Start by washing and slicing the zucchini into thin rounds. Chop the basil and zest the lemon carefully. Having everything ready beforehand makes the process smooth and quick.
In a large bowl, whisk together the eggs and milk or cream until fully combined. Season with salt and pepper to enhance the flavor. This mixture forms the creamy base of your quiche.
Stir in the zucchini, corn, goat cheese, basil, and lemon zest. Mix gently so everything is evenly distributed. The combination creates a balance of creamy, fresh, and slightly tangy flavors.
Pour the mixture into a greased 9-inch pie dish. Spread the ingredients evenly to ensure consistent cooking. This step helps the quiche bake uniformly.
Place the dish in a preheated oven at 375°F (190°C). Bake for about 25–30 minutes until the top is lightly golden and the center is set.
Let the quiche cool for a few minutes before slicing. This helps it firm up and makes serving easier. Enjoy it warm or at room temperature.
