What you will need
This recipe uses 10 simple ingredients that you can find at any grocery store:
- 1.5 lbs tilapia fillets
- 2 tbsp Cajun seasoning
- 1 tsp smoked paprika
- 2 tbsp olive oil
- 8 pieces small flour tortillas
- 2 cups shredded cabbage
- 0.5 cup sour cream
- 2 tsp chipotle in adobo sauce
- 1 whole lime
- 0.25 cup fresh cilantro
Step by step instructions
Step 1: Season the Fish
Pat tilapia fillets completely dry with paper towels. Combine Cajun seasoning and smoked paprika in a small bowl. Coat both sides of each fillet generously with the spice mixture pressing firmly so it adheres.
Step 2: Make Chipotle Crema
In a small bowl whisk together sour cream and chipotle in adobo sauce until smooth. Add a squeeze of lime juice and a pinch of salt. Set aside in the refrigerator until ready to serve.
Step 3: Cook the Fish
Heat olive oil in a cast iron skillet over high heat until it begins to smoke. Add the seasoned fillets and cook without moving them for 3 to 4 minutes per side until a dark blackened crust forms and fish flakes easily.
Step 4: Warm Tortillas and Prep Slaw
While the fish rests warm tortillas directly over a gas flame or in a dry skillet for 30 seconds per side. Toss shredded cabbage with a squeeze of lime juice and a pinch of salt to make a quick slaw.
Step 5: Assemble and Serve
Break the cooked fish into large chunks and divide among the warm tortillas. Top with chipotle crema, lime slaw, and fresh cilantro. Serve immediately with extra lime wedges on the side.

- tilapia → mahi mahi or catfish
- sour cream → Greek yogurt
- flour tortillas → corn tortillas for gluten free
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Not drying the fish before seasoning which prevents a proper blackened crust from forming
- Using too low heat which steams the fish instead of creating the signature char
- Moving the fish too early in the pan which causes it to break apart before the crust sets
