Japanese Clear Soup

Pro tips

• Bloom the garlic and onion powder in the broth for 1–2 minutes after dissolving bouillon to deepen savory notes.
• Slice mushrooms thin (¼ inch or less) so they cook through in the hot broth without becoming rubbery.
• Add soy sauce and salt at the end and taste before serving—bouillon strength varies by brand, so adjust seasoning to your preference.
• Crispy fried onions should be added just before serving to maintain crunch; stir into individual bowls rather than the whole pot.

Substitutions

• Chicken bouillon → vegetable or dashi powder (maintains umami depth)
• White button mushrooms → cremini, shiitake, or enoki (changes earthiness; shiitake adds more soy-like flavor)
• Low-sodium soy sauce → tamari or coconut aminos (adjust saltiness; aminos add subtle sweetness)
• Baby carrots → carrot julienne or thin-sliced daikon radish (faster cooking; daikon adds peppery note)

Storage & make-ahead

Refrigerate broth in an airtight container up to 3 days. Reheat gently and add fresh mushrooms, scallions, and crispy onions before serving.

Can I use vegetable broth instead of water and chicken bouillon?

Yes. Substitute 4 cups vegetable broth for water and omit the bouillon powder for a vegetarian version with similar depth.

How do I make crispy fried onions at home?

Thinly slice onions, toss with cornstarch and salt, then shallow-fry in oil until golden and crispy (about 3–4 minutes). Drain on paper towels.

Can I prep this soup ahead?

Yes. Make the broth up to 2 days ahead and refrigerate. Slice mushrooms and scallions fresh, then add them when reheating to preserve texture.

What other vegetables work in this clear soup?

Snap peas, thinly sliced zucchini, spinach, or bok choy work well. Add delicate greens in the last minute to avoid overcooking.

Should the soup be hot or warm when served?

Serve piping hot, just like at hibachi restaurants. A rolling simmer ensures the broth carries full flavor to the table.
