Ingredients You’ll Need
Here’s everything you need, with exact quantities to make sure it turns out perfectly every time.
Main Ingredients
- 2 cups cooked chicken breast, shredded or diced (about 2 large chicken breasts)
- 2 cups fresh spinach (or 1 cup frozen spinach, thawed and drained)
- 8 oz cream cheese, softened
- 1/2 cup sour cream
- 1/2 cup heavy cream
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
Flavor Base
- 3 cloves garlic, minced
- 1 small onion, finely chopped
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika
- 1/2 teaspoon Italian seasoning
Optional Add-Ins
- 1/2 teaspoon red pepper flakes for a slight kick
- 1/2 cup mushrooms, sliced
- 1/4 cup chopped sun-dried tomatoes
Step-by-Step Instructions
Follow these steps carefully and you’ll get a perfectly creamy casserole every time.
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a baking dish to prevent sticking.
Step 2: Cook the Aromatics
In a large skillet, heat olive oil over medium heat. Add chopped onion and cook for 3 to 4 minutes until soft.
Add minced garlic and cook for another 30 seconds until fragrant.
Step 3: Add Spinach
Add the fresh spinach to the skillet. Cook until wilted, about 2 to 3 minutes. If using frozen spinach, make sure it’s fully drained before adding.
Step 4: Create the Creamy Base
Lower the heat and add cream cheese, sour cream, and heavy cream. Stir until everything melts into a smooth, creamy mixture.
Season with salt, pepper, paprika, and Italian seasoning.
Step 5: Combine Chicken
Add the cooked chicken to the skillet and mix well so it’s fully coated in the creamy sauce.
Step 6: Assemble the Casserole
Transfer the mixture into your prepared baking dish. Spread evenly.
Top with mozzarella and Parmesan cheese.
Step 7: Bake
Bake uncovered for 20 to 25 minutes, until the top is golden and bubbling.
Step 8: Rest and Serve
Let the casserole sit for 5 minutes before serving. This helps everything set and makes it easier to scoop.
A Little Kitchen Insight That Makes a Difference
Sometimes, the smallest tweaks make the biggest impact. One evening, I tried sautéing the spinach just a bit longer than usual, letting some of the moisture cook off completely. The result? A thicker, richer casserole that didn’t feel watery at all.
It’s one of those little habits I’ve kept ever since.
