Put 2 layers of aluminum foil on a baking sheet. Put the salmon top.
Combine minced garlic, sesame oil, lemon juice, fish sauce, soy sauce, oyster sauce, and granulated sugar in a bowl. Mix and coat the salmon with the marinade. Let it marinate for 15 minutes.
Preheat the oven to 425 degrees F (218 degrees C).
Drizzle melted butter over the top of the salmon.
Bring together the ends of the first piece of aluminum foil to enclose the salmon. If you have a big piece of salmon, you may need another piece of aluminum foil.
Bake in the oven covered for 15 minutes.
After 15 minutes, uncover the salmon and bring the oven to broil. Broil the salmon for 5-10 minutes until it gets a light golden brown on top. Remove from the oven.
Combine green onions and vegetable oil in a sauce pan. Cook for 10-15 seconds until the green onions are shiny. Drizzle over the salmon.
Lastly, top with peanuts and serve.
