This refreshing Thai lemongrass soup is made with a light gingery broth, pan-fried tofu, cherry tomatoes and fresh cilantro.

Alissa’s note: I originally published this one back in December of 2014, and just updated the photos and recipe. That should explain why the paragraph below doesn’t quite make sense given the time of year. It also explains why the soup is actually perfect for August, which is why I decided to keep it. 🙂

After I made this the other day I realized I wasn’t sure of it’s appropriateness for this time of year. This might sound like a weird thing to say about soup, but it’s rather summery. Yeah, I know lots of people aren’t big on a hot bowl of spicy broth in the warmer months, but in this case I think the tomatoes, lime and cilantro make this a soup of the more refreshing variety.

Because I have a hard time hanging onto post material for more than a month without unleashing it on the world, I decided to let this one out anyway. Also, it does seem like something light and refreshing might be desirable in the near future.

Okay, I’m still pounding the bag of Christmas cookies my mom sent me home with last week, but those will soon be gone (I’m hoping they go off to work with my husband, and not into my belly, but time will tell). I’m betting by Friday we’ll all be ready for some healthiness.

This lemongrass soup is refreshing and healthy, but what’s great is that it’s also hot and comforting, and if you choose, spicy as well.

I will probably make this again in the summer just to test out my theory (<-- I did and it worked!!). Okay, I’ll probably make this again next week. It was really enjoyable, even on a rainy December evening, and it only took 25 minutes to throw together. So, I kind of have to make it again, you know, when I’m over Christmas cookies and all. I love it when my New Year’s resolutions pretty much take care of themselves like that.

  • Absolutely a big hit. Light and very flavorful. Husband and I both loved it. Added broiled chicken but tofu was probably enough. Keeping this recipe.
    Had grown lemongrass in my greenhouse- harvested it then searched recipes as I learn to use it. Your recipe definately a good find. Thankyou.
