How to Make the Best Fish Tacos Sauce

Step 1: Combine Ingredients

In a small mixing bowl, combine the sour cream, mayonnaise, lime juice, sriracha, garlic powder, salt, and ground cumin.

Step 2: Mix Thoroughly

Whisk everything together until completely smooth and well incorporated. Make sure there are no pockets of spices or streaks of sriracha remaining.

Step 3: Taste and Adjust

Give it a quick taste and adjust seasoning if needed. Want more heat? Add sriracha. Need more tang? A bit more lime juice will do the trick.

Step 4: Chill

Transfer the sauce to an airtight container and refrigerate for at least 2 hours before serving. This resting time is crucial for the flavors to develop and meld together.

Pro Tips for Making the Recipe

Quality Ingredients Matter: Use fresh lime juice rather than bottled for a brighter, more vibrant flavor.
Patience Pays Off: The 2-hour chilling time isn’t just a suggestion—it’s when the real magic happens as flavors develop and harmonize.
Consistency Control: If you prefer a thicker sauce for dolloping, use a bit more sour cream. For a thinner, more drizzable sauce, add a splash of water or extra lime juice.
Taste as You Go: Everyone’s preference for heat and acidity differs, so don’t be afraid to adjust the sriracha and lime juice to suit your taste.
Room Temperature Serving: While the sauce needs to be stored in the refrigerator, taking it out about 15 minutes before serving allows the flavors to wake up and shine.

How to Serve

This versatile sauce elevates so many dishes beyond just fish tacos:

Perfect Pairings

Drizzle over grilled fish tacos with cabbage slaw and avocado for the classic experience.

Beyond Tacos

Use as a zesty dip for sweet potato fries, spread on fish burgers, or dollop onto grilled shrimp skewers.

Grain Bowl Topper

Make Ahead and Storage

Storing Leftovers

Store the sauce in an airtight container in the refrigerator for up to 2 weeks. The flavors will continue to develop over the first few days.

Freezing

This sauce doesn’t freeze well due to the dairy content, which can separate upon thawing.

Reheating

No reheating needed! Simply give it a good stir before using if it’s been sitting in the refrigerator for a while.
