Ingredients You’ll Need

From the silky cod fillets to the roasted red pepper and toasted almonds in the sauce, every element is thoughtfully chosen for its contribution to this vibrant dish.
- Cod fillets (4 x 6 oz): Fresh, firm cod is perfect for grilling and holds up beautifully under the romesco sauce.
- Olive oil (2 tablespoons): Adds richness and helps create a crisp exterior on the cod while keeping it moist.
- Smoked paprika (1 teaspoon): Brings a subtle smoky depth that complements the grilled fish and romesco sauce.
- Sea salt (1/2 teaspoon): Enhances all the natural flavors without overpowering.
- Black pepper (1/4 teaspoon): Provides a gentle heat and balances the seasoning.
- Lemon wedges: The bright acidity adds freshness and a burst of citrusy brightness when squeezed over the fish.
- Roasted red bell pepper (1 large): The star ingredient in the almond romesco sauce, lending a sweet, smoky charm.
- Blanched almonds (1/3 cup, toasted): Toasting intensifies their nutty flavor, giving the sauce a luscious texture and richness.
- Garlic clove (1 small): Adds subtle pungency and warmth to the sauce.
- Tomato paste (1 tablespoon): Builds a concentrated depth of tomato flavor and balances the sauce’s sweetness.
- Red wine vinegar (1 tablespoon): Infuses the sauce with tang and brightness that cuts through the richness.
- Cayenne pepper (1/4 teaspoon, optional): Gives a gentle heat kick if you want to spice things up a bit.

How to Make Spanish Grilled Cod with Almond Romesco Sauce Recipe
Step 1: Prepare the Cod
Begin by preheating your grill or grill pan to medium-high heat. Pat the cod fillets dry with paper towels — this step is crucial for achieving that beautiful sear. Rub each fillet evenly with olive oil, smoked paprika, sea salt, and black pepper. Let the flavors settle for a few minutes while you move on to the sauce.
Step 2: Craft the Almond Romesco Sauce
This sauce is where all the magic comes together. In a food processor, combine the roasted red bell pepper, toasted almonds, garlic, tomato paste, red wine vinegar, smoked paprika, cayenne (if using), and salt. Pulse until the mixture is finely blended but still has some texture to keep it interesting. As the processor runs, slowly drizzle in olive oil until the sauce becomes smooth and emulsified. Taste and adjust seasoning as needed to get that perfect balance of smokiness, tang, and richness.
Step 3: Grill the Cod
Place the prepared cod fillets on the hot grill and cook for 3 to 4 minutes per side. You’re looking for the fish to turn opaque and flake easily with a fork — a sign it’s perfectly cooked and tender. Avoid overcooking to maintain that melt-in-your-mouth texture.
Step 4: Serve with Love
Once grilled, transfer the cod fillets to plates and generously spoon the almond romesco sauce over each one. Finish with a squeeze of fresh lemon juice to brighten every bite.
How to Serve Spanish Grilled Cod with Almond Romesco Sauce Recipe

Garnishes
Extra touches bring this dish to life. A sprinkle of fresh chopped parsley or a few toasted almonds on top adds a pop of color and crunch. Lemon wedges on the side give each person the option to add their preferred amount of citrus zing.
Side Dishes
This recipe pairs beautifully with simple, fresh complements. Think roasted potatoes dusted with herbs, fluffy rice, or a light arugula salad dressed with olive oil and lemon.

Creative Ways to Present
For a stunning presentation, serve the cod on a rustic wooden board with small bowls of extra almond romesco and lemon wedges for a communal feel. Or plate each serving atop a bed of sautéed greens or alongside grilled veggies for an elegant, colorful meal that delights the eyes as much as the palate.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers of this Spanish Grilled Cod with Almond Romesco Sauce Recipe, they keep well in an airtight container in the fridge for up to two days. The flavors develop even more, making for a delicious next-day meal.
Freezing
