Mahi Mahi Tacos are absolutely…AMAZING!

These tacos are layered with flavor after flavor and really are out-of-this-world delicious. And what else is so amazing about these tacos?  They are on the table in about 30 minutes from start to finish!

MAHI MAHI TACOS ARE EASY TO MAKE AT HOME

Fish tacos may seem like something that’s not easy to achieve at home.

Trust us. These Mahi-Mahi Tacos are simple to prepare and are as good as you’ll get anywhere.  We love mahi-mahi because it’s not fishy tasting at all.  Learn more about mahi-mahi here.

Watch us show you how easy it is to prepare the Amazing Mahi-Mahi Tacos!

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 ” target=”_blank” rel=”noopener noreferrer nofollow sponsored”>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!

Amazing Mahi Mahi Tacos

These Mahi Mahi Tacos are now a staple in our house. So flavorful and easy to make. You can grill them, sear them, or bake them. The avocado-lime slaw is sublime. And the chipotle-aioli gives a wonderful kick. Incredible flavor!!

Equipment

  • Gas, Charcoal, or Electric Grill. Or a stovetop grill pan.

Ingredients

FOR THE AVOCADO-LIME SLAW

  • ½ cup mayonnaise
  • 1 avocado
  • ½ cup cilantro roughly chopped
  • 2 garlic cloves
  • 3 tablespoon lime juice
  • 4 tablespoon jalapeños pickled, chopped. Or 1 fresh jalapeno: cored and seeded
  • ½ teaspoon Kosher salt
  • ¼ teaspoon freshly ground black pepper
  • 12 oz. slaw mix

FOR THE CHIPOTLE AIOLI

  • ½ cup mayonnaise
  • 2 cloves garlic minced
  • 1 teaspoon lime juice
  • ½ teaspoon chipotle chile powder add more for increased heat, or regular chil powder for less heat
  • 1 pinch Kosher salt and freshly ground black pepper

FOR THE MAHI MAHI

  • 1 ¼ lb mahi mahi fillets skinless, cut into 12 pieces (can aslo use also use fresh tuna steak)
  • 4 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon Kosher salt
  • 2 tablespoon lime juice
  • 3 tablespoon olive oil
  • ½ teaspoon freshly ground black pepper
  • 12 corn tortillas
  • ½ cup fresh cilantro for garnish
  • ½ cup thinly sliced radish for garnish
  • 2 fresh jalapenos thinly sliced, for garnish
  • Hot sauce such as Tobasco, for garnish

Instructions

MAKE THE AVOCADO-LIME SLAW

  • In a food processor, add the mayo, avocado, cilantro, garlic, lime juice, jalapenos, salt and pepper and pulse until completely blended.
  • Add the mayo-avocado mixture to the slaw and stir until fully coated. Set aside.

MAKE THE CHIPOTLE AIOLI

  • Stir together the mayo, garlic, lime juice, chili powder, salt and pepper. Set aside.

PREPARE THE MAHI MAHI

  • Make the marinade by mixing together in a medium bowl the chili powder, cumin, paprika, onion and garlic powders, salt, pepper, lime juice, and olive oil.
  • Add the mahi mahi and turn to coat. Let rest for 15 minutes.
  • Meanwhile, heat your grill to high heat.
  • Place fish in a grill pan or cast iron skillet. Or, thread each fish piece with a skewer. Discard the left-over marinade.
  • Grill the fish, carefully turning once, until opaque and just cooked through, about 8 minutes total.
  • Heat the tortillas directly on the grill rack, or place in aluminum foil, and heat on the grill.
  • Place the cooked fish in the warmed tortilla and top with slaw, fresh cilantro, radishes, chipotle aioli, sliced jalapenos, and hot sauce.

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.

    Amazing! Although I don’t recommend doing blackened mahi mahi in your kitchen when your fan isn’t that good. But even smoking out the house is worth it for these tacos. They are on the repeat list. Thank you!

    I made these tacos for my family tonight. I didn’t grill but roasted in oven on 400 convection then put under the broiler to get edges brown and crispy. The tacos were phenomenal!!! I made everything as stated in the recipe except added some chipotle in adobo to the sauce for more spice. Thank you for this recipe!!

        Hi there! You can absolutely make the slaw ahead of time. For super fresh, maybe don’t mix the dressing in with the slaw just before folks arrive. Or, leave a little extra slaw on hand, and then stir some in just before serving. Hope this helps and have a WONDERFUL dinner party and please let us know how everything turns out!! Best, Kris & Wesley

    These tacos were amazing! The combination of the spicy grilled mahi mahi and the crunch and freshness of the slaw was oh so mouthwatering on an unusually warm January in California. I will definitely be making these again. Can’t wait to make them for friends and family when they are able to come over.

    We love love love fish tacos wherever we go. This is the first recipe I’ve ever found that can match a restaurant by the sea. So many recipes overpower the fish with spice. This recipe balances so we’ll with the mahi. Thank you for such a great recipe!

    WOW! This is absolutely delicious. On my second run I tried a new approach. Used whole Mahi in floor, then in marinade (instead of egg wash), then in a corn meal / panko mixture. Quick fry at about 350 then on to sliders with slaw and aioli. Great work guys!

    These were so good! And my 12 year old loved the coleslaw too! Made a mango and avocado salsa (w lime, cilantro and onion) and served the tacos with yellow rice and roasted sweet potato wedges – which were great with the aioli. Definitely a keeper! Thanks!!

    We are kind of snobs when it c1omes to fish tacos. These were amazing!!! I started with 3 pounds of fish and 2 pounds of raw shrimp (I have 7 kids).We ran out before my sister and her husband got to the house, so I quickly made 2 more pounds of shrimp and three more pounds of fish. Not a drop was left. Truly outstanding!!!
