Pat the salmon fillet dry with paper towels and season both sides with sea salt, black pepper, and garlic powder.
In a small bowl, whisk together the Greek yogurt, lemon juice, lemon zest, and chopped fresh dill to create the sauce.
Heat the olive oil in a non-stick skillet over medium-high heat until shimmering.
Place the salmon in the skillet, skin-side down, and sear for 4-5 minutes until the skin is crispy and golden.
Carefully flip the salmon and cook for an additional 2-3 minutes, or until the internal temperature reaches 145 degrees Fahrenheit.
While the salmon cooks, steam the asparagus spears for 3-4 minutes until they are vibrant green and crisp-tender.
Plate the salmon alongside the asparagus and top the fish with a generous dollop of the lemon-dill sauce.
