Ingredients

Scale
  • 1.5 lbs cod fillets
  • 1/4 cup avocado oil (or olive oil)
  • 1 tsp lime zest
  • 2 tbsp freshly squeezed lime juice
  • 1 large garlic clove, minced
  • 1 1/2 tsp chili powder
  • 1 tsp paprika
  • 1 1/2 tsp dried oregano
  • 1/4 tsp black pepper
  • 1/2 tsp sea salt

Instructions

  1. If using frozen cod, thaw fully overnight in the fridge or under cold running water.
  2. Preheat oven to 400°F (200°C).
  3. In a small bowl, whisk together avocado oil, lime zest, lime juice, minced garlic, chili powder, paprika, dried oregano, black pepper, and sea salt.
  4. Pat cod fillets dry with paper towels and place them in a shallow dish or a sealable bag.
  5. Pour the marinade over the cod and gently toss or massage to coat each fillet; seal and refrigerate for at least 30 minutes (up to 10 hours).
  6. Arrange the marinated cod fillets and any remaining marinade in a baking dish in a single layer.
  7. Bake at 400°F (200°C) for 12–15 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 140–145°F (60–63°C).
  8. Let the baked cod rest for a few minutes, then sprinkle with chopped fresh parsley or sliced green onions if desired.

Notes

Use fresh cod, preferably wild-caught, for best flavor and texture., Avoid overcooking the cod to keep it moist and tender., Adjust the spice level by increasing or decreasing chili powder and paprika; add cayenne or jalapeños for more heat., Serve with sides like roasted vegetables, cauliflower rice, or coconut rice for a complete meal., For meal prep, marinate up to 10 hours ahead and store leftovers in an airtight container refrigerated for 2-3 days or frozen up to 2-3 months., Reheat leftovers in a 350°F oven covered with foil for 10-15 minutes to maintain moisture., This recipe can be adapted by substituting cod with other mild white fish, salmon, or shrimp (adjust cooking times accordingly)., The dish can also be grilled using the same marinade, cooking 4-5 minutes per side on a hot oiled grill.
