The Ingredients I Use to Bring My Pan-Seared Mediterranean Cod in Tomato Basil Sauce to Life

For the cod:

• 4 evenly sized cod fillets, approximately 6 ounces each.
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper
• 1/2 teaspoon dried oregano
• 2 tablespoons olive oil for searing

For the tomato basil sauce:

• 3 tablespoons extra virgin olive oil
• 1 medium onion, finely diced (about 1 cup)
• 4 cloves garlic, minced
• 1/4 teaspoon red pepper flakes (adjust to taste)
• 1 can (14.5 oz) diced tomatoes
• 1/4 cup dry white wine, like Pinot Grigio or Sauvignon Blanc.
• 1 tablespoon tomato paste
• 1/2 cup fresh basil leaves, roughly chopped, plus additional for garnish
• 1/2 teaspoon dried oregano
• 1/4 cup kalamata olives, pitted and halved
• 2 tablespoons capers, drained
• 1 tablespoon fresh lemon juice
• Salt and freshly ground black pepper to taste

For garnish:

• 2 tablespoons fresh basil, thinly sliced into ribbons
• Lemon wedges for serving
• 2 tablespoons crumbled feta cheese (optional)

Step-by-Step Instructions

Step 1: Prepare the Cod

Begin by patting the cod fillets completely dry with paper towels. This step is crucial for achieving a beautiful sear – excess moisture will cause the fish to steam rather than sear. In a small bowl, combine the salt, pepper, and dried oregano, then evenly season both sides of the cod fillets with this mixture. Let the seasoned fillets rest at room temperature for about 10 minutes while you start the sauce. This brief rest allows the seasonings to penetrate the fish and helps it cook more evenly.

Step 2: Start the Tomato Basil Sauce

Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add the diced onion and sauté for about 3-4 minutes until translucent and softened but not browned. Add the minced garlic and red pepper flakes, cooking for another 30 seconds until fragrant, being careful not to burn the garlic as it can become bitter.

Pour in the white wine and let it simmer for 1-2 minutes, allowing the alcohol to cook off while scraping up any flavorful bits from the bottom of the pan. Add the diced tomatoes (with their juice), tomato paste, dried oregano, and half of the fresh basil. Stir well to combine, then reduce the heat to medium-low and let the sauce simmer for 8-10 minutes, allowing it to reduce slightly and develop deeper flavors.

Step 3: Sear the Cod to Perfection

While the sauce simmers, it’s time to cook the cod. In a separate large non-stick skillet, heat 2 tablespoons of olive oil over medium-high heat until it shimmers but isn’t smoking. Carefully place the cod fillets in the hot pan, presentation side down (usually the side that was the skin side), and cook undisturbed for 3-4 minutes until a golden crust forms.

Using a thin, flexible spatula, gently flip the fillets and cook for an additional 2-3 minutes on the second side, depending on thickness. The cod is done when it flakes easily with a fork and has reached an internal temperature of 145°F (63°C). Be careful not to overcook the fish – even a minute too long can transform perfectly tender cod into a dry disappointment.

Transfer the seared cod to a clean plate and cover loosely with foil to keep warm while you finish the sauce.

Step 4: Finish the Mediterranean Sauce

Return your attention to the simmering tomato sauce. Add the halved kalamata olives, capers, and the remaining fresh basil to the sauce, stirring to incorporate. The olives and capers will add a beautiful briny quality that is characteristic of Mediterranean cuisine. Stir in the fresh lemon juice, which will brighten all the flavors and bring balance to the sauce.

Taste the sauce and adjust the seasoning with additional salt and pepper as needed. Remember that the capers and olives contribute saltiness, so add additional salt sparingly. Let the sauce simmer for another 1-2 minutes to allow these final ingredients to meld together.

Step 5: Combine and Serve

To serve, you have two elegant options. You can either return the seared cod fillets to the skillet with the tomato basil sauce, spooning some sauce over each fillet and allowing them to warm together for a minute before serving. Alternatively, you can pool some of the warm sauce on individual serving plates and place a cod fillet on top of each.

