Slice the chicken breast into even strips and place them in a bowl with the buttermilk to marinate for 30 minutes.
In a separate shallow dish, whisk together 2 tablespoons of whole wheat flour, almond flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting the excess drip off, and dredge thoroughly in the flour mixture, pressing to ensure a thick coating.
Lightly spray or brush the chicken with avocado oil and place in the air fryer basket at 375°F for 12 to 15 minutes, flipping halfway through until crispy.
While the chicken cooks, melt the ghee in a small saucepan over medium heat, then whisk in the remaining tablespoon of whole wheat flour for one minute.
Slowly pour in the chicken broth while whisking constantly until the gravy thickens into a smooth consistency.
Stir the fresh thyme into the gravy and serve immediately over the hot, crispy chicken strips.
