List of Main Ingredients
- 1 lb white fish fillets (tilapia or cod)
- 2 tablespoons Cajun seasoning
- 2 tablespoons extra virgin olive oil
Additional Ingredients for Slaw
- 1 cup finely shredded cabbage

For this dish, I choose fresh fish like tilapia or cod. They are mild and flaky. The Cajun seasoning adds a warm kick. It makes the fish bold and exciting. I use olive oil to help the fish cook evenly and create a crispy texture.
For the slaw, I prefer a mix of shredded cabbage and carrots. The cabbage adds crunch, while the carrots bring a bit of sweetness. Fresh cilantro gives it a bright flavor. This mix balances the spicy fish perfectly.
When serving, I love adding creamy Greek yogurt or sour cream. It cools down the heat from the seasoning. Slices of ripe avocado add richness and make each bite creamy. A squeeze of lime brightens everything up. If you like spice, don't forget the hot sauce!

Step-by-Step Instructions
Preparing the Fish
Start with the fish fillets. Pat them dry using a paper towel. This step helps the seasoning stick. Next, coat both sides with Cajun seasoning. Press it in well to ensure a strong flavor.
Cooking the Fish
Heat olive oil in a large skillet over medium-high heat. Wait until the oil shimmers. Carefully add the seasoned fish fillets. Cook for about 3-4 minutes on each side. The fish should blacken and flake easily with a fork. Once done, take it off the heat and flake it into large chunks.
Making the Slaw
In a large mixing bowl, combine shredded cabbage, carrots, and chopped cilantro. Add a pinch of salt and pepper. Drizzle fresh lime juice over the mix. Toss everything together until it is evenly coated. Taste it to see if you need to adjust the flavors.
Warming the Tortillas
Warm the corn tortillas in a dry skillet. You can also warm them over a gas flame. Heat each side for about 30 seconds. This makes the tortillas soft and pliable.
Assembling the Tacos
Take a warmed tortilla and add a generous amount of blackened fish. Top it with the colorful slaw. Add a couple of avocado slices. Drizzle some Greek yogurt or sour cream for creaminess.
Serving the Tacos
Arrange the tacos on a bright platter. Serve with lime wedges for squeezing over the top. Add hot sauce for those who want some heat. Make it look inviting with a sprinkle of fresh cilantro.
Tips & Tricks
Perfecting the Blackened Seasoning
To get the best flavor, coat the fish well. Pat the fish dry first. This helps the seasoning stick. Use a good amount of Cajun seasoning. Press it onto both sides of the fish. This gives a strong taste. You can mix your seasoning, too. Try adding smoked paprika for a deeper flavor.
Ensuring Fish is Cooked Properly
You want your fish to flake easily. Cook it for about 3-4 minutes per side. Look for a nice, dark crust. The fish should not be translucent. When done, it should be opaque and firm. Use a fork to check. If it flakes apart, it’s ready.
Slaw Variations
Slaw can be fun to change up. You can add different colors and flavors. Use red cabbage for a pop of color. Try adding bell peppers for crunch. You can also mix in apples for sweetness. For a spicy kick, add jalapeños. The key is to balance flavors with lime juice and salt.
Pro Tips
- Fish Freshness: Always choose the freshest fish available for the best flavor and texture. Look for fish with a clean, ocean-like smell and firm flesh.
- Perfectly Blackened: Make sure your skillet is hot enough before adding the fish to achieve that crispy blackened crust. If the oil shimmers, you're ready to go!
- Customize Your Slaw: Feel free to add additional ingredients like diced bell peppers or jalapeños to your slaw for extra crunch and flavor.
- Warm Tortillas: Warming your tortillas over an open flame can add a nice smokiness. Just be sure to watch them closely to avoid burning!
Variations
Alternative Fish Options
You can use many types of fish for these tacos. Salmon, mahi-mahi, and shrimp are great choices. Salmon brings a rich flavor and melts in your mouth. Mahi-mahi has a firm texture and light taste. Shrimp cooks quickly and adds a sweet touch. Each option creates a tasty taco that everyone will love.
Different Tortilla Choices
When it comes to tortillas, you have options. Corn tortillas are traditional and gluten-free. They add a nice flavor and hold the filling well. Flour tortillas are softer and bigger, making them easy to fill. Choose based on your taste or dietary needs. Both options work well with blackened fish.
Customizing Slaw Ingredients
The slaw can be your canvas. You can add herbs like dill or parsley for a fresh twist. Want more crunch? Try adding radishes or jicama. You can also mix in some diced apples for sweetness. Customizing the slaw makes your tacos unique and fun. Explore different flavors to find your perfect mix.
Storage Info
Storing Leftovers
To keep your blackened fish tacos fresh, store them in an airtight container. Place the fish and slaw in separate containers. This helps keep the fish from getting soggy. Use the leftovers within two days for the best taste. You can also wrap the tortillas in foil for extra protection.
Reheating Instructions
When you’re ready to enjoy the leftovers, gently reheat the fish. You can use a skillet over low heat. This helps to keep the fish moist. Warm the tortillas in a dry skillet, just like before. Heat them for about 30 seconds on each side. This way, they stay soft and pliable.
Freezing Tips
You can freeze the blackened fish, but it's best to avoid freezing the tortillas or slaw. Wrap the fish tightly in plastic wrap and then foil. It’s good for up to two months in the freezer. When you're ready to eat, thaw the fish in the fridge overnight. Reheat it as mentioned before for a tasty meal.
