What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat tilapia fillets completely dry before seasoning to ensure a proper blackened crust.
- 2Use a well-seasoned cast iron skillet and get it smoking hot before adding the fish.
- 3Don't move the fish while searing — let it cook undisturbed for a dark, crisp crust.
- 4Work in batches if needed; overcrowding steams the fish and ruins the blackened effect.
- 5Warm tortillas directly over a gas flame or in a dry skillet for authentic char and pliability.
- 6Make the mango salsa up to 4 hours ahead and refrigerate for deeper flavor.
- 7Leftover blackened tilapia keeps in the fridge for 2 days; reheat gently in a skillet.
