Ingredients You’ll Need
This Creamy Chicken and Spinach Casserole Recipe relies on straightforward, wholesome ingredients that pack a punch in flavor and texture. Each component plays a vital role—from the smoothness of cream cheese to the fresh bite of spinach, creating a harmonious blend that’s both hearty and nourishing.
- Boneless, skinless chicken breasts (3-4, about 1 lb): The lean protein base that cooks up tender and juicy, providing substance to the casserole.
- Fresh spinach (5-6 cups): Adds vibrant color, freshness, and a touch of earthiness that brightens the rich sauce.
- Cream cheese (8 oz, full-fat): The secret to that luscious, creamy texture that ties the dish together beautifully.
- Shredded mozzarella cheese (1 cup): Brings gooey, stretchy cheesiness that melts perfectly throughout the casserole.
- Shredded cheddar cheese (1 cup): Adds sharpness and depth, balancing the mild mozzarella and cream cheese.
- Garlic powder (2 tsp): Offers a gentle pungency that infuses the dish with warm savory undertones.
- Onion powder (2 tsp): Enhances the overall flavor with subtle sweetness and complexity.
- Low-sodium chicken broth (1 cup): Keeps the casserole moist while adding savory richness without overpowering.
- Olive oil (1 tbsp): For sautéing spinach and chicken, adding a delicate fruity note and helping with browning.
- Salt and pepper to taste: Essential seasonings to elevate every ingredient and bring harmony to the dish.
How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Preheat and Prepare
Begin by setting your oven to 375°F (190°C). This step ensures your casserole will bake evenly once all ingredients are combined and ready to go. Preheating is key to getting that golden bubbly top everyone loves.
Step 2: Sauté the Spinach
In a large skillet heated over medium heat, add the olive oil and fresh spinach. Cook just until wilted, about 2 to 3 minutes, so it keeps its lovely green color and delicate flavor. This step keeps the spinach from releasing too much water later in the casserole.
Step 3: Cook the Chicken with Seasonings
Add diced chicken breasts to the skillet along with garlic powder, onion powder, salt, and pepper. Cook everything together until the chicken loses its pink color, about 5 to 7 minutes. This step builds the foundation of savory flavor that will shine throughout the casserole.
Step 4: Create the Creamy Sauce
Lower the heat to low and stir in the cream cheese and chicken broth. Mix everything gently until the cream cheese melts into a smooth, velvety sauce. This luscious base is what makes the casserole seriously creamy and irresistible.
Step 5: Add the Cheeses and Transfer
Stir in half of the shredded mozzarella and cheddar cheeses into the skillet until melted and well combined. Then, transfer the entire mixture to a greased baking dish, spreading it evenly for uniform cooking and cheesiness in every bite.
Step 6: Top and Bake
Sprinkle the remaining shredded cheeses on top and place the dish in the oven. Bake for 25 to 30 minutes, or until the casserole is bubbly and the top is a beautiful golden brown. This finishing step creates an inviting, cheesy crust that’s simply irresistible.
How to Serve Creamy Chicken and Spinach Casserole Recipe

Garnishes
Fresh herbs like chopped parsley or basil add a pop of color and fresh aroma that brighten the richness of the casserole. A light sprinkle of red pepper flakes can also bring a gentle heat if you enjoy a bit of spice.
Side Dishes
This dish pairs wonderfully with light, crisp sides to balance its creamy weight. Think simple mixed greens with a lemon vinaigrette, roasted vegetables, or even garlic bread for soaking up every last bit of sauce.
Creative Ways to Present
For a family-style meal, serve the casserole straight from the dish with a spoon, encouraging everyone to create their own perfect portions. Alternatively, scoop individual servings onto warm plates and drizzle a touch of extra virgin olive oil or balsamic glaze for an elegant twist.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover leftover casserole tightly with plastic wrap or place in an airtight container and refrigerate. It stays fresh for up to 3 days and tastes even better after the flavors meld overnight.
Freezing
You can freeze the Creamy Chicken and Spinach Casserole Recipe before baking by wrapping the prepared casserole dish or transferring the mixture to a freezer-safe container. It will keep well for up to 3 months. Just thaw in the fridge overnight before baking as usual.
Reheating
Warm leftovers in the oven at 350°F until heated through and bubbly, about 20 minutes. If reheating individual portions, the microwave works fine—just cover loosely to retain moisture and prevent drying out.
FAQs
Can I use frozen spinach instead of fresh?
Yes, you can substitute frozen spinach, but be sure to thaw and squeeze out excess moisture before cooking to avoid a watery casserole.
Is it possible to make this casserole dairy-free?
While the creamy texture is key, you can try using dairy-free cream cheese and cheese alternatives, but the taste will be different. Experiment with what works best for your dietary needs.
Can I use other cuts of chicken?
Boneless, skinless chicken breasts are preferred for even cooking, but boneless thighs can be used for a moister casserole, though the cooking time may vary slightly.
How can I make this casserole spicier?
Adding diced jalapeños with the chicken or sprinkling cayenne pepper into the sauce are great ways to give the dish an extra kick without overpowering the creamy balance.
What can I use instead of cream cheese?
For a different but still creamy texture, Greek yogurt or sour cream can be used, though they may alter the flavor and consistency slightly.
