Step-by-Step

Guide to Making Seared Cod with Tomato Basil Sauce

1. Prepare the Cod

Pat the cod fillets dry with paper towels. Removing excess moisture helps create a beautiful golden sear.
Season each fillet with salt, black pepper, garlic powder, paprika, and lemon juice. Let the fish rest for 5 minutes while you prepare your pan.

2. Heat Your Pan

Place a large skillet over medium-high heat and add olive oil and butter.
The butter gives richness, while the oil prevents burning.

3. Sear the Cod

Once the skillet is hot, gently place the cod fillets into the pan.
Cook without moving them for 3–4 minutes—this allows a golden crust to form.
Flip carefully and cook for another 3–4 minutes until the fish is firm, opaque, and flaky.
Remove the cod from the pan and set it aside on a warm plate.

4. Build the Sauce

In the same skillet, add a little more olive oil if needed.
Add onions and sauté until softened and translucent.
Stir in the garlic and cook for 30 seconds until fragrant—avoid burning.

5. Add Tomatoes

Add cherry tomatoes and cook until they begin to burst and release their juices.
Stir in crushed tomatoes for body and depth.

6. Season the Sauce

Add salt, black pepper, red pepper flakes, dry oregano, and sugar.
Let the sauce simmer gently for 8–10 minutes so the flavors meld and the tomatoes soften.

7. Add Basil

Turn off the heat and stir in chopped basil and balsamic vinegar.
Fresh basil releases its aroma beautifully when added at the end.

8. Plate the Dish

Spoon a generous layer of tomato basil sauce onto a plate.
Place a seared cod fillet on top.
Add extra basil leaves for garnish.

The result? A beautifully balanced seafood dish that’s both rustic and refined.

Additional Tips

1. Dry the Fish Well

Dry fish = better sear.

2. Don’t Overcook Cod

Fish should be just opaque and flaky.
Overcooking leads to dryness.

3. Balance the Sauce

If tomatoes taste too acidic:

Add ½ teaspoon more sugar
Add a splash of balsamic vinegar
Add a touch of butter at the end

4. Use Fresh Basil

Dried basil doesn’t offer the same brightness.
Always add fresh herbs at the end.

5. Choose Good Olive Oil

A high-quality olive oil enhances Mediterranean flavors.
