- 1/2 cup sour cream: Adds tangy richness and a smooth consistency.
- 1/2 cup shredded mozzarella cheese: Melts beautifully for that gooey, cheesy comfort.
- 1/4 cup grated Parmesan cheese: Delivers a savory, slightly nutty flavor that elevates the entire dish.
- 1/2 teaspoon onion powder: A subtle seasoning to enhance the flavor without overpowering the other ingredients.
- 1/2 teaspoon dried thyme: Adds gentle earthiness and a hint of herbal brightness.

How to Make Chicken and Spinach Casserole with Cream Cheese Recipe
Step 1: Prepare Your Oven and Pan
Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish to ensure your casserole doesn’t stick and can come out easily once baked.
Step 2: Sauté Garlic and Spinach
In a large skillet over medium heat, warm the olive oil. Add the minced garlic and sauté it for about 30 seconds until fragrant. Then toss in the chopped spinach and cook until it wilts down nicely, which usually takes 2 to 3 minutes. This step intensifies the spinach’s flavor and removes any excess moisture. Once ready, remove the skillet from heat.
Step 3: Combine Cheeses and Seasonings
In a spacious mixing bowl, beat together the softened cream cheese and sour cream until smooth and creamy. Add the shredded mozzarella and grated Parmesan, then sprinkle in the onion powder, dried thyme, salt, and black pepper. This cheese mixture is the heart of the casserole, so don’t rush—make it silky and well blended.
Step 4: Mix in Chicken and Spinach
Gently fold the cooked chicken and sautéed spinach into the cheese mixture. Ensure everything is evenly combined, so each bite is packed with flavor and luscious texture.
Step 5: Bake to Perfection
Transfer your mixture into the prepared baking dish, smoothing it out evenly. If you love a crispy top, sprinkle the breadcrumbs over it now. Pop it in the oven for 20 to 25 minutes until the casserole bubbles happily and turns a gorgeous golden brown on top. After removing, let it rest for 5 minutes to set before serving.
How to Serve Chicken and Spinach Casserole with Cream Cheese Recipe

Garnishes
To elevate the presentation and add a little extra zing, try garnishing with fresh chopped parsley or a sprinkle of crushed red pepper flakes. These simple touches brighten the plate and add a pop of color and flavor that’s sure to impress.
Side Dishes
This casserole pairs wonderfully with light, fresh sides. Consider a crisp green salad with a tangy vinaigrette or steamed asparagus to balance the richness. For a cozier meal, creamy mashed potatoes or roasted sweet potatoes are fantastic companions.
Creative Ways to Present
If you want to bring a fresh twist, serve the casserole in individual ramekins for a charming, personalized touch. Alternatively, scoop portions onto a bed of whole grain rice or quinoa for a complete meal that’s both hearty and elegant.
Make Ahead and Storage
Storing Leftovers
Leftovers keep beautifully in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight, making the next day’s meal just as delicious.
Freezing
You can freeze this casserole for up to 2 months. Just assemble it in a freezer-safe dish, cover tightly with foil or plastic wrap, and freeze. When ready to enjoy, thaw overnight in the fridge before baking.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until hot and bubbly. If you’re in a rush, the microwave works well too—just cover loosely and warm in 1-minute intervals, stirring occasionally for even heating.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just make sure you thaw and squeeze out as much moisture as possible from the frozen spinach before sautéing, so your casserole doesn’t become watery.
Is this recipe gluten-free?
It certainly can be. Simply omit the breadcrumbs or use gluten-free breadcrumbs for the topping to keep it safe for gluten-sensitive diets.
Can I add other vegetables to this casserole?
Yes! Feel free to toss in mushrooms, bell peppers, or zucchini to add more variety, flavor, and nutrients. Just sauté the veggies before mixing them in.
How can I make this casserole spicier?
Add a pinch of red pepper flakes or some chopped jalapeños to the cheese mixture for a little kick that wakes up the creamy flavors.
Is this dish freezer-friendly after baking?
It’s best to freeze the casserole before baking for optimal texture. Freezing after baking can affect the creaminess and texture, but if you do, reheat gently to avoid drying out.
