Slice the chicken breast into even 1-inch thick strips to ensure uniform cooking.
Place the chicken in a shallow bowl and pour the buttermilk over it, ensuring every piece is well-coated.
In a separate wide dish, whisk together the almond flour, arrowroot powder, smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting the excess drip off, then dredge thoroughly in the seasoned flour mixture.
Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Carefully place the chicken in the skillet and cook for 4-5 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
Transfer the chicken to a wire rack for one minute to maintain that signature crispiness before serving.
