Story of the Dish
Salt cod became deeply integrated into inland Italian cooking because preserved fish could travel far from the coast and remain available outside the fresh fishing season. In the Marche, baccalà appears in several preparations with potatoes, tomato, onion, wine and herbs. This version keeps the structure simple: properly desalinated fish is paired with potatoes that absorb the cooking liquid while remaining intact, creating a complete main course with a concentrated but not heavy sauce.
The technical priority is to respect two ingredients with very different needs. Potatoes require enough time and liquid to become tender, while salt cod becomes dry and stringy if simmered for too long. The solution is staged cooking. Begin the sauce and potatoes first, then add the fish only when the potatoes are close to ready. This preserves large moist flakes and prevents the dish from turning into a homogeneous mash.
Recipe Information
Servings: 6. Prep time: 30 minutes, plus 24 to 48 hours for desalting if using traditional salt cod. Cooking time: 50 minutes. Total active time: about 1 hour 20 minutes. Difficulty: Intermediate. Course: Main course. Cuisine: Marche, Italy. Best season: fall through spring. Service temperature: hot, after a 5 minute rest.
Ingredients
2 lb (900 g) desalinated salt cod, skin on if possible, cut into 6 large portions
2 lb (900 g) Yukon Gold potatoes, peeled and cut into 1 1/2 inch pieces
1 large yellow onion, thinly sliced
3 garlic cloves, lightly crushed
1/4 cup (60 ml) extra virgin olive oil
3/4 cup (180 ml) dry white wine
2 cups (480 ml) crushed peeled tomatoes
1 tbsp tomato paste
1 1/2 cups (360 ml) light fish stock or water, as needed
2 tbsp chopped Italian parsley
1 small rosemary sprig
1/2 tsp freshly ground black pepper
Fine sea salt only as needed after tasting
1 tbsp chopped parsley and 1 tbsp extra virgin olive oil for finishing
Step-by-Step Preparation
If starting with dry salted baccalà, soak it in cold water in the refrigerator for 24 to 48 hours, changing the water every 8 hours. Thick pieces may require the longer time. Taste a tiny cooked trimming before seasoning the recipe; desalting levels vary dramatically. Pat the fish dry and check carefully for pin bones before cutting it into large portions.
Heat the olive oil in a wide heavy casserole over medium heat. Add the sliced onion and cook for 7 to 8 minutes until soft and translucent but not deeply browned. Add garlic and rosemary and cook for 1 minute. Stir in tomato paste and cook for another minute so it loses its raw flavor and begins to caramelize lightly on the bottom of the pan.
Pour in the white wine and simmer for 3 to 4 minutes, scraping the base of the casserole. Reduce by about half. Add the crushed tomatoes and 1 cup of stock. Bring to a gentle simmer and cook uncovered for 8 minutes. This creates a seasoned base before the potatoes enter, so they absorb flavor rather than dilute the sauce.
Add the potatoes and black pepper. Stir once to coat, partially cover and simmer gently for 18 to 22 minutes. Turn the potatoes occasionally but avoid vigorous stirring. They should become about three quarters tender while holding sharp edges. Add small amounts of the remaining stock only if the pan becomes too dry before the potatoes soften.
Nestle the salt cod portions among the potatoes with the skin side down. Spoon a little sauce over the top without completely burying the fish. Cover partially and simmer very gently for 8 to 12 minutes, depending on thickness. Do not boil. The fish is ready when it separates into moist opaque flakes with light pressure.
Remove the lid and assess the sauce. If it is too loose, lift the fish carefully to a warm plate and reduce the potato mixture for 3 to 5 minutes. If it is already concentrated, leave everything in place. Taste the sauce before adding any salt because the baccalà may have released additional salinity during cooking.
Return the fish if removed, scatter with chopped parsley and drizzle with a tablespoon of extra virgin olive oil. Shake the casserole gently instead of stirring. Rest off the heat for 5 minutes so the starch from the potatoes and gelatin from the fish settle into the sauce.
