Ingredients You’ll Need

Here are the exact quantities to ensure perfect results.

Main Ingredients

  • 2 pounds boneless, skinless chicken breasts, cooked and shredded or cubed
  • 8 ounces full-fat cream cheese, softened
  • 1 cup sour cream
  • 1 cup shredded mozzarella cheese
  • 1 cup shredded cheddar cheese
  • 3 cups fresh spinach, roughly chopped
  • 3 cloves garlic, minced
  • 1 small yellow onion, finely diced
  • 1 tablespoon olive oil
  • 1/2 cup chicken broth
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon paprika

Optional Add-Ins

  • 1/4 teaspoon red pepper flakes for gentle heat
  • 1/4 cup grated Parmesan cheese for extra richness

Step-by-Step Instructions

Step 1: Prepare the Oven and Dish

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish with olive oil or cooking spray to prevent sticking.

Step 2: Sauté Aromatics

In a large skillet over medium heat, add olive oil.
Add diced onion and cook for 3–4 minutes until soft and translucent.
Stir in minced garlic and cook for 30 seconds until fragrant.

Step 3: Wilt the Spinach

Add the chopped spinach to the skillet.
Cook for 2–3 minutes until it wilts down.
Remove from heat and set aside.

Step 4: Prepare the Creamy Base

In a large mixing bowl, combine:

  • Softened cream cheese
  • Sour cream
  • Chicken broth
  • Salt
  • Pepper
  • Italian seasoning
  • Paprika
    Mix until smooth and creamy.

Step 5: Combine Everything

Add shredded chicken to the bowl.
Fold in the sautéed spinach mixture.
Stir in half of the mozzarella and half of the cheddar cheese.
Mix thoroughly so everything is evenly coated.

Step 6: Assemble the Casserole

Transfer the mixture to your prepared baking dish.
Spread it evenly using a spatula.
Top with remaining mozzarella and cheddar cheese.
If using Parmesan, sprinkle it over the top.

Step 7: Bake

Bake uncovered for 25–30 minutes, or until bubbly around the edges and lightly golden on top.
Let it rest for 5–10 minutes before serving.

Tips for Perfect Texture and Flavor

  • Use room-temperature cream cheese for a smoother mixture.
  • Don’t overcook the chicken before baking. It will cook again in the oven.
  • Fresh spinach gives the best flavor, but frozen spinach works if thoroughly drained.
  • Let the casserole rest before serving to help it set properly.

Serving Ideas

This casserole pairs beautifully with:

  • Steamed broccoli
  • Garlic green beans
  • A simple side salad
  • Roasted cauliflower
  • Warm dinner rolls
    It’s also excellent on its own if you’re looking for a protein-rich main dish.

Frequently Asked Questions
