Pin it The first time I tasted Tom Yum was at a tiny Thai restaurant in Seattle where the chef's mother came out of the kitchen to teach me how to eat it properly. She told me the secret is in the aromatics, not just the heat. That bowl changed how I understood soup forever, it's not just a starter but a complete experience that wakes up every sense.
Last winter my sister came over complaining she couldn't shake a cold. I made this soup with extra chilies and lime, and she left saying she could actually breathe again for the first time in a week. Now whenever anyone mentions feeling under the weather, this is what I put on.
Ingredients
- 4 cups chicken or vegetable stock: The base carries all those gorgeous aromatics, homemade stock adds depth but quality store-bought works perfectly
- 2 stalks fresh lemongrass, trimmed and smashed: Smashing releases the citrusy oils that make Tom Yum sing, dont skip this step
- 4 kaffir lime leaves, torn: Tearing them releases more essential oils than leaving them whole, they're worth seeking out at Asian markets
- 3 slices fresh galangal: This piney ginger relative is non-negotiable for authentic flavor, regular ginger works in a pinch but galangal is the real deal
- 2 Thai birds eye chilies, sliced: Start with one if you're heat-sensitive, you can always add more but you cant take it back
- 250 g large shrimp, peeled and deveined: Shrimp cook fast and stay tender, look for ones with translucent shells and no ammonia smell
- 150 g white mushrooms, sliced: They absorb that incredible broth while adding meaty texture and earthy balance
- 2 medium tomatoes, cut into wedges: The acidity plays beautifully with the lime, they soften just enough to release juices into the soup
- 1 small onion, sliced: Adds sweetness that rounds out the sharp flavors, red onion works too for milder notes
- 2 tablespoons fish sauce: The umami foundation that makes everything taste more like itself, skip only if strictly vegetarian
- 1 tablespoon lime juice: Brightens and lifts all the heavy flavors, have extra limes ready at the table
- 1 teaspoon sugar: Just enough to balance the sour and heat without making it sweet, trust this ingredient
- 1 teaspoon chili paste (nam prik pao): Optional but creates that restaurant-quality depth and slight smokiness
Instructions
- Build the aromatic broth:
- Bring the stock to a gentle simmer, then add lemongrass, kaffir lime leaves, galangal, and chilies. Let it steep for 5-7 minutes so the broth becomes infused with those essential oils.
- Add the vegetables:
- Drop in mushrooms, tomatoes, and onion. Cook for 3-4 minutes until they start to soften but still have some bite.
- Cook the shrimp perfectly:
- Add shrimp and cook just 2-3 minutes until they turn pink and opaque. Overcooking makes them rubbery, so watch closely.
- Balance the flavors:
- Stir in fish sauce, lime juice, sugar, and chili paste. Taste and adjust, adding more lime for brightness or fish sauce for depth.
- Finish and serve:
- Remove from heat and fish out the lemongrass and galangal if you prefer. Ladle into bowls and top with fresh garnishes.
Pin it This soup became my go-to dinner party dish because it looks impressive but requires almost no active cooking time. Guests always ask for the recipe, and I love watching their faces when that first spicy spoon hits.
Making It Vegetarian
Swap shrimp for firm tofu cubes and use soy sauce or a vegetarian fish sauce alternative instead of regular fish sauce. The rest of the aromatics stay exactly the same, and you still get that incredible hot and sour balance that makes Tom Yum so addictive.
Getting The Heat Right
Thai bird's eye chilies pack serious punch. Start with one sliced chili, then add the second only after tasting the finished soup. Remember that the heat mellows slightly as it sits, so what burns at first might be perfect five minutes later.
Serving Suggestions
While this soup stands alone beautifully, a bowl of steaming jasmine rice on the side makes it a full meal. The rice tempers the heat and soaks up that incredible broth. Some nights I skip the rice and serve it as a light starter, letting those bold flavors shine without anything to compete.
- Have extra fish sauce and lime at the table so everyone can adjust their bowl
- A cold beer or dry Riesling cuts through the spice beautifully
- Leftovers keep for two days but the texture is best fresh
Pin it Every bowl of this soup transports me back to that little Seattle restaurant. Hope it becomes your comfort too.