Serve each portion with one piece of baccalà, several potato pieces and enough sauce to coat the plate. Keep the fish intact during transfer. The finished dish should have identifiable components: flaky fish, tender potatoes and a glossy tomato and wine sauce rather than a thick purée.
Professional Technique
Desalting is part of the recipe, not a preliminary inconvenience. The salt concentration inside a thick piece of cod can remain high even when the surface tastes mild. Cold water, refrigeration and repeated changes draw salt gradually without damaging texture. Never attempt to accelerate the process with warm water, which creates food safety risk and can soften the flesh.
The second professional control is the sequence of cooking. Potatoes should be nearly tender before the fish is introduced. Salt cod contains proteins that tighten quickly under prolonged heat, and its large flakes are part of the appeal. A bare simmer is enough. If the sauce needs further reduction, remove the fish and concentrate the liquid separately.
Professional Kitchen Notes
Choose a waxy or medium starch potato rather than a very floury baking potato. Yukon Gold absorbs flavor while retaining its shape. Cut every piece to similar size so the center finishes at the same time. If using very starchy potatoes, rinse them briefly after cutting but do not soak them for a long time, because some surface starch is useful for body.
For advance preparation, cook the tomato base and potatoes to about two thirds doneness, cool quickly and refrigerate. Finish with the baccalà close to service. This preserves the fish texture. Fully cooked leftovers are still enjoyable, but they should be reheated gently because a second hard simmer makes the cod noticeably firmer.
Chef Tips
Desalt thick baccalà patiently in the refrigerator.
Taste before adding salt at every stage.
Use large fish portions so they remain intact.
Cook potatoes before adding the fish.
Maintain a bare simmer after the baccalà enters.
Remove the fish before reducing the sauce if extra concentration is needed.
Common Mistakes
Assuming all purchased baccalà has the same salt level.
Adding raw potatoes and fish at the same time.
Boiling the cod vigorously until it breaks into dry fibers.
Using too much stock and ending with a soup instead of a braise.
Stirring forcefully after the fish is cooked.
Serving and Presentation
Use warm shallow bowls or plates because the dish includes a modest amount of sauce. Place potatoes first and set the baccalà on top with its flakes intact. Spoon the sauce around rather than drowning the fish. A final thread of olive oil and fresh parsley gives brightness without changing the regional character.
Crusty bread is useful for the sauce, but the potatoes already provide substantial starch, so keep other side dishes simple. Bitter greens such as chicory or sautéed chard make a good contrast to the preserved fish and olive oil.
Wine Pairing
Verdicchio dei Castelli di Jesi: its acidity, savory finish and regional identity work naturally with salt cod, tomato and olive oil. Passerina: a lighter fresh option that cleans the palate without overpowering the fish. Rosso Piceno: a light service temperature can work when the tomato component is pronounced and the wine is not heavily tannic.
Storage and Reheating
Refrigerate cooked baccalà, potatoes and sauce together in a covered container for up to 2 days. Cool promptly and avoid repeated temperature cycles. The fish will continue absorbing salt and sauce during storage, so taste again before reheating and do not season automatically.
Reheat in a covered skillet over low heat with 2 to 3 tablespoons of water or unsalted stock. Warm only until the fish is hot in the center, then uncover briefly if the sauce needs concentration. Avoid microwaving at full power because the edges of the cod dry before the potatoes heat evenly.

Approximate per serving: 445 calories; Protein 40 g; Carbohydrates 39 g; Fat 14 g; Saturated Fat 2 g; Fiber 5 g; Sugars 6 g; Sodium 980 mg; Cholesterol 80 mg. Sodium can vary widely according to desalting, so this value is necessarily approximate.
Final Note
The character of this dish comes from patience rather than decoration. Well-desalted fish, potatoes that hold their form and a reduced tomato and wine base create a meal that is substantial without being heavy.
The standard at service is moist cod that opens into broad flakes, potatoes tender through the center and a sauce concentrated enough to cling. If the fish has disintegrated or the sauce is watery, the timing or reduction sequence needs correction.
