Tom Kha Gai (aka Thai Chicken Coconut Soup) is one of my favorite soups and these Keto Tom Kha Noodle Bowls do not disappoint!
Tangy, creamy, and just a touch spicy this soup is packed with fragrant ingredients like lemongrass, fresh ginger, and kaffir lime leaves. If you can’t find lime leaves, feel free to sub in a few tablespoons of fresh lime juice and maybe a pinch of lime zest. If you also can’t find wild Asian mushrooms, you can even use button or cremini mushrooms.
Traditional Tom Kha soup uses galangal but we simply used ginger root because it's more common and easy to find in almost any grocery store. If you want to make your Tom Kha authentic and don't mind the extra trip to an Asian market, swap the ginger for galangal root.
This tasty Thai soup recipe makes four generous servings that can be served as mains, or up to eight smaller servings that can be served as appetizers. It can be made on the stove top or even in an Instant Pot if you've got one.
Finally, don’t skip the toppings. A crunch of a serrano and a drizzle of chili oil give this spicy Thai soup a nice kick!
