Ingredients for mahi mahi fish tacos.

What is Mahi Mahi?

Mahi Mahi is the Hawaiian name for dolphinfish or dorado. It’s a saltwater species that prefers warm waters. For this reason, it’s commonly found in the Caribbean, Mediterranean, and South Pacific. It’s also a lean, firm, and white meat fish that doesn’t have a strong fishy flavor. Mahi-mahi is perfect for marinating, grilling, and frying because it doesn’t fall apart easily.

Ingredients For Mahi Mahi Tacos

It’s all about simple ingredients for these tacos. Check out the recipe card at the bottom of the post for full ingredient amounts.

For the Fish

  • All-Purpose Flour
  • Cornstarch: Keeps the batter light.
  • Baking powder & Baking soda
  • Salt, Garlic powder, Dried oregano, Red pepper flakes
  • Water
  • Mahi Mahi fish fillets
  • Salt and pepper
  • Vegetable oil: Corn and canola oil will also work.

      To Assemble the Tacos

      • Corn tortillas: Don’t use flour tortillas for this.
      • Chipotle Mayo
      • Green cabbage: Purple cabbage is a great substitute and adds a nice pop of color. Feel free to use a combination of them.

      How to Make Mahi Mahi Fish Tacos

      For the Fish

      • Make the batter. Whisk the flour, cornstarch, baking powder, baking soda, salt, garlic powder, dried oregano, and red pepper flakes in a medium-sized bowl until well combined. Add half of the water and mix well. Add more water as needed to adjust the consistency. It should be slightly thicker than pancake batter. Set it aside.
      • Season the fish. Season the mahi mahi with salt and pepper to taste on all sides.
      • Prepare the oil. Pour the vegetable oil into a medium-sized pot over medium-high heat. Let it heat for about 4 minutes. Meanwhile, lower the mahi mahi pieces into the batter. Stir them around until they’re completely coated.
      • Fry them. Take one battered fish and dip the tip into the oil. If it sizzles right away, it’s ready. Gently lower a couple of battered mahi mahi pieces into the oil. Let them fry for 30 seconds on each side or up to 1 minute until golden brown. Remove them from the oil and set them on a paper towel-lined plate or cooling rack. Slice it in half and check for doneness. It should flake and be completely opaque on the inside. The thicker the fish, the longer the cooking time. Adjust the frying time as needed by increasing or decreasing it. You can also lower the heat as needed. Let the oil reheat for 30 seconds before frying the next batch.

      To Make the Tacos

      • Make the chipotle mayo. Whisk the mayonnaise and chipotle until you get a smooth mixture. Adjust the flavor to taste. Add more mayonnaise for a milder sauce, and more chipotle for a spicier one.
      • Heat the tortillas. Place the tortillas on a griddle or comal over medium-low heat. Let them heat on each side for 1-2 minutes or until warm. Remove them from the heat.
      • Serve. Place the tortillas on a serving plate. Additionally, place the fried fish, shredded cabbage, and shredded carrots on separate plates too. Let everyone assemble their own tacos with a tortilla, fish, and their favorite toppings. Add chipotle mayo and hot sauce to taste.

      Tips & Variation Ideas

      These tips and variations will help you make the best possible mahi mahi fish tacos.

      • Fish Selection. Tilapia and halibut are excellent substitutes if you’re out of mahi-mahi.
      • Use baking powder and soda. Although adding one or the other might be tempting, you must add both if you want the batter to fizz up. It’s the only way it’ll be nice and airy when frying.
      • Make chipotle coleslaw. Mixing the chipotle mayo with the cabbage and carrots can give you a 2-in-1 chipotle coleslaw topping.
      • Add more toppings. Pickled red onions, cilantro, and even diced mango are great toppings for more flavor.
      • Use breaded fish. You can use regular breaded fish when you don’t have enough time to make the batter and fry the fish.

      How to Store Extras

      Don’t store fully assembled mahi mahi fish tacos because they’ll soften too much. The tortilla will also break when you try to pick up the tacos after reheating. You want to store the taco elements separately if there are any extras.

      • Refrigerate the chipotle mayo in an airtight container for up to 7 days.
      • The shredded cabbage and carrots can be refrigerated for up to 5 days.
      • The fried fish can be refrigerated for up to 3 days.
      • None of the toppings need to be reheated, only the fish. You can microwave it for up to a minute or until warm. You can also heat it in a pan over medium heat for 2 to 3 minutes on each side. Assemble the tacos as usual.

      Notes

      • Fish: Mahi-Mahi is an excellent fish for tacos, but you can also use any lean and flaky white fish fillets like tilapia, halibut, snapper, etc… If you are pressed for time, you can use store-bought battered fish.
      • Coleslaw: Light and tangy coleslaw is a perfect partner to fish tacos, but you can also use pickled onions, jalapeno slices, mango, and whatever else you enjoy. 
      • Tortillas: Corn tortillas are the most authentic choice for fish tacos, but if you prefer flour tortillas, feel free to use those instead.
      • You can prepare the fish, the chipotle mayo, and the toppings in advance so that all you need to do is assemble the tacos when it’s time to eat.
      • Air Fryer Method: Line the air fryer basket with parchment paper (for easier cleanup)  and cook the fish at 390˚F for 15 minutes, turning them halfway through cooking. 
      • The fried fish can be refrigerated for up to 3 days.
