Ingredients You’ll Need
The beauty of the Perfectly Grilled Cod with Homemade Romesco Sauce Recipe lies in its straightforward ingredients that come together harmoniously to elevate the dish. Each component plays a key role—whether it’s the tender cod, the roasted peppers adding smoky sweetness, or the nuts giving the sauce its signature texture and depth.
- 4 cod fillets (6 oz each): Fresh or thawed, firm white fish is best for a juicy, flaky bite.
- 1 tbsp olive oil: For brushing the fish, adding a subtle fruity richness while grilling.
- Salt and freshly ground black pepper, to taste: Essential seasonings to enhance the natural flavors.
- 1 tsp lemon zest (optional): A bright citrus note that lifts the dish with freshness.
- Fresh parsley, chopped (for garnish): Adds a pop of green color and herbaceous aroma.
- 1 large red bell pepper, roasted and peeled: Brings the smoky, sweet base for the romesco sauce—jarred roasted peppers work perfectly too.
- 2 medium tomatoes, roasted and peeled: Provide a bright, tangy foundation for the sauce; fire-roasted canned tomatoes are a convenient alternative.
- ¼ cup almonds (or nuts like hazelnuts or walnuts): Adds a rich, nutty texture that makes the romesco sauce so special.
- 2 cloves garlic, minced: Infuses the sauce with warm, aromatic depth.
- 2 tbsp red wine vinegar: Balances the sweetness of the vegetables with a sharp acidity.
- 1 tbsp smoked paprika (or regular paprika): Delivers the signature smoky warmth to the sauce.
- 1 tbsp olive oil: Binds the sauce components together with a silky finish.
- Salt and freshly ground black pepper, to taste: Ensures the romesco sauce is perfectly seasoned.
- 1-2 tbsp water (to adjust consistency): Helps reach the ideal sauce texture without watering down flavors.
How to Make Perfectly Grilled Cod with Homemade Romesco Sauce Recipe
Step 1: Prepare the Romesco Sauce
Start by assembling the heart of this dish—the romesco sauce. Roast the red bell pepper and tomatoes until their skins blister and char slightly, releasing their natural sweetness and smokiness. Once cooled, peel them carefully and blend with toasted almonds, minced garlic, red wine vinegar, paprika, olive oil, and a pinch of salt and pepper. Add water little by little to create a velvety smooth consistency that clings to the fish beautifully. This homemade sauce is rich, smoky, nutty, and perfectly balanced—a true star of the recipe.
Step 2: Season and Grill the Cod Fillets
Next, brush each cod fillet lightly with olive oil and season generously with salt, freshly ground black pepper, and if you love a citrus twist, a touch of lemon zest. Heat your grill or grill pan to medium-high and cook the cod for about 4-5 minutes per side, depending on thickness. The goal is a golden exterior with a moist, tender interior that flakes easily when tested with a fork. Grilling the fish imparts a subtle smoky flavor that pairs perfectly with the robust romesco.
Step 3: Plate and Serve
Once grilled, gently transfer the cod fillets to serving plates. Spoon a generous amount of the luscious homemade romesco sauce over each piece, letting the bold red color and rich aroma entice your senses. Garnish with a sprinkle of fresh chopped parsley to add a fresh herbal note and visual contrast. This is when your dish truly comes to life—vibrant, inviting, and ready to be enjoyed.
How to Serve Perfectly Grilled Cod with Homemade Romesco Sauce Recipe

Garnishes
Fresh parsley not only adds a cheerful pop of green but also a subtle freshness that balances the smoky sauce beautifully. For an added citrus punch, consider thin lemon wedges on the side so everyone can brighten their fish to taste. A drizzle of extra virgin olive oil right before serving can also elevate the flavors even more.
Side Dishes
The romesco sauce’s bold flavors lend themselves wonderfully to simple, crisp sides. Think grilled asparagus, sautéed green beans, or a light salad with arugula and citrus segments. You can also serve this dish alongside creamy mashed potatoes or a fluffy rice pilaf to soak up every flavorful drop of sauce with each bite.
Creative Ways to Present
For a stunning presentation, consider layering the cod on a bed of roasted vegetables before spooning the romesco sauce on top. Alternatively, serve the sauce on the side in a small dipping bowl for a communal dining experience where everyone adds as much as they like. Garnishing with crushed toasted almonds enhances the nutty notes and adds crunch for textural interest.
