Tom Yum Soup is an iconic Thai hot and sour soup celebrated worldwide for its vibrant, aromatic broth and invigorating balance of fiery, citrusy, and savory flavors.
Originating in the central plains of Thailand, where freshwater fish and fragrant herbs thrive along riverbanks, Tom Yum has a history deeply intertwined with traditional Thai culinary and medicinal practices. The name itself reflects its core components: tom refers to the boiling process, while yum signifies the distinct spicy and sour salad-style flavor profile. Historically, it evolved from simple, peasant-style herbal broths into a royal palace dish, eventually becoming a global symbol of Thai gastronomy.
Culturally, Tom Yum is much more than a comforting meal; it is a pillar of Thai hospitality and wellness culture. In traditional Thai households, soups like this are often prepared using fresh, garden-grown herbs with the understanding that food serves as medicine. The combination of pungent roots, leaves, and citrus is traditionally believed to stimulate digestion, warm the body, and clear the sinuses, making it a classic remedy for seasonal colds.
Ingredients Quantity
- Broth: 4 cups chicken or vegetable broth
- Aromatics: 1 stalk lemongrass (cut into 3-inch pieces and smashed), 3-4 kaffir lime leaves (torn), 1-inch piece of galangal or ginger (sliced), 3-4 Thai bird’s eye chilies (smashed)
- Protein & Vegetables: 8-10 large shrimp (peeled and deveined) or firm tofu, 1 cup straw mushrooms or button mushrooms (halved)
- Seasonings & Finish: 2-3 tablespoons nam pla (fish sauce), 3 tablespoons fresh lime juice, 1-2 tablespoons nam phrik phao (Thai chili paste), 2 tablespoons fresh cilantro leaves (chopped)
Optional Additions
- Coconut milk: 1/2 cup to transform the broth into Tom Yum Nam Khon (creamy style)
- Cherry tomatoes: 5-6 halved, added toward the end for sweetness and color
- Culantro (sawtooth coriander): A traditional alternative or supplement to cilantro
- Sweet basil leaves: For an extra layer of herbal aroma
Tips for Success
- Smash the lemongrass, galangal, and chilies thoroughly with the back of a knife or pestle before adding them to release their essential oils.
- Never boil the lime juice; always add it off the heat at the very end to prevent it from turning bitter and to preserve its bright, fresh aroma.
- Do not overcook the shrimp; drop them in just before serving, and remove the pot from the heat as soon as they turn pink and opaque.
- The woody lemongrass stalks, galangal slices, and kaffir lime leaves are meant to infuse the broth and are generally left in the bowl rather than eaten.
Instructions
- Bring the chicken or vegetable broth to a boil in a medium pot over medium-high heat.
- Add the smashed lemongrass, torn kaffir lime leaves, sliced galangal or ginger, and smashed Thai bird’s eye chilies. Reduce the heat and let the mixture simmer gently for 5 to 7 minutes to infuse the broth.
- Stir in the mushrooms and cook for 2 minutes until they begin to soften.
- Add the shrimp (or tofu) and the Thai chili paste, stirring until the paste dissolves into the liquid.
- Cook for another 2 to 3 minutes until the shrimp are completely cooked through and pink.
- Turn off the heat entirely.
- Stir in the fish sauce and fresh lime juice, tasting and adjusting the seasoning to achieve your preferred balance of salty, sour, and spicy.
- Garnish with fresh cilantro and serve hot.
Description
This vibrant soup presents a translucent, ruby-tinted broth brimming with floating green herbs, red chili flecks, and tender pink shrimp. The aroma is intensely fragrant, dominated by the sharp, citrusy punch of lemongrass and the floral, pungent note of kaffir lime leaves. On the palate, it delivers an immediate zesty tartness followed by a warming, creeping heat from the bird’s eye chilies, rounded out by the deep, savory umami of fish sauce and chili paste.
