Preheat the oven to 400°F (200°C).

In a mixing bowl, combine olive oil, lemon juice, dill, garlic powder, salt, and black pepper.

Place the salmon fillets in a baking dish and pour the marinade over them, ensuring they are well coated.

Bake the salmon in the preheated oven for 12-15 minutes, or until the salmon flakes easily with a fork.

Remove from the oven and let it rest for a few minutes before serving.
