How to Make Spinach and Artichoke Chicken Casserole

Step 1: Prepare the Oven

Preheat the oven to 375°F (190°C). Grease a suitable baking dish and set it aside.

Step 2: Combine the Chicken and Vegetables

In a large bowl, combine the diced cooked chicken, chopped artichoke hearts, and thawed, drained spinach.

Make sure the spinach is squeezed or drained thoroughly. Removing excess water is important for keeping the casserole creamy rather than watery.

Step 3: Make the Creamy Sauce

In a separate bowl, combine the mayonnaise, sour cream, grated Parmesan, 1 cup of mozzarella, minced garlic, oregano, onion powder, salt, and pepper.

Stir until the ingredients are evenly combined and the mixture is creamy.

Step 4: Combine Everything

Add the creamy mixture to the bowl with the chicken, spinach, and artichokes.

Stir gently until everything is thoroughly coated in the sauce. Take your time here so the creamy mixture is distributed evenly throughout the chicken and vegetables.

Step 5: Assemble the Casserole

Transfer the mixture to the prepared baking dish and spread it into an even layer.

Sprinkle the remaining 1 cup of mozzarella over the top. If you’re using breadcrumbs, sprinkle them evenly over the cheese for an extra-crispy topping.

Step 6: Bake

Bake the casserole for 35–40 minutes, or until it is hot and bubbling and the top is golden brown.

If the breadcrumbs or cheese begin browning too quickly, keep an eye on the casserole toward the end of baking.

Step 7: Rest and Serve

Remove the casserole from the oven and let it rest for a few minutes before serving.

This short resting time allows the creamy filling to settle slightly and makes it easier to scoop and serve.

Tips for Success

• Drain the spinach thoroughly: Frozen spinach can hold a surprising amount of water. Squeeze out as much excess moisture as possible.
• Drain the artichokes well: Excess liquid from the artichokes can also loosen the casserole.
• Use already-cooked chicken: Rotisserie chicken is a convenient shortcut, or use leftover roasted or baked chicken.
• Dice the chicken evenly: Bite-sized pieces distribute more evenly throughout the casserole.
• Don’t skip the resting time: Letting the casserole sit for a few minutes after baking helps the filling settle.
• Add breadcrumbs for texture: The creamy filling and crispy topping make a delicious combination.
• Season to taste: Parmesan and mozzarella add savory flavor, so taste the creamy mixture before adding additional salt.
