    This nuoc cham chay is a must-have dipping sauce for many Vietnamese vegan dishes like bi cuon chay or bun bi chay. It’s a great alternative dipping sauce to replace nuoc mam cham, which is fish sauce-based. It adds a bright and tart flavor with a bit of umami and sweetness.

    • Nuoc Cham Chay (Vietnamese Vegan Dipping Sauce)

    Ingredients & Notes

    Ingredients for Vietnamese vegan dipping sauce on a table.

    Soy Sauce - I use Kikkoman all-purpose, but you may also use less sodium soy sauce.

    White Sugar - If you prefer to use honey, do a 1:1 substitute (adding honey will make it non-vegan). 

    Hot Water - This helps to dissolve the sugar easily.

    Thai Red Chili Pepper - This is optional, but is great for a hint of spice.

    Instructions

    Steps to make nuoc cham dipping sauce.

    1). Add sugar to a bowl.

    2). Then add the hot water and stir until the sugar dissolves.

    5). Add in the garlic and thai chili. Taste the sauce and adjust it as pleased! 

    Pro Tips

    • The taste of nuoc cham chay should be a balance of sweet, tart, garlic and umami-ness. No one flavor should overpower another.
    • This recipe is a great base and can be adjusted to your taste. 
    • Make sure to add the chili in small increments, and adjust the spice level to your liking. Thai chili is very spicy.
    • Use warm or hot water, this will help dissolve the sugar better. 
    • Store in an airtight container, like a small mason jar in the refrigerator for up to 3 days.
