How to Make Pan-Seared Mediterranean Cod in Tomato Basil Sauce Recipe
Step 1: Prepare and Season the Cod
Start by patting your cod fillets dry with a paper towel to ensure a beautiful sear. Season each fillet generously with salt and pepper on both sides. This simple step is crucial because it brings out the natural flavors and helps create that golden crust that makes pan-seared fish so irresistible.
Step 2: Pan-Sear the Cod
Heat one tablespoon of olive oil in a large skillet over medium-high heat until shimmering. Carefully place the cod fillets in the pan, cooking for 2 to 3 minutes per side, or until each side is a gorgeous golden-brown color and the fish is nearly cooked through. Remove the fillets from the skillet and set aside to keep warm. This technique locks in moisture and builds flavor, laying the perfect foundation for the sauce.
Step 3: Sauté Aromatics
In the same skillet, add the remaining tablespoon of olive oil. Toss in the chopped onion and sauté for about 3 to 4 minutes until soft and translucent—this transforms the onion into a sweet, savory base. Following this, add the minced garlic and cook for just 30 seconds, enough to release its fragrance without burning.
Step 4: Build the Tomato Basil Sauce
Stir in the diced tomatoes with their juice, tomato paste, crushed red pepper flakes if you’re adding spice, oregano, salt, and black pepper. Bring the mixture to a gentle simmer, letting it cook for 5 to 6 minutes while stirring occasionally. You’ll notice the sauce thickening slightly and the flavors melding into a rich, comforting sauce.
Step 5: Finish with Basil and Cod Simmer
Freshly chopped basil goes in now, infusing the sauce with an herbal brightness. Nestle the cod fillets back into the skillet, nestling them gently into the sauce and spooning a little over each fillet. Cover and allow everything to simmer together for 4 to 5 minutes. This final step finishes cooking the fish through and lets the flavors develop beautifully, resulting in a tender, flaky cod that tastes like a Mediterranean dream.

Garnishes
To truly elevate the presentation and flavor, serve the cod with fresh lemon wedges for squeezing over the top and a sprinkle of extra chopped basil.

Creative Ways to Present
If you want to impress your guests or family, serve the cod over a colorful Mediterranean grain salad or atop creamy polenta.

Make Ahead and Storage
Storing Leftovers
Leftover cod with tomato basil sauce should be transferred to an airtight container and refrigerated within two hours of cooking. It keeps well for up to 3 days, giving you a convenient, flavorful meal on demand. Just be sure to gently reheat to avoid drying out the delicate fish.
Freezing
This dish freezes reasonably well, though for best texture, freeze the sauce separately from the fish if possible. Store both in airtight containers or heavy-duty freezer bags for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating gently on the stovetop.
Reheating
Reheat leftovers slowly over low heat in a skillet or in the microwave at short intervals to prevent the cod from becoming tough. Adding a splash of water or broth to the sauce can refresh it nicely during reheating. Always avoid overheating as cod is best enjoyed tender and flaky.
