In a small bowl, whisk together the maple syrup, soy sauce, Dijon mustard, minced garlic, and grated ginger until well combined.
Place the salmon fillets in a shallow dish or a resealable plastic bag and pour the marinade over them. Make sure each fillet is well coated. Marinate for at least 30 minutes, or up to 2 hours in the refrigerator for enhanced flavor.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and lightly brush it with olive oil to prevent sticking.
Remove the salmon from the marinade, letting any excess drip off, and place the fillets on the prepared baking sheet. Discard the remaining marinade.
Season the salmon fillets with salt and pepper.
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 doneness.
For an extra caramelized finish, turn on the broiler for the last 2-3 minutes of cooking, keeping a close eye to prevent burning.
Remove the salmon from the oven and let it rest for a few minutes.
Garnish with freshly chopped parsley and serve with lemon wedges on the side for added brightness.
Notes
For a gluten-free option, use coconut aminos instead of soy sauce.
