Ingredients for Blackened Fish Tacos

Here’s a breakdown of what you’ll need to make these tacos. (Exact measurements are in the recipe card below.)

For the Fish:

• White Fish Fillets: Use about 1 pound. Tilapia, cod, or mahi-mahi are all good choices. These types of fish are mild and cook quickly, making them perfect for tacos.
• Olive Oil: You’ll brush the fillets with oil so the spices stick and the fish stays moist.
• Unsalted Butter: Adds flavor and helps the fish brown in the skillet.
• Blackening Spice Mix:
  • Garlic powder
  • Paprika (smoked or sweet)
  • Onion powder
  • Cayenne pepper (for a touch of heat; use less or skip for less spicy)
  • Dried thyme
  • Dried basil
  • Dried oregano
  • Garlic salt
  • Kosher salt
  • Black pepper

For the Creamy Sauce:

• Sour Cream: Forms the base of the sauce.
• Mayonnaise: Adds richness and helps blend the flavors.
• Chipotle Pepper in Adobo Sauce: Adds smoky heat. Use just a small amount, finely chopped, for kids or those who like less spice.
• Lime Juice: Freshly squeezed for tangy flavor.
• Garlic Salt: For seasoning.

For the Tacos:

• Taco-Sized Tortillas: Corn or flour tortillas, warmed before serving.
• Fresh Cilantro: Chopped, for bright flavor and color.
• Toppings: Optional, but tasty. You can use thinly sliced cabbage, shredded lettuce, diced tomatoes, sliced avocado, radishes, or a squeeze of extra lime juice.

Variations for Blackened Fish Tacos

• Try Different Proteins: Salmon or peeled shrimp work well instead of white fish. Cooking times will change—shrimp need less time.
• Make it Dairy-Free: Skip the sour cream and mayonnaise in the sauce. Use mashed avocado or plain non-dairy yogurt for creaminess.
• Add Crunch: Use a handful of thinly sliced cabbage or coleslaw mix for extra crunch and color.
• Sweeten Things Up: Top with fresh mango salsa or pineapple for a tropical touch.
• Adjust the Heat: Use more or less cayenne and chipotle to make the tacos as spicy or mild as you like.

How to Make Blackened Fish Tacos Step-by-Step

1. Mix the Blackening Spices

In a small mixing bowl, add all the dried spices—garlic powder, paprika, onion powder, cayenne, thyme, basil, oregano, garlic salt, kosher salt, and black pepper. Stir well to combine. This spice mix will give the fish its dark, flavorful crust.

2. Prepare the Fish

Pat the fish fillets dry with paper towels. This step is important so the spices stick and the fish browns instead of steaming. Lay the fillets on a plate or cutting board. Brush both sides with a little olive oil. Sprinkle the blackening spice mix evenly over all sides of the fish. Gently press the spices in with your fingers so they coat the fillets well.

3. Make the Creamy Sauce

In a small bowl, combine the sour cream, mayonnaise, chopped chipotle pepper with adobo sauce, lime juice, and a pinch of garlic salt. Stir until the sauce is smooth and creamy. Taste and add more lime juice or chipotle, if you like. Set the sauce aside until you’re ready to assemble your tacos.

How to Cook the Fish

4. Heat the Skillet

Place a large skillet (cast-iron works best, but nonstick is fine) on the stove over medium-high heat. Let it heat up for about 2-3 minutes. You want the pan to be hot before you add the fish. This is what helps the spices “blacken” and form a flavorful crust.

5. Cook the Fish

Add 1 tablespoon of olive oil and 1 tablespoon of unsalted butter to the hot skillet. Swirl them around so the bottom is coated.

Carefully place the seasoned fish fillets in the pan. You should hear a gentle sizzle. Cook without moving for 2-3 minutes, until the underside looks dark and crispy. Gently flip the fish using a spatula or tongs. Cook the other side for another 2-3 minutes, or until the fish flakes easily with a fork and is opaque all the way through.

If you have thicker fillets, you might need to lower the heat a little and cook an extra minute per side. For thinner fillets, watch closely to prevent overcooking.

Tip: If your skillet is small, cook the fish in batches so you don’t crowd the pan.

6. Rest and Flake the Fish

Transfer the cooked fish to a clean plate and let it rest for a minute or two. This helps keep it juicy. Use a fork to gently break the fish into big flakes or bite-sized pieces. Remove any small bones you find.

Warm the Tortillas

While the fish is resting, warm your tortillas. You can do this in a dry skillet over medium heat for 30 seconds on each side, or wrap a stack in a damp paper towel and microwave for 30 seconds. Warm tortillas are softer and won’t crack when you fold them.

Assemble the Tacos

Now comes the fun part—putting your tacos together.

1. Lay a warm tortilla flat on your plate.
2. Spoon a little creamy chipotle sauce down the middle.
3. Add a generous amount of flaked blackened fish on top.
4. Sprinkle with chopped cilantro and your favorite fresh toppings, like sliced cabbage, radish, or avocado.
5. Add a squeeze of fresh lime juice if you like.

Repeat with the remaining tortillas and ingredients.

Serving and Decoration

Arrange the tacos on a platter or individual plates. For a colorful meal, serve with lime wedges, extra chopped cilantro, and a small bowl of the creamy sauce for dipping. You can also set out extra toppings—such as salsa, diced tomatoes, or shredded lettuce—so everyone can build their own taco just the way they like.

Storing Blackened Fish Tacos

Cooked Fish:
If you have leftover cooked fish, let it cool to room temperature, then store it in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet or microwave until just warm. Try not to overheat, as this can dry out the fish.

Taco Sauce:
The creamy sauce can be made ahead and stored in a covered container in the refrigerator for up to 3 days.

Tortillas:
Wrap leftover tortillas in a paper towel and store in a resealable bag. Warm them again before using.

Tips and Tricks for Success

• Don’t Skip Drying the Fish: Moisture on the surface will keep the spices from sticking and stop the crust from forming.
• Use Enough Heat: The skillet needs to be hot enough to “blacken” the fish but not so hot it burns the spices.
• Don’t Overcrowd the Pan: Cook fish in batches if needed, so each piece browns well.
• Prep Toppings Ahead: Chop toppings and mix the sauce before you start cooking the fish, so everything is ready to go.
• Adjust the Spice: If you want milder tacos, use less cayenne or chipotle pepper.
