Easy Tom Kha Soup (Vegetarian Thai Coconut Soup)

I’ll be honest, up until a few years ago, I had never before tried Tom Kha Soup (Thai coconut soup) in my life. I’d never even heard of it! At that point, the extent of my Asian cuisine experiences had been sushi, Chinese food, pad thai, and Mongolian beef at PF Changs (lol)…

A few years ago, I went to dinner with friends at a nearby Thai place. My friend ordered Tom Kha Soup and not knowing what it was, I tried it. OMG. IT WAS DELICIOUS. A little sour, yet spicy. Creamy because of the coconut milk. Flavorful from all the spices and veggies. YUM. I had wanted to remake this Tom Kha Soup ever since that day but I never got around to it.

Until today!

What is Tom Kha Soup?

Traditionally, Tom Kha Soup is a Thai soup made with coconut milk, lots of spices, lemongrass, galangal root, Thai fish sauce, and Thai chili paste. It’s as delicious and flavorful as you can imagine!

Here’s the thing… for this recipe, I wanted to keep things simple for you. My idea was to create a homemade version of Tom Kha Soup that you can make on a whim on a random weeknight. A deliciously easy version made with common ingredients found in your pantry or local grocery store.

Ingredients You’ll Need

Yellow onion + garlic – The base aromatics for this dish.
Mushrooms – I recommend using cremini mushrooms for this recipe since they have a mild flavor and won’t overpower the dish. Shitakes will also work!
Carrots – I like to thinly shred the carrots. It adds a unique earthly, slightly sweet, flavor to the soup.
Soy sauce – A common ingredient to use in place of fish sauce. I prefer to use low sodium soy sauce so the soup is not overly salty. You can also use coconut aminos in place of soy sauce.
Ginger – I like to use ground ginger instead of galangal since I always have it in my pantry.
Sugar – this helps balance all the savory flavors. You can also use coconut sugar if you prefer.
Cayenne pepper – I like to use this in place of chili paste since I always have it in my pantry. It adds some heat to the soup.
Lemon zest – Another easy-to-find ingredient to use in place of lemongrass which provides some fresh, brightness to the dish.
Full-fat coconut milk – I use canned coconut milk and I love how creamy it makes this soup when combined with the vegetable broth.
Cilantro – I like to add cilantro at the very end to give the soup an earthy flavor.
Green onions – this garnish provides a little bit of sweetness.
Lime juice – I love to add citrus to most soups but for this sweet-sour coconut soup, it’s just the perfect finishing touch.
