Preheat your oven to 400°F (200°C).
Season the chicken breast evenly on both sides with sea salt and black pepper.
Heat the ghee in a large oven-safe skillet over medium-high heat.
Sear the chicken breast for 3 minutes per side until a golden crust forms, then remove from the pan and set aside.
Add the halved cremini mushrooms to the same skillet and sauté for 5 minutes until they begin to brown and soften.
Add the minced garlic cloves to the skillet and cook for 30 seconds until highly fragrant.
Return the chicken breast to the skillet, nestling it among the mushrooms.
Transfer the skillet to the oven and roast for 10-12 minutes, or until the chicken reaches an internal temperature of 165°F.
Remove from the oven, drizzle with fresh lemon juice, and garnish with chopped parsley before serving.
