Thai food is known for its enthusiastic use of fresh (rather than dried) herbs and spices as well as fish sauce.

Thai food is popular in many Western countries especially in Australia, New Zealand, some countries in Europe such as the United Kingdom, as well as the United States, and Canada.

Instead of a single main course with side dishes found in Western cuisine, a Thai full meal typically consists of either a single dish or rice khao with many complementary dishes served concurrently.

Rice is a staple component of Thai cuisine, as it is of most Asian cuisines. The highly prized, sweet-smelling jasmine rice is indigenous to Thailand. This naturally aromatic long-grained rice grows in abundance in the verdant patchwork of paddy fields that blanket Thailand's central plains. Its aroma bears no resemblance to the sweet smell of jasmine blossoms, but like jasmine flowers, this rice is precious and fragrant, a small everyday delight. Steamed rice is accompanied by highly aromatic curries, stir-frys and other dishes, incorporating sometimes large quantities of chillies, lime juice and lemon grass. Curries, stir-frys and others may be poured onto the rice creating a single dish called khao rad gang , a popular meal when time is limited. Sticky rice khao neow is a unique variety of rice that contains an unusual balance of the starches present in all rice, causing it to cook up to a pleasing sticky texture. It is the daily bread of Laos and substitutes ordinary rice in rural Northern and Northeastern Thai cuisine, where Lao cultural influence is strong.

Noodles, known throughout parts of Southeast Asia by the Chinese name kwaytiow, are popular as well but usually come as a single dish, like the stir-fried Pad Thai or noodle soups. Many Chinese cuisine are adapted to suit Thai taste, such as khuaytiow rue, a sour and spicy rice noodle soup.

There is uniquely Thai dish called nam prik which refers to a chile sauce or paste. Each region has its own special versions. It is prepared by crushing together chillies with various ingredients such as garlic and shrimp paste using a mortar and pestle. It is then often served with vegetables such as cucumbers, cabbage and yard-long beans, either raw or blanched. The vegetables are dipped into the sauce and eaten with rice. Nam prik may also be simply eaten alone with rice or, in a bit of Thai and Western fusion, spread on toast.

Thai food is generally eaten with a fork and a spoon. Chopsticks are used rarely, primarily for the consumption of noodle soups. The fork, held in the left hand, is used to shovel food into the spoon. However, it is common practice for Thais and hill tribe peoples in the North and Northeast to eat sticky rice with their right hands by making it into balls that are dipped into side dishes and eaten. Thai-Muslims also frequently eat meals with only their right hands.

Often thai food is served with a variety of spicy condiments to embolden the dish. This can range from dried chili pieces, sliced chili peppers in rice vinegar, to a spicy chili sauce such as the nam prik mentioned above.
