Blackened Rockfish Tacos with Cilantro Lime Tartar Sauce
This post may contain affiliate links. Please read our disclosure policy.
Pacific rockfish is the star of the show in these rockfish tacos with cilantro lime tartar sauce. The fish is perfectly seasoned and blackened, then the juicy chunks are tucked into warm tortillas with crunchy cabbage slaw and drizzled with a tangy tartar sauce. They’re a quick, delicious, and light dinner that’s ready in 20 minutes!
When it comes to tacos, I’m always looking for that perfect balance: something hearty, something crunchy, and something creamy. These rockfish tacos nail it with flaky white fish seared in blackening spice, a crisp cabbage slaw, and a generous drizzle of cilantro lime tartar sauce, finished with plenty of fresh cilantro and lime. They’re simple, bright, and packed with flavor—exactly the kind of light, satisfying dinner I love making on busy nights. Best of all, they’re on the table in about 20 minutes, which makes them an easy choice for the weekly rotation.
For the fish, I use rockfish because it cooks quickly and has a mild, delicate flavor that lets the toppings shine. It’s a lean white fish with a firm texture, which means it holds together beautifully in tacos and works well with bold, fresh flavors.
Key ingredients you’ll need
- Rockfish – has a juicy, delicate flavor. You can substitute another white fish like tilapia or snapper.
- Blackening spice – if you don’t have blackening spice, cajun seasoning makes a great (and spicy!) substitute. Or taco seasoning and fajita seasoning also work well and only have a little heat.
- Cabbage – for that wonderful crunch.
- Plus some tartar, cilantro, and lime juice for the sauce!
Sides for serving
These tacos are a meal on their own, but we love serving them with a side of crispy tortilla chips and some easy guacamole, chipotle guacamole dip, or corn salsa.
To make it a heartier meal, or for serving to a crowd, try them with our spicy Mexican rice or loaded food truck Mexican nacho fries.

Amazing and easy to make! I bought the rock fish from a sustainable fish market on a trip to the Oregon Coast. This recipe made this absolutely fresh fish taste even more amazing and I didn’t have to buy a lot of ingredients. My only mistake was too much blackened seasoning (I didn’t follow the recipe correctly), not realizing it was so spicy. But the coleslaw and tartar sauce recipe softened it to the taste.
These were such good tacos! We have never had rockfish before and we really enjoyed it. Thank you for such an easy, convenient, and delicious meal.
This was easy and tasty.
So simple to make, but incredibly flavorful! I had frozen rockfish and was perusing recipes when I found this. I wouldn’t change a thing!
