This creamy chicken and spinach casserole gets rave reviews every time I make it, whether for a casual weeknight dinner or a cozy potluck with friends. Tender chicken cutlets are layered with spinach and a luscious cream cheese sauce, then crowned with gooey mozzarella for an irresistible comfort dish.
This was a lifesaver on a busy school night and my family instantly asked for seconds. It is now a frequent flyer in our weeknight rotation.
Ingredients
- Chicken breasts: Provide a lean and juicy base Pick fresh or organic if possible for best taste
- Olive oil: Keeps everything moist and adds flavor Choose extra virgin for better depth
- Garlic: Brings out aromatic warmth Look for firm cloves with no sprouting
- Italian seasoning: Adds brightness Use your favorite blend or make your own for extra pizazz
- Salt: Accents all the flavors A fine sea salt works well here
- Black pepper: Gives gentle spice Always use freshly cracked for max flavor
- Fresh spinach: Brings color and nutrients Baby spinach is tender and cooks down beautifully
- Cream cheese: Yields velvety creaminess Letting it soften makes mixing a breeze
- Mozzarella cheese: Delivers gooey goodness Buy it fresh and grate it for the melt factor
- Parmesan cheese: Adds a nutty bite Fresh shaved is wonderfully rich but use pre-grated if time is short
Step-by-Step Instructions
- Prep the Chicken:
- Slice each breast in half horizontally to form flat cutlets. Even out any thicker areas by gently pounding them with a rolling pin or meat mallet until all pieces are an even thickness. This helps everything cook evenly.
- Marinate the Chicken:
- Whisk together olive oil, garlic, Italian seasoning, salt and pepper in a large bowl. Add the chicken cutlets and toss to coat each piece well. Cover the bowl and let the chicken chill in the fridge for at least fifteen minutes. This builds juiciness and flavor into every bite.
- Wilt the Spinach:
- Heat another splash of olive oil in a large skillet set over medium heat. Add all the fresh spinach and cook, stirring often, until it collapses and wilts down completely. This should take just two or three minutes. Set it aside to cool.
- Mix the Creamy Layer:
- In a medium bowl, beat the softened cream cheese until entirely smooth. Stir in the wilted spinach along with half the mozzarella and the Parmesan if using. Blend well to create a lush, creamy filling.
- Assemble the Casserole:
- Drain and shake excess marinade from the chicken. For extra flavor and color, quickly sear each cutlet for one or two minutes per side in your skillet. Arrange the chicken in a single even layer in your greased baking dish.
- Layer and Top:
- Spoon the cream cheese spinach mixture all over the chicken, spreading it right to the edges. Sprinkle the rest of the shredded mozzarella cheese evenly over the top for that golden bubbly finish.
- Bake to Perfection:
- Slide the dish into your hot oven and bake for about twenty to thirty minutes until the chicken is cooked through and the cheesy top is beautifully melted and golden browned at the edges. Rest it for a few minutes before serving to help the creaminess settle in.

I love the magic that happens when cream cheese bakes with mozzarella and real spinach. My daughter always sneaks a forkful as soon as it leaves the oven which tells me this is real comfort food at its best.
Storage Tips
Leftovers will stay tasty for up to three days in the refrigerator if stored in a tightly sealed container. If making ahead for the week I let the casserole cool fully before packing individual servings for the lunchbox. For best results reheat in the oven or toaster oven so the top gets bubbly again.
Ingredient Substitutions
Chicken thighs work just as well for extra richness though they will need a slightly longer cooking time. Swap fresh spinach for thawed frozen spinach in a pinch just remember to squeeze out excess water. Cream cheese can be replaced with mascarpone for a silkier finish and any mild melting cheese like fontina can stand in for mozzarella.

Serving Suggestions
This casserole pairs well with a crisp green salad or classic roasted vegetables for balance. Sometimes I serve it over rice or buttered noodles to soak up all the cheesy sauce. My family also likes it spooned onto toasted bread for a heartier meal.
Cultural Context
Baked casseroles like this one have deep roots in family and communal cooking often showing up at gatherings where comfort and sharing matter most. Adding a layer of greens and rich cheese is a common way to turn simple chicken into a festive centerpiece. You will find similar dishes across regions especially in European and American home kitchens.
Frequently Asked Questions
- → How can I tell when the chicken is cooked through?
The chicken is fully cooked when it reaches an internal temperature of 165°F. The juices should run clear when sliced.
- → Can I use frozen spinach instead of fresh?
Yes, thaw and drain frozen spinach well before mixing. Be sure to squeeze out excess moisture to prevent a watery casserole.

You can substitute mozzarella with Monterey Jack or provolone for a different melt and flavor. Parmesan adds sharpness but can be left out if preferred.
- → Is searing the chicken necessary?
Searing is optional. It adds flavor and color, but the chicken will still cook thoroughly and remain tender if baked raw.
