Soups & Stews
This Benihana soup recipe copycat delivers the same crispy celery crowns and smoky tomato velouté that made the restaurant famous. The secret lies in a carefully balanced dashi-miso broth infused with garlic and ginger, then topped with perfectly fried celery and corn for that signature crunch.
I've recreated the dish after years of studying their technique—no shortcuts, just restaurant-quality results at home.
The foundation is a rich, umami-packed broth that simmers for hours, developing deep flavors from dried shiitake mushrooms, kombu, and a touch of miso paste. While it cooks, you'll prepare the crispy celery crowns by frying them in oil until golden—this is what sets this soup apart from typical ramen.
The technique is simple but requires patience to achieve that perfect texture.
What you'll end up with is a bowl of soup that's visually stunning and packed with layers of flavor: the smoky-sweet velouté, the crispy celery crowns that shatter with each bite, and the fresh toppings of corn, mushrooms, and green onions.
The aroma alone will bring back memories of your favorite Benihana visit, but with the convenience of making it at home.
This recipe stays true to the original while offering flexibility—swap in different vegetables or adjust the spice level to suit your taste. The key is in the broth and the crispy toppings, both of which require time but deliver restaurant-quality results. Let's get started on recreating this iconic dish.
Ingredients for benihana soup recipe copycat
Crispy celery crowns and smoky velouté—here's how to recreate Benihana's iconic soup at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Dried Shiitake Mushrooms 🍄 | ½ oz | Rehydrated in hot water |
| Kombu Seaweed 🌊 | 2 pieces | Dried, 4x6 inches each |
| Celery Stalks 🧅 | 4 whole | Large, for crispy crowns |
| Sweet Corn Kernels 🌽 | 1 ½ cups | Fresh or frozen, thawed |
| Fresh Ginger 🧄 | 1 tbsp | Grated, not powdered |
| Garlic Cloves 🧄 | 6 cloves | Minced, not powdered |
| White Miso Paste 🍶 | 2 tbsp | High-quality, not instant |
| Tomato Paste 🍅 | ½ cup | Smooth, not chunky |
| Dashi Granules 🍜 | 1 tbsp | Or 1 cup homemade dashi |
| Vegetable Oil 🫒 | 1 ½ cups | For frying celery |
| Green Onions 🧅 | ¼ cup | Sliced, for garnish |
| Dried Shiitake Mushrooms 🍄 | ¼ cup | Sliced, for garnish |
| Sea Salt 🧂 | 1 tsp | Kosher preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Soy Sauce 🍶 | 1 tbsp | For finishing |
The kombu and dried shiitake are non-negotiable for that authentic umami depth. Japanese grocery stores like H Mart or Asian markets carry the best quality—look for kombu that's still pliable, not brittle. If you can't find kombu, dried bonito flakes work in a pinch, but it won't be identical. Fresh ginger and garlic need to be freshly grated and minced—powdered versions won't cut it. For the miso, White Miso from Marukome is my go-to, but any high-quality white miso will do. Pro tip: soak the kombu in cold water for 10 minutes before simmering to draw out maximum flavor.
No kombu? Dried wakame seaweed in a pinch, but reduce to half the amount. Short on shiitake? Cremini mushrooms work, but they won't have the same earthy depth. The celery crowns are the star—use thick celery stalks (about 1-inch diameter) for best results. If your corn is frozen, thaw it completely first. For the velouté, San Marzano tomatoes are ideal, but any good-quality canned tomatoes will work. The tomato paste should be smooth—chunky varieties can make the broth grainy. Want extra smokiness? Add a pinch of smoked paprika to the broth.
This soup tastes even better the next day—broth flavors meld beautifully. Store the broth separately from toppings in the fridge for up to 5 days. The crispy celery crowns lose their crunch after 2 days, so fry them fresh when serving. Freeze the broth (without toppings) for up to 3 months. For meal prep, I keep the broth base ready and assemble bowls fresh with crispy toppings. Garnishes like green onions and sliced shiitake keep for 5 days in the fridge—wrap them in damp paper towels to maintain freshness.

