Instructions

  • Preheat a large skillet over medium heat. 
  • In a small bowl, mix together 1 teaspoon paprika, 1 teaspoon chili powder, 1 teaspoon garlic powder, 1/2 teapsoon kosher salt, 1/2 teaspoon ground black pepper, 1/2 teaspoon dried oregano, 1/2 teaspoon onion powder, and 1/4 teaspoon ground cayenne pepper until combined. Stir in 1 tablespoon avocado oil or olive oil until well combined.
  • Pat 4 (6 ounce) cod filets dry with paper towels. Brush both sides of each cod filet generously with the spice and oil mixture.
  • Add cod filets to the preheated skillet. Cook for 3-4 minutes on the first side without moving. Flip and cook for an additional 3-4 minutes on the second side, until cod is cooked through. Cod should reach an internal temperature of 145°F and the flesh should be opaque and easily flaked with a fork.
  • While the cod is cooking, prepare the avocado corn salsa. In a bowl, combine 1 cup corn, 1 avocado, 1 tomato, 1/4 cup red onion, 2 tablespoons cilantro, 1 tablespoon lime juice, and 1/4 teaspoon kosher salt. Stir gently to combine. Taste and add more lime juice or salt as needed.
  • Transfer cooked cod filets to serving plates. Top each filet with avocado corn salsa and serve immediately.

Notes

  • Gluten-free: This recipe is naturally gluten-free. No substitutions needed.
  • Make it less spicy: Omit the cayenne pepper for a milder version. You can also add 1/2 teaspoon brown sugar to the spice mix to balance the heat.
  • How to tell when cod is cooked: Cod should reach an internal temperature of 145°F. The flesh should be opaque (not translucent) and easily flake with a fork.
  • Use other fish: This blackening spice works great on mahi mahi, tilapia, salmon, or halibut. Adjust cooking time based on the thickness of your fish filets.
  • Storage: Store leftover cod in an airtight container in the refrigerator for 1-2 days. Reheat gently in a skillet over low heat. Store salsa separately in an airtight container for up to 1 day. The avocado will start to brown.
