Storage & Freezing Tips

  • Refrigerator: Store leftovers in an airtight glass container for up to 2 days.
  • Reheating: Warm gently in a skillet on medium-low heat with a lid to keep the fish tender. Avoid microwaving to prevent rubbery texture.
  • Freezing: We do not recommend freezing cooked fish as it degrades the texture.

Frequently Asked Questions

Ensure your baking dish is lightly oiled or lined with parchment paper, and make sure the oven is fully preheated before cooking.

Can I make this recipe with frozen fish?▼
