Step‑by‑Step Instructions for Chicken and Spinach Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While the oven heats up, take a 9×13-inch baking dish and generously grease it with butter or cooking spray. This will ensure that your creamy Chicken and Spinach Casserole doesn’t stick during baking, allowing for easy serving and cleanup.
Step 2: Marinate the Chicken
Next, take your boneless, skinless chicken breasts and slice each in half horizontally. In a bowl, drizzle with olive oil, adding minced garlic, Italian seasoning, salt, and pepper. Toss everything to ensure an even coating, then cover the chicken and refrigerate for 15-30 minutes. This marinating process enhances the flavors of your Chicken and Spinach Casserole.
Step 3: Sauté the Spinach
While the chicken is marinating, heat some olive oil in a skillet over medium heat. Add in the fresh spinach and sauté for about 2-3 minutes or until wilted. Stir frequently, and once the spinach is vibrant and has reduced in size, remove the skillet from the heat. Let it cool slightly while you prepare the cream cheese mixture.
Step 4: Prepare the Cream Cheese Mixture
In a mixing bowl, beat the softened cream cheese until smooth and creamy. Gently fold in the sautéed spinach along with half of the shredded mozzarella cheese. Mix until well combined and those greens are evenly distributed. This creamy mixture will coat the chicken beautifully in your Chicken and Spinach Casserole.
Step 5: Assemble the Casserole
Now, it’s time to put everything together. Place the marinated chicken in the prepared baking dish, ensuring they’re evenly spaced. Spread the creamy spinach and cream cheese mixture over the chicken, covering it generously. Top it all off with the remaining mozzarella cheese, creating a beautiful, cheesy layer that will melt magnificently.
Step 6: Bake the Casserole
Carefully place the casserole in your preheated oven and bake for 20-30 minutes. Keep an eye on it until the chicken reaches an internal temperature of 165°F (75°C) and the cheese is bubbling and golden on top. The aroma of your Chicken and Spinach Casserole filling the kitchen will be simply irresistible!
Step 7: Rest Before Serving
Once baked, remove the casserole from the oven and let it cool for about 5 minutes. This resting time allows the cheesy goodness to settle, making it easier to serve. Everyone will appreciate your patience as they anticipate this creamy Chicken and Spinach Casserole warm on their plates.

Make Ahead Options
These Chicken and Spinach Casseroles are perfect for meal prep enthusiasts! You can marinate the chicken and sauté the spinach up to 24 hours in advance; simply store the marinated chicken in an airtight container and refrigerate the sautéed spinach separately. When you’re ready to enjoy this comforting dish, just combine the cream cheese mixture and assemble everything in the baking dish. Bake as instructed until the chicken reaches an internal temperature of 165°F (75°C) and the cheese is bubbly and golden. By prepping ahead, you’ll turn a busy weeknight into a cozy family meal, ready to enjoy with minimal effort!

Chicken and Spinach Casserole Recipe FAQs

What’s the best way to store leftovers?
Very! You can store any leftover Chicken and Spinach Casserole in an airtight container in the refrigerator for up to 3 days. It’s important to let it cool completely before covering to prevent condensation, which can make the dish soggy.

What should I do if my casserole is too watery?
If you find your casserole has excess moisture, it might be due to overcooked spinach or watery cream cheese.
