01 - Preheat your oven to 400°F. Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
02 - In a small saucepan, combine the fresh orange juice, honey, soy sauce, Dijon mustard, orange zest, minced garlic, black pepper, and salt. Bring the mixture to a simmer over medium heat, stirring occasionally. Allow it to cook for 6–8 minutes, or until the glaze slightly thickens. Remove the saucepan from the heat.
03 - Gently pat the salmon fillets dry with paper towels. Arrange them on the prepared baking sheet, ensuring the skin side is down if applicable.
04 - Generously brush each salmon fillet with the prepared orange glaze. Reserve approximately one-third of the glaze for later use.
05 - Transfer the baking sheet to the preheated oven and bake the salmon for 12–15 minutes. The salmon is cooked when the flesh becomes opaque and flakes easily with a fork.
06 - Remove the salmon from the oven. Brush the fillets with the reserved glaze. Garnish with chopped fresh parsley and orange slices, if desired. Serve immediately while warm.
