Mahi Mahi Tacos with Slaw

Mahi Mahi Tacos go from prep to table in about 30 minutes. Seasoned fish is perfectly cooked then drizzled with a spicy sauce and topped with cilantro lime fish taco slaw.

Mahi mahi tacos are one of those meals that I could easily live off of, and it would never get old. I mention these tacos periodically in different posts, because they’re one of my absolute favorite seafood dishes, next to crab cakes and hot crab dip, and they remind me of the years my family lived in South Florida.

They’re easy to make and super versatile with a variety of topping options. Mahi mahi tacos make an easy lunch or dinner anytime, especially if you’d craving a meal with a bit of tropical flare! You can even use Grilled Mahi Mahi or baked Mahi Mahi instead of cooking the fish on the stovetop if you prefer.

How to make mahi mahi tacos:

  • Combine the garlic powder, onion powder, and seafood seasoning.
  • Pat the mahi mahi fillets dry with a paper towel, and sprinkle all sides with the seasoning mix.
  • Heat a medium skillet over low to medium heat. Add butter and oil, then add the fish.
  • Cook for 3 to 5 minutes on each side until an instant read thermometer reads 145°F when inserted into the thickest part of the fillets.
  • Allow the fillets to cool for 5 minutes before shredding into chunks with a fork. Place the pieces in tortillas, and add your favorite toppings.

What does mahi mahi taste like?

Mahi mahi is a warm water, white fish that’s commonly found in tropical and sub-tropical waters. It’s also known as dolphin (not the same as Flipper), dolphinfish, or dorado. It has a slightly sweet, mild flavor with hearty flesh. It flakes nicely when prepared properly and holds up well to other ingredients. Mahi mahi isn’t soft like cod or flounder. It has a meatier, steak-like texture similar to that of swordfish.

How do you keep mahi mahi from drying out?

If the fillets are purchased with the skin on, leave the skin on while they cook to retain some of the moisture.

Don’t overcook the fish; otherwise it will dry out quickly. Mahi mahi is considered safe to consume when it reaches 145°F. Much hotter than that, and it begins to dry out.

Try adding a lid to the skillet to hold in steam which will help lock in moisture.

  • Combine the garlic powder, onion powder, and seafood seasoning in a small bowl. Set aside.
