Step‑by‑Step Instructions for Japanese Onion Soup Recipe
Step 1: Sauté the Base
Heat a large pot over medium heat and add chopped onions, carrots, and celery. Sauté the vegetables for about 8-10 minutes, stirring occasionally, until the onions become soft and translucent. The sweet aroma will begin to fill your kitchen, setting the stage for your comforting Japanese Onion Soup.
Step 2: Add Aromatics
Once your vegetables are softened, add the minced garlic and freshly grated ginger to the pot. Cook for an additional minute, stirring constantly to release their flavors. You’ll know it’s ready when the garlic is fragrant, creating a lovely aromatic foundation for the soup.
Step 3: Incorporate Mushrooms
Introduce the sliced baby portobello and shiitake mushrooms to the pot, stirring them in gently. Sauté for another 5-7 minutes until the mushrooms release their liquid and become tender. Their earthy goodness will blend beautifully with the sweet onion and carrot base, enhancing the depth of flavors in your Japanese Onion Soup.
Step 4: Build the Broth
Pour in water along with the chicken stock and beef bouillon granules, stirring well to combine. Increase the heat and bring the mixture to a boil. As the soup reaches a gentle boil, the smells will intensify, signaling the next step in crafting your rich broth for the Japanese Onion Soup.
Step 5: Simmer to Perfection
Reduce the heat to low and let the soup simmer for 15-20 minutes, allowing all the flavors to meld together. Keep an eye on the consistency, as you want a light broth that is full of flavor. Stir occasionally and taste if any additional seasoning is needed.
Step 6: Final Seasoning and Serve
Once simmering is complete, add a splash of soy sauce for an extra umami kick. Stir gently and serve hot, garnished with freshly chopped chives for a touch of color and a mild onion flavor. Each bowl of your Japanese Onion Soup is now ready to warm your soul!

Japanese Onion Soup Recipe FAQs
How do I choose the right onions for my Japanese Onion Soup?
Absolutely! For the best flavor, I recommend using yellow or white onions. Look for onions that are firm and have a papery skin, free from dark spots or blemishes. Sweeter varieties will caramelize beautifully, enhancing the richness of your soup.
How long can I store leftover Japanese Onion Soup in the fridge?
You can store leftover soup in an airtight container for up to 3 days. Be sure to let it cool completely before sealing to maintain its fresh flavor. When you’re ready to eat, gently reheat it on the stove to bring back its warmth and depth.
Can I freeze my Japanese Onion Soup?
Very much so! To freeze, pour your cooled soup into portion-sized airtight containers or freezer bags—ideally, leaving about an inch of space at the top for expansion. It will keep well for up to 3 months. Just label them with the date, and when you’re ready to enjoy some, thaw the soup in the refrigerator overnight and reheat gently on the stove.
What if my soup tastes too salty?
If you find your soup is a tad salty, don’t worry! You can balance the flavors by adding more water or a splash of unsalted vegetable broth to dilute it. If it’s too late for that, try adding a small diced potato while simmering; it’ll absorb some saltiness. Just remember to remove the potato before serving!
Is this soup safe for my pet?
While the Japanese Onion Soup is delicious for humans, it’s crucial to know that onions are toxic to dogs and cats. If you’re sharing your meal with furry friends, it’s best to keep them away from this dish and opt for pet-safe snacks instead.
Are there any allergy considerations for this recipe?
Of course! This soup is generally well-tolerated, but be cautious if you have allergies to mushrooms or soy products, as they are key ingredients. You can easily omit mushrooms or use soy sauce alternatives to adjust for any sensitivities. Always check labels for hidden allergens if using store-bought products.
