Step-by-Step Instructions
Step 1: Prepare the Ingredients
- Cook and shred your chicken if it’s not pre-cooked.
- If using fresh spinach, sauté it lightly until wilted. For frozen spinach, thaw and drain well.
Step 2: Make the Sauce
- In a mixing bowl, combine cream cheese, sour cream, garlic, onion, and seasonings. Stir until smooth and well-blended.
Step 3: Assemble the Casserole
- Preheat your oven to 375°F (190°C).
- In a greased casserole dish, layer the shredded chicken, sautéed spinach, and creamy sauce. Mix gently to combine.
Step 4: Add Cheese and Bake
- Sprinkle mozzarella and Parmesan cheese evenly on top.
- Bake uncovered for 25-30 minutes, or until the top is golden and bubbly.
Step 5: Serve and Enjoy
- Let the casserole cool slightly before serving. Pair with a fresh salad, crusty bread, or rice for a complete meal.

Tips for the Best Casserole
- Use Freshly Grated Cheese: It melts better and gives a richer flavor compared to pre-shredded varieties.
- Avoid Overcooking the Chicken: Keep the meat moist and tender for the best texture.
- Drain Spinach Well: If the spinach holds too much water, it can make the casserole soggy.
- Try a Crunchy Topping: Add breadcrumbs or crushed crackers for extra texture.
Variations and Customizations
- Vegetarian Option: Swap chicken for tofu or a plant-based alternative.
- Add Pasta: Incorporate cooked pasta to make it a heartier dish.
- Extra Veggies: Zucchini, broccoli, or bell peppers work wonderfully.
- Cheese Choices: Experiment with Gruyère, cheddar, or provolone for a unique flavor.

Tastes great! I sautéed onions, mushrooms & garlic, then added the fresh spinach before mixing in chicken and sauce.
Thanks for the feedback! So glad you enjoyed it:)
This is such a great recipe. I swapped Greek yogurt for sour cream and neuchatel for the cream cheese to lighten things a little. I also added broccoli and sautéed red pepper. My husband loved it and so did I.
Thank you! Happy you loved it!
Trying this tonight. But gotta add chopped bacon!
Thanks for trying! Hope you’ll love it:)
