This Grilled Cod with Romesco Sauce is a flavorful and healthy dish featuring tender grilled cod fillets served with a rich and smoky Romesco sauce.
Grilled cod is one of those dishes that proves seafood doesn’t need to be complicated to be delicious. Light, flaky, and mild in flavor, cod is the perfect canvas for bold sauces. And few sauces bring as much character to a plate as Romesco. With its smoky, slightly sweet, and tangy flavor, Romesco transforms a simple piece of grilled fish into a restaurant-worthy meal.
Romesco sauce originates from Catalonia, Spain, and is traditionally made with roasted red peppers, tomatoes, garlic, almonds, olive oil, and a touch of vinegar. The result is a thick, rustic sauce that pairs beautifully with grilled meats, vegetables, and especially seafood. Its rich texture and deep flavor come from toasting and blending the ingredients, giving it a satisfying complexity that’s hard to beat.
When paired with grilled cod, the contrast is perfect. The clean, delicate flavor of the fish balances out the punchy intensity of the sauce. Grilling adds a bit of char and smokiness to the cod, which plays nicely with the nuttiness and depth of the Romesco. Together, they form a dish that feels special but not fussy.
This pairing also lends itself to a wide range of sides. You can keep it fresh with a simple green salad, roasted vegetables, or grilled asparagus. Or go heartier with a side of potatoes or crusty bread to mop up any leftover sauce. Either way, it’s a meal that comes together easily but delivers big on taste.
Grilled cod with Romesco is ideal for those who want something light yet satisfying, fresh yet full of bold flavor. It’s just as suited for a casual weeknight dinner as it is for entertaining guests. And the best part is how little effort it takes, just quality ingredients, a hot grill, and a sauce that does all the heavy lifting.
If you’re looking to mix up your seafood routine, this dish is a standout. It’s balanced, vibrant, and a reminder that simple meals can still make a lasting impression.

Is romesco sauce really that good? Never have heard of it before! I’ll stick to ketchup for my fish.
I had my doubts about the combination, but it surprisingly worked well. A bit too oily for my taste though.
Loved the flavor! It was quick and easy to prepare. A keeper for my family dinners!
Cod is ok. Sauce tastes like what my aunt puts on everything lol. Would make again, but maybe with salmon next time.
I tried this recipe but my cod turned out dry. Maybe I grilled it too long? Not sure if I’ll try again.
Wow!! I’m gonna try this tonight! Been looking for healthy recipes!
Tried this tonight but my fish got burnt 😭. Might need a rescue for my grilling skills.
Grill n’ chill! This was amazing, will be adding it to my weekly menu!
The cod turned out super dry. Maybe I cooked it too long? Not sure if I’ll try this again.
Sorry to hear that! Cod can get dry if cooked too long. Maybe try less time next time?
I think you might be overcooking it! It’s usually quick on the grill, like 4 mins max. Don’t give up!
The sauce was too nutty for me. Prefer my cod with just lemon.
I totally get it! I also love a simple lemon on my fish. Sometimes less is more!
The sauce tastes like something fancy from a restaurant. I used less garlic because I’m sensitive and it was still bold. 10/10 would serve to guests.
I’m kinda surprised it’s that good—romesco usually feels like a lot of work. But grilling cod is easy and the sauce is bold even with less garlic. Nice.
Yes!! I made this and it totally tastes restaurant-level. The sherry vinegar + smoked paprika combo is chef’s kiss.
I made this and it was meh. The romesco came out kinda bitter to me, maybe from the almonds? I’m not sure. Also grilling fish that long feels risky.
Super easy recipe! Took me under 30 minutes and my family loved it!
Pretty solid recipe. I had to grill a bit longer because my fillets were thicker, but the sauce covered it nicely. The smokiness from paprika is legit.
Interesting… I think 4-5 minutes on each side is gonna dry it out. Cod’s pretty delicate, so I’d do like 2-3 min and call it. Also, is it sherry vinegar or sherry wine? I used the wrong thing once 😅
Glad it worked out! Thick fillets always throw off the timing—4-5 min/side is more like a guideline. The paprika smokiness is the whole vibe of romesco.
Good but not great. I prefer my cod baked, to be honest.
Grilled cod, who knew? I didn’t think fish could taste this good! 😋
5 stars! I love how healthy and tasty it is. Perfect for summer!
Made this last night—cod was flaky and the romesco tasted like a fancy restaurant. Only tweak: I added a tiny squeeze of lemon at the end. So good!
The flavors were okay but too complicated for me. I’m just a simple cook!
