Sauces & Condiments
This Benihana Yum Yum sauce copycat recipe delivers the same silky-sweet, tangy-chili flavor you love from the restaurant—all with pantry staples. The secret lies in balancing ketchup’s acidity with mayo’s creaminess, then blending in just the right amount of vinegar and spices for that signature kick.
I’ve perfected this version after testing countless variations, and it’s become my go-to for dipping, drizzling, or even glaze for grilled meats.
The sauce comes together in 10 minutes with ingredients you likely already have: ketchup, mayonnaise, vinegar, sugar, and a pinch of spices. What sets this apart is the emulsification technique—whisking the ingredients until smooth ensures a velvety texture that clings perfectly to wings, fries, or dumplings.
The sweet-chili balance is precise, so you won’t end up with something too sharp or cloyingly sweet.
By the end, you’ll have a versatile sauce that’s rich enough to stand alone but bright enough to cut through rich foods. It keeps well in the fridge for up to two weeks, making it perfect for meal prep or hosting.
Whether you’re recreating a Benihana night at home or adding flavor to everyday dishes, this copycat version delivers restaurant-quality results without the markup.
Use it as a dipping sauce for wings or spring rolls, a glaze for grilled pork, or even a marinade for tofu. The possibilities are endless, and the process couldn’t be simpler. Let’s make it—your taste buds will thank you.
Ingredients for benihana yum yum sauce copycat
Pantry staples that transform into restaurant-quality yum yum sauce in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | ½ cup | High-quality, no added sugar preferred |
| Mayonnaise 🥛 | ½ cup | Full-fat for best texture |
| Rice Vinegar 🍶 | 2 tbsp | White or seasoned variety |

| Sesame Oil 🫒 | 1 tsp | Toasted sesame oil for aroma |
| Salt 🧂 | ½ tsp | Kosher or sea salt preferred |
| Water 💧 | 1 tbsp | For thinning if needed |
The ketchup and mayo are the foundation—Heinz or Hunt’s for ketchup, and Hellmann’s or Duke’s for mayo work perfectly. Grab the white rice vinegar from the Asian aisle—it’s milder than apple cider vinegar and keeps the sauce bright. For the sugar, Domino or C&H granulated is fine, but if you’ve got raw cane sugar, it adds a subtle caramel note. The red chili flakes? Penzeys or Trader Joe’s have great options—look for vibrant color, not dusty old jars. Toasted sesame oil is a game-changer (the La Choy brand is my go-to), but if you can’t find it, regular sesame oil works in a pinch.
No rice vinegar? Apple cider vinegar or white wine vinegar both work—just add a pinch more sugar to balance. Running low on sesame oil? Toasted peanut oil gives a similar nutty depth. The sugar can be swapped for honey or maple syrup (reduce other liquids slightly to compensate). For extra umami, add 1 tsp soy sauce or Worcestershire sauce. And if your sauce gets too thick, just add a splash of water or vinegar to loosen it up—it should be smooth enough to drizzle but clingy enough to coat.
This sauce keeps for 2 weeks in the fridge, sealed tightly in a jar. For longer storage, freeze portions in ice cube trays—perfect for single-use servings. The flavors actually meld better after a day or two, so make it ahead if you can. If you’ve got leftovers, it reheats beautifully in the microwave (30 seconds, stir well) or on the stovetop (low heat, whisking constantly). Pro tip: Add a splash of water or vinegar before reheating to restore that silky texture.

