For the fish

  • 1 whole branzino
  • half a lemon
  • half a small onion
  • fresh dill (or your favorite herbs)
  • olive oil
  • salt and pepper

For the lemon caper sauce

  • 1 tablespoon caper
  • 1 tablespoon lemon juice
  • 2 tablespoon extra virgin olive oil
  • lemon zest (optional)
  • 1/8 teaspoon salt


  • Preheat the grill, clean and oil the grates well, prepare it for medium-high heat.
  • Prep the fish while the grill is preheating.
  • Wash the fish and pat dry (I usually have my fishmonger scale and gut the fish). Score both sides of the fish. Massage it with 1/2 tablespoon of olive oil and sprinkle both the outside and the cavity of the fish generously with salt and pepper.
  • Cut lemon and onion into thin slices. Stuff lemon slices, onion slices, and dill into the cavity of the fish.

  • When the grill is ready (remember it needs to be hot), place the fish on the grill and let it cook for 5-6 minutes.
  • When the fish no longer sticks to the grates, it's time to flip. Use a spatula to slide under the fish and together with a pair of tongs, flip it. Cook for another 5 minutes (amount of time depends on how big your fish is).
  • When the fish is fully cooked, transfer to a serving plate and follow the steps I mentioned earlier to cut it. Drizzle lemon caper sauce over it and enjoy.

For the lemon caper sauce

  • While the fish is cooking, put all ingredients to make the sauce into a bowl and mix well to combine.


If you don't have fresh herbs on hand, you can sprinkle dried Italian herbs generously into the cavity of the branzino.
