Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and place them on the prepared baking sheet.
Drizzle 0.5 tablespoons of olive oil over the asparagus and toss with a pinch of sea salt and black pepper.
Roast the asparagus in the oven for 12 to 15 minutes until tender and slightly charred.
While the asparagus is roasting, season both sides of the chicken breast with sea salt, black pepper, and dried oregano.
Heat the remaining 0.5 tablespoons of olive oil in a large skillet over medium-high heat.
Place the chicken in the skillet and sear for 5 to 7 minutes per side, or until the internal temperature reaches 165°F.
During the last 2 minutes of cooking, add the minced garlic to the skillet and sauté until fragrant, being careful not to burn it.
Remove the skillet from the heat and immediately pour the fresh lemon juice and lemon zest over the chicken.
Plate the lemon herb chicken alongside the roasted asparagus and serve immediately.