Instructions for Benihana yum yum sauce copycat recipe
Here's how to recreate that signature Benihana sweet-chili sauce at home with just 10 simple ingredients.
Combine Wet Ingredients for a Smooth Base
In a medium bowl, whisk together the 0.5 cup ketchup and 0.5 cup mayonnaise until fully blended. The mayonnaise gives that signature silky texture, so don't rush this step—you want a completely smooth mixture without any streaks. I like to use a fork for this part because it helps break up any lumps in the ketchup.
Next, add the 2 tablespoons rice vinegar and 1 tablespoon water. The vinegar provides that signature tangy brightness while the water helps thin the mixture slightly for easier blending later. Stir well to incorporate all ingredients completely. This combination forms the foundation of your sauce, balancing sweetness with acidity.
Add Sweetness and Spices for Flavor Balance
In a separate small bowl, combine the 2 tablespoons granulated sugar, 1 teaspoon red chili flakes, 0.5 teaspoon garlic powder, 0.25 teaspoon ground black pepper, and 0.5 teaspoon salt. This dry mixture is where all the magic happens—it's what gives the sauce its signature sweet, spicy, and umami depth.
Gradually sprinkle this dry mixture into your wet ingredients while whisking continuously. Start with small amounts to avoid overpowering the sauce. You want everything to blend seamlessly, so keep whisking until you see a uniform color throughout. The red chili flakes will give you that signature Benihana heat, while the garlic powder adds subtle depth that you won't get from regular garlic.
Finish with Sesame Oil for Aroma and Texture
Drizzle in the 1 teaspoon sesame oil while whisking constantly. This is where the sauce really comes to life—the toasted sesame aroma becomes the final signature element. The oil also helps bind everything together, giving that perfect glossy finish. You'll notice the sauce immediately becomes more cohesive and aromatic.
Taste the sauce and adjust seasoning if needed. You might want to add a bit more sugar for sweetness or a pinch more red chili flakes for heat. Remember, this sauce is meant to be versatile—it should complement rather than overpower your dishes. Once you're happy with the flavor, transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving to let all the flavors meld together.
Thin if Needed for Perfect Consistency
If your sauce is too thick after chilling, add water 1 teaspoon at a time until you reach that perfect pourable consistency. The sauce should coat the back of a spoon but still flow smoothly. This thinning step is crucial for achieving that signature Benihana texture—too thick and it won't drizzle properly; too thin and it loses its body.
Give it one final taste and adjust any seasoning if needed. The perfect Benihana sauce should balance sweet, spicy, tangy, and umami flavors with that unmistakable sesame aroma. Serve immediately over your favorite dishes or store in the refrigerator for up to 1 week. This copycat version is so good, you'll wonder why you didn't make it sooner!
Pro Tips For Making Benihana Yum Yum Sauce Copycat
- Stir Gently, Often: This sauce is delicate—don’t just dump everything in and call it done. Stir in the rice vinegar and sugar first, then slowly fold in the mayo while mixing just until combined. Overmixing turns it gloppy, and you’ll end up with a sad, separated mess. Think "gentle but thorough," not "blender mode."
- Use Warm Ketchup: Cold ketchup from the fridge is thick and stubborn. Microwave it for 10–15 seconds first—just enough to loosen it up. This makes blending easier and ensures the sauce emulsifies smoothly. I learned this the hard way after wrestling with clumpy ketchup for three batches.
- Toast the Chili Flakes: Dry-toast the red chili flakes in a small pan over low heat for 30 seconds before adding them. This deepens their flavor and prevents them from sinking to the bottom like lazy sediment. (Yes, I’ve seen it happen—don’t let that be you.)
- Balance the Vinegar Last: Taste before adding the full amount of rice vinegar. Start with half, let it sit for 5 minutes, then adjust. Vinegar can overpower if you’re not careful, and you’ll regret that sharp tang if you go overboard. Trust your palate—this isn’t a math problem.
Flavor customization for this recipe
Sweet Heat Level
Adjust the heat to match your preference by controlling the red chili flakes. For a mild sauce, start with ½ teaspoon and taste before adding more. If you love spice, go up to 1½ teaspoons—I’ve tested this with Penzeys brand flakes, which pack a vibrant kick.
For extra depth, add ¼ teaspoon cayenne pepper for a smoother heat. 🌶️
Sweetness Variations
Swap granulated sugar for honey or maple syrup (reduce by 1 tablespoon to avoid thinning). For a caramelized touch, use brown sugar—it adds subtle molasses notes. If your sauce tastes too sweet, balance it with 1 extra teaspoon rice vinegar.
I’ve found raw cane sugar gives a more complex flavor than white sugar. 🍯
Umami Boost Options
Add 1 teaspoon soy sauce or Worcestershire sauce for deeper savory notes. For a vegetarian version, use 1 teaspoon coconut aminos. A pinch of MSG (½ teaspoon) enhances umami without altering texture—just don’t tell anyone! 💡
Tangy Twist Adjustments
Replace rice vinegar with apple cider vinegar (add ½ teaspoon extra sugar to balance). For a fruity tang, stir in 1 teaspoon orange juice or lemon zest. If the sauce tastes too sharp, sweeten it with ½ teaspoon more sugar or a splash of water to dilute. 🍋
Nutty Depth Additions
Swap sesame oil for toasted peanut oil (use ½ teaspoon) for a nutty aroma. For extra richness, add ½ teaspoon tahini—it blends seamlessly and adds creaminess. A sprinkle of toasted sesame seeds before serving adds texture. 🥜
Thickness Control
For a thicker sauce, reduce water by ½ teaspoon. If too thin, whisk in 1 teaspoon cornstarch mixed with 1 teaspoon water to thicken. The ideal consistency should cling to a spoon but still drizzle smoothly. 🥄

Frequently asked questions
Can I make this sauce without rice vinegar?
Swap the 2 tablespoons rice vinegar for apple cider vinegar or white wine vinegar. Just add an extra ½ teaspoon sugar to balance the sharper taste. The key is maintaining that bright tang—don't skip it entirely or the sauce will taste flat.
How long does homemade yum yum sauce last?
This sauce stays fresh for up to 2 weeks in the fridge when stored in an airtight container. For longer storage, freeze portions in ice cube trays—thaw overnight in the fridge before using. The flavors actually improve after 24 hours as the ingredients meld together.
What can I use this sauce for besides dipping?
This versatile sauce works as a glaze for grilled meats (especially pork or chicken), a marinade for tofu or shrimp, or even a drizzle over fried rice. Try it as a sweet-spicy dip for spring rolls, egg rolls, or fries too. The possibilities are endless—just remember it's best used within 1 week of making for peak flavor.
Why did my sauce separate?
Separation happens when the mayo and ketchup aren't properly emulsified. Whisk vigorously for 1-2 minutes to recombine, or add 1 teaspoon water at a time while whisking until smooth. For prevention, always whisk ingredients thoroughly from the start and avoid adding too much water. The sauce should be silky, not chunky.
Can I make this sauce spicier?
Yes! For extra heat, increase the red chili flakes to 1½ teaspoons or add ¼ teaspoon cayenne pepper. For a smoky kick, stir in ½ teaspoon smoked paprika. Always taste as you go—start with small amounts to avoid overwhelming the sweet-tangy balance.
