Soups & Stews
This Benihana clear soup recipe delivers the restaurant's signature crispy celery crowns floating in a silky tomato velouté, a dish that balances umami depth with delicate textures.
The secret lies in layering flavors through precise simmering techniques—dashi forms the aromatic base, while kombu and bonito flakes infuse the broth with oceanic richness. For pescatarian-friendly appeal, shrimp or scallops add a tender protein element that harmonizes perfectly with the broth's complexity.
The recipe begins with a 30-minute simmer of kombu and bonito flakes to create a fragrant dashi foundation, then builds to a velouté using tomato paste and vegetable stock. Celery is blanched and flash-fried to achieve that signature crispy texture, while mushrooms or herbs can be added for modern twists.
The result is a soup that's both restaurant-quality and approachable for home cooks.
What sets this recipe apart is the attention to traditional techniques—proper simmering times develop depth, while the celery crowns require careful timing to maintain their crispiness. The presentation elevates the dish further, with each bowl featuring a delicate arrangement of celery and protein.
This is a soup that feels special yet remains simple enough for weeknight preparation.
The versatility of this recipe extends beyond the classic version. Swap in seasonal vegetables or experiment with different proteins like crab or tofu while maintaining the core technique.

The kombu and bonito flakes are the foundation of this soup's umami depth. Kombu should be high-quality—look for thick sheets at specialty stores like Matsumoto Shokai or Asian markets. Bonito flakes lose potency quickly, so store them in the freezer. For the celery crowns, thick, crisp stalks are essential—they should snap when bent. If you can't find them fresh, Trader Joe's often carries pre-cut celery crowns in their frozen section. The shrimp should be fresh or frozen, with a sweet aroma and translucent appearance when thawed.
No kombu? Dashi powder works in a pinch, though it lacks the depth of homemade. Out of bonito flakes? Dried sardines or anchovies can substitute, but remove them after simmering. For the celery crowns, zucchini or fennel can replace half the celery if needed. The tomato paste can be swapped for sun-dried tomatoes (soaked and chopped), though the color will differ. If using dried shiitake mushrooms, rehydrate them in hot water for 20 minutes—the soaking liquid adds another layer of umami to the broth. The shallots and garlic should be minced finely for a smooth velouté.
The dashi should be strained through a fine-mesh sieve to remove any kombu fibers. Store the broth in the fridge for up to 5 days or freeze in ice cube trays for 3 months. Celery crowns are best fried fresh, but you can reheat them in a dry pan for 20 seconds to restore crispness. The shrimp can be cooked ahead and stored in the fridge for 2 days—just reheat gently in the broth before serving. For presentation, arrange the celery crowns and shrimp artfully in each bowl, finishing with a drizzle of olive oil and parsley. The dish tastes even better the next day as flavors meld.

Step-by-step instructions for Benihana clear soup
Master the technique behind Benihana's signature crispy celery crowns and velvety tomato broth.
Prepare the Umami Base with Kombu and Bonito
Place the 1 sheet dried kombu in a clean pot and cover it with the 4 cups vegetable stock. Bring to a gentle simmer over medium-low heat for 15 minutes—this infuses the stock with deep oceanic notes. Remove the kombu immediately after simmering, as it will become bitter if left too long.
In a separate bowl, toast the 0.5 cup bonito flakes in a dry skillet over medium heat for 1-2 minutes until they turn a rich golden brown. This develops their nutty aroma. Strain the flakes through a fine-mesh sieve into the kombu-infused stock, reserving the liquid. The flakes will dissolve completely, creating a complex umami foundation.
Build the Tomato Velouté
In the same pot, whisk in the 2 tbsp tomato paste and cook for 3 minutes over medium heat, stirring constantly until it darkens slightly. This caramelization deepens the flavor profile. Add the 2 minced shallots, 3 minced garlic cloves, and 4 sliced white mushrooms, cooking for another 5 minutes until the vegetables soften and release their moisture.
Pour in the reserved kombu-bonito stock and bring to a gentle simmer. Reduce heat to low and let it cook uncovered for 20 minutes, allowing the flavors to meld. The soup should reduce slightly, creating a concentrated, silky texture. Season with the 1 tsp kosher salt and taste—adjust if needed for balance.
Create the Celery Crowns
Cut the 4 whole celery stalks into 1-inch thick rounds, keeping the core intact. In a separate skillet, melt the 2 tbsp unsalted butter over medium heat until foaming. Dredge each celery round in the 1 tbsp all-purpose flour, shaking off excess, then fry for 2-3 minutes per side until deep golden brown and crispy.
Real talk: Don't rush this step. The celery should develop a crispy, almost caramelized exterior while remaining tender inside. If it browns too quickly, reduce the heat slightly. Transfer the fried celery to a wire rack to drain excess butter.
Finish with Shrimp and Garnish
Add the 12 peeled shrimp to the simmering soup and cook for 2-3 minutes until they turn opaque and curl slightly. The shrimp should be just cooked through—overcooking will make them rubbery. Remove them with a slotted spoon and set aside.
