Update July 2019: The recipe has been retested and improved.
I have to admit I was not sure how to call this recipe as it’s not a traditional Vietnamese or Thai recipe, it is inspired though. This soup consists of a flavorful lemongrass and tomato broth served with fried tofu, rice noodles, and a sweet, salty, and spicy fermented tofu sauce stirred in just before serving. Then it’s topped with a ton of fresh herbs.
This soup has a very different flavor than phở, it is lighter on spices and has a lemony, fresh taste.
It starts with the lemongrass that is finely chopped and sautéed until fragrant. Next comes the tomatoes that add a natural sweetness to the broth.
To bring freshness we have lemon leaves, some dried shiitake for umami, and a few chili pepper slices for spiciness. Lemon leaves can be found in Asian stores, usually in the frozen section.
While the broth is cooking, you prepare the fermented tofu sauce. It is stirred into the broth at the very last time, giving it a deeper, more savory flavor. Do not omit it!
The sauce consists of fermented tofu, also called bean curd, once again available in Asian stores. It is sold in a very salty brine, in a jar. To balance the saltiness of the tofu, we mix it with maple syrup, lime juice, sesame oil, and some chili paste.
Finally, we have the add-ins: crispy fried tofu, mushrooms, rice noodles, and a ton of fresh herbs. You can tweak the add-ins to your liking, adding roasted vegetables, tempeh, bean sprouts, etc.
If you like broths that are easy to make and have a deep, complex flavor, you definitely have to try this recipe! It is healthy, comforting, and so delicious!

* Fermented tofu can be found in Asian stores. It is sold in small jars, the tofu is stored in a very salty brine.
To fry tofu, pat it dry. Cut it into squares and lightly coat it with cornstarch. Heat about one cup of oil in a saucepan. Once hot, add the tofu and fry until it is golden brown, about 5 minutes. Transfer to a kitchen paper towel to remove excess oil.
