Preheat and prep: Heat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment or foil for easy cleanup.
Pat the salmon dry: Use paper towels to remove excess moisture.
This helps the glaze cling and the fish cook evenly.
Make the glaze: In a small bowl, whisk the Dijon, honey, lemon juice, olive oil, garlic, whole-grain mustard (if using), soy sauce, paprika, salt, pepper, and lemon zest.
Season the fish: Place the salmon skin-side down on the sheet. Sprinkle a light pinch of salt over the top.
Glaze generously: Spoon and spread the honey mustard mixture over the salmon in an even layer, covering all edges.
Bake: Cook for 12–16 minutes, depending on thickness. The salmon should flake easily with a fork and be just opaque in the center.
Aim for an internal temp of 125–130°F for medium.
Optional broil: For a lightly caramelized top, broil for 1–2 minutes at the end. Watch closely to prevent burning.
Rest and garnish: Let the salmon rest 3–5 minutes. Scatter chopped herbs over the top and add pomegranate arils or orange slices if desired.
Serve: Transfer to a platter with lemon wedges.
Pair with roasted Brussels sprouts, green beans, or a citrusy salad.
