Korean cuisine originated from ancient agricultural and nomadic traditions in the Korean peninsula and southern Manchuria, and has evolved through a complex interaction of environmental, political, and cultural trends.

Korean cuisine is largely based on rice, noodles, tofu, vegetables, and meats. Traditional Korean meals are noted for the number of side dishes (banchan) that accompany steam-cooked short-grain rice. Kimchi is usually served at every meal. Commonly used ingredients include sesame oil, doenjang (fermented bean paste), soy sauce, salt, garlic, ginger, pepper flakes and gochujang (fermented red chili paste).
Ingredients and dishes vary by province. Many regional dishes have become national, and dishes that were once regional have proliferated in different variations across the country. The Korean royal court cuisine once brought all of the unique regional specialties together for the royal family. Meals are regulated by Korean cultural etiquette.

The Three Kingdoms period (57 BCE – 668 CE) was one of rapid cultural evolution. The kingdom of Goguryeo (37 BCE – 668 CE) was located in the northern part of the peninsula along much of modern-day Manchuria. The second kingdom, Baekje (18 BCE – 660 CE), was in the southwestern portion of the peninsula, and the third, Silla (57 BCE – 935 CE), was located at the southeastern portion of the peninsula. Each region had its own distinct set of cultural practices and foods. For example, Baekje was known for cold foods and fermented foods like kimchi. The spread of Buddhism and Confucianism from China during the fourth century CE began to change the distinct cultures of Korea.

The Three Kingdoms were followed by the Unified Silla period (668 CE – 935 CE), during which Silla unified most of the southern region of Korea, while the Northern region was unified by refugees from Goguryeo who renamed the region Balhae. These cultures adhered to the beliefs of Buddhism with a moderate level of peaceful coexistence. During the tenth century, however, both cultures began to erode and were eventually unified under the Goryeo dynasty, which drew much of its culture from the Song Dynasty of China. It was this dynasty that introduced the peninsula to the Western world and it is from the word "Goryeo" that the country's modern name of "Korea" was derived.
During the latter Goryeo period, the Mongols invaded Korea in the 13th century. Although there was a vast loss of life in Korea, some traditional foods found today in Korea have their origins in the Mongol invasion. The dumpling dish, mandu, grilled meat dishes, noodle dishes, and the use of seasonings such as black pepper, all have their roots in the this period.
