Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
In a small bowl, whisk together olive oil, lemon juice, garlic, mustard, honey, salt, and pepper.
Place the salmon fillets on the prepared tray and brush the sauce mixture over each piece evenly.
Let the salmon rest for 10 minutes to soak up some flavor while the oven finishes heating.
Bake for 12-15 minutes, depending on the thickness of your fillets, until the salmon flakes easily with a fork.
Remove from the oven and let it sit for a couple of minutes before serving. This helps the juices settle inside.
Garnish with fresh herbs and lemon slices before plating.
