- Step 7: In a small bowl, mix the breadcrumbs with melted butter. Sprinkle this topping evenly over the casserole.
- Step 8: Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the breadcrumbs are golden brown.
- Step 9: Allow the casserole to rest for 5 minutes before serving to let it set slightly.

Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish to prevent sticking and ensure easy serving.
- Sauté Vegetables: In a skillet over medium heat, sauté chopped onion and garlic until they become soft and fragrant, about 3 minutes. Add chopped fresh spinach and cook until wilted, about 2 minutes. Drain any excess liquid from the mixture to avoid a soggy casserole.

- Prepare the Topping: Combine breadcrumbs with melted butter until the crumbs are evenly coated. Sprinkle this mixture over the top of the casserole to add a crisp, golden topping.
- Bake: Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the topping is golden brown.
- Rest and Serve: Remove from oven and let the casserole stand for 5 minutes to set before serving. This resting step helps the casserole hold its shape and enhances flavor melding.
Notes
- Using freshly shredded chicken enhances flavor and texture, but leftover rotisserie chicken works well too.
- For a lower-fat option, consider using reduced-fat cream cheese and sour cream.
- Spinach can be substituted with other greens like kale or Swiss chard as desired.
- To make it gluten-free, use gluten-free breadcrumbs or omit the breadcrumb topping.
- Feel free to add fresh herbs such as parsley or thyme for additional flavor.
- If you like it spicy, increase the red pepper flakes or add a pinch of cayenne pepper.
