Step‑by‑Step Instructions for Chicken and Spinach Casserole with Cream Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to ensure it’s hot enough for baking the casserole. While the oven heats up, grease a 9×13-inch baking dish with a little olive oil or cooking spray, creating a non-stick surface that will allow the casserole to come out easily after baking.
Step 2: Prepare the Chicken
Slice each chicken breast in half horizontally, creating thin cutlets. To ensure even cooking, gently pound the thicker ends of the chicken cutlets with a meat mallet or rolling pin. This step will help the chicken cook uniformly, making it tender and juicy when baked in the Chicken and Spinach Casserole with Cream Cheese.
Step 3: Marinade the Chicken
In a large bowl, whisk together 1 tablespoon of olive oil, minced garlic, Italian seasoning, and a pinch of salt and pepper. Add the chicken cutlets to the bowl, ensuring they are well-coated with the marinade. Cover the bowl and let the chicken marinate in the refrigerator for 15–30 minutes, allowing the flavors to meld and enhance the dish.
Step 4: Sauté the Spinach
While the chicken marinates, heat the remaining olive oil in a skillet over medium heat. Add the fresh spinach and sauté for about 2–3 minutes, or until wilted and bright green. Once cooked, remove the skillet from heat and set the sautéed spinach aside to cool slightly before incorporating it into the casserole mix.
Step 5: Mix the Cream Cheese Filling
In a medium-sized bowl, beat the softened cream cheese until smooth and creamy. Stir in the sautéed spinach and ½ cup of mozzarella cheese until fully combined. This creamy filling brings richness to the Chicken and Spinach Casserole with Cream Cheese and adds both flavor and texture.
Step 6: Sear the Chicken (Optional)
For an extra depth of flavor, heat a drizzle of oil in a hot skillet and sear the marinated chicken cutlets for 1–2 minutes per side until they are lightly browned. This step is optional, but it creates a beautiful crust on the chicken, enhancing the savory profile of the casserole.
Step 7: Assemble the Casserole
Arrange the seared chicken cutlets neatly in the prepared baking dish, creating an even layer. Spread the creamy spinach and cream cheese mixture generously over the chicken, ensuring all the cutlets are covered. Top with the remaining mozzarella cheese for a delightful melt and golden finish while baking.
Step 8: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 20–30 minutes. Keep an eye out for the chicken to reach an internal temperature of 165°F (75°C) and the cheese to become bubbly and golden brown on top. The aroma will fill your kitchen as it nears completion.
Step 9: Rest and Serve
Once your Chicken and Spinach Casserole with Cream Cheese is perfectly baked, remove it from the oven and allow it to rest for about 5 minutes. This resting time helps the flavors settle and makes it easier to serve. Slice, dish up, and savor the comforting, creamy goodness with your family!

Make Ahead Options

You can assemble the casserole up to 24 hours in advance; simply prepare it through the assembly step, cover tightly with plastic wrap, and refrigerate.

Then, bake as instructed until melted and golden for a comforting meal that saves precious time on busy weeknights. Enjoy the same deliciousness with minimal effort!

Chicken and Spinach Casserole with Cream Cheese Recipe FAQs
How do I choose fresh spinach?
Absolutely! When selecting fresh spinach, look for vibrant green leaves that are crisp and free of dark spots or yellowing. The leaves should feel firm to the touch. If you’re opting for frozen spinach, be sure to fully thaw it and drain any excess moisture to keep your casserole from getting soggy.
How should I store leftover Chicken and Spinach Casserole?
You’ve got it! Store your leftovers in an airtight container in the refrigerator for up to 3 days. When ready to enjoy, I recommend reheating them in the oven instead of the microwave to maintain that lovely creamy texture.
Can I freeze the casserole? How?

What should I do if my casserole is too watery?
Very good question! If your casserole comes out watery, it could be due to excess moisture from the spinach or other ingredients. If you’re using frozen spinach, always make sure to thaw and drain it well before mixing. If leftovers seem watery upon reheating, try letting them sit a moment before serving, which can help excess moisture settle.
