Slice the chicken breast into even strips or a thin cutlet to ensure quick and even cooking.
Place the chicken in a shallow bowl and cover with buttermilk, letting it soak for 15 minutes to tenderize.
In a separate bowl, whisk together the 2 tablespoons of arrowroot powder, sea salt, black pepper, garlic powder, onion powder, and smoked paprika.
Remove the chicken from the buttermilk and dredge it through the arrowroot mixture until it is thoroughly and evenly coated.
Heat the avocado oil in a cast-iron skillet over medium-high heat until shimmering.
Carefully place the chicken in the skillet and fry for 4 to 5 minutes per side until the coating is golden and crispy.
Transfer the chicken to a plate and wipe the skillet clean; melt the ghee over medium heat.
Whisk the remaining teaspoon of arrowroot powder into the ghee for 1 minute, then slowly pour in the almond milk while whisking constantly.
Simmer the gravy for 2 minutes until thickened, season with the remaining salt and pepper, and pour over the hot chicken.
