Ingredients You’ll Need
Ready to make the creamiest chicken casserole? This low-carb dinner uses straightforward ingredients that create layers of rich flavor.
For the marinated chicken:
- 2 large boneless, skinless chicken breasts (halal-certified)
- 2 tablespoons olive oil, divided
- 3 cloves garlic, minced
- 1 tablespoon Italian seasoning
- ½ teaspoon salt
- ½ teaspoon black pepper
For the cream cheese mixture:
- 2 cups fresh spinach
- 8 oz cream cheese, softened
- 1 cup shredded mozzarella cheese, divided
- ½ cup Parmesan cheese (optional)
Ingredient spotlight
Cream cheese creates that signature velvety texture throughout this casserole. Softening it completely ensures smooth blending without lumps for restaurant-quality results.
Fresh spinach wilts down to just the right amount and adds iron, vitamins, and beautiful green color. Two cups might seem like a lot but they reduce significantly during cooking.
Italian seasoning delivers complex herb flavor from a single tablespoon. This blend typically includes oregano, basil, thyme, and rosemary that complement both chicken and cheese perfectly.
Mozzarella cheese melts into gooey perfection on top while also mixing into the cream cheese base. This double dose creates cheesy goodness in every single bite.
Step-by-Step Instructions
1. Preheat and prep your oven to 400°F and lightly grease a 9×13-inch baking dish with butter or cooking spray.
2. Butterfly the chicken by cutting each breast in half horizontally to create four thin cutlets. Pound the thicker ends with a meat mallet until they’re uniformly thick for even cooking.
3. Marinate the chicken by whisking together 1 tablespoon olive oil, minced garlic, Italian seasoning, salt, and black pepper in a large bowl. Add chicken cutlets, toss to coat completely, cover, and refrigerate for 15-30 minutes.
4. Wilt the spinach by heating the remaining tablespoon of olive oil in a large skillet over medium heat. Add fresh spinach and cook for 2-3 minutes, stirring frequently, until completely wilted and any liquid evaporates.
5. Make the cream cheese mixture by beating softened cream cheese in a medium bowl until smooth and fluffy. Stir in the wilted spinach, ½ cup mozzarella, and Parmesan if using until everything combines thoroughly.
6. Sear the chicken (optional but recommended) by removing cutlets from marinade, letting excess drip off, and searing in a hot skillet for 1-2 minutes per side. This adds flavor and creates beautiful golden color.
7. Assemble the casserole by arranging chicken cutlets in a single layer in your prepared baking dish. Spread the spinach and cream cheese mixture evenly over each piece, then sprinkle the remaining ½ cup mozzarella on top.
8. Bake uncovered for 20-30 minutes until the chicken reaches an internal temperature of 165°F and the cheese melts into a golden, bubbly topping.
9. Rest before serving for 5 minutes so the cream cheese mixture sets slightly. This prevents the sauce from running all over the plate when you slice into it.
Essential Equipment
9×13-Inch Baking Dish
A standard glass or ceramic baking dish distributes heat evenly for perfectly cooked chicken. The larger size gives each cutlet space to brown properly without steaming.
Meat Mallet or Rolling Pin
Pounding chicken to even thickness ensures every piece cooks at the same rate. A flat meat mallet works best, but a rolling pin gets the job done too.
Large Skillet
Wilting spinach in a 10-inch skillet lets you control the heat and monitor the process. The large surface area allows moisture to evaporate quickly for better texture.
Electric Hand Mixer (PREMIUM)
Beating cream cheese until smooth and fluffy creates the lightest, most luscious texture. An electric mixer makes quick work of softening cream cheese without lumps or exhausting your arm.

Pro Tips & Tricks
Soften cream cheese completely at room temperature for at least 30 minutes so it blends smoothly without lumps.
Drain spinach thoroughly after wilting to remove excess moisture that could make the sauce watery.
Use a meat thermometer to check for 165°F internal temperature so chicken stays juicy without overcooking.
Don’t skip butterflying because thin cutlets cook faster and more evenly than thick breasts.
