Why you’ll love it

It’s about time I put my recipe for sauce for fish tacos on the blog! This creamy, bright, and delicately smoky sauce is the one I always generously drizzle on Fish Tacos, and by “generously” I mean “completely drench” since it’s just that tasty.

Homemade taco sauce is always best since it’s fresh, you know exactly what goes into it and can adjust to your tastes, and it is super simple to make from scratch. All you need is a few pantry staples and a fresh lime, and it’s ready in under 10 minutes for taco night!

What you’ll need

  • Mayo and sour cream – for the creamy base with a slight tang
  • Lime juice – a hint of fresh lime juice brightens it up
  • Sriracha – this give a little kick to the sauce
  • Seasoning – we’re using garlic powder, salt, and smoked paprika for that unbeatable flavor combo

Tools for this recipe

  • I like to make this simple fish taco sauce in a metal prep bowl and stir it up with my favorite cooking spoon.
  • These measuring cups make it easier to spoon the mayo and sour cream into.

How to make fish taco sauce

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

mixing fish taco sauce in a prep bowl

In a prep bowl, mix together all the sauce ingredients until smooth. Give it a taste, then adjust as needed. Chill in the fridge until needed to let the flavors intensify.

Helpful tips

  • As always, taste and adjust as you go along. You may want more of a certain ingredient, e.g. more lime juice or garlic powder.
  • This sauce gets better when the flavors have had a chance to meld, so making it ahead is always a good idea.

Substitutions and variations

  • You can make it without the smoked paprika if you prefer, but I think it gives the sauce a special little something-something.
  • Try stirring in some fresh chopped cilantro for a burst of freshness and a pop of color.

What to serve with fish taco sauce

  • Fish tacos, of course! This sauce is delicious on other tacos too, though. Try my Super Easy Ground Beef Tacos.
  • Or if you’ve cooked a piece of salmon or another type of fish without any sauce, this would go perfectly.

Leftovers and storage

  • This sauce will keep in the fridge in a covered container for up to 5 days.
  • I don’t recommend freezing this one.

Fish Taco Sauce

This easy homemade fish taco sauce recipe is the best version ever! It has a special ingredient to set it apart from other ones you've tried for a delicious taco night.
Prep: 10 minutes
Total: 10 minutes
Servings: 12 see note


  • 1/2 cup mayo
  • 1/3 cup sour cream
  • 2 tablespoons lime juice
  • 1 tablespoon sriracha sauce
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 1/4 teaspoon salt


  • Add the sauce ingredients to a medium bowl and stir together until smooth. Taste and adjust if needed (e.g. add more lime juice, sriracha, or salt). Refrigerate until needed. The flavors will meld the longer it sits. The sauce will keep for 5 days in the fridge in a covered container.


  • This sauce makes enough for about 12 tacos, but it really depends on how much sauce you put on each taco. It makes about a cup in total and will easily feed 4 adults. 
  • As written, this sauce isn’t particularly spicy, even with the sriracha. You can always add more than suggested to kick it up a notch.