A single pack of dried mushrooms and a sheet of seaweed goes a long way, and the rest of the ingredients are pantry staples. It’s the kind of dish that makes grocery day feel like a win.
- No-Fuss Simmer: I swear by this recipe because it’s basically set-it-and-forget-it. Soak those dried shiitakes and kombu in hot water for 20 minutes—no chopping, no fuss—then toss everything in one pot. The mushrooms plump up on their own while the broth builds flavor without me hovering over the stove.
- Umami Bomb: Between us, the combo of shiitakes, kombu, and fresh ginger hits different. That deep, savory punch from the mushrooms and seaweed? It’s like Benihana’s signature richness but with half the ingredients. The celery and corn add just enough brightness to keep it from being too heavy.
- Office Lunch Hero: This soup is my go-to for meal prep because it reheats like a dream. Pack it in a thermos for work, or make a big batch on Sunday—it tastes just as good cold the next day. My coworkers think I’m a genius when I bring it in; they never guess how simple it is.
Step-by-step instructions for Benihana-style crispy celery crowns and tomato velouté
This copycat version delivers restaurant-quality texture and flavor with precise techniques.
Prepare the Crispy Celery Crowns
Trim the bottoms of the 4 whole celery stalks to create flat surfaces. Using a sharp chef's knife, carefully slice off the leafy tops and set aside for garnish later. Cut each stalk diagonally into 1-inch thick rounds—these will become your crispy crowns.
Heat the 1.5 cups vegetable oil in a deep skillet to 350°F using a thermometer. Fry the celery rounds in batches for 2-3 minutes per side until they turn a deep golden brown. Remove and drain on paper towels. The celery should be crispy enough to hold its shape when stacked—this is your key to that signature Benihana crunch.
Build the Smoky Tomato Velouté Base
In a large pot, combine the 0.5 cup tomato paste, 1 tbsp dashi granules, 1 tbsp grated fresh ginger, and 6 minced garlic cloves. Add 2 cups water and bring to a gentle simmer over medium-low heat. Stir constantly for 10 minutes until the mixture thickens slightly and develops a rich, smoky aroma.
Add the 1.5 cups sweet corn kernels and 0.5 oz rehydrated dried shiitake mushrooms (chopped). Simmer for another 5 minutes until the corn is tender but still holds its shape. The soup should have a velvety texture with visible corn kernels—this is the signature texture of Benihana's version.
Create the Umami Depth with Kombu and Miso
Place the 2 pieces kombu seaweed in a small bowl and cover with hot water. Let it steep for 10 minutes to infuse the water with oceanic depth. Add this kombu water to your soup along with the 2 tbsp white miso paste. Stir gently over low heat for 3-4 minutes until the miso dissolves completely—this creates that signature umami richness.
Season with the 1 tsp sea salt and 0.5 tsp black pepper. Taste and adjust—you want a balance of sweetness from the corn, umami from the miso, and a touch of saltiness. The soup should coat the back of a spoon but remain light enough to let the crispy celery shine.
Assemble and Finish with Crispy Toppings
Ladle the warm soup into bowls, placing 2 crispy celery crowns on top of each serving. Drizzle with the 1 tbsp soy sauce and garnish with the sliced green onions and 0.25 cup dried shiitake mushrooms. The contrast between the warm, velvety soup and the crispy celery is what makes this dish so special—each bite should deliver that satisfying crunch.
Serve immediately while the celery crowns are still crispy. The soy sauce will enhance the umami notes while adding a final layer of complexity. This copycat version stays true to the restaurant's signature combination of textures and flavors.
Pro Tips For Making Benihana Soup Recipe Copycat
- SOAK SHIITAKES OVERNIGHT: Dried shiitakes need serious hydration—toss them in hot water for 30 minutes, then finish soaking in cold water overnight. I learned this the hard way: rushing them leaves them chewy and underwhelming, while proper soaking makes them tender and rich.
- TOAST KOMBU FIRST: Crisp the kombu in a dry pan for 30 seconds before adding liquid—it deepens the umami and prevents that slimy texture. Sounds weird, but it works: the edges turn golden, and the broth gains a complexity you won’t get otherwise.
