Tom Yum Soup (Thai Soup)

Tom Yum Soup is a classic Thai hot and sour soup known for its fragrant broth infused with lemongrass, galangal, kaffir lime leaves, and Thai chilies. This recipe uses prawn shells and heads to create a rich, flavorful broth complemented by fresh prawns, mushrooms, tomato, and onion. The clear version highlights bright herbal and citrus notes, and an optional creamy variation incorporates evaporated milk and chili paste for a richer texture.

Description

Tom Yum Soup (Thai Soup) is built on a broth simmered with aromatic ingredients such as smashed lemongrass, garlic, galangal, kaffir lime leaves, and fresh Thai chilies. Using prawn heads and shells intensifies the seafood flavor of the broth. After simmering and straining, the broth is returned to the pot and finished with oyster mushrooms, onions, and tomatoes before adding the prawn meat. Seasoning with fish sauce, lime juice, and sugar creates the balanced sweet, sour, and salty profile essential to Tom Yum.

The soup’s texture is clear and broth-focused with tender prawns and soft vegetables providing bite. The optional creamy version adds Thai chili paste and evaporated milk, giving a milder heat and a richer mouthfeel. This flexible soup combines complex herbal flavors with seafood freshness.

This soup is typically served hot, garnished with fresh coriander and extra fresh chilies if desired. It works well as a light main course or appetizer. It can be reheated gently, adding seafood last to avoid overcooking. Fresh ingredients such as lemongrass and kaffir lime leaves enhance the authentic flavor but dried or paste substitutions work if fresh items are unavailable.

Frozen peeled prawns can be used for convenience, added late in cooking. The broth freezes well if strained and cooled separately from the seafood and vegetables, making it easy to prepare ahead.

Notes

  • Peel the lemongrass stalks to expose the softer bottom half for maximum flavor release.
  • If galangal is unavailable, substitute fresh ginger with a pinch of black pepper for similar spice notes.
  • Fresh kaffir lime leaves are preferable but dried leaves can be used in the same quantity.
  • The heat level is moderate; adjust the number of Thai chilies to taste.
  • Fish sauce is essential for authentic flavor, with no close substitute recommended.
  • Thai roasted chili paste adds depth; use sambal oelek plus chili oil if needed.
  • For a quick version, use frozen pre-peeled prawns, adding them near the end to prevent overcooking.
  • Leftover broth can be refrigerated for 2 days and reheated gently without seafood to retain flavor and texture.
