Preheat the oven to 400°F (200°C).

In a bowl, mix together bourbon, soy sauce, honey, and ginger to create the marinade.

Place salmon fillets in a baking dish and pour the marinade over them, ensuring they are well coated.

Slice the peaches and red onion and arrange them around the salmon in the baking dish.

Drizzle olive oil over the peaches and onion, and sprinkle with chopped basil.

Roast the salmon and toppings in the oven until the salmon is cooked through and flakes easily with a fork.
