Spinach quiche is a savory dish made with a pastry crust filled with a mixture of eggs, cream, and fresh spinach. It often includes cheese, such as feta or Swiss, and can be seasoned with herbs and spices for added flavor. This dish is popular for breakfast, brunch, or as a light lunch. The preparation involves blind-baking the crust before adding the filling, which is then baked until set. Spinach quiche is versatile and can be customized with other ingredients like mushrooms, onions, or bell peppers. It is enjoyed warm or at room temperature.
