Tom kha kai has become one of my favorite Thai soups. Lemongrass, lime and coconut milk are key flavors. I have made this several times– always with great results. What I like about this version is that you don’t need to find an exotic market to find the ingredients.This recipe is a simple, but effective, recreation of this Thai soup.
Are you ready?
You need 3 stalks of lemongrass. If you’ve never worked with this, it’s very easy to find in a grocery store nowadays. It looks like scallions on steroids– only they can be a challenge to cut. You need a really sharp knife, or you might want to grab an ax (well, not really). I, once bought, lemongrass in a tube (located in the produce section). It’s just not the same as real lemongrass. Remove the outside leaves, wash them and then…
…cut them into chunks, with a very sharp and sturdy knife.. I also chopped three shallots. Shallots are always in my fridge. I love them, because they are milder than red onion so they don’t overpower my sauces, or salad dressings. If you haven’t used shallots, much, try them. You’ll always want them on hand.
The rest of the ingredients are easy to find– fresh cilantro, coconut milk (I use the Lite version), chicken broth, red curry paste and fish sauce. Some of you might be wrinkling your nose at the thought of fish sauce. I did, too. However, give it a chance. Don’t sniff it! It’ll scare you. Honestly, the sauce is important and you cannot taste any fish. I wouldn’t lie to you!
You want to slice boneless, skinless chicken breasts into really thin strips. The trick is to freeze the chicken for about 15 minutes– this makes slicing it, on the bias (against the grain), so much easier. Don’t cut chunks! You want it nice and thin…you’ll see why in a few more steps.
Begin by tenderizing the lemongrass and shallots in a little vegetable oil. Season with 1 Tbsp of fish sauce and the chopped cilantro.
Once the flavors have infused, strain the soup and discard the veggies.
Add one more can of coconut milk, 1 Tablespoon of sugar and bring to a simmer. Add the sliced mushrooms and cook for 2-3 minutes. Now, add the thinly sliced chicken and cook until the pink is gone– stirring often– 2-3 minutes. This is why you don’t want big chunks of chicken!
Remove the chicken from the heat (as in turn off the stove!) and add 3 Tablespoons of fresh squeezed lime juice, the red curry paste. and 2 Tablespoons of fish sauce. You can serve the soup as an appetizer..
… to ladle soup over the rice, for a heartier meal. This soup comes really close to the authentic Tom kha kai soup from my favorite restaurant. We love it! It’s very simple to make, and the red curry paste gives a nice little kick to the soup.
TASTING NOTES: What a flavorful soup! If you love coconut, lime and lemongrass– this is the soup for you! Yes, you can easily substitute shrimp instead of chicken. I would even think you could use tofu as well, though I’m not sure if a vegetable stock would taste as authentic. This is a pretty economical dish to make. The Thai ingredients aren’t very costly and they last me for a while.

Debby, I can't thank you enough for posting Tom Gha Kai soup with such wonderful step by step photos. It is my all time favorite soup….probably even beating out Italian Tortellini! But I've been too timid to make it. I have nearly all the ingredients and NUMEROUS saved recipes and Thai cookbooks to refer to for this recipe. I trust your judgement and Cook's Illustrated (I have that issue, so I'll get it out too) and can't wait to make this soup! Blessings, Roz

What a wonderful recipe! Thai is one of my favorite cuisines and I tend to gravitate towards it at least 3 or 4 times a week! I've never made tom gha kai at home, I think it's time to try!
Kerstin says
Green curry is my favorite. Your soup looks delicious and could be served in a restaurant – yum! It's my hubby's favorite, so I should make it for him.

Your soup looks great, especially served over that white rice for a heartier meal. Pad thai to come? I can't wait!
