In summary: Cod kokotxas are one of the most coveted parts of the fish, and finding them at Lidl can be a rare discovery. However, their availability is limited and they are usually sold frozen. We explain what to expect, at what price, and when it is worth going to a fishmonger or specialized store to get superior quality kokotxas.

What are cod kokotxas?
Kokotxas (also called kokotxas in Basque) are the fleshy part located on the lower jaw of the cod, between the head and the throat. It is a small piece — each cod only has two — which makes it a scarce and, therefore, highly valued product.
Why are they a delicacy? The kokotxa has a unique composition that differentiates it from any other part of the fish:
- High concentration of natural gelatin: this gelatin is responsible for kokotxas being able to naturally bind sauces, as in the famous pil-pil. No other fish cut emulsifies like this.
- Inimitable texture: soft, unctuous, almost creamy when cooked correctly. It melts in the mouth with a delicacy that is more reminiscent of a hours-long stew than a fish.
- Intense and clean flavor: it concentrates the flavor of cod more intensely than the loin, with a natural hint of sweetness.
- Culinary versatility: they work in pil-pil, in green sauce, breaded, grilled, or confit. Each technique brings out a different nuance.
In Basque gastronomy, kokotxas are a revered product. A good plate of kokotxas al pil-pil is considered one of the great milestones of Spanish cuisine, and Michelin-starred restaurants treat them as a luxury ingredient.
Precisely because of their scarcity — two pieces per fish — cod kokotxas will never be a cheap product. Each kilogram requires processing dozens of cod, which explains their high price compared to loins or flakes.
Cod kokotxas at Lidl: availability and price
This is where we have to be honest: cod kokotxas are not a regular product at Lidl. Unlike cod loins or flakes that we find permanently, kokotxas appear sporadically and almost always in frozen form.
When Lidl includes kokotxas in its assortment, they usually appear as follows:
- Format: bag of frozen kokotxas, usually between 300g and 500g
- Origin: generally North Atlantic cod (Norway or Iceland)
- Approximate price: between €8.99 and €14.99 per bag, which is equivalent to about €25-35/kg
- Availability: themed fish weeks, Easter, or specific promotions
It is important to note that Lidl does not have cod kokotxas in its permanent assortment. If you go looking for them specifically, it is likely that you will come back empty-handed most of the time. Checking the weekly Lidl flyer before going is the best strategy.
When they do appear, demand is usually high: kokotxas are a niche product with a loyal audience that actively seeks them out. It is not uncommon for them to sell out on the first day of the promotion, especially in areas with a Basque or northern Spanish culinary tradition.
Comparison table: Lidl vs fishmonger vs online specialist
| Characteristic | Lidl (frozen) | Traditional fishmonger | Online specialist |
|---|---|---|---|
| Price per kg | 25-35 € | 35-55 € | 40-65 € |
| State | Frozen | Fresh / thawed | Fresh or premium frozen |
| Origin | North Atlantic (generic) | Variable according to supplier | Iceland / Norway (traceability) |
| Piece size | Variable, medium caliber | To choose | Selected by caliber |
| Availability | Sporadic | According to season | On demand, 24-48h delivery |
| Gelatin for pil-pil | Medium (freezing reduces) | High (if fresh) | High (fresh) / Medium (frozen) |
| Ideal for | Breaded, green sauce | Pil-pil, green sauce | Pil-pil, haute cuisine |
The table reveals something interesting: Lidl's price is attractive, but the availability and state of the product (frozen) limit its use in certain preparations, especially in pil-pil, where fresh gelatin makes all the difference.
Fresh vs frozen kokotxas: real differences
This is a crucial point and deserves a detailed explanation, because the difference between fresh and frozen kokotxas is not just about texture — it directly affects the outcome of your recipes.
Fresh kokotxas
- Intact gelatin: the natural gelatin of the fish has not been altered by the freezing-thawing process. This is fundamental for pil-pil, where emulsification depends on this gelatin.
- Superior texture: firmer to the touch, with a consistency that remains during cooking.
- More pronounced flavor: the extreme cold of freezing can attenuate nuances of flavor that fresh kokotxas retain.
- Limited shelf life: 2-3 days in the refrigerator at most, which requires planning.
Frozen kokotxas
- Partially degraded gelatin: ice crystals break down cell structures, releasing water and reducing emulsifying capacity. In pil-pil, this can result in a sauce that does not bind correctly.
- Convenience: they keep for months in the freezer, allowing you to use them whenever you want.
- Lower price: usually 20-30% cheaper than fresh ones.
- Work well breaded: in preparations where gelatin is not the protagonist (breaded, in green sauce with flour), frozen ones give a perfectly acceptable result.
Practical tip: if you buy frozen kokotxas at Lidl and want to make pil-pil, thaw them slowly in the refrigerator for 24 hours (never in the microwave) and dry them very well with kitchen paper before cooking. It will not be the same as with fresh ones, but you will greatly improve the result compared to rapid thawing.
Classic recipe: kokotxas al pil-pil
Pil-pil is the preparation that best honors cod kokotxas. Here is the traditional Basque recipe, simplified but respecting the technical keys:
Ingredients (2 people)
- 300 g of cod kokotxas (fresh, ideally)
- 200 ml of mild extra virgin olive oil
- 4 cloves of garlic
- 1 dried chili pepper (optional)
- Salt
Preparation
- Temper the oil: in an earthenware casserole or large frying pan, heat the oil over low heat with the sliced garlic. Remove the garlic when golden (not burnt).
- Cook the kokotxas: with the oil at a low temperature (60-70 °C), place the kokotxas skin-side up. Cook for 3-4 minutes without touching.
- Flip them over: carefully turn the kokotxas. Cook for another 3-4 minutes.
- Bind the sauce: remove the casserole from the heat and move it with constant circular movements (the famous "swinging"). The gelatin from the kokotxas will emulsify with the oil, creating a white, silky sauce.
- Patience: if the sauce doesn't bind, put it back on very low heat for a few seconds and remove. Repeat the swinging motion. The key is temperature: not too hot (it curdles) nor too cold (it doesn't emulsify).
The result, when it works, is magical: tender kokotxas wrapped in a velvety sauce that only needs good bread for dipping.

