Instructions

  1. Step 1: Season 4 cod fillets (150 g each) with 1 tsp salt and 1/2 tsp black pepper on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat. Add the cod fillets skin-side down and cook for 4-5 minutes without moving until golden and crisp. Flip and cook for another 3-4 minutes until opaque and cooked through. Remove and keep warm.
  3. Step 3: Meanwhile, roughly chop 2 roasted red peppers and place them in a blender with 1/4 cup toasted almonds, 2 peeled garlic cloves, 1 slice of day-old bread torn into pieces, 2 tbsp sherry vinegar, 1/2 tsp smoked paprika, 3 tbsp water, and 1/4 tsp red chili flakes if using. Blend until smooth and creamy.
  4. Step 4: Heat 2 tbsp olive oil in a small saucepan over low heat and stir in the romesco sauce to warm gently for 2 minutes.
  5. Step 5: Serve the pan-fried cod fillets topped with the warm romesco sauce and a drizzle of olive oil.

Frequently asked questions

How long does Pan-Fried Cod with Romesco Sauce take to make?

Total time is about 30 minutes (15 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Fried Cod with Romesco Sauce?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Pan-Fried 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 Pan-Fried 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.

What goes well with Pan-Fried Cod with Romesco Sauce?

Spanish seafood like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
