This delicious, healthy recipe highlights the art of gently cooking cod in a vibrant tomato and wine broth alongside salty olives and tangy capers, all finished with a flourish of parsley.

Whether you’re looking for an easy weeknight dinner, a wholesome main dish for entertaining, or a way to incorporate more seafood into your diet, this recipe delivers big on both flavor and nutrition. Let’s explore everything that makes this dish a perennial favorite—from its ingredients and preparation to its nutritional profile and Mediterranean inspiration.

The Inspiration: Mediterranean Cooking Simplified

The Mediterranean diet is renowned for its emphasis on fresh produce, healthy fats, lean protein, and bold flavor combinations. Dishes like this tomato-poached cod draw on pantry staples typical of Southern French and Italian cuisine—think olive oil, garlic, ripe tomatoes, briny olives, and zesty capers. The use of dry rosé wine not only adds depth to the poaching liquid but brings a subtle acidity that perfectly balances the natural sweetness of the tomatoes and the mildness of cod.

Similar recipes, like Cod Provençal, originate from Provence and highlight key ingredients such as extra-virgin olive oil, sun-ripened tomatoes, local olives, fresh herbs, and capers, all coming together in one pan.

Why Poaching Cod?

  • Moisture Preservation: Poaching gently cooks cod in liquid, keeping the flesh tender and moist throughout the process—never tough or dry.
  • Flavor Infusion: The cod fillets absorb savory and tangy notes from the tomatoes, wine, olives, and capers.
  • Simplicity: One-skillet preparation means minimal cleanup and maximum convenience.

Step-by-Step Directions

  1. Sauté aromatics: Heat olive oil in a large skillet on medium. Add sliced garlic, capers, and lemon zest, stirring occasionally. Cook until garlic is lightly golden brown (about 2 minutes).
  2. Add the wine: Pour in the dry rosé and simmer for 2 minutes to allow the alcohol to evaporate and flavors to concentrate.
  3. Build the sauce: Stir in quartered tomatoes, halved olives, and a pinch (¼ tsp each) of salt and pepper. Simmer gently so the tomatoes start to break down, becoming saucy and fragrant.
  4. Poach the cod: Place cod fillets into the skillet, nestling them into the tomato mixture. Allow the fish to simmer, covering the skillet for the last 3 minutes. Cook until the cod is opaque and flakes easily with a fork (6-8 minutes total).
  5. Finish and serve: Sprinkle with chopped fresh parsley before serving for a burst of color and freshness.

Tips for Perfect Poaching

  • Use fresh, high-quality cod fillets for best texture and flavor.
  • Don’t overcook the fish—cod is best when moist and just opaque.
  • Dry rosé or dry white wine works best. Avoid sweet wines.
  • Quartered Campari tomatoes hold their shape and release sweetness; substitute with ripe Roma or vine tomatoes if needed.
  • Kalamata olives impart deep, fruity notes; green olives offer a sharper contrast.
