  • 4 skinless firm white fish fillets such as tilapia, mahi-mahi, snapper, cod, bream, or pollock
  • 2 Tbsp melted butter for cooking the fish. You can use healthier cooking oil like avocado oil for example

Homemade Cajun Blackened Seasonings:


  • 1 lime or lemon
  • Fresh cilantro leaves or parsley


Prepare the Cajun blackened seasonings:

  • Mix all the cajun seasoning ingredients in a bowl and set aside

Marinade the fish fillets:

  • Pat each fish fillet dry with an absorbent paper towel
  • Using your hands, smear the rub all over both sides of the fish fillets evenly. Let them marinade for at least 30 minutes

Cooking the fish:

  • Put a nonstick frying pan or grill pan over a high heat and let it get nice and hot. Pour 2 Tbsp of melted butter on the pan. Place the fish fillet on the pan and cook/grill for about 3-4 minutes on each side (depending on how thick your fish fillet is). The seasonings will start to blacken nicely too. The fish will flake easily when it's fully cooked. Remove from the pan to serving platter
  • Garnish with lime/lemon slices and some fresh herb like cilantro leaves or parsley leaves
