What is Thai Coconut Soup with Mushrooms?

Thai Coconut Soup with Mushrooms, often known as Tom Kha Het, is a fragrant, creamy Thai soup that combines the best of both worlds: rich coconut milk and bright, citrusy undertones from lemongrass and lime.

The mushrooms add a satisfying umami depth, soaking up all that ginger and red curry paste goodness. It’s the kind of dish that can make your kitchen smell like a Thai bistro in minutes—warm, spicy, and inviting. Think of it as your “rainy-day rescue” soup, but honestly, it’s just as crave-worthy on a sunny day when you want something comforting yet light.

Ingredients Needed to Make Thai Coconut Soup with Mushrooms

• ½ pound fresh mushrooms, sliced
• 1 tablespoon vegetable oil

Instructions to Make Thai Coconut Soup with Mushrooms

Making Thai Coconut Soup with Mushrooms is easier than it looks — and I’ll walk you through it step by step so you can enjoy a restaurant-quality soup right from your own kitchen. You’ll build layers of flavor, simmer everything to perfection, and finish with a burst of freshness that makes every spoonful irresistible.

Step 1: Build Your Flavor Base

Start by heating one tablespoon of vegetable oil in a large pot or Dutch oven over medium heat. This is your flavor foundation, so don’t rush it. Once the oil shimmers, toss in the grated fresh ginger, red curry paste, and minced lemongrass (if using). Stir constantly for about one minute — just until everything becomes fragrant. You’ll notice that heavenly aroma right away; that’s how you know your Thai Coconut Soup with Mushrooms is off to the right start.

Step 2: Add the Broth and Simmer Slowly

Now it’s time to build body into your soup. Gradually pour in the vegetable broth while stirring to lift up all those flavorful bits stuck to the bottom of the pot — they’re liquid gold for your soup base. Next, add the fish sauce, which gives that signature salty-sweet Thai flavor (don’t worry, it won’t taste fishy once everything blends together).

Bring the soup to a gentle simmer, then reduce the heat to low and let it cook for about 15 minutes. This step-by-step simmering allows the flavors to fully develop, creating a deep, rich base without needing long cooking times.

Step 3: Stir in the Coconut Milk and Mushrooms

Once the broth has simmered and smells irresistible, pour in the coconut milk and add your sliced mushrooms. Use full-fat coconut milk for that luscious, creamy texture we all crave in Thai soups. Stir everything gently to combine, then let the mixture cook over medium-low heat for another 5 minutes.
The mushrooms will soften and absorb the flavors beautifully, becoming little flavor sponges in your Thai Coconut Soup with Mushrooms. Keep an eye on it and avoid letting it boil — we want a gentle, velvety simmer, not a frothy mess.

Optional Twist: If you want a bit more texture, you can toss in some tofu cubes or rice noodles at this stage. For more ideas on customizing soups, check out my Creamy Chicken Parmesan Soup — it’s a great lesson in balancing creaminess and flavor.

Step 4: Add a Fresh Finish

Now for the finishing touches that make this Thai Coconut Soup with Mushrooms pop with freshness. Stir in the lime juice — start with two tablespoons and adjust to your liking. This step brightens everything and balances the richness of the coconut milk.

Taste your soup and see if it needs a touch more salt, curry paste, or lime. Everyone’s palate is different, so trust your taste buds. Once you’re happy with the flavor, ladle the soup into bowls and sprinkle chopped fresh cilantro on top for that restaurant-worthy finish.
Pro Tip: Serve it immediately with a side of jasmine rice to soak up that dreamy broth. For an extra cozy pairing, try it alongside Ginger Lime Chicken and Rice Soup for a light, fragrant dinner combo.

Step 5: Serve and Enjoy

And there you have it — your Thai Coconut Soup with Mushrooms is ready to enjoy! From start to finish, this step-by-step guide brings out the best of each ingredient: the warmth of ginger, the creaminess of coconut, the brightness of lime, and the savory depth of curry.

Key Tips for Making Thai Coconut Soup with Mushrooms

1. Don’t skip the ginger—it’s what gives the soup its signature warmth and slight kick.
2. If you can’t find lemongrass, a bit of lime zest makes a great substitute.

4. Taste as you go! Depending on your curry paste, heat levels can vary.
5. Make it vegan by swapping fish sauce for soy sauce or coconut aminos—it’s just as delicious.
6. Want to boost the protein? Add tofu cubes or edamame right before serving.
