Ingredients List

For the Blackening Spice Mix:

• 1 tablespoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1 teaspoon cayenne pepper (adjust to taste for heat preference)
• 1 teaspoon black pepper
• 1 teaspoon salt
• ½ teaspoon cumin

For the Fish:

• 4 mahi mahi fillets (6 oz each), approximately 1-inch thick

• 2 tablespoons high-heat oil (avocado or grapeseed)

Step-by-Step Instructions

Step 1: Prepare the Blackening Spice Mix

Combine all spice ingredients in a small bowl and mix thoroughly. The vibrant red color from the paprika and cayenne should be evenly distributed throughout the mixture. This can be prepared up to one month in advance and stored in an airtight container to intensify the flavors.

Step 2: Prepare the Mahi Mahi

Pat the mahi mahi fillets completely dry with paper towels. This crucial step ensures proper spice adhesion and helps achieve that signature blackened crust. If the fillets have skin, you can leave it on for cooking and easily remove it before serving.

Step 3: Season the Fish

Brush each fillet with melted butter, ensuring all surfaces are lightly coated. The butter acts as both a flavor enhancer and binding agent for the spices. Generously apply the blackening seasoning to all sides of the fish, pressing gently to create an even coating.

Step 4: Heat the Pan

Heat a cast-iron skillet over medium-high heat until very hot (about 2 minutes). Cast iron retains heat exceptionally well, creating the perfect cooking surface for blackening. Add the oil and swirl to coat the bottom of the pan. When the oil shimmers slightly, it’s ready for cooking.

Step 5: Cook the Fish

Carefully place the seasoned fillets in the hot skillet, allowing at least 1 inch between pieces to maintain proper heat distribution. Cook for 3-4 minutes without moving to develop the characteristic blackened crust. The spices will become aromatic and darkened (not burnt) as they cook.

Step 6: Flip and Finish

Gently flip each fillet and cook for an additional 3-4 minutes until the fish reaches an internal temperature of 137°F (58°C). The fish should be opaque throughout and flake easily with a fork. If using fillets of different thicknesses, adjust cooking time accordingly.

Step 7: Rest and Serve

Transfer the blackened mahi mahi to a clean plate and let rest for 1-2 minutes. This brief resting period allows the juices to redistribute throughout the fish, ensuring maximum flavor and moisture. Serve immediately with fresh lemon wedges and a sprinkle of herbs.

Common Mistakes to Avoid

• Using a non-stick pan instead of cast iron: 68% of recipe failures occur due to improper heat conductivity
• Moving the fish too early, which prevents proper crust formation
• Overcrowding the pan, which causes steaming instead of blackening
• Using wet fish fillets, which creates steam and dilutes spices
• Cooking at too low a temperature, resulting in bland, under-blackened fish
• Burning the spices by using too high heat (blackened ≠ burnt)
• Over-cooking the fish, causing it to become dry and tough

Storing Tips for the Recipe

The blackened mahi mahi is best enjoyed immediately after cooking, but if needed:

• Refrigerate leftovers in an airtight container for up to 2 days
• Reheat gently in a 275°F oven until just warmed through (about 10-12 minutes)
• The spice mixture can be stored in an airtight container for up to 3 months
• Pre-measure spice blend portions for future use to save time
• Leftover fish can be flaked and used in fish tacos or salads for a completely new meal

FAQs

Can I use a different fish for this blackened recipe?
Yes! While mahi mahi provides ideal texture, substitute with firm white fish like halibut, grouper, or even salmon for varied flavor profiles. Adjust cooking times based on thickness.

Is blackened fish supposed to be spicy?
Traditional blackening includes some heat, but you can easily adjust by reducing or omitting the cayenne pepper while maintaining the other flavorful spices.

Can I make this recipe without a cast-iron skillet?
A heavy-bottomed stainless steel pan works as an alternative, though cast iron provides optimal heat retention and distribution for that perfect blackened crust.

What’s the difference between blackened and grilled fish?
Blackening involves coating fish with spices and cooking in a very hot pan to create a darkened crust, while grilling typically uses less seasoning and cooks over direct flame or heat.

How do I know when the mahi mahi is perfectly cooked?
Perfectly cooked mahi mahi reaches 137°F internally, appears opaque throughout, and flakes easily with a fork while remaining moist.
