• Prepare to indulge in this delightful dish!
For the Casserole
- Boneless, Skinless Chicken Breasts – The main protein; swap in thighs for added juiciness if you prefer.

- Fresh Spinach – Brings essential nutrients and vibrant color; you can substitute frozen, ensuring it’s thawed and excess moisture is squeezed out.
- Shredded Mozzarella Cheese – Melts beautifully on top; for unique flavors, try provolone or gouda.
- Olive Oil – Used for cooking; feel free to switch with butter or avocado oil for a different taste.
- Minced Garlic – Elevates the flavor; fresh is best, but powdered garlic works in a pinch.
- Italian Seasoning – This adds depth; a mix of dried basil, oregano, and thyme can work wonders too.

With these ingredients, you’re well on your way to creating an unforgettable Chicken and Spinach Casserole with Cream Cheese!
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) while you prepare your baking dish. Grease a 9×13-inch baking dish with olive oil or cooking spray to prevent sticking. This step ensures a hot environment for the Chicken and Spinach Casserole with Cream Cheese, allowing it to cook evenly and develop a beautiful golden crust.
Step 2: Prepare the Chicken
Cut the boneless, skinless chicken breasts in half horizontally to create thinner cutlets. Gently pound the chicken to an even thickness using a meat mallet, which aids in uniform cooking. This preparation ensures that the chicken cooks through while keeping it tender and juicy, forming the hearty base of your casserole.
Step 3: Marinate the Chicken
In a mixing bowl, whisk together olive oil, minced garlic, Italian seasoning, salt, and black pepper. Add the chicken cutlets to the marinade, ensuring they are well-coated. Allow the chicken to marinate for 15-30 minutes for the flavors to meld, enhancing the overall taste of your Chicken and Spinach Casserole with Cream Cheese.
Step 4: Sauté the Spinach
In a skillet, heat a little olive oil over medium heat. Add the fresh spinach and sauté for 2-3 minutes, or until it is just wilted. Keep an eye on it, as you want the spinach to retain its vibrant green color. Once done, remove from heat and set aside so it can cool slightly before you mix it into the casserole.
Step 5: Create the Creamy Mixture
In a bowl, beat the cream cheese until smooth and creamy. Then, fold in the sautéed spinach and half of the shredded mozzarella cheese until well blended. This mixture will bring rich creaminess and flavor to your Chicken and Spinach Casserole and will serve as the delicious layer atop the chicken.
Step 6: Optionally Sear the Chicken
Remove the marinated chicken from the bowl and, if desired, sear the cutlets in the same skillet for 2-3 minutes on each side until slightly browned. This optional step adds depth of flavor and improves the texture, though it’s perfectly fine to skip it if you’re short on time.
Step 7: Assemble the Casserole
Place the marinated chicken cutlets in a single layer at the bottom of the greased baking dish. Evenly spread the creamy spinach and cream cheese mixture over the top of the chicken, allowing it to cover the meat. Finally, sprinkle the remaining mozzarella cheese on top, ensuring a gooey finish to your Chicken and Spinach Casserole with Cream Cheese.
Step 8: Bake the Casserole
Transfer the baking dish into the preheated oven and bake for 20-30 minutes. Keep an eye on it, and look for the chicken to reach an internal temperature of 165°F (75°C) while the cheese becomes bubbling and golden brown. This baking time ensures the casserole is heated through and flavors have melded perfectly.
Step 9: Let It Rest
Once you take the casserole out of the oven, let it rest for about 5 minutes. This resting period allows the juices to redistribute, making it easier to serve and improving the overall texture. Now, your Chicken and Spinach Casserole with Cream Cheese is ready to delight your family at the dinner table!
