Score it. Oil it. Don't touch it.

Yes, you can absolutely grill a whole branzino directly on the grates, and it’s the way to go. The trick is prep and patience, not technique.

Start with clean grates (scrub while hot), then get them screaming hot. Oil the fish generously—both outside and inside the cavity—before you put it on. Score the skin three or four times on each side, down to the bone. This lets heat penetrate and keeps the skin from curling up. Season with salt and pepper inside and out, maybe some lemon slices and herbs in the cavity.

Put the fish on the hot grates and leave it alone. No moving, no peeking. After about 4-5 minutes (depending on size), you’ll see the edges turning opaque and the skin releasing. A thin metal spatula is your friend here. Gently lift to check—if it sticks, it’s not ready. Flip once, cook another 4-5 minutes, and you’re done. The skin should be crispy and the meat flaky.

Don’t try to flip too early, and don’t use tongs (they’ll break the fish). A fish spatula or two wide spatulas work better. And for branzino specifically, the skin is thin and tasty—no need to peel it off.

If you’re worried about sticking, you can oil the grates too, but honestly, a well-oiled fish on hot clean grates is enough.
