Our spinach gratin recipe is how spinach was meant to be consumed—with lots of cheese! We perfected this recipe so it’s not ‘soupy’ like au gratin dishes you may have tasted in the past. In fact, we added just enough sauce to bind and flavor the spinach and used a nice, high-quality Monterey Jack or Gruyere cheese.
This gratin will convert those wary-of-green-vegetable eaters to greens lovers. A simple white sauce lightly coats Swiss chard leaves, and a topping of cheese and crisp breadcrumbs seals the deal. For a different presentation, bake in individual gratin dishes or ramekins rather than one large dish. Make up to a day ahead and keep in the fridge until ready to serve.
