Preheat your oven to 400°F.
Score the duck skin in a crosshatch pattern using a sharp knife, being careful not to cut into the meat.
Season both sides of the duck breast evenly with sea salt and black pepper.
Place the duck breast skin-side down in a cold oven-safe skillet and turn the heat to medium-low to render the fat for 8-10 minutes.
Increase the heat to medium-high to crisp the skin until golden brown, then flip the breast over.
Transfer the skillet to the oven and roast for 5-7 minutes until the internal temperature reaches 135°F for medium-rare.
While the duck roasts, whisk the orange juice, orange zest, honey, coconut aminos, and grated ginger in a small saucepan over medium heat until the sauce thickens into a glaze.
Toss the asparagus spears with olive oil and a pinch of salt, then roast on a separate baking sheet for 10 minutes until tender-crisp.
Remove the duck from the oven and let it rest for 5 minutes before slicing.
Drizzle the warm orange glaze over the sliced duck and serve alongside the roasted asparagus.
