Preheat your oven to 400°F (200°C).
In a mixing bowl, whisk together the Dijon mustard, honey, olive oil, lemon juice, garlic powder, salt, and pepper until well combined.
Place the salmon fillets in a baking dish, skin side down.
Brush the Dijon sauce generously over each salmon fillet, making sure to coat them evenly.
Bake the salmon in the preheated oven for 12-15 minutes, or until the salmon flakes easily with a fork and has reached an internal temperature of 145°F (63°C).
Once done, remove the fish from the oven and let it rest for a few minutes.
Garnish with freshly chopped parsley before serving.
For added flavor, consider marinating the salmon in the Dijon sauce for 30 minutes before baking.
