Grilled Branzino with Tomato-Olive Salsa

Each forkful of grilled branzino with a tangy, briny salsa is pure Mediterranean summer. It is smoky and sweet, sharp and salty, bright and herby all at once.

My Family’s Grilled Branzino Recipe

My father-in-law, raised by the water in Elefsina, Greece, is a third-generation fisherman’s son and a fish-cooking expert in his own right. For years, every Sunday lunch was the same: grilled whole branzino. He would be waiting by the grill, ensuring we ate the fish hot and that the head went to me. It is my favorite part. His excitement, the smoke, the apron around his waist, the fish over the coals. That was our Sunday.

Naturally, he made sure I learned it all. Standing beside him at the grill, he passed down every tip he had. He taught me how to read the heat and keep the fish skin from sticking. The years have caught up with him now and his hands are not as steady, so these days I am the one who cooks it. Carrying his recipe forward feels like the least I can do for everything he taught me.

His version is simplicity itself. Nothing more than grilled branzino with ladolemono spooned over the fish. That is the perfect Greek marriage of olive oil and lemon. To give it my own small twist, I have added capers and a fresh tomato salsa. This is a nod to a Greek salad. The result is bright, briny, and just acidic enough to cut through the rich flavor of the branzino.

Best of all, a whole fish on the platter looks like a celebration but it is deceptively easy. This recipe is so simple, you could cook it on a weeknight. But it is also a beautiful centerpiece for a long, lazy weekend lunch, exactly the way my father-in-law has always served it.

Key Ingredients

Whole Branzino

Branzino is also known as Mediterranean sea bass. It has a mild flavor and white flesh. Buy your fish scaled and gutted, but with the head and tail intact. Ask your fishmonger to do this for you to save time and effort.

Parsley

Parsley is used in both the stuffing and the salsa. It adds freshness that complements the fish’s delicate sweetness.

Lemon

I add lemon to the cavity of the fish. This neutralizes any fishy aroma while adding citrus perfume and flavor.

Rosemary

Piney, earthy rosemary pairs well with lemon and fish.

For the Tomato-Caper Salsa

Tomatoes are the base for the salsa. They deliver sweetness, a natural umami, and acidic brightness. Use ripe tomatoes as they are sweet and fruity. I like to dice them finely. My favorite options are Roma, heirloom, or cherry tomatoes.

Red onion adds a sweet profile, a pop of color, textural crunch, and a mild flavor to the topping. Finely dice it.

Garlic adds loads of flavor, providing a sharp and peppery note.

Extra virgin olive oil coats the fish preventing it from sticking to the grill. It also adds richness to the salsa. Use an early-harvest oil for its grassy, peppery notes, which pair wonderfully with the balsamic vinegar.

Capers give the salsa a briny tang and subtle tartness. These too are rich in umami, and they balance the natural sweetness of the tomatoes.

Kalamata olives add a slightly sharp yet deep flavor and earthy contrast. These winey, purple olives give the salsa a great flavor. Feel free to omit olives if you only want to add capers or vice versa. If you do add them, they must be pitted and finely chopped.

Balsamic vinegar brings a complex sweet and sour undertone to the salsa. I prefer a premium-aged balsamic because it is thicker and more syrupy. A standard everyday balsamic is also fine. It offers a mellow yet fruity tartness that pairs wonderfully with the tomatoes.

How to Make Grilled Branzino

Make the Salsa

In a bowl, combine the finely diced tomatoes, onions, olives, capers, minced garlic, and parsley. Add the olive oil, balsamic vinegar, and a pinch of salt. Toss gently and set aside at room temperature while you cook the fish.

Prep the Fish

Pat the scaled and gutted branzino completely dry, inside and out. Cut 2 to 3 shallow diagonal slashes into the thickest part of each side. Rub all over with olive oil and season generously with salt, inside the cavity, over the skin, and into the slashes. Stuff the cavity with lemon slices, parsley, and rosemary sprigs.

Prep the Grill

Preheat a gas grill to medium-high, 400 to 450 degrees Fahrenheit, with the lid down for 10 to 15 minutes. Scrub the grates clean, then oil them well. Dip a folded paper towel in oil, hold it with tongs, and wipe the grates.

Grill the First Side

Lay the fish on the hot grates. Close the lid and cook undisturbed for 7 to 10 minutes, until the skin is seared and releases naturally. Resist the urge to move it earlier. The skin needs time to sear and will release naturally when it is ready.

Flip and Finish

Gently turn the fish once with a wide spatula. Close the lid and grill another 7 to 10 minutes. The fish is done when the flesh at the thickest part is opaque and flakes easily. A thin knife should slide to the bone with no resistance. With an instant-read thermometer, you are looking for 145 degrees Fahrenheit at the thickest point.

Serve

Transfer to a platter and rest for 1 to 2 minutes. Remove the head, lemon wedges, and cavity herbs if preferred. Spoon the tomato-and-caper salsa generously over the top, letting the juices run into the cavity. Serve immediately.

