In a medium bowl, whisk together melted butter, olive oil, lemon juice, Worcestershire sauce, Dijon mustard, honey, garlic powder, onion powder, salt, and pepper.
Pat the salmon dry and place it in a shallow dish or resealable bag.
Pour the marinade over the salmon and ensure it's fully coated. Marinate for at least 30 minutes.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Bake the marinated salmon for 12-15 minutes until cooked through and flaky.
Let it rest for a few minutes before serving and garnish with fresh parsley.
