01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or aluminum foil for easy cleanup.
02 - Pat the fish completely dry inside and out using paper towels. Make diagonal cuts through the skin 3–4 times on each side to help the skin crisp evenly.
03 - Rub olive oil over the entire fish, including inside the cavity. Generously season with coarse sea salt and freshly ground black pepper, ensuring even coverage.
04 - Fill the fish cavity with lemon slices, fresh thyme sprigs, rosemary sprigs, and sliced garlic cloves, distributing them evenly throughout.
05 - Place the fish on the prepared baking sheet. Arrange so the skin faces up and remains exposed—avoid covering with excess oil or juices to ensure proper crisping.
06 - Roast in the center of the oven for 20–25 minutes until the skin is golden and crispy, and the flesh flakes easily when tested with a fork.
07 - Let the fish rest for 2–3 minutes before transferring to a serving platter. Garnish with chopped fresh parsley and serve with lemon wedges on the side.
