MAHI MAHI TACOS ARE LAYERED WITH FLAVOR

Before we get to the star ingredient of these mahi-mahi tacos, let’s talk about what else makes them so great.

The Avocado Lime Slaw is incredibly fresh and bursting with flavor.

It’s wonderful because the recipe gives you plenty to put on your tacos, and then have lots leftover as a side dish. Yum!

Another delicious addition to these mahi-mahi tacos is a zesty chipotle aioli.

EXPERT TIP: The chipotle chili powder adds heat, so if you want to go super mild, you can use just regular chili powder.

The fresh garlic and lime juice round out the flavor profile of the aioli perfectly.

BLACKENED MAHI MAHI CAN BE GRILLED OR SEARED IN A SKILLET

Mahi Mahi is a great fish to blacken and then either grill or sear in a hot skillet.

EXPERT TIP: If grilling, a grill pan is great for keeping the fish from falling through the grates.  Or, you can run skewers through the fish pieces.

The fish only need to cook for a total of 5 to 8 minutes to become cooked through and starting to flake. And the smell?  Crazy good.

Finally, we love to double-stack each taco with two corn tortillas.

To bring out the amazing corn taste, even more, we either throw the tortillas on the hot grill for a few minutes or place them directly on the stove gas flame.

All you need is a few flips of the tortillas and they are good to go. You could also do this by placing them individually on a skillet. Just keep them in a pocket of foil to keep them warm as you heat them all up.

THEY COME TOGETHER QUICKLY

And it just keeps getting better, these tacos only take about 30 minutes from start to finish!  We love to serve them 3 per serving on our taco holder stand!

The combination of the blackened mahi-mahi, the avocado-lime slaw, the kick of the chipotle mayo and all the fixins is out of this world.

These mahi-mahi tacos have become one of our favorite go-to tacos recipes. Once you try them, you’ll most likely feel the same way!

Notes

Use your favorite type of chili powder.  We like chipotle chili powder, but this will definitely add some heat.  If you're looking for low to no spicy heat, then use regular chili powder.  
If you can't find mahi-mahi, you can use quality tuna steak, or swordfish, or cod.  
We highly recommend placing the marinating fish into a grill pan, or a cast iron skillet before grilling.  Alternatively, you could can thread the fish pieces onto skewers.
If warming the tortillas on the grill, don't leave them on too long, otherwise the heat will dry them out.  You can place them in a foil packet and warm them that way.  You won't get the nice charred grill marks, but they won't dry out that way.

  • AWESOME !!!!!!!! We caught 8 Mahi on Saturday just of of Key Biscayne and kept them on ice until Sunday when we cleaned them. I made a different recipe for Sunday dinner and was going to prepare either tacos or sandwiches today for dinner. I wish I had of made these for Sunday dinner. My 11 year old son wanted fish tacos today and fortunately, I found this recipe. A few more kids are sleeping over tonight (within our pandemic bubble) and all 5 kids and my wife loved them – she wants me to open a food truck and only sell these. Everyone had enough except me – I had to settle for only the cook’s tastings while preparing, but I’m going to buy some Mahi tomorrow prepare for lunch. GREAT RECIPE – THANK YOU!!!
