What is Tom Kha Soup?

Tom kha kai, tom kha gai, or Thai coconut soup is a somewhat sweet, sour, and spicy soup that comes from Thailand. Tom Kha soup is misspelled and searched for as 'Tom Ka soup'. The soup has a refreshing coconut flavor. It is the perfect appetizer or main course, depending on how you serve it.

Why this is the best Tom Kha Soup Recipe ever?

Our tom kha soup is super easy to make. It is a one pot meal that takes less than 10 minutes to cook. 

It’s also super simple to prepare. You can even prepare the meal the night before for even easier dinner time prep on a busy night. 

Because you are adding tofu to the soup, it is also very filling. The tofu is packed with protein, which will help you feel fuller for longer.

When you make this soup, make sure to add some extra veggies like carrots or mushrooms to help sneak in some extra veggies for your family.

And if you follow a gluten free or vegan diet, this soup is perfect for you. Our soup is both gluten free and vegan, so you can easily serve it to anyone no matter their diet. 

Thai Coconut soup ingredients

Tom Kha Soup Recipe Ingredients

Once you are ready to make this soup, you’ll need these ingredients:

  • Coconut oil - This helps add some coconut flavor, so be sure to use it.
  • Shallots - They are a very mild, somewhat sweet tasting onion. In a pinch, sweet onions could work.
  • Galangal - Known as Thai ginger, this herb is very similar to ginger in flavor, so if you can’t find it, you can use more ginger.
  • Fresh herbs and spices - You’ll need ginger, lemongrass or paste, fresh Kaffir lime leaves, and Thai red chilies.
  • Salt 
  • Sugar
  • Sliced Mushrooms - You can use oyster, straw, or shitake. You can also add more veggies like carrots and bell peppers.
  • For the broth - You’ll need vegetable broth, lime juice, and coconut milk.
  • Crispy tofu - You can prepare your own or purchase from the store.
  • Garnish - You’ll want to have fresh cilantro and lime wedges to garnish the soup at the end.

Where can I find the ingredients?  

If you have any local Asian or Thai grocery stores, you should be able to find the Galangal, Thai chilies, and Kaffir lime leaves. 

But if you don’t have a local specialty shop, some larger or boutique shops may have them.

And if you can’t find them locally, you should be able to find them online at Amazon or other retailers.

How to make Tom Kha Soup in Instant Pot

Once you have all the ingredients, you need to follow these simple instructions for making this soup in the Instant Pot.

First, add all the ingredients to the Instant Pot’s inner pot, except for the crispy tofu, lime juice, coconut milk, and fresh cilantro.

Once all the ingredients are heated through, pour or ladle it into bowls and garnish with a lime wedge and fresh cilantro leaves.

Tips to make the best tom kha

When you make this soup, try these tips so it is as easy as can be:

  • Don’t add the tofu or coconut milk before pressure cooking. They will over cook under pressure.
  • Add carrots, mushrooms, baby corn, or others to fill out the soup.
  • You can add more or less chilies to make the soup spicier or milder.

Is Tom Kha soup gluten free?

This soup is both vegan and gluten free! That means it should fit into any one’s diet. 

Why did the coconut milk curdle?

Coconut milk can curdle if you place it under pressure. To avoid this, don’t add the coconut milk until after you have pressure cooked it.

How to Serve Tom Kha Gai

You can serve Thai coconut soup with tofu as an appetizer or as a main course if you want.

To fill it out a bit, we recommend adding a few veggies to the soup. You can also serve it with jasmine rice mixed in.

Or, you can serve it with our other Asian entrees like fried rice, hakka noodles, or massaman curry.
