Place the chicken breast in a bowl and cover with buttermilk, marinating for at least 30 minutes in the refrigerator.
In a shallow dish, whisk together the 2 tablespoons of whole wheat flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove the chicken from the buttermilk, letting the excess drip off, and dredge thoroughly in the seasoned flour mixture.
Lightly spray or brush the chicken with avocado oil and place in the air fryer basket.
Air-fry at 375°F for 12-15 minutes, flipping halfway through, until the exterior is golden and the internal temperature reaches 165°F.
While the chicken cooks, melt the ghee in a small saucepan over medium heat.
Whisk in the remaining teaspoon of flour and cook for 1 minute to create a roux.
Slowly pour in the almond milk while whisking constantly, adding the dried thyme, and simmer until the gravy is thick and smooth.
Serve the crispy chicken immediately with the warm gravy drizzled over the top.
