Step‑by‑Step Instructions for High Protein Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures your High Protein Chicken Parmesan Casserole bakes evenly and thoroughly. While your oven heats, gather your ingredients and get ready to whip this savory dish together—it’s the perfect opportunity to set the mood for a cozy family night!
Step 2: Mix the Ingredients
In a large mixing bowl, combine the cooked shredded chicken, marinara sauce, ricotta cheese, dried basil, oregano, salt, and pepper. Use a spoon or spatula to mix everything until it’s well blended. The sauce should coat the chicken thoroughly, creating a rich and flavorful base for your casserole. This mixture is the heart of your dish, so make sure it’s evenly combined.
Step 3: First Layer in the Casserole Dish
Take a 9×13 inch casserole dish and spread half of the chicken mixture evenly on the bottom. This forms the foundation of your High Protein Chicken Parmesan Casserole. Next, sprinkle half of the shredded mozzarella and grated Parmesan cheese over the layer. You’ll start to see the flavorful layers form, hinting at the delicious meal about to come.
Step 4: Repeat the Layering Process
Now, take the remaining chicken mixture and layer it on top of the first. Evenly distribute the remaining shredded mozzarella and Parmesan cheese over this layer. This step builds on the comforting appeal of your casserole. Make sure to cover every inch so the cheese melts beautifully and creates that gooey, satisfying topping we all love!
Step 5: Add the Crunchy Topping
Sprinkle whole wheat breadcrumbs generously over the top of your layered casserole. This will create a crunchy topping that beautifully contrasts with the creamy interior. The breadcrumbs should cover the cheese well while allowing some of that gooey goodness to peek through, inviting everyone to dig in once it’s baked.
Step 6: Bake to Perfection
Now, place your casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the cheese is bubbling and the top is golden brown. Keep an eye on it towards the end of baking; that melt-in-your-mouth cheese and crunchy top are worth the wait and will fill your home with wonderful aromas!
Step 7: Cool and Serve
Once baked to perfection, carefully remove the casserole from the oven and let it cool for a few minutes. This resting time allows the flavors to meld and makes serving easier. As you prepare to dish it out, drizzle extra marinara sauce on top if desired, and enjoy this delightful High Protein Chicken Parmesan Casserole with your family!
