Ingredients

Scale

For the Fish:

  • 6 to 7 tilapia filets (fresh or thawed if frozen)

  • 2 tablespoons olive oil

For the Seasoning Mix:

  • ½ teaspoon seasoning salt

  • ½ teaspoon cayenne pepper

  • ½ teaspoon paprika

  • ½ teaspoon garlic salt

  • Pinch of ground chili powder

  • 1 teaspoon regular salt

  • ¼ teaspoon black pepper

Ingredient Flexibility:
If you don’t have garlic salt, substitute with ¼ teaspoon garlic powder and a small pinch of salt. You can also adjust the heat level by reducing or omitting the cayenne pepper and chili powder.

For the Toppings:

  • 1 small purple cabbage, finely sliced

  • 1 small onion, chopped (white or red)

  • 3 tomatoes, chopped

  • 2 tablespoons chopped cilantro

  • 1 avocado, peeled, pitted, and diced

  • 2 limes, cut into wedges

  • 1 container queso fresco (crumbled)

  • 4 oz. Monterey Jack cheese, shredded

Optional Additions or Swaps:
If you don’t have queso fresco, use feta cheese or skip the cheese entirely. No Monterey Jack? Try cheddar or a mild Mexican blend. If you’re not a fan of cabbage, shredded lettuce will work too.

For the Sauce (Optional but Recommended):

The original recipe mentions a fish taco sauce, so here’s a basic version you can quickly whip up:

Simple Fish Taco Sauce:

  • ½ cup plain Greek yogurt or sour cream

  • 2 tablespoons mayonnaise

  • 1 tablespoon lime juice

  • 1 teaspoon hot sauce (or to taste)

  • ½ teaspoon garlic powder

  • Salt to taste

Whisk everything together in a bowl until smooth and creamy. Refrigerate until ready to serve.

Tortillas:

  • 10 to 12 small corn or flour tortillas, depending on your preference

Instructions

  • Prep the Fish
    If your Tilapia is frozen, be sure it’s fully defrosted before you begin. You can thaw it in the fridge overnight or place the sealed fish in a bowl of cold water for about 30 minutes. Once defrosted, remove the filets from their packaging and pat them dry with paper towels.
  • Mix the Seasonings
    In a small bowl, combine the seasoning salt, cayenne, paprika, garlic salt, chili powder, salt, and pepper. Stir well until evenly blended.
  • Season the Fish
    Brush each Tilapia filet with olive oil on both sides. Sprinkle the seasoning mix evenly over the fish, gently rubbing it in so it adheres.
  • Cook the Fish
    Preheat your grill or oven. On a grill, cook the filets for about 4–5 minutes on each side, or until the fish flakes easily with a fork and is opaque throughout. If using an oven, bake at 400°F (200°C) for 10–12 minutes on a foil-lined tray, flipping once halfway through.
  • Chop and Prepare the Toppings
    While the fish is cooking, chop your toppings: shred the cabbage, dice the onion and tomatoes, chop the cilantro, and cube the avocado. Place everything into separate bowls for easy assembly.
  • Make the Sauce
    Mix the sauce ingredients (see above) in a small bowl and chill until ready to serve. This sauce adds a tangy, creamy contrast to the warm fish and crunchy toppings.
  • Warm the Tortillas
    Heat the tortillas in a dry skillet for about 30 seconds per side, or wrap them in foil and warm them in the oven for 5–7 minutes.
  • Assemble the Tacos
    Once the fish is cooked, break it into large chunks with a fork. Fill each tortilla with a few pieces of fish, then top with cabbage, onion, tomato, avocado, cheese, and a drizzle of sauce. Serve with lime wedges for squeezing over the top.

Notes

  • Don’t Overcook the Fish
    Tilapia cooks quickly. If you overcook it, it can become dry or rubbery. You’ll know it’s done when it flakes easily with a fork and is white all the way through.
  • Prep Efficiently
    While the fish is cooking, take that time to prepare your toppings and sauce. Multitasking saves time and keeps things moving smoothly.
  • Use What You Have
    You don’t need every topping listed. Even just cabbage, onion, and sauce will still taste great. The key is contrast: something crunchy, something creamy, and a pop of fresh flavor.
  • Avoid a Soggy Taco
    Warm tortillas help keep your tacos from falling apart. Also, layer dry toppings like cabbage first, followed by fish and sauces to keep things balanced.
  • Grill Alternative
    If you don’t have a grill, a stovetop skillet or oven will work just fine. For extra crispness, try pan-searing the fish in a little oil over medium heat.
