Instructions

  1. Step 1: Preheat your oven to 400°F (200°C). Rinse the 1.5 lbs whole sea bream and pat dry with paper towels.
  2. Step 2: Place the sea bream on a baking sheet lined with parchment paper. Drizzle 3 tbsp of Istrian extra virgin olive oil over the fish, rubbing it evenly inside and out.
  3. Step 3: Insert 4 thinly sliced garlic cloves, 2 sprigs of fresh rosemary, and 2 sprigs of fresh thyme inside the cavity of the fish along with 3 lemon slices. Season the outside with 1 tsp sea salt and 1/2 tsp freshly ground black pepper.
  4. Step 4: Arrange the remaining lemon slices around the fish on the baking sheet. Roast in the preheated oven for 20-25 minutes until the flesh is opaque and flakes easily with a fork.
  5. Step 5: Remove from oven and let rest for 5 minutes before serving, spooning any pan juices over the fish for extra flavor.
