Livro de Cozinha da Infanta D. Maria de Portugal is the oldest known cookbook in Portuguese language. It is a manuscript from the 16th century that belongs to Infanta D. Maria of Portugal, the daughter of Infante D. Duarte and the granddaughter of King Manuel I of Portugal. She married Alessandro Farnese, Duke of Parma and Piacenza, in 1565 and took the manuscript with her to Italy. The manuscript is currently preserved in the National Library of Naples.

The cookbook contains 67 recipes that are divided into four sections: "Caderno dos Manjares da Carne" (Booklet of Meat Dishes), "Caderno dos Manjares de Leite" (Booklet of Milk Dishes), "Caderno dos Manjares de Ovos" (Booklet of Egg Dishes) and "Caderno das Cousas de Conservas" (Booklet of Preserves). The recipes reflect the medieval character of Portuguese cuisine at the time, with dishes made of meat, poultry, game, fish, eggs, milk, fruits, desserts and preserves. The use of sugar and spices, which were still scarce and luxurious goods, is prevalent in many recipes. Recommends
