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.

  • Simply the best! We left out the cumin (not a fan) but followed the rest exactly. – so yummy! Quick, easy and delish. Thank you this is a new family favorite.

    • Hi Karen! Woo hoo!! So glad you enjoyed the tacos and thank you SO MUCH for letting us know and for the wonderful review! We appreciate that very, very much!! All the best, Kris & Wesley

  • My husband said these were the best fish tacos ever! I was out of smoked paprika, so I used hot paprika. It did add a lot of heat, oops! But my husband told me to not change a thing next time we make them. I also marinated some shrimp and they were fantastic. Thanks, so much, for your recipes and I really love your videos!

    • Hi Kim! Please forgive our late response! That is so so so awesome and we are thrilled that you and your hubby love the mahi mahi tacos! A little extra heat sometimes works out to be just the right amount of heat! Again, so glad you had such success with the recipe (and yum! shrimp, too!). And thank you so much for letting us know and for the great review!

  • My husband is the chef in the family, but after I made these tacos, even he was asking for more! Super easy and delicious!

  • I am a fried fish taco guy but was looking to change it up a little bit and hopefully in a healthier way. I came across this recipe and I loved it!! This will be my new go to fish taco recipe! For a second I thought about skipping the avocado line slaw, don’t do it! It really is worth the short time to make! I did cook this inside as I don’t yet have the pan for the grill, my advice to anyone who is going to do the same, get some fans ready. It starts smoking up pretty quick and I did set off a few smoke detectors. Totally worth it though! Thanks for the great recipe!!

  • Must say we absolutely loved these! Served them with a watermelon basil salad. Thanks for sharing the recipe.

    • Hi Cindy! Woo hoo!! We are so happy you loved the mahi mahi tacos! And wow! Alongside a watermelon basil salad sounds heavenly!! Thanks so much for letting us know and for the awesome review! That means the world to us!! All the very best, Kris & Wesley

  • 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.

And thank you so much for letting us know and for the FANTASTIC review! That means the world to us!! All the best, Kris & Wesley

  • 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
