Japanese Clear Onion Soup Recipe

The recipe card and video is at the bottom of the post, but don’t be too hasty! The post contains all the tips and tricks.

Japanese Clear Onion Soup

A while go we attended a birthday celebration at a Japanese Hibachi Steakhouse. It was my first time at one and I completely fell in love with a simple clear onion broth we were served as a starter. The name is Japanese Clear Onion soup!

I couldn’t believe how tasty that little bowl of brown broth was (haha)!

As with everything we eat, if we love it, we immediately know that we will eventually do our own recreation of it. This was no different.

After some research, planning, cooking and taste-testing, we finally perfected our very own Japanese Clear Onion Soup recipe.

Japanese Clear Onion Soup

What are clear onion soup ingredients?

With just 6 simple and easy vegetable ingredients, this is the perfect quick and easy vegetarian appetizer soup for your traditional Japanese (or Chinese) themed dinner party or if you’re just doing some fun homemade Benihana for the family.

If you’re like me, you’ll make it just because you love soup (and because this one is incredibly light and easy…and DELICIOUS).

So what ingredients goes into a Japanese Onion Soup recipe?

  1. Onion (Duh!)
  2. Carrot, Celery and Garlic (for depth of flavor)
  3. Mushrooms and Scallions (for garnish)
  4. Coconut Aminos (or Soy Sauce) and Sriracha (to boosting it to epic flavor proportions)

It is a very simple vegetable clear soup. So, it isn’t very substantial, but that’s exactly what makes it perfect as a starter. Or as a light meal with very low calories – perfect for weight loss.

So, now that you know what you need, now you need to know how to make this great clear broth mushroom soup.

How to make Japanese Clear Onion Soup for an Appetizer?

The best thing about this recipe, is that there’s hardly any hands on time, as with the majority of Living Chirpy recipes. What I’m trying to say is that you have no excuse to not impress your dinner guests with this cute little soup.

Even something as simple as “Clear Onion Soup” can seem special if you serve it as an appetizer in a pretty little bowl and an authentic little spoon.

  1. So, you start by frying the onions in a little bit of oil (preferably sesame oil for extra flavor) until they start to caramelize brown.
  2. Add the rest of the ingredients and let it simmer away for 30 minutes.
  3. Strain the vegetables from the water (don’t need to throw them away! I blend them and mix them in with my toddler’s food. Or I just snack on it myself)
  4. Garnish it with thinly sliced mushrooms and chopped scallions.
  5. Voilà!
  6. Japanese Clear Onion Soup is ready to be served.

  1. It didn’t taste right to me at all…I think I did too much celery….The recipe said two stalks which seemed extensive to me considering how little carrots there were. Is it actually supposed to be that? Like you mentioned in other comment replies you can’t know for sure because you weren’t there. I’m just a college student trying to learn how to make more stuff with very little cooking skills. Maybe not enough onions too. I added a lot of salt which seemed to help. It’s not horrible but isn’t what I was expecting compared to all the hibachi places i’ve been too. Especially Benihana’s! I will definitely try again though because I love this soup all year round…you can’t beat it!

  2. I was surprised also but realized that onions are sweet and carrots are sweet. Note that doesn’t mean they are bad just that when onions are sauteed their sweetness is released (making onion soup as delicious as it is) and when carrots are simmered their sugars are released. Both are healthy vegetables but I suspect that is where the carbs come from. I do not have the nutritional information on Siracha which may also contain some form of sugars. There are many brands of Siracha and I have seen cane sugar on at least one label. Brands may make a difference.
