Preheat your oven to 400°F (200°C) and line a 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, 0.5 tablespoons of olive oil, and a pinch of salt and pepper.
Roast the asparagus for 12 to 15 minutes until tender and slightly charred at the tips.
While the vegetables roast, pat the salmon fillet dry with a paper towel and season both sides with turmeric, salt, and pepper.
Heat the remaining 0.5 tablespoons of olive oil in a stainless steel or cast-iron skillet over medium-high heat.
Place the salmon in the pan, flesh-side down, and sear for 4 minutes until a vibrant golden crust forms.
Carefully flip the fillet and cook for another 3 to 4 minutes until the salmon is cooked through and flakes easily with a fork.
Plate the salmon alongside the roasted asparagus and finish with a generous squeeze of fresh lemon juice.
