How to make Blackened Mahi Mahi
The Ingredients
Mahi Mahi Fillets: Mahi Mahi is a firm fish with a mild taste and a meaty texture, making it the perfect choice for this dish.

The Directions
The blackening spice blend. Mix the paprika, cayenne pepper, garlic powder, onion powder, dried thyme, oregano, salt, and black pepper in a small bowl. This spice blend will give the mahi mahi its delicious flavor. Adjust the amount of cayenne pepper if you prefer more or less spice.
Prepare the mahi mahi fillets. Remove excess moisture, but pat dry with a paper towel. This helps the spices absorb better.
Coat the mahi mahi with the spice blend. Rub the blackening spice blend onto both sides of the fish fillets and evenly coat them. This will give the fish a tasty and flavorful crust when cooked.
Cook the mahi mahi. Over medium-high heat, place a large skillet and add olive oil. Once the oil is hot, carefully place the spice-coated mahi mahi fillets into the skillet.
Cook each side for 4-5 minutes or until the fish blackens and easily flakes apart with a fork.
Serve and garnish. Transfer blackened Mahi Mahi to a serving platter. Drizzle fresh lemon juice and sprinkle chopped fresh parsley on top for the flavor.
What to Serve with Blackened Mahi Mahi
Rice: Choose from white, brown, or flavored varieties like lemon-cilantro rice. The fluffy texture and mild taste of rice will nicely balance the bold flavors of the blackened fish.
Potatoes: Roasted, mashed, or spicy, potatoes are comforting. Special mention goes out to these spicy roasted sweet potatoes, Cumin potatoes.
Mango salsa: The fresh and fruity taste of mango salsa(or this spicy mango sauce) pairs beautifully with blackened mahi mahi.
Fresh salads: Choose from options like Greek salad or heirloom tomato salad.
Green beans or steamed broccoli: These simple sides provide an excellent, mild taste to accompany the blackened Mahi Mahi.
Cole slaw: Creamy, tangy, and slightly sweet, Cole slaw is a refreshing side dish that complements the spiciness of blackened mahi mahi(see our Cajun coleslaw or jalapeno coleslaw for inspiration).
