01 - Preheat the oven to 375°F. Allow the salmon to rest at room temperature for 10 to 15 minutes to encourage even cooking.
02 - In a small saucepan over medium heat, combine the soy sauce, brown sugar, minced garlic, lemon juice, butter, salt, and black pepper. Stir constantly and simmer for 2 to 3 minutes until the glaze is smooth and sugar has dissolved. Do not bring the mixture to a boil.
03 - Place the salmon fillet skin-side down in a baking dish. Brush the surface of the salmon with olive oil and season lightly with salt and pepper.
04 - Pour the warm glaze evenly over the salmon fillet. Cover the baking dish tightly with foil to lock in moisture.
05 - Bake for 10 to 25 minutes, depending on the thickness of your salmon (approximately 10 minutes per inch of thickness), until the salmon is cooked through and easily flakes with a fork.
06 - For a caramelized top, remove the foil and broil the salmon for 2 to 3 minutes, watching closely to avoid burning the glaze.
07 - Transfer the salmon to serving plates and garnish with chopped green onion or parsley if desired. Serve immediately with steamed rice, noodles, or roasted vegetables.
