Ingredients
For the Fish and Tacos:
- 1.5 pounds tilapia fillets approximately four 5-ounce pieces
- 6 to 8 corn tortillas 6-inch size, warmed
- ½ cup Mexican cheese blend adjust to taste
- 2 tablespoons olive oil divided
- 1 tablespoon butter
For the Marinade:
- 3 tablespoons olive oil
- 3 tablespoons fresh lime juice
- 1 tablespoon low-sodium soy sauce
- 1½ tablespoons homemade spice rub see below
Homemade Spice Rub:
- 1 tablespoon ancho chili powder
- 1 tablespoon brown sugar
- 1 teaspoon smoked paprika
- 1 teaspoon ground cumin
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- ½ teaspoon dried oregano
- ½ teaspoon black pepper
- ¼ teaspoon cayenne pepper optional, for heat
For the Pineapple Cucumber Slaw:
- 2 cups fresh pineapple chopped
- 2 cups thinly sliced red cabbage
- 1 medium cucumber peeled and chopped
- ¼ cup finely chopped red onion
- ½ cup loosely packed fresh cilantro chopped
- 1 tablespoon fresh lime juice
- Salt and pepper to taste
For the Avocado Crema:
- 1 medium ripe avocado
- ½ cup sour cream
- 2 tablespoons mayonnaise
- 1 tablespoon fresh lime juice
- ½ teaspoon salt
- ¼ teaspoon ground cumin
- ¼ teaspoon garlic powder
Instructions
- Prepare the Spice Rub: In a medium bowl, combine ancho chili powder, brown sugar, smoked paprika, cumin, garlic powder, onion powder, salt, oregano, black pepper, and cayenne pepper (if using). Mix thoroughly. Set aside about 1½ tablespoons for the marinade; the remainder will be used to coat the fish later.
- Make the Marinade and Marinate the Fish: In a large resealable plastic bag, whisk together the olive oil, lime juice, soy sauce, and 1½ tablespoons of the prepared spice rub. Add the tilapia fillets, seal the bag, and gently toss to coat the fish evenly. Let the fish marinate at room temperature for 30 minutes to absorb the flavors.
- Prepare the Avocado Crema: While the fish marinates, add avocado, sour cream, mayonnaise, lime juice, salt, cumin, and garlic powder to a blender or food processor. Blend until smooth and creamy, scraping down the sides if needed. Transfer to an airtight container and chill until ready to serve.
- Toss the Pineapple Cucumber Slaw: In a large mixing bowl, combine pineapple, red cabbage, cucumber, red onion, cilantro, lime juice, and a pinch of salt and pepper. Toss gently to mix all ingredients well. Cover and refrigerate until serving time.
- Coat the Fish with Spice Rub: Remove the tilapia from the marinade and pat each fillet dry with paper towels to remove excess moisture.In a small bowl, mix the remaining spice rub with 1 tablespoon of olive oil to form a paste. Rub this mixture evenly over each fillet. Let the fish rest for 15 minutes at room temperature to intensify the flavors.
- Cook the Tilapia: Heat a large cast iron skillet over medium-high heat. Add 1 tablespoon olive oil and 1 tablespoon butter, allowing the butter to melt completely. Once the pan is hot and sizzling, carefully place the tilapia fillets in the skillet. Cook for about 3 minutes on each side, or until the fish is nicely blackened on the outside and flakes easily with a fork.
- Assemble the Tacos: Break the cooked tilapia into large chunks. Warm the corn tortillas and distribute the fish evenly among them. Sprinkle with Mexican cheese blend, then top generously with the pineapple cucumber slaw and avocado crema. Optionally, garnish with fresh lime wedges and your favorite hot sauce for an extra kick.
Notes
- Marinating Tip: Do not marinate the fish for longer than 30–60 minutes to avoid the lime juice “cooking” the fish and making it mushy.
- Spice Level: Adjust the amount of cayenne pepper in the rub according to your heat preference. Omit it entirely for a mild flavor.
- Tortilla Warming: To prevent cracking, warm corn tortillas in a dry skillet over medium heat for 30 seconds each side or wrap in a damp paper towel and microwave for 20 seconds.
- Make Ahead: Both the avocado crema and slaw can be prepared a day ahead and refrigerated to save time. Just toss the slaw again before serving.
- Serving Suggestion: These tacos pair wonderfully with a side of black beans, Mexican rice, or a simple green salad for a complete meal.
Chef’s Secrets for Perfect Tacos
The key to creating irresistible blackened tilapia tacos lies in balancing bold flavors with fresh ingredients.
Marinating the fish for exactly 30 minutes allows the lime juice and soy sauce to infuse the fillets without overpowering or “cooking” them, preserving their tender texture.
The homemade spice rub, rich with ancho chili and smoked paprika, delivers a smoky depth while the brown sugar balances heat with subtle sweetness.
Using a hot cast iron skillet ensures a perfect blackened crust that locks in moisture.
When cooking, avoid overcrowding the pan to maintain high heat for a proper sear.
For the creamiest avocado crema, choose ripe avocados and blend thoroughly to achieve a silky consistency.
Finally, fresh pineapple in the slaw adds a refreshing contrast, elevating the tacos to restaurant-quality flavor without complexity.
Serving Suggestions to Elevate Meals
These blackened tilapia tacos shine when served with vibrant sides that complement their fresh, smoky profile.
Pair them with a crisp Mexican street corn salad or a simple black bean and cilantro salad for added texture and nutrition.
A side of lime-infused Mexican rice or cauliflower rice works well for a more filling meal.
For an extra burst of flavor, drizzle some chipotle hot sauce or a squeeze of fresh lime over the tacos.
Garnishing with additional cilantro or pickled jalapeños adds brightness and subtle heat.
For beverages, a cold Mexican lager or a citrusy margarita perfectly balances the smoky spice and creamy avocado notes in the dish.
Storage Tips for Best Freshness
To keep your blackened tilapia tacos tasting fresh, store the components separately. Refrigerate the cooked fish in an airtight container for up to 2 days to maintain its delicate texture.
The pineapple cucumber slaw can be stored in the fridge for 2 to 3 days and tastes best when tossed again before serving to redistribute the dressing.
Avocado crema is best consumed within 24 hours to prevent browning; storing it tightly covered with plastic wrap pressed onto the surface helps reduce oxidation.
Tortillas should be wrapped in foil or plastic and refrigerated if not consumed immediately, then warmed before serving.
Avoid assembling tacos in advance to prevent sogginess.
