Traditionally associated with Porto, francesinha is a unique sandwich consisting of toasted bread, beef or pork, sausages, ham, and cheese, while the whole combination is then doused in a rich beer-infused tomato sauce. The sandwich has different variations that include mushrooms, chicken, or vegetables.

Francesinha is not a sandwich you can enjoy on the go or as a quick snack; it is a wholesome meal that is usually found on the menus of traditional restaurants where it is served as a nutritious lunch or dinner.

Cod-based dishes are a Portuguese staple, and it is often suggested that there are more than one thousand recipes in which dried and salted cod is the star ingredient. This includes simple, everyday dishes, as well as more elaborate versions that are usually served on special occasions, including Christmas Eve and Good Friday.

Interestingly, cod is traditionally not caught off the Portuguese coast, but it became a prominent ingredient in the traditional cuisine during the exploration era because it could be stored for longer periods. Salted cod is primarily soaked in water, and later it can be used in a variety of ways, which include grilling, cooking, frying, or braising. 

Traditionally prepared for every Christmas Eve dinner in Portugal, bacalhau à Gomes de Sá is a festive dish made with salt cod, potatoes, and onions. Those key ingredients are layered in a pan, topped with hard-boiled egg slices, baked, then garnished with olives and chopped parsley.

The dish is typically dressed with olive oil and flavored with chopped garlic. It is believed that the dish was invented by José Luis Gomes de Sá, who was the son of a well-off 19th-century cod trader. The new dish was derived from bolinhos de bacalhau (cod fish cakes), only without the flour, so José, who had financial difficulties at the time, sold the recipe to the owner of Restaurante Lisbonense, and the dish quickly gained popularity throughout Portugal.

This clam-shaped Portuguese delicacy is made with a puff pastry shell that is filled with a unique mixture of minced veal, bread, and onions. The tradition of preparing pastel de Chaves dates back to 1862, and according to a popular legend, the first person to sell these unique pastries was Teresa Feliz Barreira, the founder of Casa do Antigo Pasteleiro, the first establishment where pastel de Chaves could be bought.

The original recipe stayed in her possession for 75 years, until the 1940s, when other bakeries in Chaves started to manufacture and sell the same product. The Portuguese city of Chaves protected this famous pastry as their authentic product, which licensed them to be the only location where pastel de Chaves can be produced and sold. 

This traditional tripe stew is a signature dish of Porto, a city whose citizens are even nicknamed tripeiros because of their love for tripe. The dish typically consists of veal tripe, white beans, smoked ham and pork sausage, pork or calf knuckles, carrots, onions, various spices such as paprika and cumin, and different cuts of pork and chicken.

Though numerous legends describe the invention of the dish, the most popular one claims that when Henry the Navigator went to conquer Ceuta, the locals supplied him with all the meat except tripe, which they then used to create this rustic stew. From the 15th century, the dish evolved into an iconic dish that is a staple in traditional restaurants in Porto.

In the north, the steaks are simmered in a spicy broth that is usually drizzled on the bread roll. Bifana is traditionally consumed without additional condiments, but it is occasionally accompanied by sautéed onions. In Lisbon, the meat is sometimes marinated and grilled, while mustard is a common accompaniment in Lisbon and in the south of Portugal.
