Ingredients You’ll Need

2 whole branzino (1 to 1 1/2 pounds each): Choose fresh fish if possible, as they offer the best flavor and texture.
2 tablespoons extra virgin olive oil: For rubbing the fish and achieving that beautiful grill char. Buy quality; it makes a difference!
1 lemon, thinly sliced into rounds: Adds a fresh zing inside the fish, balancing its rich flavor.
4 sprigs flat leaf parsley: Fresh herbs are key; feel free to substitute with cilantro for a different twist.
2 sprigs rosemary: This herb complements the fish beautifully. If you don’t have any on hand, thyme could work as well.
Kosher salt: This seasoning enhances the natural flavors. Regular table salt can be too salty, so use kosher for best results.
2 cups diced tomatoes (about 300g): Fresh tomatoes bring vibrant flavor to the salsa. If they’re out of season, high-quality canned tomatoes are a good alternative.
1/4 cup pitted kalamata olives, roughly chopped (about 40g): Their briny taste adds depth to the salsa.
1 tablespoon drained capers: These add a nice tang; if you’re not a fan, you could skip them for milder flavors.
1 small garlic clove, minced: Fresh garlic is essential for that aromatic flavor profile.
1/2 cup finely diced red onion: This brings sweetness and crunch to the salsa.
1 cup chopped parsley: Finesses the salsa with freshness. Flat-leaf is preferable for its flavor.
6 tablespoons extra virgin olive oil: This tops off the salsa, adding richness. Again, opt for quality.
2 teaspoons balsamic vinegar: This adds tanginess and a bit of sweetness to the salsa’s flavor.
Pinch kosher salt: To adjust the salsa if needed; always taste as you go!

How to Make Grilled Branzino with Tomato-Olive Salsa

Make the Tomato-Caper Salsa: In a bowl, mix together 2 cups diced tomatoes, 1/4 cup halved kalamata olives, 1 tablespoon drained capers, 1 minced garlic clove, 1/2 cup finely diced red onion, and 1 cup chopped parsley. Drizzle in 6 tablespoons extra virgin olive oil and 2 teaspoons balsamic vinegar. Toss the mixture gently and set it aside at room temperature while you cook the fish.
Prep the Fish: Pat each branzino completely dry, both inside and out. Carefully cut 2 to 3 shallow diagonal slashes (about 1/2-cm deep) into the thickest part of each side. Rub the fish all over with 2 tablespoons extra virgin olive oil and season generously with kosher salt, ensuring you season the inside cavity, skin, and into the slashes. Stuff the cavity of each fish with lemon slices, 4 sprigs of flat-leaf parsley, and 2 sprigs of rosemary. Let the fish sit at room temperature while you prepare the grill.
Prep the Grill: Preheat a gas grill to medium-high heat (400–450°F) with the lid down for about 10 to 15 minutes. Scrub the grates clean, then oil them well: dip a folded paper towel in oil, hold it with long tongs, and wipe the grates until they shine.
Grill the First Side: Carefully lay the branzino on the hot grill grates. Close the lid and cook undisturbed for 5 to 6 minutes, ensuring the skin sears nicely and releases easily from the grill.
Flip the Fish: Gently turn the fish once using a wide spatula. Close the lid and grill for another 4 to 6 minutes until the flesh is opaque, flakes easily at the bone, and reaches an internal temperature of 145°F at the thickest point.
Finish and Serve: Transfer the fish to a platter and let it rest for 1 to 2 minutes. If preferred, remove the head, then generously spoon the tomato-and-caper salsa over the top, allowing the juices to cascade into the cavity. Serve immediately and enjoy!

Storing & Reheating

To store leftover grilled branzino, place it in an airtight container in your refrigerator, where it will keep for up to 3 days. It’s best to store the salsa separately to maintain its fresh texture and flavor. If you’d like to freeze the fish, wrap it tightly in plastic wrap and place it in a freezer-safe bag for up to 3 months. To reheat, place the fish in a preheated oven at 350°F for 10-12 minutes or until warmed through, although this may alter the texture slightly. Adding fresh herbs as a garnish can refresh its presentation!

Chef’s Helpful Tips

Be cautious not to overcook the fish; it should be perfectly flaky but still moist.
If your grill marks are lighter, ensure your grill is hot enough before placing the fish on it.
Consider letting your fish rest a bit longer before grilling, as this helps retain moisture.
For maximum flavor, aiming for fresh, high-quality ingredients is key—especially the olive oil and fish.
You can make the tomato-olive salsa ahead of time; it only gets better as it sits.
If you have leftovers, consider flaking the fish into salads or pasta dishes—the flavor remains delightful!

Grilled branzino with tomato-olive salsa is undoubtedly a dish that brings a touch of the Mediterranean to your table. Its simplicity in preparation, combined with its impressive presentation, makes it perfect for any occasion. Feel free to experiment with the salsa, adding in your favorite ingredients or adjusting the flavors to fit your palate. Don’t hesitate to enjoy this delightful dish filled with fresh flavors and communal joy.
