An easy, elevated fish dinner that’s easy enough for a weeknight, but feels like a fancy, dine-out meal! This blackened Mahi Mahi is coated in a homemade Cajun blackened seasoning, and air fried to perfectly tender, buttery fish in no time. From start to finish you’ll have this delicious white fish on your table in under 15 minutes!
Make sure the fish is thawed thoroughly. Pat dry with paper towels. Rub the spice mixture all over each fillet, coating it completely and pressing down with your fingers to make it stick.
Stove Top / Skillet
Heat the butter and oil in a large cast iron skillet. When sizzling hot, add the mahi mahi. Cook for 3-4 minutes without touching, then carefully flip and cook for another 3 minutes. The fish should flake easily at that point.
Let it rest for a couple of minutes, then serve with a squeeze of lemon on top. I like to serve this with some fruity salsa, potatoes, rice, or veggies!
Air Fryer Mahi Mahi
Preheat air fryer to 400 for 3 minutes.
Spray the basket with cooking oil, then add the fillets in an even layer (you may need to do this in batches).
Air fry for 8 minutes or until the fish flakes easily with a fork. Enjoy!
Notes
Expert Tips
If you want a spicier blackened seasoning, add more cayenne pepper. If you prefer a very mild spice, omit or decrease the cayenne pepper.
Serving Tips
Serve with your favorite sides and lemon wedges or slice and make fish tacos with corn tortillas and this homemade mango salsa.
Storage Tips
Store leftover air fryer Mahi Mahi in an airtight container in the refrigerator. Reheat in the air fryer or stovetop and serve with the salsa.
