How to Make Spanish Grilled Cod with Almond Romesco Sauce Recipe
Step 1: Make the Romesco Sauce
Begin by assembling the sauce, which is the heart of this recipe. Combine the roasted red bell pepper, toasted almonds, chopped tomato, garlic clove, red wine vinegar, smoked paprika, and optional cayenne pepper in a food processor or blender. Pulse the mixture until everything is finely chopped but still has some texture. Slowly stream in the olive oil while blending to create a smooth but slightly textured sauce. Season thoughtfully with salt and pepper, adjusting to your taste. You can make this ahead of time and keep it chilled, which only enhances the flavors.
Step 2: Prepare the Cod Fillets
Pat your cod fillets dry with paper towels—this is essential to achieve a lovely crust when grilling. Brush each fillet with olive oil to prevent sticking and help the seasoning cling. In a small bowl, mix smoked paprika, garlic powder, salt, and black pepper, then sprinkle evenly over both sides of the cod. Preheat your grill or grill pan to medium-high heat, ensuring it’s hot before placing the fish down.
Step 3: Grill the Cod
Grill the seasoned fillets for about 3 to 4 minutes on each side. You’ll know the fish is ready when it turns opaque and flakes effortlessly with a fork. Flip the fillets carefully to keep them intact—gentle hands are your best friend here. Once grilled, your cod is ready to be paired with the luxurious almond romesco sauce.
Step 4: Plate and Serve
Serve each cod fillet with a generous spoonful of your homemade almond romesco sauce. Don’t forget a few lemon wedges on the side to add that final splash of freshness. This dish immediately brings a restaurant-quality meal to your home.

Garnishes
A sprinkle of fresh parsley or chopped chives adds a pop of green and an herby brightness that complements the smoky and nutty sauce beautifully. You can also toss on a handful of toasted almond slivers for an extra crunch and visual appeal.
Side Dishes
The rich flavors of the Spanish Grilled Cod with Almond Romesco Sauce Recipe pair wonderfully with roasted potatoes, grilled seasonal vegetables, or even a fresh green salad tossed with a lemony vinaigrette. These sides add dimension and help make this meal satisfyingly complete.
Creative Ways to Present
For a chic and modern presentation, serve the fillets on a bed of lightly sautéed spinach or quinoa with the romesco artistically drizzled over the top. Alternatively, present the cod on rustic wooden boards alongside small bowls of additional sauce and lemon wedges for a tapas-style experience.
Make Ahead and Storage
Storing Leftovers
Any leftover Spanish Grilled Cod with Almond Romesco Sauce Recipe can be stored in an airtight container in the refrigerator for up to 2 days. The sauce might thicken a bit when chilled, but simply stir it before serving again.
Freezing
While the cod is best enjoyed fresh, you can freeze the almond romesco sauce separately in a sealed container for up to 1 month. Thaw in the refrigerator before using and give it a good stir.
Reheating
To reheat the grilled cod, gently warm it in a low oven (around 275°F/135°C) to avoid drying out the delicate fish. Reheat the sauce separately in a small pan or microwave for a few seconds until warm.
FAQs
Can I use other types of fish for this recipe?
Absolutely! While cod is ideal for its flaky texture and mild flavor, you can experiment with halibut, haddock, or even sea bass. Just adjust the grilling time depending on the thickness of the fillets.
Is the almond romesco sauce spicy?
It can be, depending on whether you include the optional cayenne pepper. The base sauce is more smoky, nutty, and tangy, but the cayenne offers a subtle heat if you like things with a little kick.
Can I prepare the sauce without a food processor?
While a food processor is perfect for achieving the right texture, you can finely chop all the ingredients by hand and then vigorously whisk in the olive oil. The sauce will be chunkier but still delicious.
What wine pairs well with Spanish Grilled Cod with Almond Romesco Sauce Recipe?
A crisp, dry white wine like Albariño or a light Verdejo complements the smoky paprika and almond flavors beautifully, offering a refreshing balance to the richness of this dish.
Is this recipe gluten-free and dairy-free?
Yes, it naturally is. The ingredients used are gluten-free and dairy-free, making this Spanish Grilled Cod with Almond Romesco Sauce Recipe perfect for those with dietary restrictions.