Either way, finish each serving with a sprinkle of the reserved fresh basil ribbons and a few crumbles of feta cheese if using. Place a lemon wedge on each plate for diners to add a final touch of brightness if desired. The contrast of the white fish, red sauce, and green basil creates a visually stunning presentation that promises the Mediterranean flavors to come.

Top Tips for Perfecting Pan-Seared Mediterranean Cod in Tomato Basil Sauce

1. Choose the right cod

Choose thick, firm cod fillets with a translucent look and a clean, ocean-like scent—never a fishy odor. Opt for center-cut pieces with even thickness for the most consistent cooking. If fresh cod isn’t an option, quality frozen fillets are a great alternative—just make sure they’re fully thawed and dried thoroughly before baking.

2. Get the perfect sear

Achieving a perfect sear on cod starts with a hot pan and minimal handling. Along with thoroughly drying the fish, ensure your pan is fully heated before placing the fillets in. You should hear a clear sizzle as the fish hits the surface. Avoid the temptation to move or flip the fish too soon—it will release easily once a golden crust has formed.

3. Don’t overcook the fish

Cod cooks quickly and continues cooking slightly even after you remove it from the heat. It’s done when it just turns opaque and flakes easily with a fork. For most 1-inch-thick fillets, this equates to about 3-4 minutes per side. When in doubt, it’s better to slightly undercook than overcook, as residual heat will continue the cooking process.

4. Build layers of flavor in your sauce

For the most flavorful tomato basil sauce, focus on building layers. Allow the onions to properly soften, let the wine reduce to concentrate its flavor, and give the sauce adequate time to simmer. Adding the olives, capers, and final hit of fresh basil at the end preserves their bright flavors and textural elements.

5. Make-ahead options

The tomato basil sauce can be made up to 3 days ahead and stored in the refrigerator. This actually allows the flavors to develop even further. When ready to serve, simply reheat the sauce and proceed with searing the fish. This makes the final cooking process even quicker.

6. Substitution options:

• Other fish: This recipe works well with halibut, sea bass, or even salmon
• Wine alternatives: Use chicken broth with a splash of white wine vinegar if you prefer not to use alcohol
• Fresh vs. canned tomatoes: In summer, substitute 1.5 pounds of fresh tomatoes, peeled and diced, for an even more vibrant sauce
• Herb variations: Fresh thyme or oregano can complement or replace some of the basil for a different flavor profile
• Heat level: Adjust the red pepper flakes to your preference, or substitute with a pinch of Aleppo pepper for a more complex heat

Storing and Reheating Tips

While Pan-Seared Mediterranean Cod in Tomato Basil Sauce is best enjoyed fresh from the skillet, sometimes leftovers are inevitable. Here’s how to handle them:

Refrigerating:

Store the fish and sauce separately if possible to preserve the texture of the cod. Place cooled leftovers in airtight containers and refrigerate for up to 2 days. The sauce alone will keep well for up to 4 days and actually improves in flavor as it sits.

Freezing (with caution):

The tomato basil sauce freezes beautifully in airtight containers or freezer bags for up to 3 months. However, I don’t recommend freezing the cooked cod, as its delicate texture will deteriorate significantly upon thawing and reheating.

Reheating for best results:

To maintain the cod’s texture when reheating, gentle, low heat is key:

For the sauce: Reheat in a skillet over medium-low heat until just warmed through.

For the fish: Place in a covered oven-safe dish with a tablespoon of water or olive oil and warm in a 275°F (135°C) oven for about 10 minutes, or just until heated through. Alternatively, place on a microwave-safe plate, cover with a damp paper towel, and heat on 50% power in 30-second intervals.

Creative leftover ideas:

If the thought of reheated fish doesn’t appeal to you, consider these alternatives:

• Flake the cold cod and mix it with a bit of the sauce for a Mediterranean-inspired fish salad
• Use both the flaked fish and sauce as a topping for crusty bread to make an open-faced sandwich
• Combine flaked cod with the sauce, add a beaten egg, breadcrumbs, and form into patties for Mediterranean fish cakes

This Pan-Seared Mediterranean Cod in Tomato Basil Sauce has become one of my signature dishes for both casual family dinners and entertaining guests.
