Easy Yum Yum Sauce

Featured in: Boost Your Dishes with Bold Flavors

This rich, tangy sauce nails the taste of Japanese steakhouses. It starts with creamy mayo and gets buttery smooth, flavored by garlic, paprika, and a sweet pinch. Let the ingredients chill together overnight for the signature punch. Avoid using light mayo—it won't be thick or creamy enough. Drizzle it on hibachi meals, your favorite seafood, or roasted veggies, or use it as a dip for a fun twist!

Whip up this super creamy, slightly sweet dipping sauce at home with just a handful of kitchen basics. It's that famous white sauce from Japanese steakhouses that makes everything taste better! Great on hibachi dishes or even simple sandwiches, this homemade version will turn your everyday meals into something you can't stop eating.

I started making this after watching my kids almost lick their sauce dishes clean during a teppanyaki dinner out. Now they ask for it every week, and it's become the star of our DIY "takeout" nights we do each Friday.

What You'll Need

  • Mayonnaise: This forms your creamy base – don't grab the light stuff as only regular mayo gives you the right thickness
  • Water: Just enough to get the perfect pourability without watering down the taste
  • Ketchup or tomato paste: Gives that hint of tanginess and the pretty light pink color
  • Melted butter: Adds that smooth, velvety feel and genuine restaurant touch
  • Garlic powder: Brings in some background flavor without being too strong
  • Sugar: Cuts through the sharpness with just a bit of sweetness
  • Paprika: Adds both that nice rosy tint and gentle smoky notes

How To Make It

Get Everything Ready:
Grab all your stuff and measure carefully since getting the balance right matters. Let your mayo sit out a bit so it's not cold, and always use the full-fat kind or your sauce might split.
Mix The Main Part:
Put your mayo in a bowl and drizzle in water bit by bit while stirring constantly. Go slow here to avoid any clumps forming in your sauce.
Put In The Good Stuff:
Now add your ketchup or tomato paste, melted butter, garlic powder, sugar, and paprika to your smooth mayo mix. Keep stirring until everything turns a nice even peachy color with no streaks showing.
Let It Sit:
Pour your sauce into a container with a good lid and stick it in the fridge overnight or at least 8 hours. This waiting part can't be skipped – it's when all the flavors really come together and the sauce gets that perfect thickness.

The real hidden trick with this sauce is definitely patience. The first time I made it, I served it right away and thought it was just okay. But when I tried the leftovers the next day – wow! It had completely changed. Giving it that overnight chill lets the garlic fully soak in and all the flavors blend together in a way you just can't rush.

How To Tell If You Got It Right

Most homemade versions don't quite match what you get at restaurants. That's because real Japanese steakhouse chefs mix their sauce days before serving it. The big secrets in this version are using regular mayo (not light) and giving it plenty of time in the fridge. When we did a side-by-side taste test, even my pickiest eaters couldn't tell the difference between this and the restaurant stuff.

Ways To Use It

This sauce works for way more than just steakhouse food. Try dunking fries in it, spreading it on a burger, or drizzling it over a bowl of rice and veggies. My favorite way to use it is coating crispy baked cauliflower and sprinkling some green onions on top. It's also great with spicy foods since the creaminess cools down the heat while adding extra flavor.

Keeping It Fresh

Keep your sauce in a container with a tight lid in the fridge for best results. The flavor actually gets better during the first day or two. After that, it stays good for about two weeks. If you see it separating a bit, just give it a quick stir. Don't leave it sitting out on the counter too long since the mayo can go bad. I wouldn't try freezing it either – it'll just separate and get weird when it thaws.

With just a few simple ingredients and a bit of waiting time, you can make a sauce that'll have everyone thinking you ordered takeout. Try it once, and I bet it'll become a regular in your kitchen rotation.

Frequently Asked Questions

→ Can I swap regular mayo for light mayo?

It's best not to. Light mayo makes the sauce thinner and less rich, so stick with good old full-fat mayo for that creamy, classic flavor.

→ How long do I need to chill the sauce?

Let it sit in the fridge for at least 8 hours. If you've got time, overnight (about 12–24 hours) is even better for letting the flavors come together.

→ How long can I keep the sauce in the fridge?

Store it in a sealed container in the fridge, and it should stay good for up to a week. Don't leave it out for too long since it has a mayo base.

→ What food goes best with this sauce?

It's amazing with hibachi-style meals, shrimp, chicken, steak, fried rice, or roasted veggies. Try it on sushi rolls or in rice bowls for added flair!

→ Can I adjust the spice levels?

You sure can! Add a dash of hot sauce, sriracha, or even a sprinkle of cayenne. Add a bit at a time until you hit your perfect heat level.

→ What can I use instead of tomato paste?

Ketchup works fine, or use a tablespoon of tomato sauce that's been slightly reduced. In a pinch, try a small amount of tomato powder for a similar effect.
