Mix paprika, black pepper, thyme, basil, garlic powder, onion powder, oregano, and cayenne pepper on a large piece of wax paper.
In a small saucepan over medium heat, melt butter with oil. Brush both sides of snapper fillets with butter oil mixture; reserve remaining butter oil mixture. Coat both sides of fillets with paprika mixture.
Heat a large cast iron skillet over high heat until a drop of water sizzles on it.
Drizzle 1/2 of the remaining butter oil mixture on one side of fish fillets. Place fillets butter side down in the hot skillet; cook until deeply browned, about 5 minutes. Drizzle remaining butter oil mixture over fillets and flip over. Cook until fish is browned and flakes easily with a fork, about 5 minutes more. Season with salt.
