Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and place the spears on the baking sheet.
Mince the garlic and toss it with the asparagus, 1 teaspoon of olive oil, and a pinch of salt and pepper.
Roast the asparagus for 10-12 minutes until tender but still vibrant green.
While the vegetables roast, pat the salmon fillet completely dry with a paper towel and season both sides with the remaining salt, pepper, and dried dill.
Heat the remaining 1 teaspoon of olive oil in a stainless steel or cast iron skillet over medium-high heat until shimmering.
Place the salmon in the pan skin-side down and press lightly with a spatula for 10 seconds to ensure even contact; sear for 4-5 minutes until the skin is crispy.
Carefully flip the fillet and cook for another 2-3 minutes until the salmon is just opaque in the center.
Plate the salmon alongside the roasted asparagus and finish with a fresh squeeze of lemon juice over everything.
