Vegetarian Ramen (Vegetarian Tantanmen)

A delicious creamy, vegetarian friendly broth without all the cholesterol and without boiling for more than 12 hours? It’s entirely possible! This ramen recipe is so good and it offers the same delicious comfort as Tonkotsu broth or Paitan broth, both animal-based broths. This recipe was inspired by the vegetarian friendly Tantanmen from one of the best ramen places here, Mendokoro Ramenba.

The secret to delicious plant-based tantanmen is based on three components: The Tare (ramen seasoning), the broth, and the toppings. Since tantanmen is based on sesame paste, I made sure that I made my own sesame paste to include in the Tare or ramen seasoning to be able to control the strength of the flavor and the nuttiness coming from the sesame paste.

Then there are two major components for the broth – the actual clear broth, which was made by soaking some kelp and shitake mushrooms in water and bringing it almost to a boil. Then, every Japanese household secret to a quick creamy ramen broth: some good quality soy milk. I find that the best soy milk to achieve this is fresh soymilk of course, but also any asian brand of soy milk (like Soy Fresh). American soy milks have the tendency to neutralize the soy flavor from the milk and will be less effective for this one.

And of course we have the toppings! I used some Doubanjian (Chili Bean Paste) to make a flavorful “ground meat”, kind of like what we eat in Mapo/Mabo Tofu, but instead of pork, I ground the some rehydrated shiitake mushrooms in the food processor before sauteeing it with the chili bean paste. I also made Ajitama 1 day before making the ramen (you can do this 1-3 days earlier for a more jammy egg consistency). And finally, I braised Firm tofu in what normally is the liquid used to make Chashu, and then fried each side until lightly crispy before making beautiful delicate slices out of it. You can also add other toppings such as menma (bamboo shoots, which my sister and mom dislikes so I skipped it), some greens like bok choi, chopped green onions, and some thinly sliced wood-ear mushrooms.

Follow the recipe below to make this delicious 90% plant-based ramen! The ingredient list and the steps may seem long, but they take less time than Tonkotsu ramen and the results are so worth it! It would be perfect to make on rainy or cold day, especially on a weekend.
