Complete the dish by adding in the fried onion and sliced mushrooms for extra flavor and texture. Pair this dish alongside a delicious serving of tamagoyaki (Japanese rolled omelette). 

Tips on Making Copycat Benihana Onion Soup

This Japanese soup goes by a lot of different names. It’s sometimes called Japanese clear soup, Japanese mushroom soup, or even clear mushroom soup. This is because the traditional garnishing of this soup is with mushrooms and green onions. However, the Benihana Hibachi soup version adds in fried onions as well. You can also try mixing in other ingredients so it’s extra flavorful. Try out some of our recipe variations down below:

  • Use other kinds of mushrooms. Aside from the white beech mushrooms, you can also use white button mushrooms or baby bella mushrooms (cremini) which is the best choice of mushrooms for this Japanese steakhouse dish. This type of mushroom is slightly bigger than white beech mushrooms, and has a mild to deep flavor. It’s perfect for giving your soup an additional umami mushroom broth flavor. 
  • Try adding in beef broth. You can also substitute the chicken broth with beef, or combine both flavors! Try mixing in 3 cups of chicken broth, 2 cups of beef broth, and 1 cup of water. Or, add in ½ tablespoon of beef bouillon granules and a pinch of ginger powder to further enhance the broth’s flavor.
  • Add soy sauce for a richer broth flavor. If you want a bit of a salty, savory, and umami taste, then add about ½ tablespoon of soy sauce in the boiling broth. Soy sauce is an essential ingredient and a popular seasoning in Japanese cooking, and in other Asian dishes. This will make your Benihana inspired Japanese onion soup even more appetizing with its subtle hints of salty, savory, and umami flavors. 
  • Mix in garlic. Another way to make this Benihana onion soup even tastier is mixing in ⅓ tablespoon of minced garlic for that unique garlic flavor in your broth. Add this when you’re boiling and simmering all of the ingredients together so that the garlicky flavor seeps into the delicious broth.

Frequently Asked Questions

Is Japanese clear soup healthy?

Yes, it is light and low in calories, but not extremely nutritious so we recommend eating this dish in moderation. Since this soup is full of vegetables, it makes for a low-fat and high-fiber dish which is a good healthy soup option. You can also make this Benihana onion soup vegetarian friendly by switching out the chicken or beef broth with vegetable broth. Although, this will make your clear soup Japanese dish slightly less savory. But you can always add in seasonings like a bit of soy sauce, salt and pepper, fresh ginger, peanut oil, or even sriracha for some added kick.

Is Japanese clear soup the same as miso soup?

No, they are not the same. Both soups use different main ingredients which affect the color and appearance of the broth or soup. For instance, the key ingredient in making the miso soup broth is the miso paste made from fermented soybeans. This gives the miso soup a cloudy or almost opaque appearance. On the other hand, a Japanese clear onion soup has a clear soup base. So, what is clear soup? It’s achieved by boiling and simmering together meat broth and vegetables, then straining and removing the solid ingredients. What is left is a clear liquid soup with mushrooms and onion garnishes.

Can I freeze this Hibachi soup?

Yes, you can! This Japanese soup freezes well; just make sure that you store it in an airtight container so it lasts for up to 3 months. When ready to consume again, thaw the soup first and then reheat using the microwave or stovetop. For the microwave, place on a microwave safe container and heat for 1 to 2 minutes on medium heat. If using the stovetop, place on a small pot over low-medium heat. Stir gently to warm it up and heat for about 5 minutes until hot. Feel free to top with more freshly sliced mushrooms or green onions.