Absolutely delicious! The romesco sauce adds such a great flavor to the cod. Will definitely make this again!
I followed the recipe and it came out bland. Maybe my grill temp was wrong? Also I accidentally forgot the garlic 😑—but still, not great.
Oof—no garlic would definitely make the romesco taste flatter. Also, cod is super picky: if the grill is too low it can come out kind of bland/soft, but if it’s too high it can dry out and lose flavor. Next time add a tiny pinch more salt right before serving (or a squeeze of lemon).
It was okay, but honestly, I’ve had better fish dishes. I probably won’t repeat it.
I tried this but ended up burning the fish. Maybe grill it on lower heat? Not super happy.
Easy to follow recipe! Will make it again for sure 🙂
Romesco sauce, huh? What’s that? Isn’t it just a dip? I didn’t like the taste. Cod was fine tho.
Is it just me, or does this seem like a lot of ingredients for fish? I’m skeptical.
The sauce is amazing, but the cod timing depends on thickness. Mine were thin and 4–5 minutes each side was too much—still edible though.
Good point—cod really does vary a lot by thickness. 4–5 minutes per side is a decent starting range, but I always check for that opaque/flaky look instead of relying only on the timer. Glad yours was still edible!
Excellent recipe! I added some spice to the Romesco and it was even better. Yummy!
The combo of cod and the sauce was just okay. I’ve had better fish recipes. 😕
Love it! Made it for my fam and they are begging for more.
Yum! Cod is my fav! Can you use another type of fish?
Whoa, I thought Romesco was a type of fish! Turns out it’s a sauce. 🤷♂️
Romesco sauce? Never heard of it. Is it supposed to taste like BBQ?
I couldn’t get the sauce to blend right, it was chunky. What’s the secret to a smooth romesco?
Easy to follow!! But I messed up on the sauce, it turned out too chunky.
This was a hit at my dinner party! The Romesco sauce adds such a unique flavor. Will definitely make again!
I’m so glad you enjoyed it! The Romesco sauce really does elevate the dish.
This was surprisingly restaurant-y. The romesco is smoky and bright, and the cod stayed flaky without drying out. I followed the 4-5 min per side and it came out perfect.
This recipe is amazing! The Romesco sauce adds such a great flavor to the cod. My family loved it!
Sounds fancy, but I don’t know if my family will like this. They are more into plain stuff.
I totally agree! The Romesco sauce really takes it to the next level. I’ll definitely try this again.
Meh. Forgettable. 😐
Really? I loved it! The combination of cod and that sauce was fire! 🤤
I thought it was pretty tasty! The Romesco sauce added a nice flavor. Maybe you didn’t season it enough?
This grilled cod is to die for! The Romesco sauce makes it so delicious.
I’m skeptical about grinding peppers and almonds into a “smooth” sauce—mine was more chunky than silky. Still tasty, but I’d blend longer or blend hotter?
I thought cod was a type of chicken? I guess it’s fish… Anyway, I still ate it and it tasted alright.
Cod is so dry if you grill it. I prefer baking it instead.
Grilled cod is gross and slippery. Why would anyone put that sauce on it? No thanks.
Romesco? What is that? Sounds fancy but I’m just a simple guy. Cod is good tho.
This was a flop! Cod is too bland, and the sauce wasn’t even good. What are people raving about?
I totally disagree! I think the Romesco sauce brings everything together. Maybe you just didn’t season it well?
Grill cod for 4-5 mins? Nah… more like 10 mins on high heat for me!
Pretty tasty, but my sauce was way too thick after blending. I had to add a splash more olive oil to loosen it. Still totally worth it.
This recipe is awesome! The romesco sauce really makes the dish pop.
Simple and tasty! I used frozen cod fillets and it turned out great. Easy to follow!
Glad to hear it turned out good! Frozen cod is such a lifesaver sometimes. I’ll have to try the Romesco sauce too!
Not bad. I used jarred roasted red peppers and it tasted okay, but not as deep as when I’ve made romesco before. Maybe next time I’ll roast them myself.
Made this last night—romesco is so flavorful. I used a little extra smoked paprika and it really popped. Cod stayed flaky and not dry.
I didn’t have sherry vinegar, used lemon juice instead. Still tasted good!
I don’t know about this recipe. Fish with bells peppers is weird. I prefer fried fish.
Sooo good! I added a pinch of red pepper flakes for a kick.
Cod grill timing is everything! Mine went a little too long and got dry, but the flavor was on point. Next time I’ll pull it at 4 minutes per side.
I tried it but used different fish. It didn’t work out same. Cod is better, I guess!
