Easy Thai Coconut Soup Recipe - Low Carb Keto Tom Kha Gai

What is tom kha gai?

Tom kha gai is a rich, creamy coconut-based soup that packs a nice sour punch with just the right level of spicy. Prepared with coconut milk, broth, and a mixture of herbs and spices, the base of this recipe is quite low in carbs already.

However, the typical Thai coconut soup served at a restaurant contains added sugar, loads more lime juice, including other additions that might not be the best choice for a ketogenic diet. Not to mention the side of rice that’s served alongside it.

Low Carb Thai Coconut Soup Recipe

There were a few changes I made to lower the carb count and eliminate ingredients with added sugar, gluten, or soy. I left out some of the usual add-ins: mushrooms, lemongrass, and of course, sugar. You can certainly enjoy mushrooms and lemongrass on a keto diet, but I always try to keep the ingredients to the bare minimum to capture the essence of a dish.

Not only does a minimalist cooking style make it easier to keep track of carbs, but it also makes the recipes easier to recreate at home. Any more than ten ingredients and my readers balk at the idea of making it.

In place of soy sauce, I used coconut aminos. Coconut aminos look and taste very similar to soy sauce, but it doesn’t contain soy or gluten. This replacement is the perfect option for those of us avoiding soy or gluten, but feel free to sub in regular soy sauce or liquid aminos if that fits in your diet.

I also chose to use Red Boat fish sauce for similar reasons; it’s the only gluten-free fish sauce I can find at my grocery store. I’m not sure if there are other gluten-free brands available, but I use Red Boat fish sauce likes it’s going out of style, so of course, it’s included in the recipe.

There are a variety of Thai garlic chili pastes to choose from, but I’ve only used the Huy Fong brand. It’s the same guys that make Sriracha, but no added sugar; I love it so much I should marry it.

I used a full-fat coconut milk, but if you prefer to reduce calories from fat, there are some really tasty brands of lite coconut milk that would work great in this dish. Tweak it however you need to fit with your macros!

        Delicious, I didn’t have Coconut Aminos so left out but will have to source some it sounds brilliant. I used a tbsp of Laksa paste to get the garlic, chilli, galangal and lemon grass flavour as didn’t have everything needed and it worked well, I also used a couple of chicken stock cubes as I didn’t have broth. Very easy and yummy, definitely will be a go to as can’t stop slurping it.

  • Would this taste okay using a vegetable stock and omitting chicken? While I live a ketogenic lifestyle, I teach cooking classes and some of those people are vegan. Any suggestions for this? I would definitely add in the mushrooms in this case.

  • Are the nutritional facts listed above accounting for the entire portion cooked? Or what is the serving size the nutritional facts apply to? šŸ™‚

    • The nutritional facts for each recipe on this site are per serving. The nutritional data is totaled, then divided by the number of servings indicated to give a per serving (or per unit, in some cases) nutrition label. For this recipe, the number of servings yielded from the entire recipe is 6, so 1/6th of the recipe is a single serving. Hope that helps!

    • You can use regular soy sauce or liquid aminos. Both are very low carb, even lower than the coconut aminos. I personally avoid gluten and soy, so I have switched over to coconut aminos for all things soy sauce flavored. Just a personal choice. Hope that helps!

    I really love this soup recipe!! If you cannot find Thai basil, regular will do fine. This soup is in regular rotation. My husband loved it as well. I’d make this whether I was doing keto or not! Sometimes I add lemongrass, if I have it. Wonderful. So tasty!

    I was going to ask this, but it seems someone already said regular basil is fine. My local store has dried Thai basil, would this work fine?

    I had a half of a store bought ooked chicken in the house and i always have coconut milk. I happily found your recipe and made this with cooked chicken and a ton of substitutes as i just got home from a two week vacation. Cupboards almost bare. And it was GREAT anyway ! Thank you thank you! Loved it 5 stars!

  • Very, very good! However, I cut the fish sauce in half to cut down on the sodium. It was still a bit salty for me. Maybe 1 T next time.

  • Where would I add in lemongrass and mushrooms…at the beginning or with the chicken….thank you…sounds delicious…love this soup

    WAY too much fish sauce. It ruined my entire batch of soup. I suggest starting with 1 T and working your way up. It just overpowers all the other flavors.

  • 5 stars
    This. Is. Phenomenal. I made it exactly like the recipe called for except I added 5 chicken breasts because they were small. I will be making this weekly!

  • Do you think you could add zoodles or some other veggie to this soup? (I saw a similar soup that used green curry and zoodles. I like the flavors in this one better but want to incorporate more veggies into everything.)

  • Amazing!! I can’t believe how easy this soup is to make to come out as delicious as it does. I cut the fish sauce to 1/8 of a cup due to the insanely high sodium content and added one kaffir lime leaf. I didn’t add the kaffir lime leaf last time but it took the soup to another level. Love this soup!!

  • Loved this recipe. Tasted just like the Coconut Soup that we love from our favorite Thai restaurant. I followed your recipe exactly as written and it was perfect except that used canned chicken breast for the meat. Love the heat! Now we can have this soup and not have to go out to eat to get it. Thanks!

  • I will be making this for sure. We have a new Thai restaurant nearby and I ate in the first time, but have been calling in to-go orders for the soup since. I buy 3 quarts at a time and try to make a quart stretch to 2 meals, but it’s really hard to do. I’m afraid I’m totally addicted to it now. It is, hands down, the most delicious soup I’ve EVER had in my life. I just close my eyes and drink it in. It transports me to another place. That’s sad isn’t it? I’m going to add a side of steamed broccoli or cauliflower, a piece of meat and/or a big salad. I know I need to have more than just soup all day, because I fast, (other than fat coffee for breakfast), and eat one meal at night. I know that this is TMI!

    Just made this for dinner tonight. It was stupid how easy it was to literally throw together, hardest part was probably slicing the chicken. Which I definitely recommend using thighs instead of breasts to add more fat and flavor. I also added a lemongrass stalk that I smashed and just let steep in the soup because I just really like lemongrass. Definitely going to make it again!
