Tom yum and tom kha: the two Thai soups to start with

Tom yum is sharp, sour and hot. Lemongrass, galangal and kaffir lime leaf give it a perfumed edge, and chili brings the heat. Prawns are the classic choice, so seafood lovers can also browse our Thai Seafood Dishes: What to Order and How They Taste.

Tom yum comes in two styles. Nam sai is the clear version, light and brothy. Nam khon is the creamy version, with a richer, rounder body. Both stay hot and sour.

Tom kha gai swaps the sharp bite for coconut milk. Chicken simmers with galangal and lemongrass in a creamy, tangy broth. Heat is usually gentler than tom yum, which makes it a safe first order. Coconut-based dishes overlap with the dishes covered in our guide to Types of Thai Curry: Green, Red, Massaman and More.

Other Thai soups worth ordering

Beyond the big two, several bowls reward a detour. Each one below suits a different mood and appetite.

  • Kaeng jued: a clear, mild soup, often with minced pork, tofu and soft vegetables. It is the gentlest bowl on this list.
  • Gaeng liang: a peppery vegetable soup, often with prawn or pork. Expect a savory, earthy flavor rather than coconut.
  • Kuay teow reua: boat noodle soup, famously served around Bangkok's Victory Monument. Bowls are small and dark with a deep, savory broth. Order a few to compare.
  • Khao soi: the Chiang Mai noodle soup. Egg noodles sit in a coconut curry broth, usually topped with crispy noodles.
  • Jok: rice porridge, popular as a morning meal. See our guide to Thai Breakfast: 8 Dishes and How to Order Them for more early options.

How to order soup in Thailand

Most soups arrive in an individual bowl, though tom yum often comes in a shared pot at sit-down restaurants. Order a plate of steamed rice alongside. Our guide to Thai Rice Dishes: What to Order in Thailand explains the options.

Tell the server how much heat you want. Say you prefer it mild, or ask for less chili. Street stalls cost the least, and food courts sit in the middle. Sit-down restaurants charge most. For a polished dining room, browse the Michelin Guide Thailand listings.

Lemongrass stalks, galangal slices and kaffir lime leaves usually stay in the bowl. They flavor the broth and are not meant to be eaten. Push them aside with your spoon. Use the spoon for broth and a fork to guide food onto it. Chopsticks are for noodle soups.

Dietary and allergy notes for Thai soups

Many Thai soups use fish sauce for seasoning. Some include shrimp paste, chicken stock or coconut milk. A bowl that looks vegetable-only may still contain fish sauce. Shellfish is common in tom yum, so say so clearly if you have an allergy.

Vegetarian and halal diners should ask the vendor directly how the broth is made. Our list of Thai Vegetarian Dishes: What to Order and What to Check helps with other meal choices. Tom yum is dairy-free in its clear form. The creamy version may contain milk, so ask before ordering.

Where soup fits in a Thai meal

Soup is usually not a starter course. It lands on the table with the other dishes and is shared around rice. Tom yum often sits beside a curry, a stir-fry and a salad. For smaller plates before the main dishes, see our Thai Appetizers: 10 Classic Starters and Ordering Tips guide. Noodle soups, such as boat noodles and khao soi, work as a complete single-bowl meal.

How to choose a Thai soup

Pick by heat first, then by richness. These shortcuts help at the table.

  • Want it spicy: order tom yum nam sai.
  • Want it rich and spicy: order tom yum nam khon.
  • Want no chili at all: try kaeng jued, or browse our Mild Thai Dishes: What to Order If You Can't Handle Spice.
  • Coconut-free: choose clear tom yum, kaeng jued or gaeng liang.
  • First-timer: order tom kha gai.
  • Mistake to avoid: eating the lemongrass, galangal or lime leaf.
  • Mistake to avoid: assuming every soup is mild.
  • Mistake to avoid: assuming a vegetable bowl is free of fish sauce.
