How to Make Blackened Fish Tacos with Cabbage Slaw

Step 1: Make the chipotle aioli.
Combine all of the aioli ingredients in a tall cup suited for an immersion blender. Blend starting at the bottom and gradually working upward until everything is fully combined and smooth. Refrigerate until ready to use — this resting time also allows the flavors to meld together.

Step 2: Make the coleslaw.
Combine all of the coleslaw ingredients in a bowl and stir until everything is evenly mixed. Refrigerate until you’re ready to assemble the tacos, which helps it stay crisp and cold.

Step 3: Season the fish.
In a small bowl, mix together the cumin, chili powder, paprika, garlic powder, onion powder, and salt. Rub this spice blend generously onto both sides of the fish pieces.

Step 4: Cook the fish.
Heat olive oil in a skillet over medium-high heat. Add the seasoned fish and cook for 3–4 minutes per side, until it easily flakes apart with a fork. Remove from the heat once done.

Step 5: Assemble the tacos.
Prepare the tortillas according to the package directions. Fill each one with a portion of the blackened fish and coleslaw, then top with the chipotle aioli and any additional toppings you’d like.

Tips for the Best Results

• Don’t overcook the fish. White fish cooks quickly, and pulling it as soon as it flakes easily keeps it tender rather than dry.
• Make the aioli and slaw ahead of time. Both can be prepared in advance and kept chilled, which speeds up assembly when you’re ready to eat.
• Rub the spice blend in firmly. This helps the seasoning adhere well and creates that signature blackened crust when the fish hits the hot pan.
• Warm the tortillas before filling. This makes them more pliable and helps prevent cracking when folded.
• Adjust the heat level in the aioli. Add more or less chipotle adobo sauce depending on how spicy you’d like the sauce to be.

Storage & Reheating

Store the fish, slaw, and aioli separately in airtight containers in the fridge for up to 2–3 days. Reheat the fish gently in a skillet or microwave, and assemble the tacos fresh with cold slaw and aioli for the best texture and flavor.

Serving Suggestions

• With a side of rice and refried beans for a complete meal
• Topped with extra lime juice for added brightness
• Paired with tortilla chips and salsa as a starter
• Served alongside a simple corn salad for a summery side
