About Blackened Fish Tacos

I'm really stoked to share this with you—these Blackened Fish Tacos are a total flavor explosion! We're talking flaky fish—that's been kissed by a spicy Cajun rub—resting in a warm tortilla. It's like a party in your mouth, seriously.
They're not difficult to whip up, either. I promise! We'll use a blend of spices that'll make your taste buds sing, and you can adjust the heat to your liking. Think of them as a quick weeknight dinner solution, or for when you want to impress your friends with your mad cooking skills! The use of fresh ingredients is key, enhancing the overall flavorful nature.
The best part? You can throw the slaw together fast, while the fish is cooking on the pan, talk about being efficient! And I always toast my tortillas, it's worth doing. Now, let's delve into what makes these tacos so incredibly tasty!
Key Ingredients

Okay, let's explore into what makes these tacos rock, starting with all the key ingredients! I'm talking about fresh tilapia fillets–they're gonna soak up all that spicy goodness.
Next, we've gotta have the spice blend. Think paprika, cumin, onion powder, garlic powder, thyme, dry mustard, salt, and a pinch of cayenne pepper for some kick! Don't be shy–it is the heart of the 'blackened' flavor. You can get ideas for adding a glaze like teriyaki to your fish from Asian cuisine.
Now, the slaw! You will need Greek yogurt, avocado, cilantro, garlic, lime juice and zest, jalapeños, mint, red and green cabbage, carrots, salt, and pepper creating a creamy, zesty, crunchy counterpoint to the fish.
And let's not forget the Sriracha aioli! A simple blend of mayonnaise, Sriracha, and lime juice is a must!
Steps to Perfection

With our ingredients prepped and ready, let's get cooking. First, I'm showing you how to make the slaw. Basically, we're tossing shredded cabbage and carrots with that creamy avocado-lime dressing, and don't be shy with it!
Now, it's time to kick up the heat with the fish! I like to dredge each fillet in a mix of spices; that's where the magic happens. A hot pan and a little patience will give them a perfect blackened crust. I usually cook them about 2-3 minutes per side!
Here's a quick rundown:
- Blend the slaw dressing and refrigerate.
- Mix sriracha aioli until it blends into a creamy delight and refrigerate.
- Combine spices and coat each fillet evenly on both sides.
- Cook in batches in a hot pan until perfectly blackened; you should slice them into pieces.
Cooking these tacos is simple and fun!
Serving Suggestions

Now that we've got all the components ready, let's assemble these bad boys!
I usually pile the blackened fish onto those warm tortillas first. Don't be shy—we're talking about flavor explosions, so let's not skimp!
Next, spoon on a generous heap of that creamy avocado-lime slaw. I love how it balances the spice.
If you're feeling brave—and I always am—add a few slices of jalapeños! We want that extra zing if you can handle the heat.
Finally, a drizzle—or maybe a generous pour—of the Sriracha aioli. I'm telling you, it's the secret ingredient! Serve immediately; you don't want your tacos getting soggy! A fresh lime wedge is also great to squeeze on top for some added tartness. Enjoy your culinary masterpiece!
Recipe Notes

Before you investigate into the eating, let's talk about some extra tricks to make this recipe even better. I've got a few ideas to make your taco night a roaring success!
Here are some of my favorites:
- Slaw Shortcut: If you want to keep things quick and simple for the filling, just grab a bag of pre-shredded cabbage.
- Tortilla Tip: Heating tortillas makes them stronger, and it'll save you from the double-tortilla drama – especially with corn ones!
- Spice it Up: Adjust the amount of cayenne pepper in the spice blend to match your heat preference.
- Make Ahead: Save time by prepping components ahead of time. The slaw and Sriracha aioli can be made a day in advance.
I always say – a little prep makes for a delicious party!
