At first sip of this Thai tom yum soup, you'll be overcome by the intoxicating flavors of lemongrass, garlic, lime, coconut milk, and chile combined with a chicken stock base and topped off with shrimp. If you like spice, we recommend either fresh red chiles or getting yourself a bottle of chile oil and adding anywhere from a few drops to a few teaspoons. Or leave the chile out for a terrific mild tom yum.

Serve tom yum soup as is for a flavorful appetizer or with steamed white rice or sticky rice as a main dish. You can either place some rice in a bowl and serve the soup on top or serve the rice on the side.

Tip

  • While they can be messy to remove while eating, leaving the shells on shrimp adds infinitely more flavor to the soup. In Thailand, cooks sometimes remove the shells before cooking but add them to the soup, removing just before eating.

Recipe Variations

  • If you want to add some spice to your tom yum soup, we recommend adding chile oil, fresh chile, or chile flakes.
  • If this tom yum soup is too sour for your taste, add a little brown sugar.
  • If it turned out too salty, add a squeeze of lime juice.
  • Add more coconut milk if you want your soup richer/creamier or if it's too strong for your taste.

What Is the Difference Between Tom Kha and Tom Yum?

Tom kha is another classic Thai soup made with fragrant broth. Tom kha typically contains chicken and almost always includes coconut milk, while tom yum usually includes shrimp and can be made without coconut milk.

Is Tom Yum Soup Healthy?

Flavored with aromatics and filled with vegetables and lean shrimp, tom yum is a healthy option for lunch or dinner. To make this soup lighter, use low-fat coconut milk or omit it altogether. More vegetables can also be used in place of the shrimp. Use low-sodium soy sauce to reduce the amount of salt.
