Preheat your oven to 425°F.
Rinse the salmon fillet and asparagus under cold water. Pat them dry with a paper towel.
Season the salmon fillet generously with a pinch of salt and black pepper on both sides.
In an oven-safe skillet, heat 1/2 tablespoon of olive oil over medium-high heat.
Place the salmon in the skillet, skin-side down if applicable, and sear for about 3 minutes until the exterior becomes crispy.
Carefully flip the salmon and sear the other side for an additional 3 minutes.
While the salmon is searing, line a baking tray with parchment paper, toss the asparagus with a light drizzle of olive oil (if desired) and a pinch of salt and pepper.
Place the asparagus in the preheated oven and roast for around 8-10 minutes until tender-crisp.
After searing, if your skillet is oven-safe, you can transfer the salmon to the oven to finish cooking for an additional 3-4 minutes, or serve immediately with the roasted asparagus.
Plate the salmon alongside the roasted asparagus and enjoy your balanced, flavorful meal.
