Japanese Clear Onion Soup specifically is a very light, clear soup made from a meat or vegetable broth with a strong onion flavor. It is simmered for 30 minutes to unlock the flavors and then strained to achieve a clear and flavorful onion soup.

Authentic Japanese Clear Soup is generally garnished with fresh sliced scallions and thinly sliced mushrooms.

It is a very common and very popular soup served at Japanese Restaurants, and is a staple on any Hibachi Steakhouse menu.

Ingredients to Make Japanese Clear Onion Soup:

  • Vegetable Broth – can use chicken or beef broth as well
  • Onion
  • Carrot, Celery, Garlic and Ginger
  • Mushrooms and Scallions
  • Toasted Sesame Oil
  • Coconut Aminos, Soy Sauce or Sriracha – optional for flavor

How to Make Japanese Clear Onion Soup:

  1. Roughly chop the onions, carrots and celery (no need to peel the carrots).
  2. Slice the ginger and garlic into rounds in order to expose more surface area and unleash the most of its flavor.
  3. I like to start off by slightly caramelizing the onion in a bit of regular oil in order to unlock their full deliciousness. About 10 minutes.
  4. Then, I add the carrots, celery, garlic, ginger, and toasted sesame oil.
  5. Pour in the chicken broth. Bring the soup to a boil, and then lower the temperature and allow to simmer for at least 30 minutes.
  6. Strain all the solid particles out of the soup. (It’s up to you what you’d like to do with all the solids. I don’t like waste so I keep it and throw it in another meal. A little extra fiber never hurt anybody)
  7. Garnish with fresh sliced scallions, very thinly sliced button mushrooms and serve it up! I personally enjoy a splash of soy sauce (or coconut aminos if you’re on the Whole 30 or Paleo diet), as well as a little squirt of sriracha.

Nutrition Facts for Japanese Clear Onion Soup:

Here’s an approximate estimate of the nutrition facts per serving. Please note that these values are approximate and can vary based on factors such as the exact quantities used, specific brands of ingredients, and cooking methods:

What does clear soup mean?

A clear soup is as the name suggests, a richly flavored clear liquid broth that can be made from any meats, vegetables, herbs, spices and flavorings. It has to be strained at the end, because a strict definition of “clear soup” or ”clear broth” means that no solid parts can be present in the soup.

Is this popular hibachi soup healthy?

As you can see, it is a very simple clear soup recipe – as is most clear soup variations. This means that it is not extremely nutritionally substantial and is very low in calories, but that’s exactly what makes it perfect as a light starter.

What else can I add to this soup?

Some people do enjoy adding shredded chicken and have it for a light meal that is very low calories. This is quite delicious and perfect for weight loss, but then not exactly a Japanese Clear Onion Soup anymore.