- SIMMER LOW AND LONG: This isn’t a quick broth—push for at least 45 minutes of gentle simmering after everything’s in. I used to rush it, and the flavors were always flat; patience pays off with a depth that shortcuts can’t replicate.
- GINGER SLICE THIN, NOT GRATED: Use a mandoline for paper-thin slices instead of grating—it melts cleanly without bitterness. Grated ginger turns mushy and overpowers; thin slices dissolve perfectly while keeping the dish bright and aromatic.
Make-ahead tips for this benihana soup recipe copycat
Broth Prep Ahead
The secret to restaurant-quality flavor is a well-developed broth. Make your dashi-kombu-miso base up to 3 days in advance—it only gets better as the flavors meld.
Store it in an airtight container in the fridge, covered with a lid and plastic wrap pressed directly on the surface to prevent skin formation. When reheating, warm it over low heat with a splash of water to restore its velvety texture. 💫
Celery Crown Prep
Celery crowns lose their crispiness fast, so fry them fresh when serving. However, you can pre-cut the celery rounds up to 1 day ahead and store them in a single layer on a baking sheet in the fridge.
Keep them dry to prevent sogginess. When ready to fry, pat them completely dry with paper towels before hitting the hot oil. This shortcut saves time without sacrificing texture.
Topping Assembly
Prep all your garnishes—green onions, shiitake mushrooms, and corn—1 day ahead and store them in separate airtight containers in the fridge. Wrap the shiitake slices in a damp paper towel to keep them fresh.
When assembling bowls, keep the crispy celery crowns separate until serving to maintain their crunch. This way, you only need to fry the celery and assemble when ready to eat. ✨
Freezer-Friendly Base
The broth base freezes beautifully for up to 3 months. Portion it into 1-cup containers before freezing—this makes reheating and serving effortless. When ready to use, thaw overnight in the fridge, then reheat gently on the stovetop.
Avoid microwaving, as it can break down the delicate texture. Add fresh crispy celery crowns and garnishes just before serving for the best experience.
Meal Prep Timeline
Here’s my 3-day prep plan for stress-free Benihana soup nights: Day 1 - Make and freeze broth. Day 2 - Prep all toppings (chop veggies, slice shiitake). Day 3 - Fry celery crowns fresh in the morning, then assemble bowls when hungry.
This keeps the dish restaurant-quality while minimizing last-minute work. The key is keeping the crispy elements separate until serving. 💡

Frequently asked questions
Why does Benihana soup have crispy celery crowns?
The crispy celery crowns are the signature element that sets this soup apart from traditional ramen or miso soup. They provide a satisfying textural contrast to the warm, velvety broth—each bite delivers that satisfying crunch while the soup melts on your tongue. This technique originated in Japanese teishoku (set meal) culture where crispy toppings elevate simple dishes.
Can I make this soup without kombu or miso?
You can substitute, but it won't be authentic. For kombu, try dried wakame seaweed (reduce to 1 piece) or bonito flakes (1 tbsp). For miso, use 1 tbsp soy sauce + 1 tsp white wine to mimic umami, though the flavor will be different. The crispy celery and tomato velouté will still shine, but the depth of flavor will be compromised.
How do I get the celery crowns extra crispy?
Three key secrets: 1) Use thick celery stalks (1-inch diameter), 2) Fry at exactly 350°F in small batches, and 3) Drain on a wire rack (not paper towels) to remove excess oil. Pat dry with paper towels right after frying, then store in a single layer in the fridge until serving. The celery should be golden brown and hold its shape when stacked.
What if I don't have a thermometer for frying?
Test the oil by dropping in a small piece of celery—it should sizzle and turn golden in 30-45 seconds. If it browns too quickly, the oil's too hot; if it stays pale, it needs more time to heat. For best results, use a deep skillet and maintain medium-high heat while frying. The celery should be crispy enough to stand up when stacked.
Can I make this soup spicier?
Add 1/2 tsp chili flakes or 1 tbsp sriracha to the broth while simmering, or drizzle with extra soy sauce (which has natural heat). For authentic heat, try 1 tsp gochujang (Korean chili paste) mixed with the miso paste. Start with small amounts—these sauces pack serious flavor.
