Ingredients

For the Blackened Fish:

  • 1 lb white fish cod, tilapia, mahi mahi, or snapper
  • 1 tbsp olive oil
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp dried thyme
  • ½ tsp dried oregano
  • ¼ tsp cayenne pepper adjust to taste
  • Salt & pepper to taste
  • Juice of ½ lime

For the Lime Slaw:

  • 2 cups shredded cabbage
  • ¼ cup mayo or plain Greek yogurt
  • 1 tbsp fresh lime juice
  • 1 tsp honey
  • Salt & pepper to taste

For Assembly:

  • 8 small corn or flour tortillas
  • 1 avocado sliced
  • Fresh cilantro
  • Extra lime wedges
  • Optional: hot sauce pickled onions, salsa

Instructions

  • In a small bowl, mix all the blackening spices. Pat fish dry and coat it with olive oil, lime juice, and spice mix.
  • Heat a skillet over medium-high heat. Cook fish 3–4 minutes per side until blackened and fully cooked. Remove and flake.
  • In a bowl, toss together shredded cabbage, mayo, lime juice, honey, salt, and pepper to make slaw.
  • Warm tortillas in a dry skillet or microwave wrapped in a damp paper towel.
  • Assemble tacos with slaw, flaked fish, avocado, and desired toppings. Serve with lime wedges and enjoy immediately.

Notes

  • Fish options: Use any firm white fish like cod, tilapia, or mahi mahi — or try salmon for a richer version.
  • Make it dairy-free by using vegan mayo or avocado instead of yogurt in the slaw.
  • Adjust the heat by adding more or less cayenne, or swap for chili powder if preferred.
  • Double the slaw — it’s great on burgers, sandwiches, or grain bowls!
