About This Fish Taco Sauce

The signature of a memorable fish taco is a delicious, creamy sauce that complements the mild flavor and crisp texture of white fish.

The classic recipe centers around a handful of kitchen staples: mayonnaise, sour cream, lime juice, and spices. In minutes, you’ll craft a sauce with just the right balance of tang, heat, and richness—perfect for drizzling, dipping, or spreading.

Ingredients You’ll Need

This fish taco sauce comes together quickly with common ingredients you likely already have. Here’s what makes it great:

  • Mayonnaise: Provides a creamy, rich base. Use full-fat for the best texture.
