This one-pan Mediterranean cod builds a bright tomato and caper sauce right over the savory fond left from searing the fish to a dark golden crust. You capture every bit of roasted garlic and white wine flavor without facing a sink full of dirty skillets.

Why Searing First Builds a Better Tomato Sauce
Most fish recipes skip the sear. That is a mistake. Boiling white fish from raw leaves it rubbery and bland, but searing the cod in hot olive oil first creates a layer of browned flavor that deglazes perfectly into the wine and blistered tomatoes later. Always start with thoroughly dried fillets so the fish actually browns instead of steaming in its own juices.
How to Sear and Simmer the Cod
Dry and sear the fillets. Dry the fillets completely. Season them aggressively. I always press a fresh paper towel into the fish twice because surface moisture is the absolute enemy of a good sear. Warm a tablespoon of olive oil over medium-high heat, sear the cod for three to four minutes until it releases easily, give it one minute on the second side, and move it to a plate.
Blister the cherry tomatoes. Lower the heat. Add the remaining oil. The pan is still hot enough that the cherry tomatoes will hiss and begin to soften almost immediately as you stir them. Cook them for five to seven minutes until the skins burst and release their juices into the skillet.
Deglaze and reduce. Toss in the garlic. Add the red pepper flakes. Cook for just one minute until the garlic softens without turning brown and bitter. Pour in the white wine and scrape up all the savory bits from the bottom with a wooden spoon as the liquid bubbles and reduces by half, about two to three minutes. Stir in the drained capers, sugar, lemon zest, and juice.
Finish the fish. Return the cod to the skillet. Pour the resting juices over the fillets. Spoon the bubbling tomato sauce over the top and allow the fish to simmer gently for two to three minutes, or until it reaches an internal temperature of 145°F (63°C). Pull the pan from the heat and scatter the torn basil across the top.
Serving the Cod
Bring the skillet to the table. Serve immediately. I prefer to plate this straight from the pan so the fillets stay warm in the bubbling liquid. Spoon extra burst tomatoes and briny sauce over each piece to keep the delicate flakes moist.
Storing and Reheating
- Store the cooled cod and sauce in an airtight container in the refrigerator for up to two days.
- Reheat gently on the stovetop over medium-low heat with a splash of water until just warmed through. Microwaving delicate white fish will make it tough and rubbery.
Common One-Pan Cod Questions
Can I use frozen cod?
Yes, but you must thaw it completely in the refrigerator overnight and pat it exceptionally dry with paper towels before searing to prevent excess water from watering down the tomato sauce.
What can I use instead of white wine?
Chicken or vegetable broth mixed with an extra squeeze of fresh lemon juice makes a reliable substitute that still lifts the savory browned bits from the skillet.
Check the thickest fillet. Watch for a clean break. You will know the dish is done when the cod turns entirely opaque white and gives way with gentle pressure. Save this one-pan method for your next hurried weeknight when you want rich flavor without the cleanup.

One-Pan Mediterranean Cod with Burst Tomato Basil Sauce
This vibrant, single-skillet dinner takes everything to love about pan-seared white fish and streamlines the process. By searing the cod first and building a garlicky, wine-infused tomato sauce in the exact same pan, you capture all the savory browned bits for a richer flavor while cutting down on dishwashing. A handful of briny capers finishes the dish with a bright, savory punch.

Ingredients
For the Cod
- 1 ½ pounds (680g) fresh cod fillets, cut into 4 equal portions
- 1 teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
- 3 tablespoons (45ml) extra-virgin olive oil, divided
For the Burst Tomato Sauce
- 1 pint (10 oz / 283g) cherry or grape tomatoes
- 4 large garlic cloves, thinly sliced
- ¼ teaspoon crushed red pepper flakes
- ½ cup (120ml) dry white wine (such as Pinot Grigio or Sauvignon Blanc)
- 2 tablespoons (17g) capers, drained
- ½ teaspoon granulated sugar
- 1 teaspoon fresh lemon zest
- 1 tablespoon (15ml) fresh lemon juice
- ½ cup (12g) loosely packed fresh basil leaves, roughly torn
Instructions
- Prep and sear the fish: Pat the cod fillets completely dry with paper towels (this ensures a golden crust). Season both sides evenly with the kosher salt and black pepper. Heat 1 tablespoon of the olive oil in a large skillet over medium-high heat. Add the cod and sear until golden brown on the bottom, about 3 to 4 minutes. Carefully flip the fillets, cook for 1 minute more, then transfer them to a plate. (The fish will not be fully cooked yet.)
- Blister the tomatoes: Reduce the skillet heat to medium. Add the remaining 2 tablespoons of olive oil. Add the cherry tomatoes and cook, stirring occasionally, until they soften, blister, and begin to burst, about 5 to 7 minutes.
- Aromatize the sauce: Stir in the sliced garlic and crushed red pepper flakes. Cook until the garlic is fragrant and softened but not browned, about 1 minute.
- Deglaze and simmer: Pour in the white wine, scraping the bottom of the skillet with a wooden spoon to release any browned bits. Let the wine bubble and reduce by half, about 2 to 3 minutes. Stir in the capers, sugar, lemon zest, and lemon juice.
- Finish the dish: Nestle the partially cooked cod fillets back into the skillet along with any resting juices from the plate. Spoon some of the tomato sauce over the fish. Let everything simmer gently for 2 to 3 minutes, or until the cod flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
- Garnish and serve: Remove the skillet from the heat, scatter the fresh torn basil over the top, and serve immediately.
Notes
- Why it works: Searing the fish first leaves a layer of savory fond in the pan. When you deglaze with the white wine later, that concentrated flavor lifts right off the bottom and builds a deeply savory backbone for the tomato sauce.
- Moisture control: The single most common pitfall when pan-searing white fish is excess surface moisture, which causes the fillets to steam rather than brown. Don’t skip patting the fish dry with paper towels immediately before seasoning.
