What each ingredient does

Sweet potatoes

Form the bulk of the casserole, providing the soft body and main flavor.

Egg

Binds the mashed sweet potatoes so the casserole sets when baked.

Flour

Thickens the brown sugar topping so it bakes into a crumbly layer.

Butter

Adds richness and helps the topping brown and crisp.

Brown sugar

Melts into the topping, adding sweetness and caramel-like flavor.
