South Asian cuisine includes the traditional cuisines from the modern-day South Asian republics of Bangladesh, India, Maldives, Nepal, Pakistan and Sri Lanka, also sometimes including the kingdom of Bhutan and the emirate of Afghanistan. Also sometimes known as Desi cuisine, it has been influenced by and also has influenced other Asian cuisines beyond the Indian subcontinent.

Chapati, a type of flat bread, is a common part of meals to be had in many parts of the Indian subcontinent. Other staples from many of the cuisines include rice, roti made from atta flour, and beans.

Foods in this area of the world are flavoured with various types of chilli, black pepper, cloves, and other strong herbs and spices along with the flavoured butter ghee. Ginger is an ingredient that can be used in both savory and sweet recipes in cuisines from the subcontinent. Chopped ginger is fried with meat, and pickled ginger is often an accompaniment to boiled rice. Ginger juice and ginger boiled in syrup are used to make desserts. Turmeric and cumin are often used to make curries.

Common meats include lamb, goat, fish, chicken and beef. Beef is less common in India than in other South Asian cuisines because cattle have a special place in Hinduism. Prohibitions against beef extend to the meat of (water) buffalo and yaks to some extent. Pork is considered as a taboo food item by all Muslims and is not taboo but avoided by many Hindus, though it is commonly eaten in some regions like Northeast India and Goa. A variety of very sweet desserts which use dairy products is also found in cuisines of the Indian subcontinent. The main ingredients in desserts of the Indian subcontinent are reduced milk, ground almonds, lentil flour, ghee and sugar. Kheer is a dairy-based rice pudding, a common dessert.

Many foods from the subcontinent have been known for over five thousand years. The Indus Valley people, who settled in the northwestern Indian subcontinent, hunted turtles and alligator. They also collected wild grains, herbs and plants. Many foods and ingredients from the Indus period (c. 3300–1700 B.C.) are still common today. Some consist of wheat, barley, rice, tamarind, eggplant, and cucumber. The Indus Valley people cooked with oils, ginger, salt, green peppers, and turmeric root, which would be dried and ground into an orange powder.

Indians have used leafy vegetables, lentils, and milk products such as yogurt and ghee throughout their history. They also used spices such as cumin and coriander. Black pepper, which is native to India, was often used by 400 A.D. The Greeks brought saffron and the Chinese introduced tea. The Portuguese and British made red chili, potato and cauliflower popular after 1700 A.D. Mughals, who began arriving in India after 1200, saw food as an art and many of their dishes are cooked with as many as 25 spices. They also used rose water, cashews, raisins, and almonds.

In the late 18th and early 19th century, an autobiography of the Scottish Robert Lindsay mentions a Sylheti man called Saeed Ullah cooking a curry for Lindsay's family. This is possibly the oldest record of Indian cuisine in the United Kingdom.

Afghan cuisine is influenced by Persian, Central Asian, and Indian cuisines due to Afghanistan's close proximity and cultural ties. The cuisine is halal and mainly based on mutton, beef and poultry with rice and Afghan bread.
