Directions
Preheat your oven to 400°F (200°C). Line a sheet pan with parchment paper or lightly grease it.

Dot the leeks with small pieces of butter and roast them in the oven for about 10 to 15 minutes until they begin to soften.
Remove the pan from the oven and place the salmon fillets on top of or beside the leeks. Season the salmon with salt, pepper, and lemon zest.
In a small bowl, mix melted butter with minced garlic and lemon juice. Spoon the mixture over the salmon.
