Preheat your oven to 400°F and place a wire cooling rack over a large baking sheet.
Place the chicken breast in a bowl with the buttermilk and let it marinate for 20 minutes in the refrigerator.
In a shallow dish, whisk together the panko breadcrumbs, garlic powder, onion powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, letting the excess drip off, and dredge it thoroughly in the breadcrumb mixture.
Place the coated chicken onto the wire rack and lightly mist the top with avocado oil spray.
Bake for 18 to 22 minutes, or until the crust is golden brown and the internal temperature reaches 165°F.
While the chicken bakes, prepare the gravy by melting the ghee in a small saucepan over medium heat.
Whisk the whole wheat flour into the ghee and cook for 1 minute to create a light roux.
Slowly pour in the almond milk while whisking constantly until the sauce thickens into a smooth gravy.
Season the gravy with a pinch of salt and pepper, then serve it immediately over the hot, crispy chicken.
