This Zucchini-Gruyere Tart is a delicious and savory dish that combines the flavors of zucchini and Gruyere cheese. The tart has a flaky and buttery crust, topped with a creamy mixture of eggs, milk, and Gruyere cheese. Thinly sliced zucchini is then arranged on top, creating a beautiful and colorful pattern. The tart is baked until golden and the zucchini is tender. It is perfect for brunch, lunch, or as a light dinner option.
