Soy Sauce Mayonnaise Recipe: Umami-Rich Spread for Burgers and Fries

This umami-rich spread transforms basic burgers and fries into something extraordinary. The combination of savory soy sauce and creamy mayonnaise creates a balanced condiment that enhances every bite.

Simple to make with just two ingredients, this versatile sauce comes together in minutes. Store it in the fridge for up to a week to use whenever a dish needs a flavor boost.

Ingredients for Soy Sauce Mayonnaise

Creamy, salty, and endlessly adaptable for burgers, fries, and more beyond.

The mayonnaise is the foundation—Duke’s or Hellmann’s deliver the right consistency and neutral base. Soy sauce choice matters: Kikkoman or Yamasa offer reliable quality. For a richer finish, toasted sesame oil from Kadokawa adds depth without overpowering. Look for soy sauce labeled ‘naturally brewed’ for optimal flavor complexity.

No mayonnaise? Vegan mayo works identically. Skip the honey and use agave or maple syrup for sweetness. Out of Dijon? Yellow mustard at half the amount substitutes fine. For a spicier kick, add a dash of sriracha or a pinch of cayenne. The garlic powder can be swapped for fresh minced garlic (1 clove) if preferred.

Store in an airtight container in the fridge for up to 1 week. The flavors meld and deepen after a day. If separating occurs, a quick stir restores the emulsion. Not suitable for freezing.

Step-by-Step Instructions for Soy Sauce Mayonnaise

This method ensures a perfectly balanced umami spread with a smooth, creamy texture every time.

Step 1: Combine the Base Ingredients

In a medium mixing bowl, add the 1 cup Mayonnaise and 2 tbsp Soy Sauce. Using a whisk, blend them together until the soy sauce is fully incorporated and the mixture takes on a uniform light brown color with no streaks.

This initial combination creates the foundation of your spread. The soy sauce should distribute evenly throughout the mayonnaise, which may take 30-45 seconds of vigorous whisking. You’ll notice the texture becomes slightly looser as the soy sauce emulsifies with the mayonnaise.

Step 2: Add Flavor Enhancers

To the bowl, add the 0.5 tsp Garlic Powder, 1 tsp Dijon Mustard, and 1 tsp Honey. These ingredients add complexity: the garlic powder provides depth, the mustard introduces a subtle tang, and the honey balances the saltiness with a touch of sweetness.

Whisk again for another 30 seconds until all ingredients are fully combined. The mixture should appear smooth and slightly glossy, with the mustard and honey completely dissolved into the base. Taste briefly to ensure the flavors are beginning to meld—you should detect a harmonious blend of savory, tangy, and sweet notes.

Step 3: Incorporate Finishing Touches

Add the 1 tsp Lemon Juice, 0.5 tsp Sesame Oil, and 0.25 tsp Black Pepper to the bowl. The lemon juice brightens the spread, the sesame oil introduces a rich, nutty aroma, and the black pepper adds a mild heat that complements the umami.

Whisk for a final 20-30 seconds until the mixture is completely smooth and all ingredients are evenly distributed. The sesame oil, in particular, should not separate or pool on the surface. The finished spread will have a creamy, cohesive texture with a glossy sheen, and its color will deepen slightly to a warm caramel hue.

Step 4: Rest and Serve

Transfer the soy sauce mayonnaise to an airtight container. Let it rest at room temperature for 10-15 minutes to allow the flavors to fully meld together. This brief resting period ensures that the garlic powder hydrates and the sesame oil integrates seamlessly.

Once rested, give it a final stir and serve immediately, or refrigerate for up to 5 days. The spread will thicken slightly when chilled, so let it sit at room temperature for 5-10 minutes before serving to restore its creamy consistency. Use it as a dip, sandwich spread, or sauce—its versatility makes it perfect for burgers, fries, or as a flavorful addition to wraps.

Dietary Considerations for These Flavors

Gluten-Free Option

This spread can easily be gluten-free by swapping regular soy sauce with tamari or a certified gluten-free soy sauce like San-J. Tamari has a deeper flavor that works beautifully. 💛

Vegan Adaptation

Use vegan mayonnaise brands like Just Mayo or Hellmann’s Vegan instead of traditional mayo. Replace honey with agave syrup or maple syrup to maintain the sweetness balance.

Low-Sodium Version

Opt for low-sodium soy sauce and reduce the amount to 1 tbsp. Add a pinch of salt to taste if needed. The Dijon mustard and lemon juice will still provide plenty of flavor.

Dairy-Free Assurance

This recipe is naturally dairy-free as written. Just ensure your mayonnaise doesn’t contain milk derivatives. Duke’s and Hellmann’s are both dairy-free and work perfectly for this creation.

Allergen Note

Contains egg (from mayonnaise) and potentially wheat (from soy sauce). For egg-free versions, use egg-free mayo like Nascoya. Always check labels for cross-contamination warnings. 🔥

Keto-Friendly Tweak

This spread fits well into keto diets as is, with only 1g net carbs per tablespoon. Skip the honey entirely or use a sugar-free sweetener like allulose to further reduce carbs.
