Bruna bönor och fläsk is a traditional dish made with a combination of brown beans, salt, vinegar, sugar, pork belly, butter, and potatoes. The beans are boiled until tender, then seasoned with sugar and vinegar. The pork belly is fried until browned and slightly crispy, and all of the components of the dish are done.

The brown beans are served with fried pork belly, and the dish is traditionally accompanied by boiled potatoes. Bruna bönor och fläsk can also be prepared with meatballs instead of the pork belly, if desired.
