Equipment

  • Cast iron skillet or heavy-bottomed pan
  • Mixing Bowls
  • Tongs or Spatula
  • Measuring spoons
  • Sharp Knife
  • Cutting board
  • Small whisk or fork
  • Serving Platter or Plates

Ingredients
  

For the Blackened Fish

  • 1 lb firm white fish fillets like cod, tilapia, or mahi-mahi
  • 2 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dried oregano
  • 1 tsp dried thyme
  • ½ tsp cayenne pepper adjust to taste
  • ½ tsp salt
  • ½ tsp black pepper
  • 2 tbsp unsalted butter or olive oil

For the Tacos

  • 8 small flour or corn tortillas
  • 2 cups shredded cabbage or slaw mix
  • ½ cup chopped fresh cilantro
  • 1 lime cut into wedges

For the Sauce

  • ½ cup mayonnaise
  • 2 tbsp sour cream
  • 1 tsp hot sauce optional, for extra kick
  • 1 tsp lime juice
  • ½ tsp smoked paprika

Instructions
 

Prepare the Blackening Spice

  • In a small bowl, combine smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, salt, and black pepper.
  • Whisk together until evenly blended.
  • Pro Tip: Measure each spice carefully—getting the balance right makes these the best fish tacos.

Prep the Fish

  • Pat the fish fillets dry with paper towels. This helps the spice stick and creates a nice crust.
  • Sprinkle the blackening spice evenly on both sides of the fillets. Press lightly so the spices adhere.
  • Pro Tip: Don’t skimp on pressing the spice in—it locks in flavor and forms that signature blackened edge.

Make the Sauce

  • In a small bowl, mix mayonnaise, sour cream, hot sauce (if using), lime juice, and smoked paprika.
  • Whisk until smooth and creamy.
  • Pro Tip: Taste and adjust seasoning—add a touch more lime or hot sauce if you like it zesty.

Cook the Fish

  • Heat the cast iron skillet over medium-high heat until hot.
  • Add butter or olive oil and let it melt.
  • Carefully place the fillets in the skillet. Cook 3–4 minutes per side, depending on thickness, until the fish flakes easily with a fork.
  • Pro Tip: Don’t move the fish around too much—it needs contact with the hot pan to form the perfect crust.

Warm the Tortillas

  • Heat tortillas in a dry skillet for 20–30 seconds per side, just until soft and pliable.
  • Keep them warm by wrapping in a clean kitchen towel until ready to assemble.
  • Pro Tip: Warming the tortillas prevents cracking when you fold them around the fish.

Assemble the Tacos

  • Lay a tortilla flat and spread a thin layer of the sauce.
  • Place a piece of blackened fish on top.
  • Add shredded cabbage and a sprinkle of chopped cilantro.
  • Finish with a squeeze of lime and a little extra sauce if desired.
