This skillet zucchini gratin is a dish that is both simple to prepare and visually appealing, perfect as a satisfying side or even a light meal. Thinly sliced zucchini rounds are carefully layered with a creamy ricotta cheese, providing a smooth and delicate base. The addition of salty, aged cheese adds a sharp, savory counterpoint that elevates the overall flavor profile.

A rosemary-infused heavy cream sauce is generously poured over the zucchini and cheese layers, melding the ingredients together and creating a rich, decadent texture. The zucchini is pre-salted to draw out excess moisture, ensuring that the gratin maintains a delightful consistency, avoiding any sogginess. As it bakes, the top layer turns a beautiful golden brown, with the edges becoming slightly crisp and caramelized.

The aroma of rosemary permeates the dish, adding an herbaceous note that complements the earthiness of the zucchini and the richness of the cheese. Feel free to experiment with other herbs, such as thyme or sage, to customize the flavor to your liking. Different cheeses like parmesan or mozzarella can also be substituted for a personalized touch, each bringing its own unique character to the gratin.

If you don't have a mandolin, a sharp knife and a steady hand will work just as well to achieve those thin, even slices. This gratin makes an excellent side dish, complementing a variety of main courses. It pairs beautifully with roasted chicken, grilled steak, or even baked fish, adding a touch of elegance to any meal.

The combination of textures and flavors makes it a crowd-pleaser, sure to impress both family and friends. Serve it warm, allowing the creamy sauce to envelop each bite, and enjoy the harmonious blend of simple ingredients transformed into something truly special.
