Köttbullar are traditional Swedish meatballs made from ground meat, typically a mix of beef and pork. They are seasoned with ingredients like onion, salt, and pepper, and often include breadcrumbs or flour to bind the mixture. Köttbullar are usually shaped into small balls and then fried or baked until golden brown. These meatballs are commonly served with lingonberry sauce and creamy gravy, alongside mashed potatoes or boiled potatoes. Köttbullar are a popular dish in Sweden and are often enjoyed during festive occasions, as well as in everyday meals. They have also gained international popularity, especially in Swedish restaurants and IKEA stores.
