Preheat the Oven: Set your oven to 400°F (200°C). Line your baking sheet with foil or parchment for easy cleanup.
Make the Glaze: In a saucepan, combine diced peaches, bourbon, honey, soy sauce, Dijon mustard, garlic, ginger, and lemon juice. Bring to a gentle simmer over medium heat, stirring often, until the mixture thickens slightly (about 8–10 minutes).
Prepare the Salmon: Pat salmon dry with paper towels. Season with salt and pepper, then brush lightly with olive oil.
Add the Glaze: Spoon the peach-bourbon glaze generously over the salmon fillets.
Roast: Bake for 12–15 minutes, depending on thickness, until the salmon flakes easily with a fork.
Finish: Broil for 1–2 minutes to caramelize the glaze, if desired. Serve with a drizzle of extra glaze and fresh herbs.