Not sure if I did it right but the fish was too dry. Maybe I overcooked it? Gonna try again and see!
I tried this but it was too bland for me. Needs more seasoning!
I think it really depends on your taste buds! I added more spices and it was delicious! Maybe try that next time?
I messed up and put in too much vinegar… sauce tasted kinda sharp. I balanced it by adding more almonds and olive oil. Lesson learned 😅
Oof, too much vinegar can definitely make romesco taste sharp 😅 But hey—you adjusted with almonds and olive oil, that actually makes sense. Next time just start with less vinegar and taste.
Sharp?? I would just add a little more roasted pepper too. Still sounds tasty though—romesco is kinda forgiving as long as you keep the balance right.
Why do people think grilled fish is fancy? It’s just fish on a grill.
This recipe is great but where I live, we don’t have cod!! Can I use tilapia instead? Did anyone try that? 🤔
This was restaurant-level good. The romesco sauce tastes smoky and bright at the same time—perfect with cod. I didn’t have smoked paprika so I used regular and it was still great.
This recipe is fantastic! The Romesco sauce adds a delicious kick to the cod. Will definitely make it again!
I’m glad you loved it! The Romesco sauce is such a game changer for fish. Did you try it with any other dishes?
I dunno… sounds good but how can you be sure it tastes so good? Did you really make it or just tasting from someone else?
This was delicious! The Romesco sauce really made it pop. 5 stars!
I totally agree! That sauce is incredible, I could eat it on everything!
Romesco sauce? I thought it was just spicy ketchup! Really unsure about that.
Simple and delicious! 😋 My family loved it! Just made some rice on the side, perfect!
I’m so happy to hear that your family enjoyed it! The rice sounds like a great addition too! 😊
I’m skeptical about blending roasted peppers + almonds for sauce, but wow—actually it worked. I added a pinch of chili flakes because I like heat.
Wait… peppers + almonds blended into a sauce? That’s wild. I feel like it would be too thick or nutty, but if it worked for you maybe I’ll try. Did you use blanched almonds or just normal toasted ones?
Honestly that combo sounds weird on paper, but I love that you tried it anyway. Romesco is kind of magic like that—great call adding chili flakes!
This dish was absolutely delicious! The Romesco sauce added a nice kick. Will definitely make again!
I’m so glad you enjoyed it! The Romesco sauce really does elevate the dish. Can’t wait to try it myself!
Easy and delicious! The cod flaked perfectly. I like that it’s not complicated. —Honestly I could eat the romesco by itself.
Yes!! I made this last night and the romesco is dangerously good—could 100% eat it with a spoon too. The cod was flaky and not dry at all.
Not bad, but I think 4-5 minutes per side is kinda long? Mine got a little overdone on the grill. Also I blended it and it was thick—next time I’ll add more olive oil or even a splash of water. Still flavorful though!
This is too complicated for me. I thought it was just grilling fish.
Too much ingredients for a simple fish dish. Just grill it and eat!
I think the sauce adds so much flavor! Don’t skip the Romesco, it’s delicious. 🔥
I tried it, but my fish got too dry. Maybe I left it on the grill too long?
Not bad, but why sherry vinegar? I accidentally used regular vinegar and it was still okay. Also 2 cups peppers seems like a lot unless you’re roasting a ton of them.
Isn’t romesco sauce from Spain? Just curious.
Easy to make but I didn’t have sherry vinegar so I used regular vinegar… still tasted good!
Great job improvising! Regular vinegar can work in a pinch. I love how cooking allows for creativity!
Can I use another fish? Don’t have cod at home.
I dunno, isn’t cod like special or somethin’? I mean, can you just swap fish? What if it tastes weird?
You can definitely use another type of fish! Salmon or tilapia might work well. Just keep an eye on the cooking time, they may cook differently.
Eh, I guess it’s okay, but I don’t think I would make it again.
Wow, this sauce is nice! Never thought to use almonds in a sauce. 👍
Romesco is my weakness, so I was excited. I used jarred roasted peppers in a pinch and it still tasted great. Next time I’ll toast the almonds a bit longer.
This was amazing! The Romesco sauce really brought out the flavors of the cod. Will definitely make again!
Not bad. I don’t have sherry vinegar, I used apple cider. Still worked.
Good to hear it worked! Apple cider vinegar can be a nice twist. I might try that next time too!
Easy to follow and delicious! The cod came out perfectly grilled. Just adjust the salt a bit!
Grilled cod is the best! Very easy with simple ingredients. Will make it again!
Cod on the grill can be tricky. Mine stuck a bit even though I oiled it. I think next time I’ll use a grill mat or oil the grates better. Sauce tasted amazing!
