Baccala in Tomato Sauce Recipe: Salted Cod Simmered in Rich Italian Tradition

This traditional Italian dish brings the flavors of salted cod to life in a rich tomato sauce. I’ve refined this method over years to honor its authentic roots.

The key is proper preparation of the baccala through soaking, then gently simmering it in a sauce that’s both savory and aromatic. The result is a dish that’s hearty yet balanced.

Ingredients for Baccala in Tomato Sauce

Traditional Italian pantry staples meet carefully prepared salted cod for authentic flavor depth.

The salted cod is non-negotiable here. Look for thick, boneless fillets at specialty Italian markets or Whole Foods—avoid pre-cut pieces as they can be dry. Soaking is critical: change the water 3-4 times over 24-48 hours to remove excess salt. The San Marzano tomatoes should be DOP-certified for authentic sweetness and low acidity.

No white wine? Dry vermouth or additional tomato sauce works in a pinch. For a richer sauce, stir in 1 tbsp of capers with the olives. Dried oregano can be swapped for fresh at triple the amount. If San Marzano tomatoes aren’t available, high-quality canned crushed tomatoes from Muir Glen are a solid substitute.

The soaked cod keeps in the fridge for 24 hours before cooking. Leftovers taste even better the next day and store well for 3-4 days. Freeze the sauce separately for up to 3 months—just add fresh cod when reheating.

Step-by-Step Instructions for Baccala in Tomato Sauce

Master the technique of transforming salted cod into a rich, aromatic dish with Italian flair.

Step 1: Prepare the Salted Cod Properly

Begin by ensuring the 1.5 lb Salted Cod has been soaked overnight to remove excess salt. Drain and rinse the cod, then cut it into 2-inch pieces. Pat the pieces dry with paper towels to remove excess moisture, which helps the fish absorb flavors without becoming watery.

This preparation step is crucial—properly desalted cod ensures the final dish isn’t overwhelmingly salty. The texture should be firm but not rock-hard after soaking.

Step 2: Build the Aromatic Sauce Base

In a large, heavy-bottomed pot, heat ¼ cup of the Extra-Virgin Olive Oil over medium heat. Add the finely diced Yellow Onion and cook for 5-6 minutes until translucent and just beginning to caramelize at the edges. Stir in the 4 minced Garlic Cloves and cook for 30 seconds until fragrant but not browned.

Add the 2 tbsp Tomato Paste and cook for 2 minutes, stirring constantly, until it deepens in color to a rich brick red. This step develops the umami foundation of your sauce. Pour in the ½ cup Dry White Wine and simmer for 3 minutes to reduce slightly.

Step 3: Simmer with Tomatoes and Aromatics

Stir in the 2 cups San Marzano Tomatoes (crushed by hand), 1 tsp Dried Oregano, ½ tsp Red Pepper Flakes, 2 Bay Leaves, ½ tsp Freshly Ground Black Pepper, and ½ cup Green Olives. Bring to a gentle simmer and cook for 15 minutes, allowing the flavors to meld together.

The tomatoes should break down into a thick, rustic sauce. The olives add a briny contrast that balances the richness of the cod. Taste and adjust seasoning with 1 tsp Kosher Salt if needed, remembering that the cod and olives already contribute saltiness.

Step 4: Poach the Cod in the Sauce

Gently add the prepared Salted Cod pieces to the simmering sauce. The liquid should just cover the fish—if it doesn’t, add a splash of water. Reduce heat to low and poach for 8-10 minutes, until the cod is opaque and flakes easily with a fork.

Avoid boiling, as this will break up the delicate fish. The cod should be tender but still hold its shape. Spoon some of the sauce over the fish occasionally to ensure even cooking and flavor absorption.

Step 5: Finish and Garnish

Discard the Bay Leaves. Drizzle with the remaining ¼ cup Extra-Virgin Olive Oil and sprinkle with the ¼ cup chopped Fresh Flat-Leaf Parsley. Let the dish rest for 5 minutes off the heat to allow the flavors to fully harmonize.

The final dish should have a vibrant red sauce with visible olive pieces and a glossy finish from the olive oil. The cod should be moist and flaky, perfectly complementing the robust, aromatic tomato base. Serve warm with crusty bread to soak up the sauce.

Troubleshooting Perfect Results

Sauce Too Watery

If your tomato sauce is thin, simmer uncovered for an additional 10-15 minutes to reduce. I find that crushing the San Marzano Tomatoes by hand creates a thicker texture than blended tomatoes. A pinch of tomato paste can also help thicken it naturally. 💡

Cod Too Salty

This usually means the Salted Cod wasn’t soaked long enough. If you detect excess salt after the first taste, soak the pieces in cold water for an additional 2-3 hours, changing the water once. Avoid adding salt to the sauce until you taste the fish.

If the dish is already cooked, serve with extra sauce and crusty bread to balance the saltiness.

Cod Falls Apart

This happens when the sauce boils or the fish is overcooked. Keep the heat at a gentle simmer—low heat is key. The cod should poach for only 8-10 minutes. Use a wide, shallow pot so the pieces can lie flat without overlapping.

Sauce Too Acidic

A pinch of sugar (½ tsp) balances acidity without sweetening the dish. I also recommend using DOP-certified San Marzano Tomatoes, which are naturally sweeter. If needed, a splash of heavy cream can mellow the sauce beautifully. 🔥

Flavor Seems Flat

Boost depth by adding 1 tbsp capers or a splash of balsamic vinegar. Fresh herbs like basil or more Fresh Flat-Leaf Parsley brighten the dish.
