Blackened Fish Tacos with Cool Slaw
If you want a fast dinner with big flavor, these blackened fish tacos are a great choice. Flaky cod cooks in one skillet, then goes into warm corn tortillas with a cool cabbage slaw and a bright lime yogurt sauce. This meal feels a little like takeout, but it is simple enough for a busy weeknight and the steps stay clear so you can make just enough without extra fuss.

Blackened fish tacos work well when you want something satisfying but not heavy. Cod has a mild flavor and soft texture, so it cooks quickly and is easy to flake into small bites. The slaw adds crunch, while the yogurt sauce brings everything together with a creamy finish.
This recipe is also practical for cooking for one or two. You only need a short ingredient list, one skillet, and a bowl or two. If you like, you can prep the slaw ahead of time, which makes dinner even easier when you are short on energy or time.
Ingredients You’ll Need

- 8 to 10 ounces cod fillets, patted dry
- 1 tablespoon olive oil
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon ground cumin
- 1/4 teaspoon black pepper
- 1/4 teaspoon salt, or less if you prefer
- 1 cup shredded cabbage or coleslaw mix
- 2 tablespoons plain yogurt
- 1 tablespoon mayonnaise or extra yogurt
- 1 tablespoon lime juice
- 1 teaspoon water, if needed
- 4 small corn tortillas
- 2 tablespoons chopped cilantro, optional
- 2 tablespoons sliced avocado, optional
You can serve these tacos with a small side of rice, mashed potatoes, or soft bread if you like.
Step-by-Step Recipe

- Make the slaw. In a small bowl mix the cabbage, 1 tablespoon yogurt, and 1/2 tablespoon lime juice and stir well. Let it sit while you cook the fish so it softens slightly.
- Mix the seasoning. In a small dish combine the paprika, garlic powder, onion powder, cumin, black pepper, and salt.
- Season the fish. Pat the cod dry and rub both sides with the seasoning mix, pressing gently so it sticks.
- Heat the skillet. Place a nonstick or well seasoned skillet over medium heat, add the olive oil and let it warm for about 30 seconds.
- Cook the cod. Lay the fish in the pan and cook for 2 to 3 minutes on the first side, then carefully flip and cook 1 to 2 minutes more until the fish flakes easily with a fork.
- Warm the tortillas. Heat the tortillas in a dry skillet for a few seconds per side or wrap them in a damp paper towel and warm them in the microwave.
- Mix the sauce. In a small bowl stir together the remaining yogurt, mayonnaise if using, and the rest of the lime juice. Add a teaspoon of water if you want a thinner sauce.
- Assemble the tacos. Flake the fish into pieces, add it to each tortilla, top with slaw, then spoon on the lime yogurt sauce and add cilantro or avocado if you want.
