A weeknight when everyone is tired, or a Sunday lunch with no great ambition. The hard-boiled egg gratin with béchamel is made for those moments. Simple, comforting, economical — and honestly much better than you think before you make it.

What comes out of the oven is a surface golden like light caramel, with a few bubbles still crackling on the edges. Underneath, the béchamel has stayed creamy, almost liquid in spots, and the eggs have absorbed all that richness during baking. It smells like melted cheese mixed with nutmeg — a low, warm, deeply familiar scent. A dish with nothing to prove.
