I used to think yum yum sauce was some kind of restaurant secret, like the chefs had a locked cabinet somewhere with a jug labeled “do not touch.”
Turns out it’s just mayo, ketchup, and a handful of pantry staples whisked together in about five minutes.
I found this out the hard way after ordering hibachi three weekends in a row, mostly for the sauce, and my husband finally looked at me and said “you know you can just make that at home, right?”
I did not know that. I felt a little betrayed by my own kitchen.
So I tested it. Then I tested it again with less sugar. Then again with smoked paprika instead of regular because I ran out. That third batch is the one that stuck, and it’s the one I’m sharing with you today.
Here’s the thing that surprised me most. This sauce isn’t some complicated emulsion that takes years of practice. It’s a mayo-based sauce with a few pantry staples stirred in, and the whole thing comes together faster than it takes to order takeout.
Once I had the ratios figured out, I started making a batch every single week. It’s gone on chicken, on fries, on rice bowls, and once, embarrassingly, straight off a spoon while standing at the fridge.
This hibachi-style sauce is creamy, a little tangy, faintly sweet, and just smoky enough to make you close your eyes on the first bite. It takes less time to make than it takes to preheat your oven.
Side Note: If you love sauces that do all the heavy lifting for you, you’ll also want to try my garlic aioli recipe next. Same energy, different flavor lane.

No blender, no food processor, no special equipment. Just a bowl and a whisk.
Pro Tips
I made this sauce more times than I’d like to admit while dialing it in, so let me save you the trial and error.
- Melt the butter first and let it cool slightly. If it’s too hot when it hits the mayo, it can make the sauce look a little separated instead of silky.
- Add the water slowly. Start with 2 tablespoons and only add more if you want a thinner, more pourable consistency. It’s much easier to thin a sauce out than to thicken it back up.
- Let it chill for at least 30 minutes before serving. I know it’s tempting to eat it right away, but the flavors need a little time to actually get to know each other. Fresh out of the bowl, it tastes fine. After a chill, it tastes like the real thing.
- Smoked paprika, not regular, is the move. This was the single biggest upgrade in my testing. Regular paprika gives you color. Smoked paprika gives you that unmistakable hibachi flavor.
- Taste as you go, especially with the cayenne. A pinch adds a nice background warmth without turning this into a spicy sauce. Add more only if you actually want heat.
- Use a good quality mayonnaise. Since it makes up most of the sauce, the flavor of your mayo really does carry through. I stick with a full-fat, neutral-tasting brand rather than anything with added flavors.
How to Make Yum Yum Sauce
- Add the mayonnaise and ketchup to a medium mixing bowl.
- Pour in the rice vinegar, sugar, garlic powder, and smoked paprika.
- Whisk everything together until it’s fully combined and smooth.
- Slowly drizzle in the melted butter while whisking. This helps it blend in evenly instead of pooling.
- Add 2 tablespoons of water and whisk again. Check the consistency, then add more water, a teaspoon at a time, until it’s as thin or thick as you like.
- Stir in the cayenne pepper if you’re using it.
- Cover the bowl and refrigerate for at least 30 minutes before serving.
That’s genuinely the whole process. No cooking, no special technique, just mixing and patience.
Substitutions and Variations
Not everyone keeps the exact same pantry, so here’s how to make this work with what you’ve got.
| Original | Swap | Notes |
|---|---|---|
| Mayonnaise | Greek yogurt (half and half) | Lighter, slightly tangier |
| Ketchup | Tomato paste + splash of sugar | Deeper tomato flavor |
| Rice vinegar | Apple cider vinegar | Slightly sharper taste |
| Butter | Avocado oil | Great for dairy-free versions |
| Smoked paprika | Regular paprika + tiny pinch of liquid smoke | Backup option if you’re out |
If you want it spicier, a few dashes of sriracha works beautifully. If you want it sweeter, an extra half teaspoon of sugar does the trick without overpowering everything else.

Make Ahead Tips
This sauce is actually better the next day, so making it ahead isn’t just convenient, it’s basically the recommended method.
You can whisk it together up to 5 days before you need it and store it covered in the fridge. Give it a quick stir before serving since it can settle slightly.
Side Note: I like making a double batch on Sunday so I have it ready for stir fry night, taco night, and random 10pm fridge-raiding sessions throughout the week.
Nutritional Snapshot
Here’s a rough breakdown per 2-tablespoon serving. Keep in mind this will shift depending on the exact brand of mayo and ketchup you use.

If you’re watching calories, the Greek yogurt swap mentioned above cuts this down noticeably without sacrificing much flavor.
Meal Pairings
This sauce is one of those rare condiments that makes almost anything taste like it came from a restaurant.
- Hibachi-style fried rice with veggies and egg
- Grilled chicken or shrimp skewers
- Crispy air fryer french fries
- Sushi bowls or homemade sushi rolls
- Roasted or steamed vegetables, especially zucchini and broccoli
Basically, if it needs a little something extra, this sauce is that something.
I’ve also started using it as a dip for dumplings and a spread on burgers, which sounds unconventional but tastes incredible. Once you have a jar of this in your fridge, you’ll find yourself reaching for it more often than you’d expect.
Leftovers and Storage
Store any leftover sauce in an airtight container in the refrigerator. It will keep well for up to 5 days.
I don’t recommend freezing this one. Mayonnaise-based sauces tend to separate once thawed, and the texture just isn’t the same.
No reheating needed here either. Just pull it out of the fridge, give it a stir, and serve it cold or at room temperature.
