Slice the chicken breast into even strips or cutlets and place them in a shallow bowl.
Pour the buttermilk over the chicken and let it soak for at least 15 minutes to tenderize.
In a separate shallow dish, whisk together the almond flour, arrowroot powder, garlic powder, onion powder, sea salt, black pepper, and paprika.
Remove each piece of chicken from the buttermilk, letting the excess drip off, then dredge thoroughly in the flour mixture.
Lightly coat the air fryer basket with one teaspoon of avocado oil and arrange the chicken in a single layer.
Air fry at 375°F for 12 to 15 minutes, flipping halfway through and brushing with the remaining oil until the coating is crispy and golden.
While the chicken cooks, pour the chicken bone broth into a small saucepan and simmer over medium-high heat until reduced by half.
Whisk in the heavy cream and a pinch of black pepper, continuing to simmer until the gravy reaches a thick and luscious consistency.
Serve the hot, crispy chicken immediately with the creamy gravy drizzled over the top.
