Ingredients (Serves 4–6)

2 cups fresh spinach, chopped
8 oz cream cheese, softened
1 cup shredded mozzarella cheese (plus more for topping)
½ cup sour cream
½ cup chicken broth
1 tsp garlic powder
1 tsp onion powder
Salt and pepper to taste
½ tsp red pepper flakes (optional)
½ cup breadcrumbs (for crispy topping)

How to Make Spinach Chicken Casserole

Step 1: Preheat the Oven

Preheat your oven to 350°F (180°C). Lightly grease a medium baking dish with butter or cooking spray.

Step 2: Sauté the Spinach

In a skillet over medium heat, cook the spinach with a drizzle of olive oil for 2–3 minutes until wilted. Remove from heat and set aside.

Step 3: Make the Creamy Base

In a large bowl, whisk together the softened cream cheese, sour cream, and chicken broth until smooth. Add garlic powder, onion powder, salt, pepper, and red pepper flakes if using.

Step 4: Mix in the Chicken and Spinach

Add the shredded chicken, cooked spinach, and half of the shredded mozzarella to the cream cheese mixture. Stir well until everything is evenly coated.

Step 5: Assemble the Casserole

Pour the mixture into the prepared baking dish. Spread it out evenly. Top with the remaining mozzarella cheese and sprinkle breadcrumbs over the top for a golden, crunchy finish.

Step 6: Bake to Perfection

Bake uncovered for 25–30 minutes, or until the top is golden brown, bubbly, and the cheese is fully melted.

Step 7: Cool & Serve

Let the casserole cool for 5–10 minutes before serving. This helps the cheese set and makes it easier to slice and serve.

Optional Add-Ins

Sautéed mushrooms for an earthy flavor.
Chopped bacon or ham for a smoky twist.
Sun-dried tomatoes or artichoke hearts for a Mediterranean vibe.
Add a dash of Italian seasoning or paprika for extra depth.
