Steps To Make Blackened Mahi-Mahi Tacos with a Chipotle Mayo

These tacos come together so easily you might even end up adding them to your weekly rotation. Here’s how to get them just right:

Prepare the Chipotle Mayo
First things first, blend up your mayo, chipotle pepper, and lime juice until it’s smooth and creamy. You can taste it to see if it needs a pinch of salt, but honestly, the flavors here are pretty hard to mess up. This is where you can adjust the heat, too—more chipotle if you’re feeling bold. Pop it in the fridge to chill while you make the rest. It’ll thicken up a bit and get even better.
Mix the Blackening Seasoning
In a small bowl, combine the paprika, Italian seasoning, cayenne, garlic, onion powder, and black pepper. It’s a little smoky, a little spicy, and full of flavor. You’re going to love it. This part’s easy to overlook, but it’s worth taking the time to get this seasoning just right—it’ll make that fish sing.
Prepare the Mahi-Mahi
Cut your mahi-mahi into even pieces, then sprinkle each piece with that gorgeous seasoning blend. Make sure they’re evenly coated—it’s the seasoning that really gives it that “blackened” effect when cooked. Give it a few minutes to let the seasoning settle before it hits the skillet.
Cook the Mahi-Mahi
Heat a skillet on medium-high, add some cooking spray, and add your mahi-mahi. It doesn’t take long, so stay close by. Just a few minutes per side until the fish is beautifully browned and flakes easily. This part can go from perfect to overcooked fast, so keep an eye on it! Once done, set it aside for a minute to cool slightly.
Warm the Tortillas
For the tortillas, you’ve got options. Either warm them in a dry skillet for about 30 seconds per side or go the microwave route, with a damp paper towel to keep them soft. I usually go with the skillet, but honestly, either way works just fine.
Assemble the Tacos
Now, here’s the fun part: lay down some pieces of mahi-mahi on each tortilla, then sprinkle on some shredded cheese, cabbage, tomatoes, and cilantro. Drizzle a bit of that chipotle mayo over the top, and there you have it—tacos that are almost too good to share.

Storage Options:

Got leftovers? Lucky you! Just store any leftover mahi-mahi in an airtight container in the fridge for up to two days. The chipotle mayo is good for about a week in the fridge, so keep that handy for more tacos (or whatever else you want to slather it on). For best results, store the tortillas and toppings separately so things don’t get soggy. Then, just reheat and assemble when you’re ready for round two.

Variations and Substitutions:

These tacos are already pretty customizable, but here are a few ideas to make them your own:

Make it Spicier: Love the heat? Throw in an extra chipotle pepper or some sliced jalapeños. It’ll definitely wake up your taste buds.
Switch the Fish: If you can’t find mahi-mahi, don’t sweat it. Cod, snapper, or tilapia work great too. Just look for a firm fish that’ll hold up to the blackening.
Go Low-Carb: Swap the tortillas for lettuce wraps for a lighter, low-carb option that’s still totally satisfying.
Cheese Substitute: Monterey Jack is classic here, but crumbled cotija cheese is a great option if you want something with a little more tang.
Add Some Avocado: If you’re an avocado fan, a few slices on top add a creamy richness that really plays well with the chipotle and the blackened fish.

These tacos are delicious as-is, but don’t be afraid to get creative with them! You’ll have your own signature version before you know it.
