Tom Yum Thai soup is the most popular recipe of all Thai soups, and it's famous worldwide. It usually includes shrimp (known as Tom Yum Goong), but a vegetarian version is just as satisfying. The hot and sour soup is filled with aromatic ingredients that combine for a healthy dish. You'll love how it warms and energizes!

The authentic Tom Yum recipe does not include coconut milk. However, some people prefer it with this ingredient (technically making it Tom Khaa soup) because it creates a thicker, richer tasting soup. In this recipe, coconut milk is an optional ingredient—if you decide to omit it, add a little more stock. In Thailand, they often use evaporated milk, which is a good option for vegetarians, while vegans will prefer to use coconut milk.

This vegetarian/vegan version uses soft tofu as the protein. It is quick and easy to make, and just as healthy than the traditional recipe. It works well as an appetizer, for lunch, or as part of a nutritionally complete dinner.

How to Adjust the Soup to Taste

When taste-testing, use the recipe's ingredients to make adjustments:

  • Add more chili or chili sauce if it's not spicy enough.
  • If it's not salty enough, add a little more soy sauce, stock, or salt.
  • Add 1 teaspoon of sugar if the soup is too sour.
  • When it's too salty or sweet, add another squeeze of lime juice.

Tips

  • Lemongrass, makrut lime leaves, galangal, and bok choy are available at Asian food markets.
  • When making the stock from cubes or powder, make it strong (if it tastes good on its own, it will make a better soup).
  • Tom Yum broth cubes are available and easiest to find at Asian markets. They include a few of the flavoring ingredients—typically chile, soy sauce, lemongrass, and citrus leaf, though they often also contain MSG. These make a nice stock base but it's still best to at least add the lime leaves, chilies, and galangal to flavor the soup.
  • For a gluten-free diet, look for wheat-free soy sauce.

Recipe Variations

The nice thing about this soup is that many of the ingredients can be substituted:

  • Use or faux chicken stock instead of vegetable.
  • Substitute minced lemongrass with 3 to 4 tablespoons of frozen prepared lemongrass.
  • Instead of red chilies, use 1/2 teaspoon dried crushed chili or 1 to 2 teaspoons chili sauce.
  • Baby bok choy can be replaced with chopped broccoli or bell pepper.

Is Tom Yum Soup Healthy?

In general, Thai cuisine is considered some of the healthiest food you can eat. Tom Yum soup is often touted as one of the best and it is commonly eaten for cold and flu relief. Nutritionally, the soup is low in calories, fat, and carbohydrates. Each individual ingredient brings its own benefits to the mix as well. For instance, tofu is an excellent vegetarian source of protein and lemongrass has antimicrobial and anti-inflammatory properties. Additionally, makrut lime leaves and galangal are good for digestion, and chili peppers can help with inflammation and improve immunity. While coconut milk will increase the soup's saturated fats, it is also filled with nutrients like calcium and protein.
