Ingredient Guide

• Cooked chicken, shredded (2 cups): The protein backbone—leftover rotisserie chicken works beautifully here.
• Fresh spinach, chopped (4 cups): Adds vibrant color and subtle brightness.
• Cream cheese, softened (8 oz): Creates that luscious, creamy texture.
• Mozzarella cheese, shredded (1 cup): Melts into gooey goodness with a mild cheese flavor.
• Sour cream (1/2 cup): Brings tanginess and lightens the richness.
• Chicken broth (1/2 cup): Keeps everything moist and deepens the overall flavor.
• Garlic powder (1 tsp) & Onion powder (1 tsp): Convenient way to add savory background notes.
• Salt & pepper: To taste—season well to highlight all the other flavors.
• Breadcrumbs (1 cup, optional): For a lightly crisp topping, but easily skipped for gluten-free.
• Olive oil (1 tbsp, optional): Drizzled over breadcrumbs to enhance crunch and color.

Prep Before You Begin

Before diving into mixing, take about 15 minutes to gather and prepare your ingredients. Chop the spinach finely so it’s evenly distributed—this ensures each bite gets a little green goodness. Make sure your cream cheese is softened to room temperature; this helps it fold smoothly into the mix without leaving lumps. And don’t forget to preheat your oven to 350°F (175°C) so it’s ready to go once you assemble the casserole.

How to Make Creamy Spinach Chicken Casserole Recipe

1. Preheat your oven to 350°F (175°C). It’s best to have it ready before you start mixing, so the casserole bakes evenly without delay.
2. Combine the base ingredients. In a large mixing bowl, gently fold together the shredded chicken, chopped spinach, softened cream cheese, half of the shredded mozzarella, sour cream, and chicken broth. You’ll notice how the mixture becomes creamy and slightly glossy—this means the textures are melding beautifully.
3. Season the mixture. Sprinkle in garlic powder, onion powder, salt, and pepper. Give it a thorough stir to distribute all those aromatic flavors—you want each bite to be well seasoned.
4. Transfer the mixture. Pour the creamy chicken and spinach blend into a greased 9×13 inch baking dish. Spread it evenly with a spatula, making sure there are no thick lumps. The even layer helps everything cook at the same rate and results in a consistent texture.
5. Add optional crunch. If you’re using breadcrumbs, sprinkle them evenly over the top. Drizzle the olive oil lightly—this step encourages a golden, crispy topping that contrasts nicely with the creamy interior.

6. Top with the remaining mozzarella cheese. This will melt and form that irresistible, golden cheesy crust that you’ll love breaking into.

Storage, Freezing & Reheating

• Freeze individual portions wrapped tightly for up to 2 months; thaw overnight before reheating.
• Reheat in a 325°F (165°C) oven until warmed through to maintain the casserole’s shape and creaminess.
• Avoid microwaving directly from frozen to keep the top’s crispness and avoid rubbery cheese.
