- Salt: Heightens the overall flavors.

How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Preheat and Prep
Begin by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish thoroughly to ensure your casserole doesn’t stick and comes out beautifully after baking.
Step 2: Season the Chicken
Sprinkle the chicken breasts evenly with salt, black pepper, paprika, and onion powder. These spices work together to create a savory, well-rounded flavor base that makes every bite irresistible.
Step 3: Sear the Chicken
Heat olive oil in a skillet over medium-high heat. Sear the chicken breasts for about 2-3 minutes on each side, just until they develop a tantalizing golden brown crust. Don’t worry if they aren’t cooked through — baking will finish the job.
Step 4: Prepare the Cream Cheese Mixture
In a bowl, combine the softened cream cheese, sour cream, minced garlic, and a pinch of salt. Mix until smooth and silky, creating that signature creamy sauce that makes this casserole so comforting and indulgent.
Step 5: Assemble the Casserole
Spread fresh spinach evenly across the bottom of the greased baking dish. This layer not only adds vibrant color but also a subtle earthy note that complements the richness of the cream cheese sauce.
Step 6: Add Chicken and Cream Cheese
Place the seared chicken breasts on top of the spinach. Then, spread the cream cheese mixture evenly over the chicken, ensuring every piece is coated in that luscious, garlicky sauce.
Step 7: Top with Mozzarella and Bake
Generously sprinkle shredded mozzarella over the entire casserole. Bake in the preheated oven for 25-30 minutes. The cheese will melt into a bubbly, golden topping while the chicken finishes cooking to juicy perfection.
Step 8: Rest and Serve
Let the casserole rest for about 5 minutes after baking. This allows the flavors to settle and makes serving easier, ensuring each portion holds its cheesy, creamy goodness.
How to Serve Creamy Chicken and Spinach Casserole Recipe

Garnishes
A sprinkle of freshly chopped parsley or chives brightens the rich casserole with a touch of color and fresh flavor. For a bit of crunch, toasted breadcrumbs scattered on top just before serving add a delightful texture contrast.
Side Dishes
This casserole pairs beautifully with light sides like a crisp garden salad or garlic-roasted asparagus to balance the richness. For a heartier meal, creamy mashed potatoes or buttery rice pilaf create a cozy, filling plate.
Creative Ways to Present
For a dinner party, serve individual portions in small ramekins for elegant plating. You can also top each piece with a dollop of pesto or sun-dried tomato tapenade to add a burst of flavor and stunning color contrast.
Make Ahead and Storage
Storing Leftovers
After cooling, cover the casserole tightly with foil or plastic wrap and refrigerate for up to 3-4 days. The flavors meld wonderfully overnight, making leftovers just as delicious the next day.
Freezing
This creamy chicken and spinach casserole freezes well. Place it in a freezer-safe container or wrap it well with foil, then freeze for up to 2 months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat in the oven at 350°F (175°C) for 15-20 minutes until warmed through and bubbly. You can also microwave individual portions, but oven reheating helps maintain that lovely melted cheese texture.
FAQs
Can I use frozen spinach instead of fresh?
Yes, frozen spinach works fine but make sure to thaw and squeeze out excess moisture to avoid a watery casserole. Fresh spinach provides a brighter color and fresher taste.
Is this recipe suitable for meal prepping?
Absolutely! This casserole keeps well refrigerated and freezes wonderfully, making it a fantastic option for prepping meals in advance.
Can I substitute the cream cheese?
You can try using ricotta or mascarpone for a different texture, but cream cheese gives the best creamy consistency and flavor for this recipe.
How do I know when the chicken is fully cooked?
Make sure the internal temperature of the chicken reaches 165°F (75°C). The baking time should be sufficient, especially after searing the breasts first.
Can I add other vegetables to this casserole?
Yes! Mushrooms, bell peppers, or sun-dried tomatoes are great additions that complement the creamy base and fresh spinach.
