Step‑by‑Step Instructions for High Protein Spinach Artichoke Chicken Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This ensures a perfectly baked casserole. While the oven heats up, gather your ingredients and prepare your 9×13 inch baking dish by lightly greasing it with cooking spray or a drizzle of olive oil.
Step 2: Mix the Filling
In a large mixing bowl, combine the shredded chicken, fresh spinach, chopped artichokes, Greek yogurt, cream cheese, shredded mozzarella, grated Parmesan, minced garlic, salt, and pepper. Stir everything together until well-blended and creamy. Ensure the mixture is evenly coated to create a harmonious filling for your High Protein Spinach Artichoke Chicken Casserole.
Step 3: Transfer to Baking Dish
Gently transfer the filling mixture into the greased baking dish, smoothing the top with a spatula. This creates an even layer, which helps with even cooking. Make sure to spread it out to the edges for optimal melting and browning of the cheesy top.
Step 4: Bake the Casserole
Place the casserole in the preheated oven and bake for 25-30 minutes. Watch for the top to turn golden brown and bubbly, which indicates it’s ready. The edges should show slight bubbling as the cheese melts into a delightful layer.
Step 5: Cool Before Serving
Once baking is complete, carefully remove the casserole from the oven. Allow it to cool for about 5-10 minutes before serving. This resting time lets the layers set beautifully, making it easier to scoop perfect portions of the High Protein Spinach Artichoke Chicken Casserole.

How to Store and Freeze High Protein Spinach Artichoke Chicken
Fridge: Store leftovers in an airtight container for up to 3-4 days. This keeps the casserole fresh, allowing you to enjoy its creamy texture for several days.
Freezer: Freeze the casserole for up to 2 months. Ensure it’s tightly wrapped in plastic wrap and aluminum foil to protect from freezer burn.
Reheating: When you’re ready to enjoy leftovers, thaw in the refrigerator overnight. Reheat in the oven at 350°F (175°C) for about 20 minutes or until heated through.
Make-Ahead: You can prepare the High Protein Spinach Artichoke Chicken Casserole a day in advance and refrigerate it before baking, making it convenient for busy weeknights.