How to Prep the Fish

A little prep here is the difference between fish that releases cleanly with crisp skin and fish that tears and sticks. Do not skip it.

Make sure it is scaled and gutted. If your fishmonger has not done it, scrape off the scales under cold running water. Work from tail to head with the back of a knife. Rinse the cavity well. Pull out any remaining bloodline along the spine.

Pat it dry, inside and out. This is the single most important step for crisp skin. Surface moisture steams rather than searing. Wet skin is what sticks to the grates. Use paper towels to blot the cavity and skin thoroughly.

Score the skin. With a sharp knife, make 2 to 3 shallow diagonal slashes, about half a centimeter deep, into the thickest part of each side. Cut down toward the bone. This helps the fish cook evenly, allows seasoning to reach the flesh, and prevents the skin from buckling on the grill.

Season generously. Rub the whole fish with olive oil, then season all over with salt. Season inside the cavity, over the skin, and into the slashes.

Stuff the cavity with lemon slices and some fresh herb sprigs. Do not overpack it. You want the cavity to close comfortably.

How to Prep the Grill

The grill setup matters as much as the fish. Most fish always sticks to my grill problems are grill-prep problems.

Preheat to medium-high, about 400 to 450 degrees Fahrenheit, with the lid down, for at least 10 to 15 minutes. A fully preheated grate is essential. If fish are dropped onto a lukewarm grate, they will grab and tear.

Scrub the grates clean with a grill brush while they are hot. Any stuck-on residue from last time gives the skin something to cling to.

Oil the grates well, right before the fish goes on. Fold a paper towel into a thick pad, dip it in vegetable oil, and holding it with long tongs, wipe the grates several times until they look glossy. This builds a quick non-stick layer. Never pour oil directly onto the flames.

How to Debone Whole Grilled Fish

You can serve the fish whole, head and tail intact. Or you can remove the head before serving. Or you can fillet it. Eating and serving a whole cooked fish is simpler than it appears once you understand the structure. A branzino’s bones are large and straightforward, making it easy to lift off the flesh in tidy fillets. Here is how to do it.

Get ready. Letting the fish rest for a few minutes after cooking firms up the flesh so it separates from the bones cleanly. While it rests, assemble a serving plate, a separate plate for the bones, a spoon, and a flexible spatula.

Score the fish. Run a knife gently down the center line of the fish, from head to tail, along the backbone ridge. Then make a cut just behind the head and another just in front of the tail. You have now outlined the top fillet.

Lift off the top fillets. Slide your spatula under the flesh and lift it away from the bones in either one piece or two pieces. One piece from the top of the spine, one from the belly side. Use the spoon in your other hand to assist. The flesh should release easily. Set these portions aside.

Remove the spine. This is the magic step. Lift the tail and gently peel the entire skeleton, backbone, ribs, head, and tail all attached, up and away from the bottom fillet. It should come away as one connected frame, leaving the bottom fillet clean underneath. Discard the whole skeleton into your bone plate. But do not miss the cheeks just below the eyes. They are the sweetest morsel on the whole fish.

Finish and serve. Use the spoon to scoop away any stray bones on the belly side of the fillets. With the bones gone, both fillets are ready to serve.

Grilled Branzino Tips

My father-in-law’s tips are worth heeding when grilling fish.

Salt the salsa lightly. The olives and capers are already salty, so taste before adding more.

Dry fish equals crisp skin that will not stick. If you do only one thing, blot the fish thoroughly before oiling it and placing it on the grill. Wet skin both steams and sticks.

Hot grate, oiled grate, patient cook. After drying, there are three keys to fish that will not stick. A fully preheated grill, well-oiled grates, and leaving the fish alone until the skin has seared. If the fish will not lift, it is not ready. Wait another minute and it will release on its own.

Use the right tool to flip. A thin spatula, or two spatulas for a larger fish, makes turning a whole fish far less nerve-wracking than tongs. Tongs will only tear the fish.

Do not overcook it. Fish goes from perfect to dry quickly. Pull it at 145 degrees Fahrenheit. Carryover heat will finish the job as it rests.

A grill basket is great insurance. If you are nervous about sticking or working with a more delicate fish, a well-oiled closing grill basket lets you flip the whole thing in one confident motion.

Make It Your Own

No branzino? Any whole, mild, flaky white fish works. This includes red snapper, black sea bass, striped bass, or small trout. Adjust the grill time up or down based on size.

Swap the herbs. No fresh parsley or rosemary for the cavity? Use thyme or dill.

Change up the salsa. Add finely diced cucumber or red pepper.

No grill, no problem. This works under a hot broiler or on a stovetop grill pan with the same timing. It is just as delicious.

What to Serve with Grilled Branzino

Because the fish and salsa are so fresh and bright, I like to keep the sides simple. A tray of Greek roasted lemon potatoes, a Greek rice dish, or a platter of grilled vegetables is great. They soak up the salsa juices beautifully.
