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.

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

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.

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.

    Oh my goodness! I cannot believe how delicious these tacos were. My advice to anyone who makes this is to double up on the avocado slaw. Don’t get me wrong, the mahi mahi was fantastic, but that slaw just became a staple in my kitchen. Thanks so much for this recipe!

    Joining in a few years after publication but made this tonight and absolutely LOVED it. I have a husband who is very opinionated about Mexican food, and he requested that I put this into regular rotation. In addition to the chipotle sauce and slaw, I also made a mango salsa which added another dimension. Love, love, love this – thanks!

    Great recipe! However, I am curious as to how the Chipotle Aoili is technically Chipotle, when there isn’t any Chipotle seasoning. Only chili powder. Also just trying to help, but there is a few typos. That doesn’t matter though! Thank you very much for sharing! (:

    • FOR THE CHIPOTLE AIOLI
      ▢1/2 cup mayonnaise
      ▢2 cloves garlic minced
      ▢1 tsp lime juice
      ▢1/2 tsp chipotle chile powder add more for increased heat, or regular chil powder for less heat
      ▢1 pinch Kosher salt and freshly ground black pepper

    • it’s right there in the recipe, it calls for chipotle chile powder, or it says for less heat to use regular chile powder