Make Ahead and Storage
Storing Leftovers
Store any leftover grilled cod and romesco sauce separately in airtight containers in the refrigerator. The fish will remain good for up to 2 days, while the sauce can last for about 3-4 days, allowing you to enjoy the flavors freshly without compromising texture.
Freezing
While grilled cod does not freeze exceptionally well due to its delicate nature, the romesco sauce freezes beautifully. Pour the sauce into a freezer-safe container and it will keep for up to 3 months. Thaw it overnight in the refrigerator before reheating gently on the stove.
Reheating
Reheat the cod gently in a low oven or covered in a pan on the stove to avoid drying it out, as high heat can toughen the fish. Warm the romesco sauce slowly on the stove, stirring constantly until heated through. Reapply sauce generously to bring back the dish’s vibrant flavors.
FAQs
Can I use frozen cod for this recipe?
Absolutely! Just be sure to thaw the cod completely and pat it dry before seasoning and grilling to prevent excess moisture and ensure it cooks evenly.
What if I don’t have a grill?
No problem at all. You can cook the cod in a grill pan on the stovetop, broil it in the oven, or even pan-sear it. The key is achieving a nice sear without overcooking.
Can I substitute the almonds in the romesco sauce?
Yes, hazelnuts or walnuts work wonderfully and each brings a slightly different nuttiness, depending on what you have on hand or your flavor preference.
How spicy is the romesco sauce? Can I make it milder?
The recipe as written is smoky and slightly tangy but not spicy. If you’d like to add heat, a pinch of cayenne or some red pepper flakes will do the trick. For milder versions, simply omit extra spices beyond paprika.
Is this recipe suitable for meal prep?
Definitely! The romesco sauce can be made several days ahead, and the grilled cod can be cooked just before eating or gently reheated. This makes it a convenient, flavorful option for quick meals all week long.
Final Thoughts
I can’t recommend the Perfectly Grilled Cod with Homemade Romesco Sauce Recipe enough for anyone looking to impress with minimal effort but maximum flavor. It’s elegant, comforting, and packed with the kind of bold, balanced flavors that turn any meal into a celebration. Give it a try — your taste buds will thank you!

Ingredients
For the Cod:
- 4 cod fillets (6 oz each)
- 1 tbsp olive oil
- Salt and freshly ground black pepper, to taste
- 1 tsp lemon zest (optional)
- Fresh parsley, chopped (for garnish)
For the Romesco Sauce:
- 1 large red bell pepper, roasted and peeled (or use jarred roasted red peppers)
- 2 medium tomatoes, roasted and peeled (or use canned fire-roasted tomatoes)
- ¼ cup almonds (or other nuts like hazelnuts or walnuts)
- 2 cloves garlic, minced
- 2 tbsp red wine vinegar
- 1 tbsp smoked paprika (or regular paprika)
- 1 tbsp olive oil
- Salt and freshly ground black pepper, to taste
- 1–2 tbsp water (to adjust consistency)
Instructions
- Prepare the Romesco Sauce: Begin by pureeing the roasted red bell pepper, roasted tomatoes, almonds, minced garlic, red wine vinegar, smoked paprika, and olive oil in a food processor until smooth. Add salt and freshly ground black pepper to taste. Adjust the consistency by adding 1-2 tablespoons of water if needed until you reach a smooth, pourable sauce.
- Season the Cod: Pat dry the cod fillets with paper towels. Brush both sides of each fillet with olive oil and season generously with salt, freshly ground black pepper, and lemon zest if using. The lemon zest adds a fresh brightness to the fish.
- Grill the Cod: Preheat the grill to medium-high heat. Place the seasoned cod fillets on the grill and cook for about 4-5 minutes on each side, or until the fish is opaque and flakes easily with a fork. Avoid overcooking to maintain the fish’s moistness.
- Serve: Plate the grilled cod fillets and generously spoon the Romesco sauce over or beside them. Garnish with freshly chopped parsley for a burst of color and freshness. Serve immediately for the best flavor and texture.
Notes
- You can roast the bell pepper and tomatoes yourself by charring them over a flame or under a broiler and then peeling off the skins, or use high-quality jarred roasted peppers and canned fire-roasted tomatoes for convenience.
- If you don’t have smoked paprika, regular paprika works, but the smoky flavor is distinctive for this sauce.
- Almonds can be substituted with hazelnuts or walnuts depending on preference and availability.
- Use a food processor or blender to get a smooth Romesco sauce texture, adjusting water as needed.
- To check doneness of the cod, the flesh should flake easily when tested with a fork but still remain moist inside.
