Grilled Mahi Mahi with Blackened Seasoning
Coated with a blackened seasoning and grilled to perfection, this Grilled Mahi Mahi is an amazingly delicious piece of fish that is simple, satisfying, and ready in under 30 minutes!
Grilled Mahi Mahi
Mahi Mahi (also known as common dolphinfish or dorado) is a very mild white-fleshed tropical fish. It has a great, firm texture that makes it perfect for grilling.
Due to its mild flavor, it lends itself well to some good seasoning with lots of flavor. The blackened seasoning is a great compliment to the flavor of the fish, giving it a smoky, spicy punch.
Grilled Mahi Mahi Seasoning
This mahi mahi is seasoned with my awesome Blackened Seasoning. It’s a Cajun-style seasoning with salt pepper, smoked paprika, cayenne, and herbs. Check out the linked post for more info on this awesome seasoning.
Blackened seasoning goes great with mahi mahi. It’s not too sweet or overpowering. It’ll enhance the flavor of the mahi mahi while giving it a robust flavor with some decent heat.
How to Grill Mahi Mahi
Alright, let’s get to the process on grilling mahi mahi. It’s extremely easy to grill fish, and mahi mahi is no exception. Simply season, grill, and serve.
- Season. Brush the mahi mahi filets with melted butter and season them on all sides with the Blackened Seasoning.
- Grill. Preheat your grill to 425 degrees F. While the grill is preheating dip a paper towel in avocado oil (or another high heat oil) and place it between tongs. Brush the oil over the grill grates. Once the grill is preheated and oiled, place the seasoned mahi mahi directly on the grill grates and grill for 6 minutes per side or until the internal temperature of the fish reaches 145 degrees F.
- Serve. Remove the fish from the grill and serve immediately. This fish goes great with a side of rice and Grilled Broccoli. Make sure to serve with lime wedges, and you’ve got a fantastic meal on your hands.

How Long to Grill Mahi Mahi
It takes approximately 10-15 minutes to grill mahi mahi. For this recipe (using 6-ounch mahi mahi filets), it took around 6 minutes per side to grill the fish.
I highly recommend monitoring the temperature of the mahi mahi while it is on the grill. Always grill your meat and seafood to temperature and not to time, using time as a guideline only. Investing in a good internal meat thermometer (my favorites are the ThermoPop or Thermapen Mk4 from ThermoWorks). Once your fish reaches an internal temperature of 145 degrees F, you are good to remove the fish from the grill.
