Notes

Storage: Store leftover blackened cod in an airtight container in the refrigerator for 2–3 days. To reheat, warm in a hot skillet for best results, microwaving fish is not recommended.

Ingredients: Both fresh and frozen cod work well here – use whatever you have access to. Butter is traditional for the blackening method and gives the best flavor, but olive oil can be swapped in if needed.

Prep ahead: The blackening spice blend can be mixed up well in advance and stored in an airtight jar, making this an even faster weeknight dinner.

Tools: A cast-iron skillet is ideal for blackened fish. Its heat retention gives you that deep, even crust that’s hard to replicate in a regular pan.

Serve with: Napa cabbage slaw, simple lemon kale salad, haricot verts, or air fryer broccoli all pair beautifully. White rice alongside any of those keeps it simple and satisfying.
