This recipe offers a simple approach to making a quick quiche using a premade crust. Combining eggs, dairy, cheese, spinach, and seasonings, the filling is poured into the crust and baked until golden and set, perfect for a fast breakfast or brunch.
Ensure frozen spinach is thoroughly thawed and squeezed dry to prevent a watery quiche filling. The mayonnaise may seem unusual, but it contributes richness and helps the quiche set beautifully; don't substitute it unless familiar with alternative bindings. Season the mixture generously with salt and garlic powder, tasting as you go. Quiche is done when the center is set and no longer liquid or excessively jiggly. Allow it to rest for 10-15 minutes after baking before slicing for cleaner portions.
