This Black Olive Quiche is a savory, custard-style pie made with eggs, cream, cheese, and black olives nestled in a flaky pie crust. Popular in mid-century entertaining, it combines the sharp tang of mustard and Monterey Jack cheese with the rich creaminess of eggs and heavy cream, balanced by the briny bite of sliced black olives. Likely served at luncheons or as an elegant brunch centerpiece, this recipe reflects a blend of comfort and sophistication from a time when quiche was an exotic yet accessible dish for home cooks.
