Bacalao al Pil-Pil
This bacalao al pil pil recipe cooks desalted cod loins slowly in garlic-infused olive oil, then shakes the pan until the fish's own gelatine turns the oil into a pale, silky emulsion sauce. No cream, no flour — just cod, garlic and oil. One serving is about 194 g.
Pil pil is the cooking of the Basque Country, and its name imitates the sound of the sauce bubbling — pil-pil — as the pan is shaken. The dish grew out of the Basque trade in salt cod: desalted cod, cooked gently in garlic oil, releases gelatine from its skin, and shaking the pan turns the oil into a pale emulsion without any thickener. It is the emblem of Basque home cooking — three ingredients, one technique, and a sauce that cannot be bought ready-made.
Pairs well with: Crusty bread and a glass of dry white wine or txakoli

Estimated cost: Medium — about $5–7 per serving at home (salt cod loins and good olive oil) (USD)
A true pil pil is judged by the sauce: pale, glossy and clinging to the spoon.
Execution Methodology & Culinary Technique
Prep Stage: Desalt the Cod and Infuse the Oil
25 Mins active + 24–48 hours passive desalting • Fish Prep
Desalt the cod 24–48 hours ahead: soak the loins in cold water in the fridge, changing the water 3–4 times a day, until a small piece tastes pleasantly salty, not harsh. On the day, pat the loins very dry. Slice the garlic, and pour the oil into a wide, shallow pan or earthenware cazuela — the fish must sit in a single layer.
Maestro Tip: Taste a corner of the cod after desalting: if it still stings with salt, give it another 12 hours and two more water changes.
5 Mins Medium heat, about 160°C (320°F)
Warm the oil over medium heat, add the garlic slices and the chillies, and fry gently until the garlic is pale gold — about 3–4 minutes. Lift the garlic and chillies out with a slotted spoon and set aside; they go back on top at the end.
Pale gold, not brown — brown garlic turns bitter and ruins the sauce.
Done when: Garlic slices evenly pale gold.
12 Mins Low heat, about 70°C (158°F) — the oil should barely tremble
Lay the cod loins skin-side down in the warm oil, in a single layer. Cook gently for 10–12 minutes, turning once halfway, until the fish flakes easily and the flesh reaches 63°C (145°F). Do not let the oil bubble — a rolling boil breaks the gelatine and the sauce will never form.
If the oil starts to bubble, lift the pan off the heat for a minute; patience is the whole technique.
Done when: Flesh opaque, flakes easily, 63°C (145°F) at the thickest point.
8 Mins Low heat, then off the heat
Lift the cod onto a warm plate. Tip the pan gently and shake it in small circles, off the heat, for 5–8 minutes: the oil will slowly turn pale, thick and creamy as the cod's gelatine emulsifies it. If it resists, add a spoonful of the cod's cooking juices and keep shaking. The sauce should coat a spoon like thin mayonnaise.
Keep the pan moving in small, steady circles and never let it get hot again — heat breaks an emulsion.
Done when: Pale, glossy sauce that coats the back of a spoon.
2 Mins Low heat
Slide the cod back into the sauce skin-side down, spoon sauce over the top, and warm through for 1–2 minutes without boiling. Scatter the reserved garlic and chillies over the top, sprinkle with parsley, and serve at once in the cazuela or in warm bowls.
Serve immediately — the emulsion thins as it cools, and reheating it hard will split it.
Done when: Cod hot through, glossy sauce clinging to the fish.
Finishing Touches & Plating
Serve straight from the cazuela, with the cod sitting in its pale emulsion and the fried garlic on top. Put crusty bread on the table — the sauce is too good to leave in the dish.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.
Vitamins & minerals: Vitamin B12 and selenium (cod), vitamin C and vitamin K (parsley), vitamin E (olive oil).
High in protein
About 27 g of protein per serving from the cod, with no added carbohydrate.
Healthy fats from olive oil
The sauce is built on extra-virgin olive oil, rich in monounsaturated fat.
No cream, no flour
The creamy sauce is an emulsion of oil and the cod's own gelatine — nothing is added to thicken it.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Crusty bread
Bread is made for this sauce — it carries the emulsion, which is the whole point of the dish.
Drinks
Txakoli
The light, slightly sparkling Basque white wine cuts through the rich oil and matches the dish's origins.
Vegetables
Piquillo peppers
Sweet roasted piquillo peppers add colour and a gentle sweetness against the garlicky sauce.
Full Menus
As part of a Basque table
Serve after a salad or pintxos, with the cod as the centrepiece of a slow, shared dinner.
Complete menu

Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Do not boil the cod
High heat toughens the fish and breaks the gelatine, so the emulsion never forms and the sauce stays as plain oil. This is general cooking guidance, not medical advice.
Do not add cream to 'fix' the sauce
Cream masks the pil pil flavour and changes the dish into something else — if the emulsion resists, keep shaking with a spoonful of cooking juices instead.
