Cod in Sauce: 8 Traditional Recipes for Every Occasion
Cod and sauces are a historical combination: the lean meat of Gadus morhua absorbs flavors like no other fish, and its natural collagen thickens sauces, giving them a silky texture impossible to replicate with any other ingredient. These 8 recipes cover the full spectrum — from the minimalism of pil pil to the complexity of Vizcaína — with verified times, proportions, and tricks from real kitchens.
Why cod works so well in sauce
Updated March 2026. After decades working with seafood, we've learned that quality makes all the difference.
Cod has three properties that make it the ideal fish for sauces:
- Collagen: the gelatin released by cod when cooked acts as a natural thickener. It's the basis of pil pil and the reason why cod sauces have that unctuous texture without needing flour or cream.
- Absorption: cod meat — especially if it has been salted and desalted — has a porous structure that absorbs the flavors of the sauce. A cod loin in green sauce tastes like green sauce throughout, not just on the outside.
- Firmness: desalted cod maintains its structure during prolonged cooking. It doesn't fall apart like other white fish. You can cook it for 15-20 minutes in sauce and the flakes will remain defined.
For all recipes in this article, we use desalted cod as a starting point. Desalting is the preliminary step that determines the final result: poorly desalted cod ruins any sauce. If you are unsure about the process, consult our desalting guide.

1. Cod in green sauce
Origin: Basque Country
Green sauce is the mother of fish sauces in Basque cuisine. Olive oil, garlic, flour, fish stock, and fresh parsley — nothing more. The magic lies in the emulsion formed by moving the pot in circular motions (the "vaivén") while the cod's gelatin integrates with the oil.
Ingredients (4 servings)
- 4 desalted cod loins (200 g each)
- 6 cloves garlic, sliced
- 100 ml extra virgin olive oil
- 1 tablespoon flour
- 200 ml fish stock
- 100 ml white wine
- Fresh parsley, chopped (generous amount)
- Chili pepper (optional)
Step-by-step
Sauté sliced garlic in oil over medium heat (3 min). Add flour, stir for 1 min. Pour in white wine and let evaporate for 2 min. Add hot fish stock. Place cod loins skin-side up. Cook over medium-low heat for 12-15 min, moving the pot in circular motions to emulsify the sauce. Add parsley in the last 2 min. Serve immediately.
Key: do not stir with a spoon — move the entire pot. The back-and-forth motion produces the emulsion that binds the sauce. For the complete recipe with photos, visit cod in green sauce.
2. Cod a la Vizcaína
Origin: Biscay, Basque Country
Vizcaína is a red sauce made with dried choricero peppers — not tomatoes, as many people believe. Choricero peppers give it an intense red color, sweet-smoky flavor, and velvety texture. It is a quintessential Christmas dish in the Basque Country.
Ingredients (4 servings)
- 4 desalted cod loins (200 g each)
- 12 dried choricero peppers
- 2 large onions, chopped
- 4 cloves garlic
- 100 ml olive oil
- Day-old bread (2 slices)
- Fish broth
Step-by-step
Soak choricero peppers in hot water for 30 min. Sauté onion and garlic in oil over low heat for 25-30 min (they should be completely sweet). Scrape the flesh from the peppers with a spoon, discarding the skin. Add the pepper flesh and soaked bread to the onion. Blend everything until a fine sauce is obtained. Strain if you want a silkier texture. Cook cod loins in the sauce for 15 min over low heat.
Key: sauté the onion for at least 25 minutes. If the onion isn't sweet, the sauce will be mediocre.
3. Cod al pil pil
Origin: Basque Country
Pil pil is the most respected dish in cod cuisine. Three ingredients (cod, olive oil, garlic) and a technique that requires patience: the emulsion forms with the gelatin released by the desalted cod when confiting in oil at a low temperature.
Ingredients (4 servings)
- 4 desalted cod loins with skin (200 g each)
- 250 ml extra virgin olive oil
- 6 cloves garlic, sliced
- 1-2 dried chili peppers (optional)
Step-by-step
Brown sliced garlic in oil over low heat (3 min). Remove them. Add chili peppers for 30 seconds and remove. Lower the heat to minimum. Place cod loins skin-side up in warm oil (not hot — maximum 70 °C). Confit for 15-20 minutes without the oil bubbling. Remove the cod to a plate. With the pot off the heat, stir the oil in circular motions for 5-10 minutes. The cod's gelatin will emulsify with the oil, forming the pil pil sauce. Return the cod to the pot, cover with the sauce, and serve.
Key: low temperature and patience. If the oil is too hot, the gelatin coagulates instead of emulsifying. And the cod must be desalted — frozen cod doesn't have enough gelatin.
4. Cod in tomato sauce
Origin: Popular Spanish cuisine
The most homemade and comforting dish on the list. Tomato, onion, pepper, and cod. It always works.
