Preheat the oven to 425°F for roasting the asparagus.
Prepare the asparagus by trimming the woody ends, then toss with olive oil, salt, and pepper on a baking sheet.
Roast the asparagus in the preheated oven for about 10-12 minutes until tender and slightly crispy.
Meanwhile, pat the salmon fillet dry with paper towels and season lightly with salt and pepper.
Heat a non-stick skillet over medium-high heat. Once hot, place the salmon skin-side down (if applicable) and sear for about 3-4 minutes until a golden crust forms.
Flip the salmon and reduce the heat to medium, cooking for an additional 3-4 minutes until the fish is just opaque in the center.
In a small bowl, combine the lemon juice and chopped fresh dill.
Plate the salmon alongside the roasted asparagus, and drizzle the lemon-dill mixture over the salmon.
Serve immediately and enjoy your bright, flavorful dinner.
