Preheat the oven to 375 degrees, and line a baking sheet with tin foil, leaving excess to be big enough to fold over and seal the salmon completely.

In a small bowl, add melted butter, onion powder, crushed red pepper, smoked paprika, garlic, salt, pepper, and dried parsley. Mix until everything is combined.

Place salmon onto the prepared baking sheet. Pour the butter mixture over the salmon and spread it around the fish with a baking brush, coating evenly.

Fold the sides of the foil over the salmon tightly, and place into the oven and bake for about 20-25 minutes.

Open the foil and broil the fish for 3-4 minutes. Keep an eye on it to make sure it is not to burn.

Remove from the oven and let cool.
