- 2 cups cooked chicken (shredded or cubed): Use leftover roast chicken or poached chicken for the best tenderness and flavor.
- 10 oz frozen spinach (thawed and drained): Frozen spinach holds moisture well and gives vibrant color and nutrition.

- 1 small onion (diced): Brings sweetness and depth when cooked down.
- 2 cloves garlic (minced): Adds an aromatic punch that wakes up the whole dish.
- 1 can (10.5 oz) cream of chicken soup: The creamy base that ties everything together flawlessly.
- 1/2 cup sour cream: Adds tangy creaminess that makes the casserole indulgently smooth.
- 1/2 cup milk: Helps achieve that perfect saucy consistency without heaviness.
- 1 teaspoon Italian seasoning: Blends herbs like basil and oregano for a classic savory note.
- 1/2 teaspoon salt: Balances flavors and enhances the dish’s natural taste.
- 1/4 teaspoon black pepper: Adds a gentle warmth and spice.
- 1/4 teaspoon crushed red pepper flakes (optional): For those who like a hint of heat in their comfort food.
- 1 1/2 cups shredded mozzarella cheese: Melts beautifully, creating that irresistible gooey texture.
- 1/4 cup grated Parmesan cheese: Offers a sharp, savory finish atop the creamy base.
- 1 cup cooked pasta or cooked rice (optional): Makes the dish heartier and perfect for a filling meal.
- 1/2 cup breadcrumbs (optional topping): Adds a crunchy golden topping when mixed with butter.
- 1 tablespoon melted butter: Used to crisp up the breadcrumb topping for added texture.
How to Make Creamy Chicken and Spinach Casserole Recipe
Step 1: Prepare the Aromatics
Begin by heating the olive oil in a large skillet over medium heat. Add the diced onion and cook until it’s soft and translucent, about 3 to 4 minutes. Then, toss in the minced garlic and stir for an additional 1 minute to release its fragrant aroma. This step lays the foundation for the casserole’s rich flavor and makes the dish irresistible from the very first bite.
Step 2: Combine the Casserole Ingredients
In a spacious bowl, bring together your cooked chicken, thawed and well-drained spinach, sautéed onion and garlic, and the creamy elements like cream of chicken soup, sour cream, and milk. Sprinkle in the Italian seasoning, salt, black pepper, and red pepper flakes if you’re using them. Stir in the mozzarella and Parmesan cheeses, which will melt beautifully during baking, creating layers of luscious creaminess. If you want to make the casserole more filling, gently fold in cooked pasta or rice right here.
Step 3: Assemble and Bake
Transfer the combined mixture into a greased 9×13-inch baking dish, spreading it out evenly so every spoonful has a perfect balance of ingredients. If you’re opting for a crunchy topping, mix the breadcrumbs with melted butter and sprinkle generously over the casserole. This little extra step results in a delightfully crisp golden crust. Pop the dish into a preheated 375°F oven and bake it for 25 to 30 minutes, until bubbly and beautifully browned on top.
Step 4: Rest Before Serving
After baking, give your casserole about 5 minutes to cool and set slightly. This rest time helps the flavors marry fully and makes it easier to portion onto plates. The casserole will be warm, creamy, and inviting — ready to become a fast favorite in your home.
How to Serve Creamy Chicken and Spinach Casserole Recipe
Garnishes
Fresh herbs like chopped parsley or basil provide a lovely pop of color and brighten the dish beautifully. A sprinkle of extra Parmesan or a grind of fresh black pepper can also add an elegant finishing touch. For a bit of zing, a drizzle of lemon juice or some red pepper flakes on the top can be inspiring.
Side Dishes
This casserole stands beautifully on its own but pairs wonderfully with simple green salads, roasted vegetables, or steamed broccoli for some extra nutrition and crunch. Garlic bread or crusty rolls also make perfect companions to soak up every last bit of creamy sauce.
Creative Ways to Present
Serve the casserole in individual ramekins for a charming personal touch at dinner parties or family gatherings. You can also top it with sliced avocado or a dollop of fresh Greek yogurt for a modern twist. For a lighter feel, layer your casserole over a bed of cauliflower rice or serve alongside a fresh tomato salad.
Make Ahead and Storage
Storing Leftovers
After enjoying your delicious casserole, store any leftovers in an airtight container in the refrigerator. It keeps well for up to 3 days, making it a perfect make-ahead meal for busy nights or quick lunches.
Freezing
This Creamy Chicken and Spinach Casserole Recipe freezes beautifully, so don’t hesitate to make a double batch. Freeze the unbaked casserole, tightly wrapped, for up to 3 months. When you’re ready, thaw it overnight in the fridge and bake as directed.
Reheating
Reheat portions in the microwave or oven until warmed through. Cover with foil to keep the moisture in if reheating in the oven. The creamy texture remains intact, and the cheese melts back to silky perfection, making leftovers just as inviting as the first serving.
FAQs
Can I substitute fresh spinach for frozen in this recipe?
Absolutely! Fresh spinach works wonderfully as long as you sauté and drain it to remove excess moisture before adding it. It adds a fresher flavor that’s delightful in this casserole.
Is it possible to use Greek yogurt instead of sour cream?
Yes, Greek yogurt is a fantastic substitution if you want to lighten up the dish without sacrificing creaminess. It also adds a subtle tang that complements the chicken and spinach nicely.
Can I make this casserole vegetarian?
You can! Replace the chicken with cooked mushrooms, tofu, or chickpeas, and use a cream of mushroom or vegetable soup instead of cream of chicken soup. It will still be rich and satisfying.
What are good alternatives to mozzarella and Parmesan cheese?
Cheddar, Monterey Jack, or Gruyère cheeses melt well and offer different flavor notes. For Parmesan alternatives, Pecorino Romano or Asiago provide a great sharpness.
How do I prevent the casserole from being too watery?
Make sure to drain the spinach thoroughly and avoid adding too much milk. Also, giving the casserole a few minutes to rest after baking helps it thicken for perfect serving consistency.
