What Is Japanese Onion Soup?

Japanese Onion Soup, also known as ‘Hibachi Soup,’ is a flavorful, light, clear broth often served as a starter in Japanese cuisine.

It combines the gentle sweetness of thinly sliced onions with the savory richness of chicken or vegetable broth, topped with finely chopped spring onions and mushrooms.

 It differs from its French counterpart by being less concentrated and without cheese. A traditional comfort food in Japan, this soup is loved for its simplicity, subtle flavors, and healthful properties, delivering a warm, satisfying experience with each spoonful.

Can You Vary The Recipe With Other Ingredients?

• Protein Tofu cubes or thinly sliced chicken can add a protein boost. For a seafood twist, try adding prawns or clams.
• Other Vegetables Feel free to include other veggies for added nutrition and flavor. Carrots, bok choy, or thinly sliced bell peppers can work well. You could add corn for a bit of sweetness.
• Mushrooms Swap out the traditional shiitake mushrooms for other varieties like cremini, portobello, or oyster mushrooms. Each type lends a unique flavor.
• Spices Add a slice or two of fresh jalapeno or a dash of chili oil for a hint of heat.
• Vegan/Vegetarian Use vegetable broth instead of chicken, and opt for a kombu and shiitake-based dashi for a fully vegan version.
• Garnish Besides green onions, consider garnishing with fresh herbs like cilantro or parsley. Sesame seeds or thinly sliced nori (seaweed) can add a different texture and flavor.

Variations, Add-Ons, And Toppings

Variations

• Add other vegetables, like thinly sliced carrots or baby bok choy, for a more substantial soup. 
• You can also experiment with different types of mushrooms beyond shiitake, such as cremini or maitake. 
• Include tofu, prawns, or thinly sliced chicken for a protein-packed version.

Add-Ons

• To add a unique twist, consider infusing the soup with flavors like ginger or lemongrass. 
• A splash of sake or mirin can also enhance the soup’s complexity. 
• A few slices of fresh jalapeno or a hint of chili oil can elevate the soup for those desiring a bit of heat.

Toppings

• While scallions are a classic topping, garnish the soup with fresh herbs like cilantro or parsley. 
• Seaweed strips, sesame seeds, or fried garlic chips could offer a crunchy contrast. 
• A dollop of miso paste or a drizzle of sesame oil just before serving can also enhance the soup’s flavor profile.

Can I Make The Soup In A Slow Cooker Or Instant Pot?

Slow Cooker

• Sauté the onions and mushrooms in a pan until lightly browned to bring out their flavors, then transfer them to the slow cooker.
• Add the broth and other ingredients, such as dashi or soy sauce, into the slow cooker.
• Set the slow cooker to low and let it simmer for 4-6 hours. This slow, gentle cooking will help to develop a deep flavor in the soup.
• Strain the soup before serving, garnish with scallions, and serve hot.

Instant Pot

• Use the sauté function to brown the onions and mushrooms.
• Add the broth and other ingredients to the Instant Pot, and secure the lid.
• Set the Instant Pot to pressure cook on high for about 15-20 minutes, sufficient time to develop the flavors.
• Once done, allow the pressure to release naturally before opening the lid.
• Strain the soup, garnish with scallions, and serve hot.

Can I Use Store-Bought Broth, Or Should I Make My Own?

• Store-Bought Broth: This is a convenient and time-saving option, ideal for whipping up a quick Japanese Onion Soup. However, choosing a high-quality, low-sodium broth is important to avoid an overly salty soup.
  Also, check the ingredient list for any unwanted additives or preservatives.
• Homemade Broth: Making your broth allows you to control the ingredients and the sodium level. You can also customize the flavors to your liking. Chicken, beef, or vegetable broths can all work well, each lending a distinct taste to your soup.
  Making your broth does take more time and effort, but many find the enhanced flavor worth it.

How To Serve?

• Serve Hot: Soup is best served hot. As soon as it’s ready, ladle it into bowls and serve. The flavors are more pronounced when it’s hot, and the warmth contributes to the comforting nature of the dish.
• Proper Dishware: Use deep bowls to serve the soup. Traditionally, Japanese Onion Soup is served in small, lidded bowls, but any deep soup bowl will work. Using Asian soup spoons can add an authentic touch and enhance the eating experience.
• Garnish: A sprinkle of fresh chives on top just before serving adds to the flavor and gives the soup a pop of color. You can also consider other garnishes like thinly sliced green onions, a sprinkle of sesame seeds, or a touch of seaweed for added visual appeal and taste.
• Accompaniments: The soup can be served as a starter before the main course or as part of a larger Japanese-inspired meal. Pair it with sushi, a simple salad, or a rice dish for a complete dinner.
• Freshness: The fresh ingredients like mushrooms and chives should have a vibrant color and texture. This ensures the soup looks its best and has the newest flavor.

Perfect Side Dishes

• Sushi Or Sashimi: Given the soup’s delicate nature, it pairs wonderfully with sushi or sashimi. These provide a nice contrast in flavors and textures.
• Japanese Salads: A simple cucumber salad with a soy-sesame dressing or a surimono (vinegar-based salad) would be a refreshing contrast to the warm soup.
• Yakitori Skewers: These grilled chicken skewers would add a smoky, savory element to your meal that complements the light, umami flavor of the soup.
• Gyoza Or Dumplings: Japanese-style dumplings, either pan-fried or steamed, are fantastic. You can choose from a variety of fillings to suit your preference.
• Steamed Rice Or Onigiri: A bowl of steamed jasmine rice or onigiri (rice balls) would work well with the soup, adding a filling and comforting element to the meal.

Storage And Make Ahead

• Storage: Store leftover soup in an airtight container in the refrigerator for up to 3 days.
• Freezing: You can freeze the soup in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight before reheating.
• Reheating: To reheat, gently warm the soup on the stovetop over low heat, stirring occasionally until heated through.
• Make Ahead: You can make the soup ahead of time and store it in the refrigerator for up to 2 days before serving. This allows the flavors to meld and develop, enhancing the taste of the soup.
• Flavor Enhancement: For even more flavor, consider making the soup a day ahead, as the flavors will intensify overnight.

What Can We Do With Leftovers?

• Rice Enhancer: Use the soup as a flavorful broth to cook rice or other grains. It’ll infuse them with a delicious umami flavor.
• Noodle Soup: Add some cooked ramen or soba noodles to the leftover soup for a quick noodle soup dish. You can also add excess protein or vegetables for a more substantial meal.
• Stir-Fry Sauce: Reduce the soup on the stove until it’s more concentrated, and use it as a sauce in a stir-fry.
• The Base for Other Soups: Use the leftover soup as a base for other soups. Add different vegetables, proteins, or grains to transform it into a whole new dish.
• Braising Liquid: Use the soup as a braising liquid for meats or vegetables. It will impart a wonderful flavor to the ingredients.

TIPS

• Enhance the flavor by caramelizing the onions before adding the broth. This step adds depth and richness to the soup.
• Use a combination of vegetable and chicken broth for a more complex flavor profile. The vegetable broth adds sweetness, while the chicken broth adds savory notes.
• Add a splash of mirin (sweet rice wine) and soy sauce for authentic Japanese flavor. These ingredients provide a balance of sweetness and saltiness.
• Include sliced shiitake mushrooms for an earthy flavor and chewy texture. They are a common ingredient in Japanese cuisine and complement the soup well.
• Garnish with chopped green onions and a sprinkle of toasted sesame seeds for added freshness and crunch. These toppings add a burst of flavor and visual appeal to the soup.
