Spanish Grilled Cod Ingredients
• Prepare to make a delicious dish that captivates your taste buds with these essential ingredients!
For the Cod
- Cod Steaks – The star of the show, providing a delicate flavor; feel free to substitute with haddock for a different twist!
- Olive Oil – Key for grilling, adding richness to both the cod and Romesco; extra virgin is recommended for enhanced flavor.
- Smoked Paprika – This spice brings a smoky depth to both the fish and the sauce; regular paprika can provide a milder kick.
- Sea Salt and Black Pepper – Essential for elevating the flavors; using kosher salt will give you better control over seasoning.
For the Romesco Sauce
- Red Bell Peppers – These sweet, colorful gems form the base of your sauce; jarred roasted peppers make for a convenient substitute.
- Almonds – They introduce a delightful nuttiness to the mix; pine nuts can be swapped for a fun flavor twist.
- Garlic Cloves – Fresh garlic adds a robust depth to the sauce; if you’re in a hurry, powdered garlic works too!
- Crusty Bread – Not just for texture; it thickens the Romesco beautifully; gluten-free bread can keep it inclusive.
- Sherry Vinegar – This ingredient lends the sauce acidity and brightness; if unavailable, red wine vinegar is a solid alternative.
- Fresh Parsley – A pop of freshness for garnish; it’s optional but definitely enhances the dish’s presentation.
- Lemon Wedges – A squeeze of lemon adds brightness to each bite; while optional, they are highly recommended for flavor enhancement.
Step‑by‑Step Instructions for Spanish Grilled Cod
Step 1: Prepare the Romesco Sauce
Begin by roasting the red bell peppers until charred, which takes about 15-20 minutes at 450°F. In a blender, combine the roasted peppers, toasted almonds, garlic cloves, crusty bread, sherry vinegar, and smoked paprika. Blend until everything is well mixed, then drizzle in olive oil slowly until it reaches a thick, creamy consistency. Season with salt and pepper to taste, then set the sauce aside.
Step 2: Preheat the Grill
While the Romesco sauce is coming together, preheat your grill to high heat, around 400-450°F. This ensures that your Spanish Grilled Cod cooks evenly and gets those beautiful grill marks. Meanwhile, brush both sides of the cod steaks generously with olive oil to enhance their flavor and prevent sticking.
Step 3: Season the Cod
Season the cod steaks liberally with smoked paprika, sea salt, and black pepper. Aim for a nice even coating to highlight the dish’s flavors. Let the seasoned cod sit for about 5-10 minutes to absorb the seasoning, allowing the grill to reach its optimal cooking temperature in the meantime.
Step 4: Grill the Cod
Carefully place the seasoned cod steaks on the hot grill. Grill for about 3-4 minutes on each side. The fish is done when it turns opaque and flakes easily with a fork, signaling perfect doneness. Keep an eye on it, as overcooking can dry out the cod, but don’t flip it too soon to maintain delicious grill marks.
Step 5: Serve the Dish
Once the cod is perfectly grilled, transfer the steaks to a serving platter. Generously spoon the creamy Almond Romesco Sauce over the top, allowing the vibrant colors to shine through. For an added touch, garnish with fresh parsley and serve alongside lemon wedges for an extra burst of brightness in each bite.

Spanish Grilled Cod with Almond Romesco Sauce Recipe FAQs
How do I choose the best cod steaks?
Look for cod that is firm to the touch with a translucent appearance. Fresh cod should have a mild scent of the ocean and no dark spots; if the fish has a fishy smell or discoloration, it’s best to avoid it. If you’re in doubt, ask your fishmonger for their freshest catch!
How should I store leftover Spanish Grilled Cod?
Store any leftover cod in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, gently reheat it in the oven at a low temperature (around 275°F) until warmed through, being careful not to dry it out.
Can I freeze the Romesco sauce?
Absolutely! You can freeze the almond Romesco sauce for up to 3 months. To do this, spoon it into an airtight container or freezer bag, and label it with today’s date. When you’re ready to use it, simply transfer it to the refrigerator to thaw overnight before serving.
What if my Romesco sauce is too thick?
If your Romesco sauce ends up thicker than desired, no worries! You can adjust the consistency by adding a bit of water or more olive oil, blending again until you achieve your preferred creamy texture. Keeping it slightly chunky adds character, so blend it gently towards the end!
Are there any dietary considerations I should be aware of for this recipe?
It’s good to note that while this delicious Spanish Grilled Cod is packed with healthy nutrients, those with nut allergies should avoid the almonds in the Romesco sauce. Instead, consider substituting with sunflower seeds or omit them entirely. Always double-check for ingredients that cater to your guests’ dietary restrictions.
Can I use other fish instead of cod?
Very much so! This recipe is versatile; use any firm white fish like haddock or even salmon for richer flavor. For a delightful vegetarian option, you can grill vegetables such as zucchini or eggplant and serve them with the Romesco sauce for a fantastic meal!
