Ingredients

  • 1 lb. mahi mahi
  • 1 Tbsp. blackened seasoning
  • ¼ - ½ tsp. salt to taste
  • 2 Tbsp. butter or oil
  • Lemon wedges optional
  • Fresh parsley optional

Instructions

  • Cut the mahi mahi into 4 equal-sized filets and pat the fish dry with a paper towel.
  • Sprinkle 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.
  • Serve blackened mahi mahi with lemon wedges and a sprinkle of fresh parsley. Enjoy!

Notes

Meal Prep and Storage

  • To Prep-Ahead: Make the seasoning mix beforehand so it is ready. You can slice the fish into fillets a couple of hours before cooking and keep them wrapped in the fridge.
  • To Store: Wrap whatever is leftover and keep in the fridge for up to 2 to 3 days.
  • To Freeze: While this fish is best enjoyed immediately, you can tightly wrap mahi-mahi and store it in the freezer for up to 3 to 4 months.
  • To Reheat: Warm up thawed mahi-mahi in a skillet on the stove, or place it in a 275℉ oven for about 15 minutes.
