The mayonnaise base determines texture and richness. Duke’s or Hellmann’s deliver that classic creamy body without sweetness. For sriracha, Huy Fong is the gold standard—its balanced heat and garlic notes complement the lime perfectly. Look for limes with smooth, firm skins (they yield more juice) and avoid those with thick, pitted rinds. If using bottled lime juice, choose ReaLime for consistent quality.

No sriracha? Any hot sauce at a 1:1 ratio works—Tabasco adds vinegar tang, Cholula brings smokiness. Lime juice can be swapped for lemon juice at equal volume, though the flavor profile shifts slightly. For a vegan version, use Vegenaise or Just Mayo. Fish sauce isn’t traditional in all banh mi mayo, so soy sauce or coconut aminos (use ½ tsp) can substitute if needed.

Store in an airtight container in the fridge for 5-7 days. The flavors meld and intensify over time, so making it a day ahead is ideal. Stir before each use as the ingredients may separate slightly. Freezing isn’t recommended—it can cause the mayo to split.

Step-by-Step Instructions for Banh Mi Mayo

This foolproof method combines bold flavors with minimal effort for consistent results.

Step 1: Prepare the Aromatic Base

Mince the 2 cloves Garlic Cloves until finely textured—this ensures even distribution and maximum flavor infusion. I use a microplane for the 1 tsp Lime Zest to capture only the fragrant outer layer, avoiding the bitter white pith beneath.

The garlic and lime zest form the aromatic foundation of this spread. Combine them in a medium mixing bowl to let their flavors begin melding. The citrus oils from the zest will start to draw out the garlic’s pungency immediately.

Step 2: Build the Flavor Profile

To the garlic and zest mixture, add the 1 cup Mayonnaise, 3 tbsp Sriracha Sauce, 2 tbsp Lime Juice, and 1 tsp Granulated Sugar. The mayonnaise provides the creamy base that carries all the bold flavors.

Whisk these ingredients together until completely smooth and uniform in color. The lime juice will naturally separate slightly at first, but vigorous whisking ensures it emulsifies properly with the mayonnaise. You should see the mixture take on a pale orange hue from the sriracha.

Step 3: Incorporate the Umami Element

Add the 1 tsp Fish Sauce to the mixture. This is the secret ingredient that gives the spread its authentic depth. I recommend using a high-quality fish sauce like Red Boat for the cleanest flavor profile.

Whisk once more to fully integrate the fish sauce. The mixture should now have a balanced aroma—bright from the lime, spicy from the sriracha, and savory from the fish sauce. Taste and adjust the heat level if desired, though remember the flavors will meld and mellow slightly as it rests.

Step 4: Rest and Develop the Flavors

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This resting period allows the flavors to harmonize completely. The garlic will mellow slightly, the lime will brighten, and the heat from the sriracha will distribute evenly.

During this time, the sugar will fully dissolve and the fish sauce will work its magic, creating that signature umami punch that makes this spread irresistible. The mixture will also thicken slightly as it chills, making it easier to spread.

This spread keeps well in the refrigerator for up to 1 week in an airtight container. The flavors actually improve after 24 hours as they continue to develop.
