This simple yet intensely delicious fish dish is all that and more.

What is rockfish
Pacific rockfish—also known as rock cod or Pacific snapper is a versatile lean white fish with a delicate flavor profile. It's a common near-shore fish found in the waters along North America's west coast. There are many different types of rockfish and they can vary in shape and size but what they have in common is their firm texture and mild flavor. Cooking rockfish is easy and quick, and because it's so adaptable, it makes a great choice for using in recipes where a fish type isn't specified.
How to make rockfish tacos
It's easy to make rockfish tacos in just a few simple steps:
- Make the tartar sauce. In a small bowl, mix some tartar sauce, lime juice, and cilantro.
- Prepare the rockfish. Pat the fish dry with paper towels and then season it on both sides.
- Cook the fish. Heat some oil and butter in a pan and sear it until it's deeply colored then break it into several smaller pieces.
- Make the slaw. Mix shredded cabbage with some of the cilantro lime tartar sauce.
- Assemble the tacos. Pile some slaw into a tortilla, top it with a few rockfish pieces and any other toppings, then drizzle the top with a spoonful of cilantro lime tartar sauce.

Ingredients you'll need to make these fish tacos
You'll need just three ingredients for the cilantro lime tartar sauce:
- Tartar sauce – a store-bought version works perfectly as a base for the sauce.
- Cilantro – adds its unique fresh flavor.
- Lime juice – adds tang and brightens it up.
Here's what you'll need to make the rockfish tacos:
- 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.
- Oil – any neutral cooking oil.
- Butter – adds a rich flavor to the fish and helps prevent it from sticking to the pan.
- Cabbage – for that wonderful crunch.
- Tortillas – you can use your favorite kind, flour or corn work great.
- Toppings – minced red onion, avocado slices, and lime wedges are what we used in the pictures, but you can have fun and add your favorites. Our easy guacamole recipe goes really well with these tacos!
Rockfish Tacos: Frequently Asked questions
Yes! Any type of firm white fish like lingcod, red snapper, or tilapia works well. Or go for a richer flavor and try salmon.
Either corn or flour tortillas work great. We like using small, 4-inch soft tortillas, but larger ones work, too.
The fish will taste best when it's freshly cooked. However, leftovers will stay fresh in the fridge for up to 3 days.
