Rinse and pat dry fish.
Make 3 slits or more on both sides of the fish.
Make a seasoning mix by combining: melted butter, sea salt, pepper, garlic powder, Italian seasoning, and squeezed lemon juice.
Mix well and adjust to taste.
Place fish on a lightly oiled foil-lined baking sheet.
Brush fish with seasoning mix on both sides, inside the cavity, and inside the slits.
Insert fresh minced garlic or sliced onion and lemon slices inside the fish cavity.
Insert lemon slices into the slits.
Dust with additional paprika, salt, and dry parsley.
Bake in the preheated to 400°F oven for about 30 minutes or until fish flakes easily.
Drizzle with lemon juice and dripping from the seasoning. Garnish with fresh herbs (parsley) and serve.
