra crispy top, turn on the broiler for the last few minutes—a great way to achieve that perfect finish.
Step 7: Rest Before Serving
Once the casserole is beautifully browned and bubbly, remove it from the oven and allow it to rest for 10-15 minutes. This step is crucial as it lets the casserole set and makes serving easier without losing its delicious layers. Now, your High Protein Chicken Parmesan Casserole is ready to be sliced, served, and enjoyed!
