Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Slice the fennel bulb into thin wedges or slices and distribute them evenly on the baking sheet. Drizzle with a bit of olive oil and season with salt and pepper.
Peel and grate the fresh ginger, then sprinkle it over the fennel with some citrus zest for an aromatic base.
Rub the salmon fillets with olive oil, then season generously with salt, pepper, and a little citrus juice, coating the top evenly.
Place the seasoned salmon fillets on top of the fennel slices on the baking sheet, spacing them out well.
Transfer the baking sheet to the oven and roast for about 15-20 minutes, until the salmon is flaky and golden at the edges, and the fennel is tender and slightly caramelized.
Remove from the oven and baste the salmon with a splash of citrus juice for extra brightness.
Let the dish rest for a couple of minutes, then serve hot, pairing the tender, caramelized fennel with the crispy, flavorful salmon fillets.
Enjoy this simple yet elegant meal with a side of greens or your favorite grain for a complete dinner.
