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

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 word! These were ¡ Muy Sabroso! I had cilantro and jalapeños from the garden. We warmed the tortillas on the grill for the first time-totally makes a difference. Marinade was perfect, aioli was superb, slaw was out of this world. Could only find frozen Mahi Mahi but it was still fantastic-and I’m usually not big on fish or aioli. Great job- our family loved this meal:)

    • Hi Laura!! So sorry for the delayed response. Woo hoo!! We are so so thrilled you loved everything about the mahi-mahi tacos.

    These are the best homemade fish tacos I’ve ever had and one of the best fish tacos I’ve ever had. I’m one those people that rarely leaves comments but these were so good, I was compelled to leave one because you simply must try these. Since I don’t have a grill I used my air fryer to cook the fish, 400° 12-14 minutes. It won’t fry it, (I wasn’t trying to) but it cooks it to perfection and you get flaky and moist fish. I added pico de gallo instead of the jalapeno slice- tomato, cilantro, jalapeno, onion, and some salt. Definitely making these again and again.

    • Hi Shei!!! Wow oh Wow! You have no idea how happy you just made us! We are so thrilled you loved the tacos and your modifications sound fantastic!! Thank you so much for letting us know and for the awesome review!! We appreciate that really so very much!! All the best, Kris & Wesley

    These are by far the best white fish tacos we’ve had. Super simple with tons of flavor! They are now a staple in our dinner rotation. In addition, we have taken to trying various tortillas–including (my favorite) the Jicama wraps from Trader Joe’s. Great recipe!

    This was great. We followed everything to a T. We may sub greek yogurt for mayo next time for the slaw to experiment…

    WOW! These are amazing! I usually take a recipe and make it my own but not with this recipe as they looked amazing and had great reviews. This is a keeper. I did double the blackening sauce and also made chicken for one of my kids and that was great too.

    • Yay!!! That is absolutely amazing to hear, Cheryl!! And kudos on pleasing the kids, too!!! Major win!! So glad you had success with the recipe and thank you SO MUCH for letting us know and the amazing review!! Means absolutely the world to us!! All the very best, Kris & Wesley

    • Hi Catherine! You can absolutely make the slaw and mayo ahead of time. The fish will be fine with the rub on it, but the texture of the fish might be compromised if you cook the fish a day ahead of time. Honestly, it would still be delicious, but we find the mahi mahi is best served right after cooking. But again, all the other components can definitely be made a day ahead, and are even better the next day! Let us know if you have any other questions and if you make them, let us know what you think!! All the best, Kris & Wesley

    Very, very good! So fresh! The avocado lime Cole slaw was fantastic! We’ll be making that Again even by itself.
