Olive oil: Divided to both marinate the chicken and sauté the spinach, adding a smooth base flavor.
Garlic: Fresh minced cloves bring a fragrant punch that awakens the senses.
Italian seasoning: A fragrant blend that infuses the chicken with herbal depth.
Salt and black pepper: Basic seasonings that elevate all the flavors.
Fresh spinach: Adds vibrant color and a healthy, tender bite.

How to Make Creamy Chicken and Spinach Casserole with Mozzarella and Parmesan Recipe

Step 1: Prepare the Chicken

Start by preheating your oven to 400°F (200°C) and lightly greasing a 9×13-inch baking dish to prevent sticking. Then, cut the chicken breasts horizontally so you end up with four thinner cutlets—pounding the thicker pieces helps them cook evenly and stay juicy. This prep step ensures every bite is tender and consistent.

Step 2: Marinate the Chicken

In a bowl, whisk together one tablespoon of olive oil, minced garlic, Italian seasoning, salt, and black pepper. Toss the chicken in this aromatic marinade, cover it, and let it chill for 15 to 30 minutes. This simple marination infuses the chicken with a burst of herbal and garlicky flavor that makes every mouthful exciting.

Step 3: Wilt the Spinach

While the chicken marinates, heat the remaining olive oil in a skillet over medium heat. Add fresh spinach and cook it gently for 2 to 3 minutes until wilted—and oh, the vibrant green color will brighten your casserole. Set the spinach aside; it’s about to join the creamy party.

Step 4: Mix the Cream Cheese Filling

Beat the softened cream cheese until smooth, then fold in the cooked spinach along with half a cup of shredded mozzarella. If you’re using Parmesan, add that here too. This mixture is the creamy, cheesy layer that will coat the chicken and bind all the flavors together with a luscious texture.

Step 5: Optional Searing for Extra Flavor

For a little extra depth and color, you can quickly sear the marinated chicken cutlets in a hot skillet for about 1 to 2 minutes per side. This caramelizes the outside and locks in juices before baking—totally worth the extra step if you have the time.

Step 6: Assemble the Casserole

Arrange the chicken in your prepared baking dish in a single layer. Spread the creamy spinach and cheese mixture evenly over the chicken, then sprinkle the remaining mozzarella cheese on top. This layering locks in moisture while creating a bubbly, irresistible topping as it bakes.

Step 7: Bake to Perfection

Bake the casserole in your preheated oven for 20 to 30 minutes, until the chicken reaches an internal temperature of 165°F (75°C) and the cheese topping is melted and golden brown. The aroma wafting through your kitchen at this point is pure anticipation!

Step 8: Rest Before Serving

Allow the casserole to rest for about 5 minutes outside the oven. This little pause helps the flavors settle and makes it easier to serve beautiful slices without everything sliding apart.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator, where it will stay fresh for up to 3 days. The flavors actually deepen as it chills, making for delicious next-day meals.

Freezing

This dish freezes wonderfully. After cooling, wrap the casserole tightly and place it in the freezer for up to 2 months. Thaw overnight in the fridge before reheating to preserve its creamy integrity and avoid any sogginess.

Reheating

Reheat individual portions in the microwave or the entire casserole in the oven at 350°F (175°C) until warmed through. Cover with foil to prevent excessive browning and keep that wonderful, creamy texture intact.

FAQs

Can I use frozen spinach instead of fresh?

Absolutely! Just make sure to thaw and squeeze out excess moisture from the spinach before adding it to the cream cheese mixture. This prevents your casserole from becoming watery and keeps the flavors concentrated.

Can this casserole be made gluten-free?

Yes! The recipe is naturally gluten-free as is, but always double-check that your Italian seasoning and cheeses have no hidden gluten additives to be safe.

What can I substitute for cream cheese?

You can try using ricotta cheese or a mix of cream and shredded cheeses, but keep in mind cream cheese gives the casserole its signature creamy and tangy richness that’s hard to replicate perfectly.

Is it okay to skip searing the chicken?

Definitely! Searing adds extra flavor and color but is optional. Baking the chicken directly in the casserole will still produce a juicy and satisfying dish.

How can I add more veggies to this casserole?

Feel free to toss in sautéed mushrooms, bell peppers, or even sun-dried tomatoes to amp up the vegetable content and add new flavor dimensions. Just cook them beforehand to avoid excess moisture.
