Frozen Cod vs. Salted Cod
Let's be honest: frozen cod and desalted salted cod are different products. Both are cod (Gadus morhua), but the preservation process radically changes the culinary result.
| Characteristic | Frozen Cod | Desalted Salted Cod |
|---|---|---|
| Texture | Softer, can release water | More gelatinous, firm, dense |
| Flavor | More neutral, mild | More intense, cured flavor |
| Gelatin | Less gelatin | More gelatin (key for sauces) |
| Price | €8-15/kg | €18-45/kg depending on cut |
| Preparation | Thaw (8-12h fridge) | Ready to cook |
| Best Recipes | Baked, in sauce, stewed, battered | Pil pil, confit, grilled, green sauce |
Frozen cod works well in recipes with a potent sauce that compensates for its more neutral flavor. For recipes where cod is the main star (pil pil, grilled), desalted salted cod is far superior.
How to Thaw Cod Correctly
Thawing is the most important step. If you do it wrong, the cod releases water and becomes dry and fibrous.
Correct Method: In the Fridge
- Take the cod out of the freezer the night before (8-12 hours prior).
- Place it on a deep plate covered with plastic wrap or in a sealed container.
- Let it thaw slowly in the refrigerator.
- Before cooking: remove from the container, pat VERY dry with paper towels (several times). Excess water is the enemy.
Emergency Method: Under Cold Water
If you forgot to take it out: place it in its sealed packaging under cold running water for 30-60 minutes. Never use hot water (it cooks the outside while the inside remains frozen).
What You Should NEVER Do
- Thaw at room temperature: risk of bacteria on the outer surface while the inside is still frozen.
- Thaw in the microwave: cooks parts of the fish unevenly.
- Cook directly from frozen: the outside cooks, the inside remains raw and releases water.
6 Recipes That Work with Frozen Cod
1. Baked Frozen Cod with Potatoes
The easiest and most rewarding recipe. The oven sauce compensates for potential dryness.
- Thaw and pat very dry. Season with salt and pepper.
- Layer thin potatoes + onion + bell pepper in a baking dish. Drizzle generously with oil.
- Bake vegetables for 15 min at 200°C. Place cod on top.
- Drizzle with white wine. Bake for another 15-18 minutes.
2. Frozen Cod in Tomato Sauce
Tomato sauce provides the moisture and flavor that frozen cod needs.
- Prepare a sofrito with onion + garlic + grated fresh tomato (20 min).
- Place thawed and dried cod fillets on top of the sauce.
- Cover and cook over low heat for 12-15 minutes.
3. Battered Frozen Cod
The batter protects the fish from heat and traps moisture inside. See full battering technique.
- Thaw, pat dry, cut into pieces. Season with salt and pepper.
- Dredge in flour, then in beaten egg (or beer batter).
- Fry in oil at 180°C, 3-4 minutes per side.
4. Gratinated Frozen Cod
A gratin topping (béchamel, aioli, or cheese) seals in moisture. See 4 gratinated cod recipes.
5. Frozen Cod with Chickpeas (Stew)
In a long stew, frozen cod integrates well because it absorbs the broth's flavors. See stew recipe. Add cod during the last 12 minutes.
6. Frozen Cod in an Air Fryer
The air fryer quickly sears the outside, which helps retain internal moisture. See air fryer cod recipes. The trick: obsessively pat the cod dry before putting it in the air fryer.

Recipes Where NOT to Use Frozen Cod
These recipes require the gelatin and texture of desalted salted cod. With frozen, they simply don't work the same way:
- Bacalao al pil pil: needs the gelatin from salted cod to emulsify the sauce.
- Confit cod: frozen cod lacks the necessary density.
- Grilled cod (alone): without sauce, frozen cod tastes bland.
- Cod with onions (Bacalao encebollado): works, but the result is far inferior to desalted cod.
For these recipes, it's worth investing in quality desalted salted cod.
Frequently Asked Questions
Is frozen cod healthy?
Yes, nutritionally it is almost identical to fresh cod: high in protein, low in fat, rich in omega-3s and B vitamins. Freezing preserves nutrients well.
How long can I keep cod in the freezer?
If well-packaged (airtight), up to 6 months without significant quality loss. Beyond 6 months, it starts to lose texture and flavor (freezer burn).
Can cod be refrozen?
It is not recommended. Each freezing-thawing cycle breaks down more muscle fibers, worsening the texture. If you thawed too much, cook it all and then freeze it cooked.
Does desalted cod from online stores arrive frozen?
Our premium desalted cod travels in a cold chain (refrigerated, not frozen). It stays fresh during shipping and arrives ready to cook or to freeze yourself if you prefer.
