Tom Kha Gai is a surprisingly simple soup to make with all of the most delicious Thai flavors – a base of creamy coconut milk flavored with lime, savory fish sauce, and studded with bites of tender chicken. 

I had to go back and check twice to be sure that I didn’t already have a version of Tom Kha Gai on the blog somewhere. It’s one of my favorites – I can’t believe I overlooked it until now! It’s also incredibly easy to make once you gather the ingredients. With a base of creamy coconut milk, this soup is incredibly comforting. You can add spice if you’d like or skip it altogether. 

How is Tom Kha Gai Served?

Before we dive into the soup (figuratively speaking), a quick introduction to Thai-style meals. When we moved to Bangkok so many years ago, the first thing that made as feel at home was the sharing of meals. In Thailand most meals are served family style with a variety of dishes placed in the middle of the table. This includes soup which is ladled into small bowls and served alongside everything else. As a dinner at the table, you place a heaping spoonful of warm Jasmine rice on your plate and then serve yourself from the other dishes at the table. You hold a spoon in your right hand and a fork in your left and scoop some food and some rice onto the spoon before bringing it to your mouth. (Contrary to the message you get at many American Thai restaurants, chopsticks are reserved for noodle dishes.) Soup is often eaten in the same way. Scoop some rice into a spoon, dip it in the soup – eat it all together!

That said, Tom Kha Gai is perfectly delightful served as a meal all on its own. Rice on the side is great, but even that is optional.

Ingredient Notes

So, let’s talk ingredients! There are a few unique ones here. Check out my Guide To Thai Ingredients post for more info.

• Galangal – Galangal is a root that looks like ginger but has a very different, more floral, flavor. There’s no need to peel it first. Just wash it well and slice it into coins. 
• Shallots – Peel the shallot bulbs but leave them whole. 
• Lemongrass – Lemongrass comes in long stalks that can be a couple of feet long. Use only the lower few inches of the plant. Discard the tough outer stalks before using it. 
• Makrut Lime Leaves – There’s just no replacing the rich, exotic lime flavor and aroma that comes from makrut lime leaves. These leaves are available at any international / Asian grocery store and are often frozen (they store very well in the freezer). I also frequently find them at Whole Foods. When I find them I buy extra, rinse and dry them, and freeze them. If you don’t have them, be sure to squeeze a little extra lime juice into the soup for the lime flavor. 

Before you add these aromatic ingredients to the soup, you’ll want to break them up a bit so that they easily release their flavors into the soup.

Serving Aromatics in Tom Kha Gai

One of the unique things about the way this soup is served is that all of the aromatics are still intact. The beauty of serving the soup with the pieces of galangal, shallots, lemongrass, and makrut lime leaves in it is that the bowls of soup are incredibly aromatic. The slight downside is that you have to look out for them as you eat – those ingredients are far too tough to chew and eat, so just set them aside as you spoon up the other ingredients.
