Green beans au gratin are a very simple and quick side dish to prepare.
They are suitable to accompany both meat and fish dishes.
They are also a rather light dish: in fact, little oil is used and they are only gratinated with a little grated Parmesan cheese and breadcrumbs so that a crispy crust forms.
Therefore, no béchamel sauce is used.
However, they remain very tasty and will appeal to everyone: adults and children.
Let’s see together how they are prepared.
