Types of cod and freezing
| Type | Can it be frozen? | Maximum time |
|---|---|---|
| Fresh cod | ✅ Yes (mandatory for anisakis) | 3-4 months |
| Desalted cod | ✅ Yes, very practical | 2-3 months |
| Salted cod | ⚠️ Not necessary (salt preserves it) | Not recommended |
| Cooked cod | ✅ Yes (with limitations) | 1-2 months |
🛒 Desalted Cod Ready to Use
Avoid the desalting and freezing process: our desalted cod is ready to cook directly. Guaranteed quality.

For fresh or desalted cod:
- Dry thoroughly with paper towels (moisture forms ice crystals that damage the texture)
- Divide into individual or 2-person portions
- Wrap each portion in cling film, removing all air
- Place in an airtight freezer bag, remove air
- Label with date and contents
- Freeze at -18°C or below
Correct thawing
- Ideal method: in the refrigerator for 12-24h (slow, preserves texture)
- Quick method: under cold running water in an airtight bag (2-3h)
- Never: microwave (cooks external proteins), room temperature (bacterial risk)
Impact on quality
Freezing has a minimal impact on cod if done correctly. Muscle fibers are well preserved, and the texture after thawing is almost identical to the fresh product. The main risk is freezer burn: this occurs when the cod is not well wrapped, and the freezer air dehydrates the surface.
For dishes where texture is critical (pil-pil, grilled cod), preferably use unfrozen cod or cod correctly frozen for less than 2 months. For stews and recipes with sauces, freezing does not affect the result.
Frequently asked questions
Does salted cod need to be frozen?
No. High concentrations of salt act as an effective preservative that prevents bacterial and parasitic growth. Salted cod can be stored in a cool, dry place for months or years. Freezing it offers no benefit and can alter the salt.
Can I refreeze cod that has already been frozen?
It is not recommended to refreeze cod that has already been completely thawed: quality deteriorates, and bacterial risk increases. If you thawed more than necessary, cook it that same day and freeze it cooked if you want to preserve it.
