Ingredients
Here’s what you’ll need to make this culinary marvel come to life:
- 4 fresh cod fillets (about 6 ounces each, skinless)
- 2 tablespoons olive oil (plus more for drizzling)
- 1 teaspoon smoked paprika
- Salt and pepper, to taste
- 1 lemon (for zest and juice)
For the Romesco Sauce:
- 1 red bell pepper
- 1/2 cup roasted almonds (unsalted)
- 2 medium cloves garlic (fresh is key for a punchy flavor!)
- 1/2 teaspoon red pepper flakes (optional, for heat)
- 3 tablespoons red wine vinegar
- 1/4 cup olive oil
- Salt and pepper, to taste
Note: If you’re short on time, you can look for a store-bought Romesco, but trust me—nothing beats homemade!

Step-by-Step Instructions
- Prepare the Romesco Sauce: Start by roasting the red bell pepper. You can do this over an open flame, under the broiler, or on a hot grill. Char it until the skin is blistered, about 10-15 minutes. Once done, place it in a bowl and cover it with plastic wrap to steam for 10 minutes. This will help loosen the skin.
- Peel the Pepper: After it has cooled a bit, peel away the skin, remove the seeds and stem, and chop it coarsely.
- Blend the Sauce: In a food processor, combine the chopped roasted pepper, almonds, garlic, red pepper flakes (if using), red wine vinegar, and a pinch of salt and pepper. Pulse until chunky, then slowly drizzle in the olive oil while blending until you reach your desired consistency. Taste and adjust the seasoning.
- Prep the Cod: While the Romesco sauce is coming together, preheat your grill to medium heat. Pat the cod fillets dry and season both sides with olive oil, smoked paprika, salt, and pepper. Zest the lemon over the fish to give it a fresh brightness.
- Grill the Cod: Place the seasoned cod fillets on the grill and cook for about 4-5 minutes per side, depending on the thickness. The fish should flake easily with a fork when it’s done. Make sure not to overcook it or it may dry out—keep an eye on it!
- Plate It All Together: Serve the cod fillets drizzled with the Romesco sauce and a squeeze of fresh lemon juice for that extra zing!
Pro Tips & Variations
Want to jazz this dish up even more? Here are a few playful suggestions:
- Add More Depth: Try adding a pinch of cumin or coriander to your Romesco sauce for an extra layer of flavor.
- Make it Creamy: If you want a creamier sauce, blend in a spoonful of Greek yogurt or mayonnaise.
- Change Up the Fish: This recipe isn’t just for cod! You can substitute with other firm white fish like haddock or even salmon for a richer taste.
- Go Green: For a veggie option, grill some fresh asparagus or zucchini on the side—drizzle them with the Romesco sauce as well!
Cooking should always be fun, so don’t be afraid to experiment until you find your own twist on this recipe!
Serving Suggestions
To truly make this dish shine, I like to serve it with a few sides that balance the rich Romesco. A simple green salad with a light vinaigrette adds a refreshing bite. Or perhaps some couscous or quinoa seasoned with herbs for a lovely texture. You could even throw together some crusty garlic bread to soak up all that delicious Romesco sauce! Picture this: a sunny table set outside, laughter ringing in the air, and plates filled with vibrant colors and flavors. Now that’s the essence of a perfect meal!

Storage Tips
If you’re lucky enough to have leftovers (though I doubt they’ll last long!), here’s how to store and reheat them:
- Refrigerate: Place the leftover grilled cod in an airtight container and store in the fridge for up to 2 days. The Romesco sauce can also be kept separately for the same amount of time.
- Freeze: While I recommend eating it fresh, if you must freeze the cod, wrap it tightly in plastic wrap and place it in an airtight container—best used within a month.
- Reheat: Gently reheat the cod in a skillet on low heat to keep it from drying out. You can also warm up the Romesco sauce in a small pot over low heat until warmed through. Just don’t let it boil!
FAQs
Can I use frozen cod for this recipe?
Absolutely! Just make sure it’s fully thawed before grilling. Frozen fish may take a few extra minutes to cook, so keep an eye on it.
What if I can’t find red bell peppers?
Don’t sweat it! You can use jarred roasted red peppers instead—they’re a great substitute and super handy for quick meals.
Is Romesco sauce spicy?
The sauce isn’t necessarily spicy, but the red pepper flakes can add a bit of heat. Feel free to adjust or omit them based on your preference!
How can I make this dish more filling?
Serve it over a bed of fluffy rice, or add some grilled potatoes on the side for a heartier meal. You could also toss in some roasted vegetables for a nice balance.
Can I make the Romesco sauce ahead of time?
Certainly! You can make it a day in advance and store it in the fridge. Just give it a quick stir before serving, as the flavors will meld beautifully overnight.
