What Are Mahi Mahi Tacos Made Of?
You need just a few basic ingredients to make the best mahi mahi tacos! Here’s what you’ll need:
- Spices: We’re seasoning our mahi mahi with a blend of garlic powder, onion powder, and seafood seasoning.
- Mahi Mahi Fillets: You’ll need fresh fish fillets from your local grocery store. You can also use frozen, but will need to thaw them first.
- Butter and Oil: I recommend a combination of unsalted butter and olive oil for cooking the fish. It adds delicious flavor and creates the perfect texture.
- For Serving: I love to serve these tacos on warm corn tortillas topped with fish taco slaw and fish taco sauce, then garnished with lemon or lime wedges.

These fish tacos are the perfect light and easy lunch or dinner! Just 10 minutes to prepare and 10 minutes to cook.
Scroll to the recipe card below for the full instructions and ingredient amounts.
- In a small bowl, combine garlic powder, onion powder, and seafood seasoning. Use a paper towel to pat the fish fillets dry, then sprinkle each side of the fish with the seasoning mix. Press gently to make sure it sticks.
- Add butter and oil in a medium skillet on the stove top, then heat over low-medium heat. Add the mahi-mahi fillets into the hot pan and cook until the internal temperature is 145ºF.
Tips and Notes
- Press the seasonings into the fish. This helps ensure that the spice rub sticks to the exterior.
- Don’t over-cook! With a leaner meat like mahi mahi, it can over-cook quickly. Keep in mind that thicker fillets will take longer to cook while thinner fillets will cook more quickly.
- Check the internal temperature. For the best results, use a meat thermometer to check the internal temperature of the fish. It should be 145ºF.
- You’ll know the fish is done when the texture is flaky and the meat is opaque.
- Spice things up. If you like some extra heat, try adding a little bit of chili powder or cayenne pepper to your spice rub.
Serving Suggestions
I love to serve these fish tacos with slaw and taco sauce.
If you want to switch things up, feel free to enjoy your tacos with hard taco shells or flour tortillas instead. They’re also delicious topped with mango salsa, pineapple salsa, red onion, Mexican taco slaw, pico de gallo, cilantro lime crema, or any of your favorite taco toppings!

Should I Soak Mahi Mahi Before Cooking?
Nope! There’s no need. Soaking fish before cooking it is usually to remove any muddy, fishy taste that it may have. Mahi mahi has a super mild flavor, so the extra step really isn’t necessary.
Is Mahi Mahi a Tough Fish?
No. Mahi mahi has a firm texture, but it definitely isn’t tough. When cooked properly it takes on a deliciously flaky texture, but still holds its shape well.
Keep in mind that over-cooking can cause the fish to come out tough and dry. Take it off the heat as soon as it reaches a temperature of 145ºF!
Storage
Leftover mahi mahi can be stored in an airtight container in the fridge for 3-4 days or in the freezer for 2-3 months.
To enjoy again, thaw overnight in the fridge if frozen, then warm in a baking dish covered with foil in the oven set to 275ºF.
