Want to SAVE this recipe?
How’s your summer going so far? We’re just coming out of a heat wave unlike anything we’ve seen in Montreal in recent years. Considering what a brutal winter we had though, I have ZERO complaints.
And the heat did not stop us from enjoying as many meals on the deck as possible. Especially light, flavorful meals that go nicely with a cold beer or this fresh squeezed lemonade recipe.
For me, this equals tacos!

Remember this Cajun blackened fish from last week? After I saw how easy and delicious it was, my head was spinning with ideas to put it in everything. I didn’t waste any time, and decided to start with these blackened fish tacos.
I whipped up a quick black bean and corn salsa, and with an easy lime crema and some crumbled queso to top it all off, this was the perfect outdoor summer meal!

Although I consider tacos to be a meal all on their own, if you’re trying to feed a crowd, some Cajun rice and/or a watermelon salad on the side are never unwelcome!
What is blackening?
Blackening is a cooking technique used in Cajun cooking whereby a protein (like fish, chicken, or shrimp) is dredged in butter, well-coated in a blend of spices and then cooked over high heat.
The result is a dark, flavorful crust on the outside and a moist interior.
In this case, I opted to skip the butter and just sear the fish in a little oil, and it worked perfectly. Feel free to coat the fish in melted butter first, if you’d like to go the traditional route!
Ingredient notes
Blackened fish

Firm white fish
Any firm white fish, including, haddock, halibut, cod, tilapia, snapper, grouper, mahi mahi or flounder can be used. I most often use rockfish or grouper (pictured above), depending on price and availability.
See below for more info on rockfish, which is my personal favorite when I can get it.
Spices
The spices in this blackened fish recipe are those of a typical Cajun seasoning and you probably have all of these on hand. Making my own Cajun seasoning is my preference for freshness and also because I can adjust the spices to taste.
Instead of this blend you can use 2 1/2 tablespoons of store bought Cajun or blackening seasoning if you like.
Canola Oil
Since blackening is done over high heat, you need an oil with a high smoke point. Good choices are canola or vegetable oil, avocado, grapeseed, or peanut oil.
Olive oil’s smoking point is too low for high heat cooking.
Corn and Black Bean Salsa
The salsa came together really quickly with canned black beans and frozen corn, some veggies, cilantro and a tangy lime vinaigrette. It was the perfect complement to the fish, but would also be terrific on it’s own, served with chips!

Black Beans
I love the color and small size of black beans in salsa, but feel free to sub any bean you have on hand. I use canned beans for simplicity but you can absolutely soak and cook your own.
Red Onion
Red onion is relatively mild, and great for salads and raw recipes. It also has great color. However feel free to use a white or yellow onion instead.
Cilantro
If you don’t like cilantro, parsley may be used instead.
For Serving
I love to make a simple lime crema to serve with these tacos, but you can use plain sour cream or crema instead.

Corn Tortillas
I love to lightly char and warm corn tortillas in a very hot cast iron skillet. They only take a few seconds per side each, and it gives them great texture and pliability.
You can definitely use flour tortillas instead of corn if you like.
Sour Cream
Crema, crème fraiche, yogurt or Greek yogurt may be substituted. I prefer a full-fat sour cream, but low-fat can be used too.
Queso fresco
I often use feta instead of queso fresco. Both are crumbly salty cheeses with a similar flavor. You can used shredded Monterey Jack or another shredded cheese if you prefer.
What is Rockfish?
I most often use rockfish , also known as Pacific snapper for blackened fish. It tastes great and is inexpensive.
I discovered it when my fish monger was out of my first choice, red snapper. It looked similar so I decided to give it a shot, and ended up liking it even better!
Rockfish is a bass-like fish, common in the pacific ocean. It has a firm white flesh and a mild taste. If you can’t find it though, you can of course substitute any firm white fish.
how to make blackened fish tacos step-by-step
- In a small bowl, combine spices (paprika, onion powder, thyme, oregano, cayenne, salt and pepper) to make an easy Cajun seasoning.
- Sprinkle the seasoning on both sides of the fish. Use all of it for the best blackened crust.


- Heat the oil in a cast iron pan over high heat and cook the fish until deeply charred and cooked through, about 2-3 minutes per side. Set aside and cover with foil. Tear into large chunks before serving.

- In a small bowl, whisk together the olive oil, vinegar, lime juice, garlic, salt and pepper.
- In a large bowl add the black beans, corn, tomatoes, onion, and cilantro.


- Add the dressing and toss to combine.

- Make the lime crema: combine sour cream, lime zest, lime juice, and salt in a small bowl.

8. Heat a cast iron skillet over high heat (no need for oil) and cook each tortilla for a couple of minutes per side to lightly char and heat.
9. Assemble the tacos with a few chunks of fish, a spoonful of corn and black bean salsa, a scoop of lime crema and a sprinkling of queso fresco and cilantro, Serve with lime wedges,

In my opinion these are the ultimate fish tacos. Full of fresh flavor, and much healthier than the battered and deep fried variety.

We CANNOT get enough tacos (or Mexican food in general) around here. If you love them as much as we do, here are a couple other tacos we love!
Ground beef tacos al pastor-style
And if you you just can’t wait longer than 15 minutes for your Mexican food fix, try these easy chicken quesadillas! (Now that I think of it, I think the corn and black bean salsa for these blackened fish tacos would be amazing in – or on top – of these quesadillas!).
Hope the weather’s treating you well and you’re getting in plenty of downtime with your friends and family!

This is a very adaptable recipe. We’re in the COVID-19 days, and I was limited in the produce arena. Subbed the onion and tomato for jarred salsa, no cilantro, bottled lime juice with no zest. Still amazing flavor! Oh, and I used tilapia. Thank you for a great meal!
I love that Tara! So glad you were able to make it work for you. 🙂
This was my first attempt at fish tacos and I am so glad I came across this recipe! I found rockfish at a cheap price and was looking on pinterest for a recipe for it. These tacos are fantastic. I love the fresh salsa and all of the flavors really compliment each other. I used the feta because I am not a fan of queso fresco and it paired perfectly with the tacos. Thank you so much!
Yay thank you so much for letting me know, Dawn! This one one of my favorite meals from last summer :). Rockfish was definitely a revelation for me. Way less expensive than cod or similar AND sustainable!
I loved this!! I am following Weight Watchers Freestyle, and this is a great recipe for the plan- corn, black beans, and lean fish are all 0 points! (I made some modifications).
I made the crema with 0% Fage Greek yogurt instead of sour cream (0 points) and it was still delicious!
I used Mahi mahi as the fish, and used a little less oil in the salsa and used cooking spray instead of oil for cooking. The queso fresco is awesome but depending what my daily budget looks like, these are still delicious without. The store didn’t have fresh cilantro but I used to Goya cilantro cooking base to season the salsa and it was good (fresh herbs are always better but this worked in a pinch!)
Awesome Debbie! LOVE how you adapted them to meet your dietary needs!
