Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and place them on the prepared baking sheet.
Drizzle the asparagus with 0.5 tablespoon of olive oil and season with a pinch of sea salt and black pepper.
Roast the asparagus for 12-15 minutes until they are tender and slightly charred at the tips.
While the vegetables roast, season the chicken breast on both sides with sea salt, black pepper, and dried oregano.
Heat the remaining 0.5 tablespoon of olive oil in a medium skillet over medium-high heat.
Place the chicken in the skillet and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F.
Add the minced garlic to the skillet during the final minute of cooking, stirring constantly to avoid burning.
Pour the lemon juice into the skillet to deglaze the pan, using a wooden spoon to scrape up any flavorful browned bits.
Remove from heat and garnish the chicken with lemon zest and fresh parsley before serving alongside the roasted asparagus.
