Thai Spicy Shrimp Soup: Tom Yum Goong
Thai Spicy Shrimp Soup: Tom Yum Goong is the kind of bowl that grabs your senses immediately: fragrant lemongrass, tart lime, a chorus of chilies, and plump prawns swimming in a bright, savory broth. It’s the soup you crave on a cool evening or whenever you want a quick, vibrant escape to spicy, citrusy comfort. Below, I’ll walk you through an authentic-feeling version using 5 prawns (ideally fresh), fragrant aromatics, and an optional creamy twist that still keeps everything bold and balanced.
Why this recipe works
This recipe leans on a handful of powerful ingredients to create deep, layered flavor without fuss. Fresh prawns provide a sweet briny backbone. Lemongrass and kaffir lime leaves deliver the citrusy lift that makes each spoonful bright. Galangal adds warmth and a peppery undernote. Straw mushrooms soak up the broth and give pleasing texture. Nam Prik Pao (Thai chili paste) rounds everything out with smoky, sweet heat. Finally, lime, fish sauce, and a pinch of sugar tune the balance between sour, salty, and sweet.
The ingredient list and method below are written to be clear and approachable. Follow the step-by-step directions, and you’ll have a restaurant-quality bowl in about 20 minutes.
Ingredients
- 5 prawns (ideally fresh)
- 2 stalks lemongrass
- 6 Kaffir lime leaves torn
- ½ inch knob of galangal thinly sliced
- 100 g straw mushrooms halved
- ½ box evaporated milk (or fresh milk, optional for creamy version)
- 2-3 tbsp Thai chili paste (Nam Prik Pao)
- 1 handful bird’s eye chilies slightly crushed
- 6 pieces red Thai chilies sliced or left whole (for extra heat)
- 2 limes
- Salt (to taste, optional)
- Fish sauce (to taste)
- Sugar (or to taste)
- Fresh sawtooth coriander or cilantro (to garnish)
Prep notes and tips
- Use fresh prawns for the best texture and flavor. Rinse them briefly and pat dry. You may peel and devein them if you prefer; leaving tails on is fine for presentation.
- Smash the lemongrass stalks lightly with the back of a knife before slicing; this releases more aroma into the broth.
- Tear the Kaffir lime leaves rather than finely chopping them; torn pieces release oils and are easy to fish out before serving if desired.
- Galangal is different from ginger: it’s firmer and spicier. Slice thinly so it imparts flavor without making the soup gritty.
- Straw mushrooms cook quickly; halving them helps them absorb broth flavors.
- If you prefer a creamy finish, add ½ box evaporated milk or fresh milk in the final minute of cooking. The milk mellows heat and adds body.
- Nam Prik Pao varies in intensity and sweetness by brand; taste as you go and start with 2 tablespoons if you’re unsure.
- Adjust chilies to your heat tolerance: the bird’s eye chilies are potent; use whole for milder heat and sliced for immediate spice.
Step-by-step directions
Follow these steps in order. The rewritten directions below keep the same sequence as the ingredient list and present each action clearly and precisely.
- Prepare the aromatics: Trim and lightly smash the 2 stalks lemongrass, then slice them into 1–2 inch pieces. Tear the 6 Kaffir lime leaves into large pieces so their oils will release into the broth. Thinly slice the ½ inch knob of galangal.
- Heat the broth base: Place a medium pot over medium heat and add about 4 cups of water (or light stock if you prefer). Bring the water to a gentle simmer.
- Infuse flavors: Add the smashed and sliced lemongrass, torn Kaffir lime leaves, and sliced galangal to the simmering water. Let them simmer for 5–7 minutes so the broth becomes aromatic. Keep the heat at a gentle simmer to avoid over-reducing the liquid.
- Add mushrooms and initial spice: Add the 100 g straw mushrooms (halved) to the pot. Stir them into the broth and let cook for 2–3 minutes so they begin to soften and take on flavor.
- Incorporate the chili paste: Stir in 2–3 tbsp Thai chili paste (Nam Prik Pao). Whisk it into the broth so it melts and disperses evenly. Simmer for 1–2 minutes to meld the flavors.
- Add chilies for heat: Add 1 handful bird’s eye chilies slightly crushed to the pot. If you want extra visual heat and a sharper bite, also add the 6 pieces red Thai chilies, either sliced or left whole as you prefer. Let the broth simmer for another 2 minutes so the chilies infuse their heat.
- Cook the prawns: Add the 5 prawns (ideally fresh) to the simmering soup. Gently poach them for 2–4 minutes, depending on size, until they turn pink and curl. Do not overcook; prawns become rubbery if left in hot liquid too long.
- Optional creamy version: If you want a creamier soup, lower the heat slightly and stir in ½ box evaporated milk (or fresh milk). Warm just until the milk is heated through—do not boil vigorously after adding milk to prevent curdling. Taste and adjust seasoning.
- Finish with brighteners and season: Squeeze in the juice of the 2 limes, adjusting to your preferred tartness. Add fish sauce to taste for umami and saltiness—start with a tablespoon, then tweak. Balance acidity and salt with a little sugar if needed. Taste the broth and add salt sparingly if more seasoning is required.
- Final simmer and check: Let the soup sit off the heat for a minute so flavors round out. If you used milk, keep the heat low and avoid boiling. Check the seasoning one last time and adjust lime, fish sauce, or sugar until the sour-salty-sweet balance is pleasing to you.
- Serve and garnish: Ladle the soup into bowls. Scatter fresh sawtooth coriander or cilantro leaves over the top. If you left whole chilies in the pot and want to keep the heat gentle for guests, fish them out before serving; otherwise leave them in for a dramatic presentation.
Serving suggestions
Serve this soup piping hot with steamed jasmine rice or a small bowl of rice on the side to temper the heat. A crisp cucumber salad or lightly dressed greens make a cooling counterpoint. For a heartier meal, add glass noodles or more mushrooms.
Flavor adjustments and troubleshooting
- Too spicy: Add a splash more milk, a teaspoon of sugar, or an extra squeeze of lime to mellow heat.
- Too sour: Add a touch more fish sauce or a pinch of sugar to round the tartness.
- Too salty: Add more water or a splash of milk to dilute the saltiness, then rebalance with lime and sugar.
- Broth tastes flat: Make sure the lemongrass, galangal, and kaffir lime leaves had time to infuse. Add a little more Nam Prik Pao for depth or a splash more fish sauce for umami.
Notes on ingredients and swaps
- Prawns: Fresh is best for texture and flavor. If fresh isn’t available, use thawed frozen prawns. Keep the stated amount of 5 prawns.
- Nam Prik Pao: If you can’t find this paste, a combination of mild chili paste and a touch of roasted shallot or sweet chili paste can work in a pinch, but the trademark smoky-sweet depth won’t be identical.
- Evaporated milk: This adds creaminess without overpowering the original profile. Fresh milk can be substituted 1:1, but use light simmering to avoid curdling. If you prefer no dairy, skip it entirely for the traditional clear version.
- Bird’s eye and red Thai chilies: These are primary sources of heat and visual appeal. Adjust quantities or remove seeds if you want a gentler spice.
- Fish sauce: This is the main source of savory depth. Use a robust, fish-forward sauce and add gradually—start small and taste.
Make-ahead and storage
You can prepare the broth base (lemongrass, galangal, lime leaves, and mushrooms) up to 24 hours in advance and refrigerate. Add the prawns and finish the soup just before serving to keep the prawns tender. Leftover soup keeps in the refrigerator for up to 2 days. Reheat gently on the stove—if the soup contains milk, warm slowly and avoid boiling.
