To create a delicious glaze for your dish, take a small bowl and mix together maple syrup, soy sauce, minced garlic, salt, and pepper.
Place the salmon fillets in a shallow dish and pour the maple syrup mixture over them.
To enhance the flavor of the salmon, cover it and marinate in the refrigerator for at least 30 minutes. For a more intense taste, marinate for 24 hours.
Preheat your oven to 400°F (200°C). Line a baking sheet with foil and lightly grease it.
Place the marinated salmon fillets on the prepared baking sheet, skin side down.
Place the dish in the oven and let it bake for 15 to 20 minutes, or until the salmon is tender enough to be easily separated with a fork.
Garnish with green onions and lemon slices before serving.
