Slice the chicken breast into even cutlets and place them in a bowl with the buttermilk to soak for at least 15 minutes.
In a separate shallow dish, whisk together the almond flour, arrowroot powder, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove each chicken cutlet from the buttermilk, letting the excess drip off, and dredge thoroughly in the seasoned flour mixture until well-coated.
Heat the avocado oil in a large skillet over medium heat and once hot, add the chicken.
Cook the chicken for 4-5 minutes per side until the exterior is golden brown and the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the skillet and set aside on a plate.
To the same skillet, pour in the chicken broth and almond milk, using a whisk to scrape up any flavorful browned bits from the bottom.
Simmer the liquid for 2-3 minutes until it reduces and thickens into a smooth gravy, then pour it over the crispy chicken to serve.
