Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking.
In a small bowl, whisk together the maple syrup, soy sauce, Dijon mustard, lemon juice, minced garlic, and grated ginger until well combined.
Place the salmon fillets on the prepared baking sheet, skin-side down. Season the fillets with salt and black pepper.
Brush the maple glaze generously over the salmon fillets, ensuring they are well coated. Reserve some of the glaze for basting later.
Bake the salmon in the preheated oven for 12-15 minutes, or until the fish flakes easily with a fork. After the first 10 minutes, baste the salmon with the reserved glaze for added flavor.
Once cooked, remove the salmon from the oven and let it rest for a couple of minutes.
Garnish the salmon with finely chopped green onions and a sprinkle of sesame seeds before serving.
Notes
For a gluten-free option, use tamari instead of soy sauce.
