In a small bowl, combine the paprika, onion powder, garlic powder, salt, thyme, black pepper, and chili powder. For a spicier fish filet, add more chili powder or a pinch of cayenne pepper.

Heat the butter and oil in a cast iron skillet over medium high heat. Once nice and hot, add the fish in a single layer. Cook for 2 - 4 minutes (depending on the thickness of filet) on each side and carefully flip to cook on the other side for 3-4 minutes. A fish spatula works best to keep the fish from breaking. Serve with fresh lemon or lime.
