Slice the chicken breast into even strips or medallions to ensure even cooking.
Place the chicken in a small bowl and pour the buttermilk over it, stirring to coat every piece.
Let the chicken marinate for at least 10 minutes to tenderize the meat.
In a separate shallow dish, whisk together the almond flour, arrowroot starch, sea salt, black pepper, garlic powder, and smoked paprika.
Lift each piece of chicken from the buttermilk, letting the excess liquid drip off, and dredge it thoroughly in the seasoned flour mixture.
Heat the avocado oil in a large non-stick skillet over medium heat until shimmering.
Carefully place the breaded chicken in the skillet and cook for 4 to 5 minutes per side until the crust is golden brown and the internal temperature reaches 165 degrees Fahrenheit.
While the chicken finishes, lightly warm the whole-wheat biscuit in a toaster oven until the edges are slightly crisp.
Transfer the crispy chicken to a plate lined with a paper towel for a moment to drain any excess oil.
Serve the hot fried chicken immediately with the warm biscuit on the side.
