Instructions

  1. Step 1: Pat dry 4 cod fillets (6 oz each) and season both sides with 1 tsp sea salt, 1/2 tsp black pepper, and 1 tsp smoked paprika.
  2. Step 2: In a blender, combine 1 cup roasted red peppers, 1/3 cup toasted almonds, 2 peeled garlic cloves, 1 tbsp sherry vinegar, and 1 tbsp tomato paste; blend until smooth while slowly drizzling in 1/4 cup extra virgin olive oil to create a thick, vibrant Romesco sauce. Set aside.
  3. Step 3: Heat 3 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering but not smoking.
  4. Step 4: Add the cod fillets skin-side down and sear without moving for 4-5 minutes until the edges are golden and crisp.
  5. Step 5: Carefully flip the fillets and cook for an additional 3 minutes until the fish flakes easily with a fork.
  6. Step 6: Plate the cod and spoon generous amounts of Romesco sauce over or alongside each fillet before serving immediately.

How do I store leftover Crisp Pan-Seared Spanish Cod with Romesco Sauce?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Crisp Pan-Seared Spanish Cod with Romesco Sauce?

How do I scale Crisp Pan-Seared Spanish Cod with Romesco Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
