Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat dry 4 cod fillets (6 oz each) and brush both sides with 1 tbsp olive oil. Sprinkle 1 tsp smoked paprika, sea salt, and black pepper evenly on both sides.
  2. Step 2: Place the cod fillets on a baking sheet lined with parchment paper and bake for 12-15 minutes until the fish is opaque and flakes easily with a fork.
  3. Step 3: Meanwhile, in a food processor, combine 1 cup roasted red peppers (drained), 1/4 cup toasted almonds, 3 minced garlic cloves, 2 tbsp tomato paste, 1 tbsp sherry vinegar, and 2 tbsp olive oil. Blend until smooth, scraping down the sides to create a thick Romesco sauce.
  4. Step 4: Taste the sauce and season with salt and pepper as needed. Spoon the Romesco sauce over the baked cod fillets and garnish with 2 tbsp chopped fresh parsley before serving.

How do I store leftover Baked Spanish-Style 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 Baked Spanish-Style Cod with Romesco Sauce?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Baked Spanish-Style 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.
