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

Place the salmon fillets in a baking dish and pour the marinade over them. Let them marinate for at least 15 minutes.

Preheat the oven to 400°F (200°C). Bake the marinated salmon for 15-20 minutes, or until cooked through and flaky.

Garnish with lemon slices and additional dill before serving.
