Instructions

Preheat your oven to 375°F (190°C). Lightly grease a baking dish and set aside.

Add cooked chicken to the skillet with spinach and gently mix.
Pour the cream mixture over the chicken and spinach, stirring until evenly coated.

Flavor Tips for the Best Casserole

Use freshly cooked chicken for the most tender texture.
Don’t overcook the spinach before baking — it will finish cooking in the oven.
Season in layers to ensure the sauce isn’t bland.
Let it rest after baking so the sauce thickens slightly.