Stir in the 0.25 cup extra-virgin olive oil and 0.25 cup chopped fresh parsley to finish the soup. The oil adds richness while the parsley brightens the dish. If using the 2 rehydrated dried shiitake mushrooms, slice them and add now for added earthiness.
Plate for Maximum Impact
Divide the tomato velouté among bowls, arranging 3 crispy celery crowns in each. Place 3 shrimp on top of the celery, fanning them slightly for visual appeal. The contrast of the crispy celery against the silky broth creates the signature Benihana experience.
Serve immediately while the celery remains crisp and the shrimp stays warm. The soup should be hot enough to steam the celery slightly upon the first bite—this is the moment that matters. Pair with steamed rice to soak up every last drop of that velvety broth.
Pro Tips For Making Benihana Clear Soup
- SOAK KOMBU FIRST: Skip the dry-roasting step and soak the kombu in cold water for 10 minutes before adding to the stock—it softens the texture and prevents that bitter aftertaste I used to get when I just tossed it in dry.
- TOAST BONITO LOW: Heat the bonito flakes over low heat for 20 seconds max, stirring constantly. Burn them once, and you’ll taste it in every sip—like eating fishy ashes.
- SHRED SHALLOTS FINE: Pulse shallots in a food processor until they’re almost paste-like, not just chopped. The soup will have a smoother, richer base, and you’ll avoid that chewy texture that ruins the clarity.
- STIR TOMATO PASTE: Whisk the tomato paste into the stock before adding the kombu, and keep stirring for 30 seconds. This prevents clumping and gives that deep, umami-rich color Benihana’s version has.
Make-ahead tips for this dish
Broth Prep Ahead
Make the kombu-bonito broth up to 3 days in advance—it only gets better as flavors meld. Store it in an airtight container in the fridge. When ready to use, simply reheat over low heat for 10 minutes before adding your tomato velouté ingredients.
I always double the batch since it works perfectly in other dishes like miso soup or ramen. 💫
Celery Crown Prep
Celery crowns are best fried fresh, but you can blanch them ahead to save time. Simmer the celery rounds in boiling water for 2 minutes, then shock in ice water.
Store in the fridge for up to 2 days—when ready to serve, pan-fry them in butter for just 1-2 minutes per side until crispy again. This shortcut keeps their texture intact. ⏰
Protein Prep
Cook the shrimp in advance and store them in the fridge for up to 2 days. Keep them in a single layer on a plate to prevent sticking. When reheating, gently warm them in the broth for 30 seconds—this ensures they stay tender and plump.
For extra flavor, toss them with a pinch of kosher salt and 1 tsp olive oil before storing. 🦐
Complete Soup Assembly
Assemble the soup 1 hour before serving by combining the reheated broth, tomato velouté, and any prepped ingredients. Keep it warm in a slow cooker on low heat or a double boiler—this maintains the silky texture without overcooking.
The celery crowns and shrimp can be added just before serving to keep their crispness. 🔥
Storage Tips
Store the complete soup (without celery crowns) in the fridge for up to 3 days or freeze for 1 month. When reheating, warm it gently on the stove over low heat, stirring occasionally.
For frozen soup, thaw it in the fridge overnight and reheat slowly. Always add the celery crowns fresh to maintain their signature crunch. ❄️
Nutrition facts
Frequently asked questions
Can I make this soup vegetarian or vegan?
Skip the shrimp and use 12 oz king oyster mushrooms or tofu cubes instead. For umami depth, add 1 tbsp soy sauce or 1 tsp miso paste to the broth. The celery crowns and tomato velouté remain the same—just ensure your butter is vegan if needed.
Why does my celery turn soggy instead of crispy?
Overcrowding the pan or undercooking the butter are the usual culprits. Use medium heat and cook in batches if needed—each piece needs space to crisp. Also, pat celery dry before frying and use fresh butter (water content causes steaming). For extra insurance, broil for 1 minute after pan-frying.
How can I adjust the spice level for kids?
Reduce the tomato paste to 1 tbsp and omit the mushrooms—they add natural earthiness. For extra mildness, blend the broth until completely smooth and strain out any visible particles. The shrimp can stay (just cook them through), but serve them on the side so kids can add them if they're feeling brave.
What's the secret to making the broth taste like Benihana's?
The kombu-bonito combo is non-negotiable for that signature oceanic depth. For extra restaurant-style flavor, add 1/4 tsp white miso paste to the velouté or finish with 1 tsp toasted sesame oil. The slow simmer (never boiling) and proper straining remove bitterness while preserving umami. Don't rush—Benihana's version develops over 20+ minutes of gentle cooking.
Can I use store-bought dashi instead of kombu/bonito?
Yes, but expect less complexity. Choose a high-quality dashi powder (like Honten) and use 1 tbsp per 4 cups water. For better results, toast 1 tsp bonito flakes** separately and strain them into the broth. The kombu's natural sweetness and kombu's texture are hard to replicate—homemade always wins for depth.
