How to Make Grilled Cod with Romesco Sauce

Step 1: Make the Romesco Sauce
In a food processor, blend roasted red peppers, toasted almonds, garlic, torn bread, sherry vinegar, and smoked paprika until fairly smooth.

With the motor running, slowly drizzle in the olive oil until thick and creamy.

Season with salt and pepper to taste.

Step 2: Prep the Cod
Preheat your grill to high.

Brush cod steaks with olive oil, then sprinkle with smoked paprika, salt, and pepper.

Step 3: Grill the Cod
Place the steaks directly on the grill.

Cook for 3–4 minutes per side, or until the fish flakes easily with a fork and has nice grill marks.

Step 4: Plate and Garnish
Spoon generous amounts of romesco sauce onto plates or a serving dish.

Top with grilled cod. Garnish with fresh parsley and lemon wedges.
