Grilled Mahi Mahi Tacos

If you’ve read Favorite Family Recipes for any length of time, you know that we loved our fish tacos around here. We simply can’t get enough of them! We probably have enough fish taco recipes to have a different one every day of the summer. And believe me, I wouldn’t complain! These Mahi Mahi tacos are made with the freshest ingredients and powerful flavors. My family loves them, especially because they can dress up their tacos any way they like. We love grilling the fish on an outdoor grill, then serving our tacos alongside glasses of icy cold lemonade out on the patio. This really is the perfect summertime supper.

Best Fish to Use for Fish Tacos

Mahi Mahi is a mild, flaky fish that is delicious to start with if you’re just getting familiar with fish tacos. Most grocery stores will carry mahi-mahi fillets. You can also use halibut or cod, which are more white fish than mahi mahi, which has a pinkish color. But both are great substitutes for mahi mahi fish tacos. Snapper or tilapia are also great options and are all packed with protein, fiber and potassium. So healthy and so delicious!

Where to Find the Best Mahi Mahi Fillets

  • The biggest trick to perfect fish tacos is fresh fish! Get the freshest you possibly can. Fish markets have delicious options or even the fish counter in your grocery store.
  • If you can’t find fresh fish, go frozen! The ones at the grocery store that are packaged up and look fresh, probably aren’t. They have probably been frozen before. Ask the people in your meat department if they had been previously frozen. If they have, ask for filets that are STILL frozen and then go home and keep them frozen until you are ready to thaw them.
  • You can also find frozen filets at Costco or Sam’s Club that are really tasty! Find them in the freezer section. Generally they’re frozen individually so they stay nice and fresh.

How to Prepare Mahi Mahi for Fish Tacos

  • We almost always go the grilling route when preparing meat for fish tacos. The fish takes on a smoky flavor that is just mouthwatering! 
  • You could grill it on an indoor grill too, or broil in the oven. Just make sure to use a good cooking spray or cover your pan in foil to avoid sticking.
  • Seasoned fish is really easy to make your own. Try adding jalapeno, different garlic powders, chili powder, paprika, cayenne pepper, black pepper, or onion powder  to your fish filets. Using these spices instead of salt cuts down on sodium and gives the fish bright, vibrant flavors.

Other Ingredients in Mahi Mahi Fish Tacos

  • The beauty of fish tacos is how versatile they are. We set up a long buffet of toppings so everyone can dress their dish up any way they like. We love a shredded cabbage slaw, salsa, sour cream, grilled corn, cilantro, avocado, onion, feta cheese, hot sauce, and pico de gallo.
  • Add mango salsa, wedges of sliced mangoes, or coleslaw to your tacos.
  • Serve with corn tortillas, or flour tortillas. If you prefer a crunchy shell, by all means, pile your ingredients into a hard corn taco shell. 
  • Garnish with a lime wedge and a sprinkle of cilantro.
