Slice the chicken breast into even cutlets and place in a bowl with buttermilk to marinate for 20 minutes.
In a shallow dish, whisk together the 2 tablespoons of flour, arrowroot powder, garlic powder, onion powder, paprika, salt, and pepper.
Remove chicken from buttermilk, letting excess drip off, then dredge thoroughly in the flour mixture.
Heat avocado oil in a large skillet over medium-high heat until shimmering.
Fry the chicken for 4-5 minutes per side until the exterior is deeply golden and the internal temperature reaches 165°F.
Remove chicken to a wire rack and wipe out the skillet while keeping any browned bits.
Melt ghee in the same skillet over medium heat, whisk in the remaining tablespoon of flour, and cook for 1 minute.
Slowly pour in the bone broth while whisking constantly until the gravy thickens into a smooth consistency.
Stir in chopped parsley and pour the warm gravy over the crispy chicken before serving.
