Baccala Sauce Recipe: Salty Cod Simmered With Celery, Vinegar, and Olive Oil

This baccala sauce recipe transforms humble salted cod into a rich, briny condiment that elevates Italian dishes with its deep umami flavor. The process begins with soaking the cod to remove excess salt, then simmering it with celery, vinegar, and olive oil until the texture becomes velvety and aromatic.

What makes this sauce special is how it balances saltiness with acidity, creating a versatile base for pasta, polenta, or crusty bread.

The traditional method involves slow cooking the baccala with vegetables and aromatics, allowing the flavors to meld into a harmonious sauce. Unlike other fish-based condiments, this one relies on the cod’s natural saltiness rather than added seasonings, making it a true taste of Italian coastal cuisine.

The result is a sauce that’s both simple and sophisticated—perfect for those who appreciate the art of preserving and transforming ingredients.

Once prepared, this sauce can be stored in the refrigerator for up to a week, or frozen for longer shelf life. Its rich, salty profile pairs beautifully with creamy polenta, al dente pasta, or even as a topping for grilled vegetables.

The texture is smooth yet substantial, ensuring every spoonful delivers layers of flavor that linger on the palate.

For pescatarians or those looking to explore traditional Italian flavors, this baccala sauce is a game-changer. It’s a testament to how a single ingredient—when treated with care—can become the heart of a meal. Ready to create something extraordinary from something simple? Let’s get started.

Ingredients for baccala sauce

Transform salted cod into a velvety, umami-rich sauce with these ten essential ingredients.

The salted cod is the foundation—opt for fully cured baccala from Italian specialty stores or well-stocked seafood markets. Trader Joe's often carries it pre-cured, but for authenticity, seek out preserved cod from Liguria. The celery and onions should be fresh, not wilting, as they form the aromatic base. If using dried bay leaves, toast them briefly in olive oil before adding for deeper flavor. The vinegar and wine balance the saltiness, so dry, bold varieties work best—avoid sweet or fruity options.

No white wine? Dry vermouth or extra red wine vinegar works in a pinch, though the flavor profile shifts slightly. Substituting celery with fennel or leeks adds complexity but requires adjusting cooking time. For a quicker version, blend the cooked vegetables into a smoother sauce, though traditionalists prefer the rustic texture. The olive oil must be extra-virgin—lower grades will overpower the delicate flavors. If you lack black peppercorns, coarsely ground black pepper at half the amount suffices, though freshly cracked is ideal.

This sauce thickens as it cools, so strain it through a fine-mesh sieve before storing for a silky texture. Keeps up to 1 week in the fridge, sealed under a thin layer of olive oil to preserve freshness. For longer storage, freeze in ice cube trays—thaw and whisk to restore consistency. The sauce intensifies overnight, so reheat gently to maintain its velvety mouthfeel. Pair with creamy polenta or al dente spaghetti for the full Italian experience.

Step-by-step instructions for baccala sauce

Transform salted cod into a rich, aromatic sauce with this traditional method.

Rinse the 1 lb salted cod (baccala) thoroughly under cold running water to remove excess salt. Place it in a large bowl and cover completely with cold water. Let it soak for at least 12 hours, changing the water 3-4 times during this period. This extended soaking removes residual salt and prevents the sauce from becoming overly salty.

After the final water change, drain the cod and pat it dry with paper towels. The texture should be firm but pliable, not rubbery. If the skin remains attached, score it lightly with a sharp knife to help it release during cooking. This preparation ensures the cod absorbs the flavors evenly and breaks down properly in the sauce.

In a large Dutch oven, combine the 1.5 cups extra-virgin olive oil, 4 whole celery stalks (roughly chopped, including stringy parts), and 2 whole yellow onions (roughly chopped). Place the pot over medium-low heat and cook for 15-20 minutes, stirring occasionally, until the vegetables soften and the oil begins to take on a golden hue.

