Aldi is one of the most popular chains for buying fish in Spain — aggressive pricing, efficient logistics, and various cod formats available all year round. But what kind of cod are you actually buying? We'll tell you what Aldi doesn't clarify on the label, how much each cut costs in 2026, and when it makes sense to upgrade to artisan cod.
What cod does Aldi sell in 2026?
The 4 most common cod references at Aldi:
- Frozen cod pieces: €6-8/kg. Ideal for stews, hearty soups, and rice dishes. Already desalted. Boneless, but the texture is slightly softer than artisan salted cod after rehydration.
- Vacuum-packed desalted cod: €14-18/kg. Desalted loins, ready to cook. This is usually the best-seller for daily use.
- Frozen cod loins: €12-15/kg. Large pieces, unsalted (just frozen). For baking or frying.
- Occasionally salted cod: €11-14/kg. Whole salted pieces, for you to desalinate. Only available during peak season.
Each Aldi store may vary. Pre-Christmas and pre-Easter periods usually add 1-2 temporary premium references ("Deluxe" brand) which can reach €22-28/kg.
Real quality of Aldi cod: the good and the average
What's good
- Correct labeling: when it says "Gadus morhua," it is. Aldi usually complies with traceability regulations.
- Unbeatable price for frozen cod: €6-8/kg for pieces is hard to beat for daily use.
- Year-round availability: doesn't run out of stock like some fishmongers.
- Correct packaging: well-sealed vacuum pack in most desalted references.
What's not premium
- Fast curing: 7-10 days in industrial brine (vs 20-25 days artisan dry salting). Result: less concentrated flavor.
- Variable origin: North Sea cod (Norway, UK, Denmark) depending on the season. Rarely from Iceland.
- Less natural gelatin: industrial cod releases less collagen when cooked. Noticeable in pil-pil.
- Softer desalted texture: accelerated rehydration results in less firm flesh than a well-desalted artisan cod.
Aldi vs Mercadona vs Lidl: real comparison 2026
Comparison of equivalent products (vacuum-packed desalted loin, 400-500g):
- Aldi: €14-16/kg. Origin Norway / North Sea. Fast desalted.
- Mercadona: €16-20/kg (Hacendado brand). Origin Norway / Iceland depending on the season. A bit more variety of cuts.
- Lidl: €15-18/kg. Similar origin to Aldi. Better for frozen.
- Online artisan: €24-30/kg. Traced Icelandic origin. Curing 20-25 days.

Which recipes work well with Aldi cod (and which don't)
Works perfectly
- Lenten stew with chickpeas and spinach
- Cod croquettes
- Fritters / pancakes
- Potato salad with cod
- Cod rice with vegetables
- Cod stew with potatoes
Not recommended
- Pil-pil: needs gelatin, which industrial cod doesn't have enough of
- Baked alone (baked cod with potatoes as the main dish): falls flat
- Pan-fried with just oil: without strong seasoning, it tastes bland
- Traditional ajoarriero cod: better with artisan salted cod
When to upgrade to artisan cod
Simple criterion: if cod is the star of the dish, buy artisan. If it's just another ingredient, Aldi works.
The jump from €14/kg (Aldi) to €24-30/kg (artisan) is an extra €10-16 per kg. For a dinner for 4 people (800g), that's an additional €8-13 — not much for an important recipe. For daily use, Aldi covers it well.
If you want to try the difference without commitment, in our selection of artisan desalted cod we have snout, nape, and shredded cod from Iceland with refrigerated 24-48h delivery.
Practical tips when buying cod at Aldi
- Read the label. If "Gadus morhua" appears, it's real cod. If it says "white fish," be careful.
- Look at the country of origin. Norway and Iceland are better than the United Kingdom or Denmark (sea temperatures).
- Packaging date: the more recent, the better the texture when cooked.
- Intact vacuum packaging: reject if the seal is bloated or perforated.
- Buy by kg, not by piece: comparing prices is faster.

Conclusion: shop at Aldi with discernment
Aldi offers decent and well-priced cod for everyday use. Frozen pieces for stews, desalted loins for daily recipes, and that's it. Don't expect premium quality for €14/kg.
For the five or six times a year you want to make a true pil-pil or a baked cod that's the star, buy artisan. The extra cost is minimal per diner and the difference is noticeable in every bite.
Want to try it? Start with a loin or a snout from our artisan selection from €18.90. Refrigerated shipping throughout Spain.
