Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus spears and toss them on the baking sheet with the extra virgin olive oil and a pinch of the sea salt and black pepper.
Roast the asparagus in the oven for 12 to 15 minutes until they are tender and slightly charred on the tips.
While the asparagus roasts, season the chicken breast evenly on both sides with the dried oregano and the remaining sea salt and black pepper.
Heat a large skillet over medium-high heat and add the ghee, swirling to coat the bottom of the pan.
Place the chicken breast in the hot skillet and sear for 6 to 7 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
In the final 2 minutes of cooking, add the minced garlic, lemon juice, and lemon zest to the skillet, spooning the bubbling herb ghee over the chicken to baste it.
Serve the chicken alongside the roasted asparagus, drizzling any remaining pan sauce over the plate for extra flavor.
