- Fresh Baby Spinach – packed with iron and vitamins A and C, adding a nutritious green touch; you may swap in thawed frozen spinach if fresh isn’t available.

Step‑by‑Step Instructions for High Protein Spinach Artichoke Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This is an essential step for ensuring your casserole bakes evenly and thoroughly. While the oven heats up, gather all your ingredients and equipment, including a large mixing bowl and a 9×13 inch baking dish, to streamline the process.
Step 2: Combine the Ingredients
In your large mixing bowl, combine shredded chicken, fresh spinach, artichoke hearts, Greek yogurt, light cream cheese, mozzarella, Parmesan, minced garlic, salt, and ground black pepper. Use a spatula to mix everything together until it’s well combined, looking for a creamy and cohesive texture that incorporates all the flavors of this High Protein Spinach Artichoke Chicken Casserole.
Step 3: Transfer to Baking Dish
Once your mixture is perfectly combined, transfer it to the greased 9×13 inch baking dish. Use your spatula to spread the chicken mixture evenly across the dish, smoothing the top for a nice presentation. This layering will help ensure consistent baking, enabling the edges to bubble beautifully while keeping the center creamy.
Step 4: Add Topping Optional
If you’re craving a crunchy finish, now’s the time to sprinkle breadcrumbs evenly over the top of your casserole. This addition not only enhances the visual appeal but also creates a delightful texture that contrasts with the creamy filling underneath. It’s a lovely option for those who enjoy extra crunch in their casseroles.
Step 5: Bake to Perfection
Place the dish in your preheated oven and bake for 25-30 minutes. Keep an eye on it; you’ll know it’s ready when the top is golden brown and bubbly, with melted cheese oozing over the edges. This visual cue indicates that your High Protein Spinach Artichoke Chicken Casserole is cooking perfectly and is nearly ready to enjoy.
Step 6: Cool Before Serving
Once baked, carefully remove the dish from the oven and allow it to cool for about 5-10 minutes. This resting period helps the layers set, making it easier to serve and ensuring that every bite holds together beautifully. The slightly cooled casserole will be easier to slice and will allow those rich flavors to meld even more.