Where to buy quality cod kokotxas
If kokotxas have won you over (or you want them to), these are the best options depending on your situation:
To try without spending too much
Frozen kokotxas from Lidl (when they have them) or any supermarket are a reasonable entry point. Prepare them breaded or in green sauce, where freezing doesn't penalize as much. This way, you'll discover if this product is for you without making a large investment.
For authentic pil-pil
You need fresh kokotxas, without exception. A good fishmonger with daily produce is your best option. Ask them to separate them for you — they are a product that flies, especially on Fridays and Saturdays. In Barcelona, the Mercat del Ninot and other municipal markets are excellent places to find them.
For maximum quality without leaving home
Specialized online stores offer kokotxas selected by size, with traced origin and refrigerated delivery in 24-48 hours. In our cod section you can find different presentations of premium cod, including the most select pieces.
The key is to adapt the purchase to the use: not all recipes demand premium kokotxas, just as not all dinners demand a reserve wine. But when the occasion calls for it, the difference between quality fresh kokotxas and frozen supermarket ones is abysmal.

Conclusion
Cod kokotxas at Lidl are a find when they appear: a gourmet product at a supermarket price. For breaded dishes and sauces with flour, they are perfectly adequate. But if you aspire to the textbook pil-pil — the one that emulsifies only with the fish gelatin and the rocking of the pan — you will need fresh kokotxas from a fishmonger or a specialist.
In any case, that Lidl offers cod kokotxas (even if sporadically) is good news: it brings a traditionally exclusive product closer to a wider audience. And that, for cod lovers, is always positive.
