Instructions
Here’s the game plan—simple, fast, and full of flavor.
-
Prep the Prawns 🦐
Peel the prawns, keeping heads and shells for the broth. Devein the meat and set aside. -
Build the Broth 🔥
In a large pot, combine prawn heads/shells, chicken stock, lemongrass, galangal, kaffir lime leaves, chilies, and garlic.
Bring to a boil over high heat, then simmer covered on medium-low for 12 minutes.
Strain into a clean pot, ditch the solids, and keep broth on low heat. -
Add the Creamy Kick 🥥
Stir in coconut milk and Thai red chili paste until smooth. Simmer gently for 5 minutes—don’t let it boil hard. -
Load Up the Soup 💪
Add mushrooms, tomato, and onion. Simmer 3-4 minutes until veggies soften. -
Nail the Flavor ⚡
Add palm sugar, fish sauce, and lime juice. Taste and tweak: more sugar for sweetness, fish sauce for salt, or lime for zing. Aim for a bold sweet-sour-spicy balance. -
Add the Prawns🦐
Add the prawns and cook for 2 – 3 minutes.
-
Serve Like a Boss 🍴
Ladle into bowls, top with coriander, lime wedges, and chilies if you’re feeling spicy. Pair with jasmine rice for a full meal.
This Tom Kha Gai is a flavor bomb that’s stupidly easy to pull off. Enjoy!
