Preheat the oven to 400 F degrees. Prepare a fresh wild Branzino by rinsing the fish with clean water and de-scale. Pat the fish dry with a paper towel and place it on a cutting board. Using a sharp knife, cut a few slits on the bronzini skin on both sides and set aside.
In a small bowl, whisk together the olive oil or avocado oil and the salted lemon spice blend until combined well.
Prepare a 13-inch or longer roasting pan or iron large skillet and line with 2 layers of aluminum foil. Pour half of the oil and spice marinade onto the aluminum foil. Use a spoon or spatula to spread if needed. While this recipe calls for lemon seasoning which also has lemon zest and black pepper with some dried herbs, can replace it with fresh lemon slices and herbs.
Place fish on top of the oil marinade and rub the cavity and skin with the oil marinade.
Drizzle the rest of the oil mixture onto the fish and bring the ends of the foil and close them completely so the moisture wouldn't escape.
Place it in the middle rack of the oven and bake for 20-30 minutes* until fully cooked. If you prefer crispy skin on top, open the foil wrap and place it in the broiler for a few minutes.
Remove from the oven and fillet bronzini. Serve the skin side up with a side of roasted cherry tomatoes, onions, fingerling potatoes, crusty bread, and salad. Garnish with fresh herbs.
