In a medium glass bowl, prepare marinade by mixing garlic, olive oil, basil, salt, pepper, lemon juice and parsley. Place salmon fillets in a medium glass baking dish, and cover with the marinade. Marinate in the refrigerator about 1 hour, turning occasionally.
Preheat oven to 190 C / Gas 5.
Place fillets in aluminium foil, cover with marinade, and seal. Place sealed salmon in the glass dish, and bake 35 to 45 minutes, until easily flaked with a fork.