Ingredients (4 servings)
- 4 pieces desalted cod (200 g each)
- 1 kg ripe tomatoes (or 400 g canned crushed tomatoes)
- 2 onions, chopped
- 1 green pepper, chopped
- 3 cloves garlic
- 80 ml olive oil
- 1 teaspoon sugar (optional, corrects acidity)
- Salt, pepper, bay leaf
Step-by-step
Sauté onion and pepper in oil for 10 min. Add chopped garlic for 2 min. Incorporate grated or crushed tomatoes. Cook for 20-25 min over medium heat until the sauce thickens and loses its acidity. Adjust salt and add sugar if the tomato is acidic. Submerge cod pieces in the sauce and cook for 12-15 min over low heat.
Key: give the tomato time. A tomato sauce cooked for 20 minutes has a completely different flavor than one cooked for 10 minutes.
5. Cod with samfaina
Origin: Catalonia
Samfaina is the Catalan version of pisto or ratatouille: eggplant, zucchini, pepper, and tomato slowly sautéed. With cod, it's a perfect summer dish.
Ingredients (4 servings)
- 4 desalted cod loins
- 1 large eggplant
- 2 zucchinis
- 2 red peppers
- 4 ripe tomatoes
- 1 onion
- 3 cloves garlic
- 100 ml olive oil
Step-by-step
Dice all vegetables into 1-2 cm cubes. Sauté onion for 5 min, add eggplant for 5 min, peppers for 5 min, zucchini for 3 min, and finally tomato for 10 min. Each vegetable needs its own time. Grill or bake the cod for 6-8 min. Serve over hot samfaina.
Key: cook each vegetable separately at different times. If you add them all together, they will boil instead of sautéing.
6. Cod al Club Ranero
Origin: Bilbao, Basque Country
A variation of green sauce that incorporates asparagus, clams, and peppers. It is the celebration dish of the Gastronomic Society El Club Ranero in Bilbao.
Ingredients (4 servings)
- 4 desalted cod loins
- 200 g clams
- 8 white asparagus spears
- 4 cloves garlic
- 1 chili pepper
- 100 ml olive oil
- 150 ml fish stock
- Chopped parsley
- Hard-boiled eggs (optional)
Step-by-step
Prepare a basic green sauce (garlic, oil, flour, fish stock). Cook the cod for 10 min in the sauce. Add clams and sliced asparagus. Cook for 5 more min until the clams open. Garnish with parsley and, optionally, hard-boiled egg slices.
7. Cod al Ajoarriero
Origin: Navarre / La Rioja
A scramble of flaked cod with tomato, pepper, and egg. Hearty, filling, ideal for winter dinners.
Ingredients (4 servings)
- 400 g desalted cod, flaked
- 4 choricero peppers or 2 red peppers
- 4 ripe tomatoes, grated
- 2 onions, chopped
- 4 cloves garlic
- 4 eggs
- 80 ml olive oil
Step-by-step
Sauté onion and garlic for 10 min. Add chopped pepper for 5 min. Incorporate grated tomato for 10 min. Add flaked cod and cook for 5 min. Beat the eggs and incorporate them off the heat, stirring so they set creamy with the residual heat.
8. Portuguese-style cod
Origin: Portugal
One of the most well-known recipes in Portuguese cuisine. Baked cod over a bed of potatoes, onion, and tomato, with black olives and hard-boiled egg.
Ingredients (4 servings)
- 4 desalted cod loins
- 4 medium potatoes, thinly sliced
- 2 onions, sliced into rings
- 3 tomatoes, sliced
- 1 green pepper, cut into strips
- Black olives
- 4 hard-boiled eggs

Frequently asked questions
Which is the easiest cod in sauce recipe?
Cod in tomato sauce and cod al ajoarriero are the most accessible. They don't require special techniques and are forgiving of errors. Pil pil is the most difficult due to the emulsion.
Which cod cut is best for cooking in sauce?
Loin with skin is the most versatile cut. It works in all 8 recipes, maintains its shape during cooking, and the skin provides gelatin that enriches the sauce. For ajoarriero, flakes are perfect and more economical.
Can I freeze cooked cod in sauce?
Yes. Cod in sauce freezes well for up to 3 months. Freeze in airtight containers with the sauce covering the cod. Thaw in the refrigerator and reheat over low heat. The texture remains reasonably well in water-based sauces (green, tomato, Vizcaína).
How long does cod cook in sauce?
Between 12 and 20 minutes over low heat, depending on the thickness. A 4-5 cm loin needs 15 minutes in hot (not boiling) sauce. The sign that it's ready: the flakes begin to separate when pressed with a finger.
Can I make these recipes with frozen cod?
You can, but the result will be inferior. Frozen cod has less gelatin (key for pil pil and green sauce), more water (dilutes sauces), and a softer texture. If you use it, thaw well, pat dry, and accept that the sauce will need more reduction.
