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!
