Pan-Seared Flounder with Burst Cherry Tomato Sauce

Ingredients

2 tablespoons all-purpose flour 1 teaspoon table salt, divided¼ teaspoon pepper 6 (4- to 6-ounce) skinless flounder fillets, ¼ to ½ inch thick4 teaspoons vegetable oil, divided3 garlic cloves, minced10 ounces cherry tomatoes ⅓ cup dry white wine ⅓ cup water ¼ teaspoon red pepper flakes 1 tablespoon chopped fresh oregano

Before You Begin

Sole or tilapia may be substituted for the flounder. If using tilapia, let the fillets stand for 30 to 60 seconds at the end of step 3. To use frozen fish, thaw and then let it sit between triple layers of paper towels for 10 minutes, replacing towels as needed and dabbing with towels until almost no moisture appears.

Instructions

  1. Whisk 2 tablespoons all-purpose flour, ½ teaspoon table salt, and ¼ teaspoon pepper together in small bowl. Reserve 1 teaspoon flour mixture, then spread remaining mixture in even layer on large plate. 
  2. Dry 6 skinless flounder fillets thoroughly with paper towels. Place 3 fillets, skinned side down, into flour mixture on plate to coat 1 side. Shake off excess and transfer to rimmed baking sheet, floured side up. 
  3. Heat 1½ teaspoons vegetable oil in 12-inch skillet over medium-high heat until just smoking. Carefully place fillets, floured side down, in pan and cook until bottom is golden brown, about 2 minutes. Remove skillet from heat. Using 2 thin spatulas, gently flip fillets and let stand until second side is opaque, 15 to 30 seconds. Transfer fillets, browned side up, to platter. Wipe out skillet with paper towels and repeat steps 2 and 3 with remaining fillets and 1½ teaspoons oil.
  4. Wipe out skillet with paper towels. Add remaining 1 teaspoon oil and 3 minced garlic cloves and cook over medium heat until fragrant, about 30 seconds. Stir in reserved 1 teaspoon flour mixture and cook for 15 seconds. Add 10 ounces cherry tomatoes, ⅓ cup white wine, ⅓ cup water, ¼ teaspoon pepper flakes, and remaining ½ teaspoon salt and bring to simmer. Cover and cook, stirring occasionally, until tomatoes have burst, about 5 minutes. Uncover and continue to cook, breaking up tomatoes with back of wooden spoon, until sauce has thickened slightly, about 2 minutes. 
  5. Off heat, stir in 1 tablespoon chopped oregano. Spoon sauce over fish and serve.

Why This Recipe Works

Quick-cooking, versatile flatfish such as flounder and sole are ultraconvenient for a weeknight dinner, but they can also be tricky, as they’re prone to overcooking and turning dry and their delicate flesh can easily tear. To guard against overcooking, we thoroughly dried the fish and dredged it with flour on one side, as excess moisture can impede browning and slow down cooking. Using a well-oiled stainless-steel skillet rather than nonstick allowed us to cook the fish at a higher temperature, quickly altering the proteins in the fish to keep them from bonding to the pan. We cooked the fish on one side only and used the residual heat in the pan to finish the other side to ensure the flaky flesh stayed moist. The delicate sweetness of the fish paired perfectly with a vibrant, fruity sauce made from burst cherry tomatoes, fresh oregano, and a kick of red pepper flakes.
