While the potatoes roast, place the cod fillets on a shallow baking tray. Sprinkle with Cajun spice mix, salt, and pepper. Rub the spices into the fillets, then brush with olive oil. - Flip the potatoes:

Tips
- Use skinless cod fillets for a more even cook and easier seasoning.
- For extra crispy wedges, avoid overcrowding the tray.
- A fish spatula works well to lift the cod fillets without breaking them.

Variations and Substitutions
