Pickled onions:

  • ½ cup white vinegar
  • 1 tablespoon honey
  • 2 teaspoons kosher salt, divided
  • ½ red onion, thinly sliced

Fish:

  • 1 tablespoon paprika*
  • 2 teaspoons ground cumin
  • 2 teaspoons dried Mexican oregano (marjoram or regular dried oregano also work)
  • 1 teaspoon ground black pepper
  • ¼ –½ teaspoon cayenne
  • 4 (4-ounce) cod fillets (halibut or mahi-mahi also work well)
  • 2 tablespoons extra-virgin olive oil

Sauce:

  • ¼ cup mayonnaise
  • ¼ cup Greek yogurt
  • 1 lime, juiced and zested
  • ½ teaspoon paprika

To serve:

  • 4 –8 (6-inch) corn or flour tortillas
  • 2 cups arugula
  • 1 cup canned black beans, drained and rinsed
  • Lime wedges

Instructions

  • Bring vinegar, ½ cup water, honey, and 1 teaspoon salt to a boil in a small saucepan. Add onion to a medium bowl. Pour boiling vinegar mixture over onion mixture and let sit at least 15 minutes.

  • Heat a large cast-iron skillet or nonstick skillet set over medium for 3 minutes. Add 1 tablespoon of oil to skillet, swirl to coat, then add 2 fish fillets. Cook fillets just until starting to blacken, about 4 minutes. Flip the fillets and cook 3–4 minutes more until blackened on second side and a thermometer inserted in the thickest parts registers between 140ºF and 145ºF; transfer to a plate.

  • Combine mayonnaise, yogurt, 1 tablespoon lime juice, 1 teaspoon lime zest, and ½ teaspoon paprika; season with salt and pepper to taste.

  • Using tongs, char tortillas over an open flame on the stove top, turning frequently to char all over.
  • Serve blackened fish in charred tortillas with arugula, black beans, pickled onions and sauce. Finish with a squeeze of lime and fresh cilantro.

Notes

* use a combo of sweet paprika and smoked paprika if you want the tacos to be extra smoky!
MAKE DAIRY-FREE: skip the yogurt in the sauce and use ½ cup mayonnaise.
TIMING: cook time largely depends on how thick your fillets are. My fillets were 3/4-inch to 1-inch thick. If you have thinner fillets, drop the cooking time down by a minute or more.
