Sprinkle the blackened seasoning and salt, if seasoning does not already include it, over the filets and rub it into the fish.

Melt butter in a cast-iron skillet over medium-high heat. Wait for at least 1 minute so butter is heated through. Add the mahi mahi to the skillet, skin side-up, and cook for 4-5 minutes. Flip the filets over and continue cooking for 3-4 more minutes or until cooked through.

Notes
Blackened Seasoning: The Evolving Table Cajun Blackened Seasoning spice blend was used when testing this recipe. If you opt for another brand (like Slap Ya' Mama or Tony's) you'll need to adjust the amount of salt and seasoning you add depending on your desired spice level.
Crispy sear: A cast-iron skillet is essential to get that classic, crusty char on the blackened fish.
