Tomato-Poached Cod with Olives and Capers

When it comes to healthy, delicious fish dinners that can be prepared effortlessly on a busy weeknight, few dishes capture the zesty, sun-drenched essence of the Mediterranean like tomato-poached cod with olives and capers. This simple yet vibrant recipe transforms mild cod fillets into something truly special by simmering them in a bright tomato sauce alongside briny olives, tangy capers, lemon, and a touch of wine. The result is a meal that’s both light and deeply satisfying, packed with flavor and nutrients.

The Beauty of Poached Fish

Poaching is one of the most forgiving methods for preparing delicate fish like cod. Instead of risking dry, overcooked fillets, you gently cook them in a flavorful liquid—usually a combination of fresh ingredients and aromatics. This process keeps the fish moist, tender, and perfectly cooked throughout. Tomato-poaching, in particular, infuses the cod with layers of Mediterranean flavors and creates a built-in sauce for serving.

Why This Dish Stands Out

  • Quick and Easy: Ready in less than 30 minutes, making it ideal for weeknights.
  • One-Pan Recipe: Minimal cleanup required.
  • Healthy and Nutritious: Cod is lean and rich in protein; tomatoes add antioxidants.
  • Mediterranean Flavors: The combo of olives, capers, garlic, and lemon brightens every bite.
  • Adaptable: Easily swap in other white fish or add your favorite vegetables and herbs.

Understanding Provençal Cooking

Provençal cuisine hails from the region of Provence in Southern France and celebrates ingredients that thrive under the Mediterranean sun: olive oil, ripe tomatoes, garlic, briny olives, and fragrant herbs like thyme and parsley. This style of cooking emphasizes freshness and balance, letting the natural flavors of simple ingredients shine. Variations of tomato-poached cod exist across the Mediterranean, but the essence remains the same—celebrate seasonal produce and high-quality seafood in easy, nourishing dishes.

Ingredients for Tomato-Poached Cod with Olives and Capers

  • Olive Oil: Use extra-virgin for the best flavor.
  • Garlic: Thinly sliced to slowly perfume the cooking oil.
  • Capers: Rinsed to tame their brininess; provide punchy, salty contrast.
  • Lemon Zest: Adds fresh, citrusy aroma.
  • Dry Rosé Wine: Preferably from Southern France or Italy, adds acidity and depth.
  • Campari Tomatoes: Or use ripe, juicy tomatoes of your choice, quartered.
  • Kalamata Olives: Pitted and halved, for a briny, savory note.
  • Kosher Salt and Black Pepper: For basic seasoning.
  • Cod Fillets: Skinless, about 6 ounces each; can substitute with other mild white fish.
  • Chopped Parsley: For garnish and fresh, herbal finish.

Ingredient Table

IngredientQuantity
Olive oil2 Tbsp
Garlic, thinly sliced2 cloves
Capers, rinsed1 Tbsp
Lemon zest, thinly sliced1 strip
Dry rosé wine3/4 cup
Campari tomatoes, quartered1/2 lb
Kalamata olives, pitted and halved1/4 cup
Kosher salt and pepperTo taste
Cod fillets, skinless4 (6 oz each)
Chopped parsleyFor serving

Step-by-Step Directions

  1. Infuse the Oil: In a large skillet, heat the olive oil with garlic, capers, and lemon zest over medium heat. Stir occasionally, letting the garlic turn lightly golden, about 2 minutes.
  2. Deglaze and Build the Sauce: Pour in the dry rosé wine and let it simmer for 2 minutes to burn off the alcohol and concentrate the flavors.
  3. Add Vegetables: Stir in the tomatoes, olives, and 1/4 teaspoon of both salt and pepper. Allow the tomatoes to begin breaking down and releasing their juices, making a rich base for poaching.
  4. Poach the Fish: Nestle the cod fillets into the bubbling tomato mixture. Allow them to simmer gently. Cover the skillet during the last 3 minutes of cooking to ensure the fish remains moist. The cod is done in 6 to 8 minutes when it’s opaque and flakes easily with a fork.
  5. Finish and Serve: Sprinkle chopped parsley over the cooked fish and sauce for a burst of fresh flavor. Serve immediately, spooning the pan sauce generously over each fillet.

Ways to Customize Your Tomato-Poached Cod

This Mediterranean staple welcomes variation. Try some of these creative spins:

  • Use Different Fish: Substitute halibut, haddock, sea bass, or another firm, flaky white fish.
  • Add Vegetables: Toss in bell peppers, zucchini, or artichoke hearts to make the dish heartier.
  • Boost the Herbs: Fresh thyme, basil, oregano, or Herbes de Provence introduce new layers of aroma.
  • Add Spice: A pinch of red pepper flakes infuses gentle heat.
  • For More Depth: Sauté onions with the garlic or add a splash of clam juice or fish stock before poaching.
  • Lemon Juice: Squeeze fresh lemon juice on top for added brightness before serving.

Expert Tips for Perfect Poached Fish

  • Pat Fish Dry: This helps seasonings stick and ensures the cod cooks evenly.
  • Poach Gently: Simmer the fish; boiling can cause it to become tough or rubbery.
  • Don’t Overcook: Cod is done when it flakes easily; overcooked fillets will fall apart.
  • Season Well: A pinch of salt during every stage draws out and enhances flavors.
  • Serve Hot: This dish is best enjoyed fresh for optimum texture and flavor.

Serving Suggestions

  • Crusty Bread: Mop up the savory tomato-olive sauce with a slice of rustic bread, or keep it gluten-free by serving over polenta or a bed of steamed greens.
  • Pair with a Salad: A light arugula or fennel salad dressed with lemon vinaigrette offsets the gentle richness of the cod.
  • Wine Pairing: Complement the flavors with a chilled glass of dry rosé or a crisp Sauvignon Blanc.
