Bigos (Polish pronunciation: [ˈbʲiɡɔs] ^ⓘ), often translated into English as hunter's stew, is a Polish dish of chopped meat of various kinds stewed with sauerkraut, shredded fresh cabbage and spices. It is served hot and can be enriched with additional vegetables and wine. Originally from Poland, the dish also became traditional in the areas of the vast Polish–Lithuanian Commonwealth.

The Polish word bigos is probably of Italian or German origin, but its exact etymology is disputed. According to the Polish loanword dictionary edited by Elżbieta Sobol, it may derive from German begossen, meaning "doused" or "basted". Jerzy Bralczyk similarly derives the word from archaic German Beiguss, "sauce". Aleksander Brückner has proposed the German Bleiguss, "piece of lead", as a possible source, referring to a tradition of divining from strangely shaped flakes of molten lead dropped into water. Maria Dembińska rejects this etymology as "doubtlessly erroneous", suggesting instead either archaic German becken, "to chop", or old German bîbôz (Beifuss in modern German), meaning "mugwort" (Artemisia vulgaris), a herb that was popular in medieval cuisine. Andrzej Bańkowski also points to the Italian bigutta, or "pot for cooking soup", as a possible derivation via German.

The principal ingredients of bigos are assorted kinds of meat chopped into bite-sized chunks and a mixture of sauerkraut and shredded fresh white cabbage. The meats may include pork (such as ham, shoulder, bacon, ribs, and loin), beef and veal, poultry (chicken, duck, goose, turkey) and game, as well as charcuterie, especially various kinds of kiełbasa. The variety of meats is considered essential for good bigos; its preparation may be a good occasion to clean out one's freezer and use up leftovers from other meat dishes. Some of the meats may be roasted before being diced together with other cuts of meat and braised in lard or vegetable oil.

The sauerkraut is often rinsed and drained before being chopped and mixed with shredded fresh cabbage. The proportion depends on the sauerkraut's maturity; the longer it has cured, the more sour it tastes, calling for more fresh cabbage to balance the flavor. Traditionally, cabbage was pickled in fall, so bigos made at that time could be made with only half-cured sauerkraut, but by early spring, the sauerkraut had to be combined in equal parts with fresh cabbage. The mixture is precooked in a small amount of water before being mixed with the braised meat and left to simmer for several hours. Ideally, the stew should thicken through evaporation alone, but flour, roux, crumbled rye bread or a grated raw potato may be added to it to take up excess moisture.

Other ingredients often added to bigos include onions, diced and browned in lard together with the meat, and dried forest mushrooms that are precooked separately in boiling water. The stew is usually seasoned with salt, black peppercorns, allspice, juniper berries and bay leaves. Some recipes also call for caraway, cloves, garlic, marjoram, mustard seeds, nutmeg, paprika and thyme. The tart flavor of sauerkraut may be enhanced by adding some dry red wine or beet sour (fermented beetroot juice that is also a traditional ingredient of borscht), which may impart a reddish hue to the stew. Bigos is often slightly sweetened with sugar, honey, raisins, prunes or plum butter known in Polish as powidła.

Traditionally, bigos is stewed in a cauldron over an open fire or in a large pot on a stove, but it may also be prepared in an electric slow cooker. The contents should be stirred from time to time, to prevent scorching, which may impart a bitter taste to the entire batch. Bigos is considered best after it has been repeatedly refrigerated and reheated to allow the flavors to fuse.

The flexible and forgiving recipe for bigos allows a great number of variants, often simply using what ingredients are at hand. It is often claimed that there are as many recipes as there are cooks in Poland.

In the region of Greater Poland, bigos typically contains tomato paste and is seasoned with garlic and marjoram. Kuyavian bigos is often made from red cabbage as well as white. In Silesia, it is usually mixed with kopytka or kluski, that is, small plain boiled dumplings made from unleavened dough that contains flour and mashed potatoes. A variant which contains julienned apples, preferably with a winey tart taste, such as Antonovka, is known as Lithuanian bigos and is typical for the territory of the erstwhile Grand Duchy of Lithuania (now Belarus, Lithuania and Ukraine).
