Rugbrød (Danish pronunciation: [ˈʁuˌpʁœðˀ]) is a very common form of rye bread from Denmark.[1][2]

Rugbrød usually resembles a long brown extruded rectangle, no more than 12 cm high, and 30–35 cm wide, depending on the bread pan in which it is baked. Ingredients typically include rye flour, cracked or chopped rye kernels and other seeds such as sunflower seeds, linseeds or pumpkin seeds. The dough may be made exclusively with rye and wheat flour or contain up to one third whole rye grains. Ale or beer can be substituted for some of the water component of a recipe.

Sourdough is almost always used for the base dough, as commercial yeasts are unsuitable. The naturally fermented dough will develop a Lactobacillus culture in symbiotic combination with naturally present yeasts. It is essential in baking rye-based breads because the chemistry of rye flour produces an environment that is acidic. The most commonly present yeast species in the production of naturally leavened dough is Saccharomyces exiguus, which is more acid-tolerant than commercially produced S. cerevisiae, although the latter and other strains may also be present. Research has shown that when creating a naturally fermented starter, any naturally present S. cerevisiae will have died off after a few days. Sourdough is thus a stable culture of lactic acid bacteria and yeast in a mixture of flour and water. The yeast produces carbon dioxide which leavens the dough, and the bacteria produces lactic acid which contributes flavor. The bacteria metabolizes sugars that the yeast cannot, and the yeast metabolizes byproducts of bacterial fermentation. Commercially produced yeast will not accomplish these processes in rye flour.

Rugbrød is almost always very low in fat, comparable to most other varieties of bread. It contains no added oils or fats. Additional flavourings, other than salt, can include barley malt syrup. The bread is rich in whole grain and dietary fiber and contains little or no sugar, and is thus considered by many Danes as a healthy alternative to white wheat breads.

Buttered rugbrød is essentially the base for Danish open sandwich smørrebrød.
