Strata is a family of layered casserole dishes in American cuisine.
The most common modern variant is a brunch dish, made from a mixture which mainly consists of bread, eggs and cheese.
It was popularized in the 1984 Silver Palate Good Times Cookbook by Julee Rosso and Sheila Lukins.
[2][3] Other recipes merely require that the ingredients are mixed together, like a savory bread pudding.
A beaten egg mixture is then poured over the ingredients.
