In a small bowl, whisk together the maple syrup, soy sauce, Dijon mustard, minced garlic, and grated ginger until well combined. This will be your glaze.
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Place the salmon fillets on the prepared baking sheet, skin-side down. Season them lightly with salt and pepper.
Brush the maple glaze generously over each salmon fillet, reserving some glaze for a final brush later.
Bake the salmon in the preheated oven for 12-15 minutes, or until the salmon flakes easily with a fork and is cooked to your desired level of doneness.
Once done, remove the salmon from the oven and brush with the reserved glaze for added flavor.
Let the salmon rest for a couple of minutes before serving. Garnish with chopped green onions and serve with lemon wedges on the side.
Notes
Serve with steamed asparagus or quinoa for a complete meal.
