Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus and toss them on the baking sheet with half of the olive oil, 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 asparagus roasts, pat the chicken breast dry with a paper towel and season both sides with the remaining salt, pepper, and dried oregano.
Heat the remaining olive oil and ghee in a large stainless steel or cast iron skillet over medium-high heat until shimmering.
Place the chicken in the skillet and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F and the exterior is beautifully golden.
Add the minced garlic to the pan during the last minute of cooking, tilting the pan to baste the chicken with the fragrant infused fat.
Plate the chicken alongside the roasted asparagus and finish with a generous squeeze of fresh lemon juice over everything.
