How do you blacken fish?
Blackening is a cooking technique that involves searing meat that has been coated with a spice mixture in a hot cast-iron skillet or frying pan, typically over medium to high heat.
To blacken mahi mahi, simply coat the fish with the seasoning blend and cook it in melted butter until a blackened crust forms on both sides.
Once you know how to create the spice blend, you can use it to blacken any type of fish! I like to use this blackened seasoning mix on salmon, snapper, grouper, and even flounder.
The versatility of a recipe is very important to me and this blackened mahi mahi is definitely a dish that can be enjoyed in many ways. You can simply serve it with a squeeze of fresh lemon juice over a bed of rice, alongside some grilled veggies, or with a summer salad.
If you are a fan of fish tacos, you need to use this recipe to make blackened mahi mahi tacos! They are the perfect summer meal.
Prepare fish as written here. Then, use a fork to break the fish into flakes. Place fish on warm corn tortillas with a mango salsa or pineapple salsa. Top the tacos with lime wedges and cilantro and serve!

Is blackening seasoning the same as cajun seasoning?
Blackening seasoning and cajun seasoning are very similar and can almost be used interchangeably. Cajun seasoning tends to be a little spicier.
If you want to save time when preparing this recipe, coat your mahi-mahi filet in a store bought cajun seasoning.
On the other hand, you can add some cayenne pepper and chili powder to the seasoning mixture listed here to create a simple homemade cajun seasoning.
How to make blackened mahi mahi
Step 1: Prepare seasoning mix and coat the fish
To start, mix the seasonings together in a small bowl. Then, pour it into a shallow dish. Pat the fish dry with paper towels.
Next, brush the fish fillets with the olive oil and press the fish into the seasoning mixture on the dish. You will want to try to get the filets as evenly coated as possible.
Step 2: Cook the fish
Now, it is time to heat a frying pan or cast iron skillet over medium heat and melt the butter in the pan. Place the seasoned filets in the pan and cook for 4-5 minutes, flip, and cook for an additional 4-5 minutes.
Step 3: Finish cooking and enjoy
Once the internal temperature of the fish has reached 145F, remove from the pan. Allow to cool slightly and enjoy!
Storage and reheating
Once prepared, transfer any leftovers to an airtight container. Store this blackened mahi mahi in the fridge for up to 3 days.
