Fideuà (fideuada) is a seafood dish originally from the coast of Valencia that is similar to paella, and even more so to arròs a banda, but with noodles instead of rice. Its main ingredients are pasta noodles (often hollow), fish, cuttlefish, squid, mussels, shrimp, crayfish, etc. It is seasoned mainly with lemon.
Just like paella, it is cooked in a special wide and flat frying pan, also called paellera, although there are other traditional variants made in a casserole. The pasta is sautéed in stock, rather than boiled.
