🛒 Ingredients You’ll Need
Here’s what makes this casserole creamy, savory, and totally addictive:
Base Ingredients:
- 2 cups cooked chicken (shredded or cubed)
- 6 oz fresh spinach (or 1 cup frozen spinach, thawed and drained)
- 8 oz cream cheese, softened
- 1/2 cup sour cream or heavy cream
- 1/2 small onion, finely chopped
- 2 cloves garlic, minced
- 1 ½ cups shredded mozzarella
- ½ cup grated parmesan cheese
Optional Add-ins:
- ½ cup chopped mushrooms 🍄
- ¼ tsp crushed red pepper flakes 🌶️
- Chopped cooked bacon 🥓
- 1 cup cooked rice or cauliflower rice
- ¼ tsp nutmeg (for warmth)
Pantry Seasonings:
- Salt & pepper to taste
- 1 tsp Italian seasoning
- ½ tsp garlic powder
- 1 tbsp olive oil or butter

👩🍳 Step-by-Step Instructions
Here’s how you make it — in just 6 simple steps.
🔥 1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Grease a medium casserole dish (8×8 or 9×9 works well).
🧅 2. Sauté the Spinach and Aromatics
In a large skillet over medium heat, heat olive oil. Add the chopped onions and cook for 2–3 minutes until translucent. Add the garlic and cook another 30 seconds until fragrant.
Toss in the spinach and sauté until wilted (or just warmed through if using frozen). Set aside.

🍗 3. Make the Cream Cheese Mixture
In a large mixing bowl, combine:
- Softened cream cheese
- Sour cream or heavy cream
- 1 cup mozzarella
- Parmesan
- Cooked chicken
- Spinach mixture
- Seasonings (salt, pepper, garlic powder, Italian seasoning)
Mix until well combined and creamy.
🥘 4. Assemble the Casserole
Spread the mixture evenly in your prepared baking dish. Sprinkle the remaining ½ cup mozzarella on top. Add crushed red pepper or extra parmesan if desired.
⏲️ 5. Bake to Perfection
Bake for 25–30 minutes or until the top is golden and bubbling. Broil for 1–2 minutes at the end for a crispier top (optional but delicious).

🌿 6. Cool, Garnish & Serve
Let the casserole cool for 5–10 minutes before serving. Garnish with chopped parsley or fresh basil for color and freshness.
🥄 Serving Suggestions
