Preheat your oven to 375°F (190°C). This is the perfect temperature for roasting the salmon while keeping it moist and tender.
Line a baking sheet with parchment paper for easy cleanup. This also helps prevent the salmon from sticking.
Place the lemon slices on the prepared baking sheet. These will serve as a flavorful base for the salmon and help infuse it with citrus goodness.
In a medium bowl, whisk together the melted butter, honey, Dijon mustard, lemon juice, salt, and pepper until well combined. This sweet and tangy glaze will elevate the salmon's flavor.
Lay the skin-on salmon fillet over the lemon slices on the baking sheet. This not only adds flavor but also helps keep the fish from drying out.
Generously brush the honey Dijon glaze over the salmon, ensuring it’s well coated. Reserve a little of the glaze for basting later if desired.
Transfer the baking sheet to the preheated oven and bake for about 15-20 minutes, or until the salmon flakes easily with a fork. If you’re looking for a slightly caramelized top, you can broil it for the last few minutes.
Once done, remove the salmon from the oven and let it rest for a few minutes. Garnish with finely chopped fresh parsley before serving for a pop of color and freshness.