Add the 4 cloves garlic cloves (lightly crushed), 2 whole bay leaves, and 10 whole black peppercorns (lightly crushed). Cook for an additional 3-4 minutes until the garlic is fragrant but not browned. This aromatic base forms the flavor foundation of the sauce, infusing the olive oil with deep, savory notes.

Increase the heat to medium-high and add the 0.5 cup red wine vinegar and 0.5 cup white wine. Bring the mixture to a gentle simmer, then carefully add the prepared salted cod. Reduce the heat to low and cover the pot partially, allowing the sauce to steam gently for 45-60 minutes. The cod should break down into flakes and release its oils into the sauce.

Occasionally spoon the sauce over the cod to ensure even cooking. The sauce should reduce slightly, becoming thick and glossy. If it appears too thin, uncover the pot and simmer for an additional 10-15 minutes to achieve the desired consistency. The acidity from the vinegar and wine tenderizes the cod while balancing its saltiness.

Remove the cod from the pot and transfer it to a plate, leaving the sauce behind. Strain the sauce through a fine-mesh sieve into a clean saucepan, pressing gently on the solids to extract all the flavorful liquid. Discard the solids. Return the strained sauce to medium-low heat and add the 1 tsp salt, adjusting to taste if needed.

Simmer the sauce uncovered for 5-7 minutes to deepen its flavor and reduce it to a rich, velvety consistency. The sauce should coat the back of a spoon and have a glossy sheen. Taste and adjust the seasoning, adding a pinch more salt or a splash of vinegar if necessary. This final step ensures the sauce is perfectly balanced and ready to serve.

Slice the cod into ¼-inch thick pieces and return it to the sauce, allowing it to absorb the flavors once more. Serve the baccala sauce warm or at room temperature, spooned over crusty bread, polenta, or as a condiment for grilled meats. The sauce keeps well in an airtight container in the refrigerator for up to 5 days, or it can be frozen for up to 3 months.

For best results, reheat the sauce gently over low heat, stirring occasionally, until warmed through. The sauce should retain its rich texture and deep, savory flavor. This traditional preparation transforms simple ingredients into a dish that highlights the unique character of salted cod.

Wine and beer pairings for these flavors

White Wine Pairings

Dry Italian whites like Vermentino or Pinot Grigio complement this sauce beautifully—their crisp acidity cuts through the richness while enhancing the briny notes of the cod. I love a chilled Vermentino from Sardinia with its citrusy brightness, or a Pinot Grigio from Alto Adige for a more mineral-driven contrast.

Avoid anything too oaky or buttery, as those flavors will clash with the sauce's delicate balance. 🍷

Red Wine Options

For those who prefer red, a light-bodied Chianti or Sangiovese works surprisingly well. The sauce's acidity stands up to the wine's tannins, creating a harmonious pairing. Look for a Chianti Classico with bright cherry notes that won't overpower the cod's umami.

Serve it slightly cooler than room temperature to preserve its freshness alongside the sauce.

Beer Pairings

A crisp Italian lager like Peroni or Moretti is my go-to beer pairing—its clean, effervescent quality refreshes the palate between bites. For craft beer lovers, a Belgian witbier with its peppery, citrus notes provides an interesting contrast to the sauce's saltiness.

Avoid heavy stouts or IPAs, as their bold flavors will dominate the dish. 🍺

Unexpected Pairings

For a non-alcoholic option, try a sparkling water with a squeeze of lemon—its effervescence cleanses the palate beautifully. If you're serving the sauce with polenta, a dry sparkling wine like Prosecco adds a festive touch without overpowering the flavors.

The key is balancing the sauce's saltiness with something light and refreshing.

Regional Wine Traditions

In Northern Italy, this sauce is often paired with Lambrusco, a lightly sparkling red wine from Emilia-Romagna. Its fruity notes and slight effervescence make it a perfect match for baccala dishes.

For a Sicilian twist, try a Nero d'Avola—its bold yet balanced profile stands up to the sauce's intensity. Each region's wine reflects its local terroir and complements the dish uniquely.
