Preheat your oven to 400°F (200°C).
Clean and quarter the cremini mushrooms, mince the garlic cloves, and finely chop the fresh thyme and parsley.
Season the chicken breast evenly on both sides with half of the sea salt and black pepper.
Heat an oven-safe skillet over medium-high heat and add half of the ghee.
Sear the chicken breast for 3 minutes per side until a golden crust forms, then temporarily remove it from the skillet.
Add the remaining ghee and the quartered mushrooms to the same skillet, sautéing for 2-3 minutes until they begin to brown.
Stir in the minced garlic and fresh thyme, then place the chicken breast back into the skillet on top of 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 lemon juice, and garnish with the fresh parsley.
Serve the roasted chicken and garlic mushrooms over the warm cooked quinoa.
