About Zucchini Gratin
Zucchini gratin, gratin de courgettes, is the summer-vegetable cousin in the French gratin repertoire, a way of turning an abundance of zucchini into something rich and golden. Sliced zucchini is baked under cream and Comté, the firm, fruity Alpine cheese that browns into a nutty crust, with garlic and thyme for backbone. The defining move here is softening the zucchini in oil first, with the garlic and thyme, to drive off its considerable water before it ever meets the cream. Skip that and the vegetable weeps into the dish; do it and the cream stays thick and the layers hold.
The result is tender, creamy, and savory, with the mild zucchini carrying the fragrance of thyme and the deep, toasted flavor of melted Comté across the top. Because zucchini is so low in starch, this gratin stays light enough to suit low-carb and keto eating while still delivering the comfort of a cream-and-cheese bake. It comes together in about 45 minutes and works as a side to grilled meat or fish, or as a vegetarian centerpiece with a crisp salad. A few minutes of rest before serving firms it up so it spoons out neatly rather than sliding apart.