I’m usually skeptical of “blend it all” sauces, but this one actually worked. Smooth, flavorful, not too sharp even with the sherry vinegar.
Pretty solid combo. I grilled a bit too long (oops) so my cod was closer to medium-firm than flaky, but the sauce saved it. Next time I’ll watch the 4–5 min closer.
Medium-firm cod sounds kinda sad, not gonna lie, but if the sauce saved it then fair enough. I always struggle with timing—mine usually turns tough if I blink. Any tips for checking doneness without overthinking?
Agree—Romesco really bails out anything that’s a little overcooked. I’ve done the same “oops” with cod before 😅. Next time you’ll nail the 4–5 min.
Not my favorite. The sauce was too strong and the cod a bit bland. 2 stars.
I actually loved the sauce! It gives such a nice kick to the cod. Maybe you just didn’t blend it well enough? 5 stars from me!
Really? I thought the sauce was a bit too much too. But the cod was nice for me. I’d say 3 stars overall.
I followed it pretty closely, but grilling 4-5 minutes per side felt long for my grill. My cod came out a bit overcooked and flaky in a not-so-great way.
Maybe your cod was just too thin? 4-5 mins per side seems like way too much though. I grill mine like 2-3 mins and it’s perfect. Also flaky in a bad way = either high heat or leaving it too long… sorry friend 😕
Ahh that’s a bummer. I’ve had the same issue when the grill runs hotter than “medium-high.” I start checking around 3 minutes per side for thinner fillets—once it flakes with a fork but still looks a little glossy, it’s done.
Good, but I like my fish with lemon. Just a suggestion.
Lemon sounds great! I might try that next time. Thanks for the tip!
Loved the romesco—smooth, smoky, and tangy. The cod cooked up perfectly on the grill and didn’t dry out. Definitely making this again.
I don’t really get the hype about Romesco sauce. Seems kinda fancy for just fish, right?
Not gonna lie, I was skeptical about blending almonds + peppers into something smooth. But the texture is actually great and tastes restaurant-y.
I had the same hesitation—peppers + nuts can sound weird—but Romesco is supposed to be that creamy-spicy combo. Glad it worked out!
Um… could you just use regular store-bought red pepper spread? Like the stuff in jars? I feel like it would work, but I’m not sure.
Who even eats fish? Just stick to chicken people! 😂
This recipe is amazing! The romesco sauce is to die for!
YUMMMM! Put more garlic in the sauce and wow! Flavor explosion!!
Yum! I replaced almonds with walnuts cause I had no almonds. Still turned out great!
Walnuts? Really? That’s a bit different but if it worked for you, then awesome! I might try that too, thanks for sharing!
Isn’t the recipe supposed to have almonds? Walnuts are way different. I don’t know about that, maybe try it again?
Quick question: do you need a food processor? I didn’t have one and I just mashed everything with a fork. It was… fine? Kinda rustic. Won’t lie, I prefer smoother sauces.
I liked it a lot, but my sauce was a little thick—next time I’ll add a splash more olive oil or maybe a bit of water to smooth it out. Flavor was still great though.
I don’t get it… can I just use regular peppers? Why roasted?? Seems unnecessary
The romesco is delicious, but mine was too thick—maybe I used less olive oil than called for. Next time I’ll loosen it with a splash more oil or water.
The smoked paprika is a game changer! I love this recipe.
Meh, I’ve had better cod recipes. This one was too bland for my taste.
I actually loved it! The Romesco sauce added so much flavor. Can’t please everyone, I guess!
My cod stuck to the grill a little. I think I didn’t oil the grates enough. Sauce was still amazing though, like roasted peppers in a bowl.
Not bad, but my sauce turned out a little thick and I had to add extra olive oil to blend it smooth. Flavor was solid though.
Not gonna lie, I didn’t have sherry vinegar so I used regular white vinegar… big mistake. Still edible, just tasted kinda harsh.
I didn’t have sherry vinegar, so I used apple cider vinegar. Tastes a little sharper, not bad, but it wasn’t the same vibe.
Why grill cod? wouldn’t it stick? I swear mine broke apart when I tried flipping. Flavor still good though, but grilling fish is stressful.
4-5 minutes per side feels short to me. I followed it anyway and my first piece was underdone. Maybe my grill runs cool. Otherwise flavor is good.
So easy and so fancy. My family kept asking how I made the sauce like that. I served it with rice and it was gone fast.
Right? I made this once and my family acted like I’m some kind of chef 😄 The romesco sauce is the whole magic. What kind of rice did you use?
