A close-up of a homemade sweet potato casserole in a white ceramic baking dish. The vibrant orange sweet potato mash peeks through where a scoop was taken, beneath a golden-brown pecan-oat streusel layer and perfectly toasted mini marshmallows with light tan tops. The edges of the dish show bits of melted marshmallow and crumb topping, all lit by warm, natural kitchen light.
