Traditional Czech food. Traditional Czech food is not exactly what one would call dietary, however it perfectly goes with the flavourful Czech beer. It mostly consists of pork or beef meat with sauce and a side dish, the most common and liked being dumplings.Dumplings (“knedliky”) are the Czech traditional side dish made from wheat or potato flour, boiled in water as a roll and then sliced and served hot.Other side dishes are: rice, potatoes (boiled, baked or fried).hicken, duck, turkey, fish, rabbit and lamb are also used in some very tasteful Czech dishes. A good choice can be the Gulaš (guláš read like In, “english“), goulash even though it basically belongs to Traditional hungarian. cuisine
