- Onion powder: Complements garlic powder with a subtle sweetness and complexity.

How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Preheat and prepare
Start by preheating your oven to 375°F (190°C). This ensures your casserole will bake evenly and develop that irresistible golden top later on.
Step 2: Sauté the spinach
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Toss in the fresh spinach and cook for 2 to 3 minutes, just until it wilts down into a vibrant, tender bed. This quick sauté releases the spinach’s moisture and concentrates its flavor, creating a perfect base for the chicken.
Step 3: Cook the seasoned chicken
Add the diced chicken breasts to the skillet along with garlic powder, onion powder, salt, and pepper. Cook everything together for about 5 to 7 minutes, stirring occasionally until the chicken is no longer pink in the center. This step ensures the chicken is fully cooked and infused with the warm, aromatic spices.
Step 4: Create the creamy sauce
Reduce the heat to low and mix in the cream cheese and chicken broth. Stir continuously until the cream cheese melts completely and the sauce is smooth and velvety. This rich, creamy base is what makes this casserole stand out and delivers that satisfying mouthfeel with every bite.
Step 5: Add the cheese and assemble
Fold in half of the shredded mozzarella and cheddar cheeses into the sauce, allowing them to melt seamlessly into the mixture. Once combined, transfer everything into a greased baking dish, spreading it out evenly to prepare for baking.
Step 6: Bake to perfection
Sprinkle the remaining shredded cheese evenly over the top of the casserole. Place it in the preheated oven and bake for 25 to 30 minutes until bubbly and golden brown on the surface. This baking step not only melts the cheese completely but also forms a delicious crust that adds a delightful texture contrast.
How to Serve Creamy Chicken and Spinach Casserole Recipe

Garnishes
To elevate this casserole further, sprinkle some freshly chopped parsley or chives on top right before serving. Their fresh herbal notes brighten up the indulgent creaminess and add a pop of green, making the dish even more inviting.
Side Dishes
This Creamy Chicken and Spinach Casserole Recipe pairs wonderfully with light sides like a crisp garden salad or steamed vegetables to balance the richness. Garlic bread or crusty baguettes also complement the dish perfectly, providing that crunchy contrast that’s just irresistible with melty casserole.
Creative Ways to Present
For a fun twist, try serving the casserole in individual ramekins for personal portions that feel special. Alternatively, garnish with a sprinkle of toasted breadcrumbs before baking to add a crunchy topping that contrasts beautifully with the creamy interior.
Make Ahead and Storage
Storing Leftovers
Keep any leftover casserole in an airtight container in the refrigerator for up to 3 days. The flavors will actually develop further, making your next meal just as delightful and convenient.
Freezing
If you want to save the casserole for a later date, freeze it before baking. Cover the dish tightly with foil and plastic wrap, then freeze for up to 2 months. When ready to eat, thaw overnight in the fridge before baking as directed.
Reheating
Reheat leftovers covered with foil in a 350°F (175°C) oven for 15 to 20 minutes until heated through. If in a hurry, microwave portions on medium power, stirring halfway to ensure even warmth while maintaining that creamy texture.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just be sure to thaw and squeeze out excess moisture from frozen spinach before sautéing to prevent the casserole from becoming watery.
Is it possible to make this casserole dairy-free?
Yes, by substituting cream cheese and cheeses for your favorite dairy-free alternatives, you can still enjoy the creamy texture and rich taste with plant-based variations.
Can I add other vegetables to this casserole?
Feel free to mix in cooked mushrooms, bell peppers, or zucchini for extra flavor and nutrition. Just sauté them along with the spinach for best results.
What type of cheese works best for melting?
Mozzarella is excellent for its stretchiness, while cheddar provides sharpness and color. Combining both gives the casserole a perfect balance of flavor and the ideal gooey texture.
How do I know when the casserole is done?
Look for a bubbly sauce around the edges and a beautifully golden brown cheese crust on top. A cooking time of 25 to 30 minutes usually ensures it’s thoroughly heated and ready to enjoy.
