Remove the salmon from the refrigerator and let it come to room temperature for about 15 to 20 minutes. This ensures even cooking.

In a small bowl, whisk together melted butter, minced garlic, lemon juice, salt, black pepper powder, and dried basil.

Place the salmon fillet skin side down in a glass dish or any ovenproof dish. Pour and spread the prepared marinade evenly over the salmon.

Arrange lemon slices and the whole green chili around the salmon for extra flavor and aroma.

Bake uncovered in a preheated oven at 180°C (356°F) for 20 minutes, or until the salmon flakes easily with a fork.
