What Is Tom Kha Gai?

Tom means boiled. Kha means galangal. Gai means chicken.

Straight up — the name tells you exactly what's in the pot.

Tom Kha Gai is a traditional Thai soup built on a coconut milk broth infused with galangal (a ginger cousin with a sharper, more citrusy bite), lemongrass, and kaffir lime leaves. It's fragrant, slightly tangy, mildly spicy, and deeply satisfying.

“This is the soup you make when you want to show up for yourself — no shortcuts on flavor, but no drama in the kitchen either.”

It's popular across Thailand and has earned a permanent spot in Thai restaurant menus worldwide — and for good reason.

How to Make Tom Kha Gai — Thai Coconut Chicken Soup

No fancy equipment. One pot. Do the work.

Step 1 — Build the Broth Base

Pour the chicken broth into a medium pot over medium heat.

Add the lemongrass, galangal, kaffir lime leaves, and chilies.

Let it simmer for 5–7 minutes. You're pulling flavor from those aromatics — don't rush it.

Step 2 — Add the Coconut Milk

Pour in the full-fat coconut milk. Stir gently.

Bring it back up to a gentle simmer — not a rolling boil. Boiling hard will break the coconut milk and you'll lose that silky texture.

Step 3 — Cook the Chicken

Add the sliced chicken directly into the broth.

Cook for 6–8 minutes until the chicken is cooked through and no longer pink. Thin slices cook fast — keep it moving.

Step 4 — Add Mushrooms

Drop in the mushrooms. Simmer for another 3–4 minutes until tender.

Step 5 — Season It Right

This is where you dial it in.

Add:

• Fish sauce — start with 2 tbsp, taste, adjust
• Lime juice — fresh squeezed, 2–3 tbsp
• Sugar — just 1 tsp to balance

Taste it. Consistent beats perfect — just keep adjusting until it feels right to you.

Step 6 — Serve

Ladle into bowls. Top with fresh cilantro, a squeeze of lime, and extra chili if you want heat.

Serve with jasmine rice or rice noodles on the side.

Pro Tips — Built Different Results

• 🥄 Don't eat the aromatics — lemongrass, galangal, and lime leaves are for flavor only. Fish them out before serving or just leave them in the bowl as visual cues.
• 🧊 Meal prep friendly — stores well in the fridge for 3 days. Reheat low and slow.
• 🌱 Make it vegetarian — swap chicken for tofu, use veggie broth, and sub soy sauce for fish sauce.
• 🛒 Can't find galangal? Fresh ginger works. Different flavor profile, but still worth the grind.
• 🥥 Use full-fat coconut milk — the creaminess is the whole point.
