Yum Yum Sauce

Hibachi style Yum Yum sauce you can make right at home. Lather on any stir-fry, fried rice, or veggie dish. This sauce is so simple to put together, calls for simple pantry items, and can last a week in the refrigerator.

Servings 14 ounces


  • 1 Cup Mayonnaise
  • ¼ Cup Ketchup
  • 1 Tablespoon Melted Butter
  • 1 Tablespoon Granulated Sugar
  • ½ Tablespoon Garlic Powder
  • 1 teaspoon Paprika
  • 1 teaspoon Onion Powder
  • ½ teaspoon Salt
  • ¼ teaspoon Cayenne More if you want it spicy
  • ¼ Cup Water More or less depending on your desired consistency


  • Sriracha or Gochujang Sauce Adds more spiciness to it.


  • In a medium glass bowl whisk together the mayo, ketchup, and melted butter. We want to do this first so the butter gets incorporated right away before it gets cold and solidifies.
  • Add in sugar, salt, onion powder, garlic powder, paprika, and cayenne.
  • Mix well until everything is fully combined.
  • Add in ¼ cup of water and mix well. If it is still too thick for your liking, add a little more water until you reached your desired consistency. If it gets too thin just add in a little more mayo and ketchup.
  • Optional: Mix in Sriracha or gochujang to add some spiciness to it.
  • Can be used right away or chill in the refrigerator for 2 hours before serving. Give it a good mix and serve.


  • Make it Spicy: It already calls for a small amount of cayenne but it really isn't spicy. You can intensify it by adding in a bit more cayenne, chili sauce, siracha, or gochujang sauce. Keep in mind that as it chills it will develop the flavor and get spicier. You can always add the spicy sauces right before serving as well if you don't feel it's spicy enough.
  • Dairy-Free: This sauce still holds well without the butter. Feel free to leave it out and it will still taste amazing.
  • Kid-Friendly: My kids can even detect the cayenne and say it's too spicy. If I know they will eat it, I will typically leave the cayenne out. Or separate the sauce into two bowls and add the spicy stuff to our version and leave them some without.
Store the sauce in an air-tight container or jar and keep it in the refrigerator for up to a week. Give it a good stir right before serving as things can tend to settle.
This sauce does not hold up to freezing well. Mayonnaise is a combination of oil and egg and during the reheating process can become separated. If you feel like you will not use up all the sauce I would recommend cutting everything in half instead of making a full batch.
