Ingredients You’ll Need
Gathering simple, fresh ingredients is the key to this dish’s success. Each one plays an essential role, either lending depth to the Romesco sauce or enhancing the delicate flavor and texture of the grilled cod.
- Cod fillets (4 pieces, 6 oz each): Choose fresh or thawed cod for a tender, flaky centerpiece.
- Olive oil (2 tbsp total): Used both in the Romesco sauce and to prevent sticking during grilling.
- Salt and freshly ground black pepper: Essential seasonings to bring out the natural flavors.
- Lemon zest (1 tsp, optional): Adds a subtle brightness that perfectly complements the fish.
- Fresh parsley, chopped: A fresh herb garnish that adds color and a mild herbal note.
- Roasted red bell pepper (1 large): For smoky sweetness; roasting fresh is ideal but jarred works great too.
- Tomatoes (2 medium, roasted): Adds a rich base with a slightly sweet acidity.
- Almonds (¼ cup): Provide the signature nutty creaminess in the Romesco sauce.
- Garlic (2 cloves, minced): Infuses the sauce with fragrant warmth.
- Red wine vinegar (2 tbsp): Balances the richness with a sharp tang.
- Smoked paprika (1 tbsp): Brings smoky depth and a hint of spice.
- Water (1-2 tbsp): To adjust Romesco sauce consistency to creamy perfection.
How to Make Grilled Cod with Homemade Romesco Sauce Recipe
Step 1: Prepare the Romesco Sauce
Start by roasting your red bell pepper and tomatoes if you’re using fresh produce — this enhances their sweetness and imparts a lovely smoky flavor. Roast them at 400°F until charred and tender. Once cooled, peel off the skins and remove seeds or stems. Then, blend these with almonds, garlic, red wine vinegar, smoked paprika, and olive oil until smooth. This sauce is the heart of the dish; its creamy texture and complex flavors will elevate your cod to the next level. Season with salt and pepper, and add a little water if you want a looser sauce.
Step 2: Grill the Cod
Preheat your grill to medium-high and lightly oil the grates to keep your cod from sticking. Pat the fillets dry, then season them simply with salt, pepper, and lemon zest if you like a bright citrus hint. Grill each fillet for about 3 to 4 minutes per side, allowing the fish to develop those enticing grill marks and cook through until it flakes easily with a fork. The firm yet delicate texture of grilled cod perfectly contrasts with the luscious Romesco sauce.
Step 3: Assemble and Serve
When your cod is grilled to perfection, plate the fillets and lavish them with generous spoonfuls of the homemade Romesco sauce. The vibrant red sauce cascading over the white fish creates a stunning visual and a complex burst of flavor with every bite. A sprinkle of fresh parsley adds a touch of freshness and color, inviting you to dive right in.
How to Serve Grilled Cod with Homemade Romesco Sauce Recipe

Garnishes
Chopped fresh parsley is the classic choice—it brings a lively green contrast and a subtle herbaceous note that balances the richness of the sauce. For an extra burst of freshness, you can add a few lemon wedges on the side so everyone can add a squeeze of juice if desired.
Side Dishes
This dish pairs beautifully with simple sides that won’t overpower it. Think light and vibrant like a crisp mixed green salad or steamed asparagus. Roasted baby potatoes or a fluffy couscous with fresh herbs can add some heartiness while keeping the meal balanced. The charm of the Grilled Cod with Homemade Romesco Sauce Recipe is its ability to be the star alongside so many accompaniments.
Creative Ways to Present
For an impressive presentation, serve the cod fillets atop a bed of the Romesco sauce rather than just spooning it over. Alternatively, serve the sauce on the side so guests can enjoy dipping with each bite. You could also plate with a swirl of sauce artistry using a spoon, garnished with finely chopped nuts and a drizzle of olive oil to add texture and shine.
Make Ahead and Storage
Storing Leftovers
Place any leftover grilled cod and Romesco sauce in airtight containers and refrigerate. The fish is best eaten within 1 to 2 days to maintain its fresh, flaky texture, while the Romesco sauce can usually last for up to 4 days and even develop deeper flavor.
Freezing
While you can freeze the Romesco sauce for up to 2 months in a sealed freezer-safe container, freezing grilled cod is not ideal as it tends to lose its delicate texture and can become mushy on reheating. It’s better to enjoy fresh or refrigerated leftovers.
Reheating
To reheat your cod gently, warm it in a low oven around 275°F until just heated through. Avoid microwaving to prevent drying out. The Romesco sauce can be warmed briefly on the stovetop or served at room temperature, which often tastes better and keeps its vibrant flavor.
FAQs
Can I use other types of fish instead of cod?
Absolutely! Firm white fish like halibut, haddock, or sea bass work wonderfully with this recipe. Just adjust grilling times based on thickness.
Is it possible to make the Romesco sauce without a food processor?
Yes, you can finely chop the ingredients by hand and mash them together with a mortar and pestle for a chunkier, rustic sauce.
How can I make this recipe gluten-free?
All ingredients in this Grilled Cod with Homemade Romesco Sauce Recipe are naturally gluten-free, making it a safe and delicious choice for gluten-sensitive eaters.
Can I prepare the sauce in advance?
Yes! The Romesco sauce actually tastes better after resting for several hours or overnight as the flavors meld beautifully.
What wine pairs well with this dish?
Try a crisp, unoaked white wine like Albariño or Sauvignon Blanc; both complement the smoky and tangy flavors without overpowering the cod.

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: If using fresh red peppers and tomatoes, roast them in the oven at 400°F (200°C) for about 20 minutes until charred. Remove skins, seeds, and stems from peppers and peel the tomatoes.
- Blend the Sauce: In a food processor or blender, combine roasted peppers, tomatoes, almonds, garlic, red wine vinegar, smoked paprika, and olive oil. Blend until smooth, adding 1-2 tbsp water to adjust consistency. Season with salt and freshly ground black pepper to taste. Set sauce aside or refrigerate if preparing ahead.
- Preheat the Grill: Heat your grill to medium-high heat (approximately 400°F/200°C). Lightly oil the grill grates or brush the cod fillets with olive oil to prevent sticking.
- Season the Cod: Season the cod fillets evenly with salt, freshly ground black pepper, and lemon zest if using.
- Grill the Cod: Place the seasoned fillets on the grill and cook for about 3-4 minutes per side, until the fish flakes easily with a fork. Cooking time will depend on the thickness of the fillets.
- Serve: Remove the cod from the grill and place on serving plates. Spoon a generous amount of homemade Romesco sauce over each fillet. Garnish with chopped fresh parsley and serve immediately for best flavor.
Notes
- Roasting the red peppers and tomatoes enhances the smoky flavor of the Romesco sauce, but jarred roasted peppers and canned fire-roasted tomatoes are convenient substitutes.
- If you prefer a nuttier sauce, try using hazelnuts or walnuts instead of almonds.
- Adjust water quantity when blending the sauce to achieve your preferred consistency.
- Ensure your grill grates are well oiled to prevent the delicate fish from sticking.
- Cooking times may vary depending on the thickness and freshness of the cod fillets.
- Leftover Romesco sauce can be stored in the refrigerator for up to 3 days and used as a dip or spread.
