Slice the chicken breast into even strips or pound into a thin cutlet for uniform cooking.
Place the chicken in a shallow bowl and pour the buttermilk over it, letting it soak for at least 15 minutes.
In a separate shallow dish, whisk together the 2 tablespoons of flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove each chicken piece from the buttermilk, letting the excess drip off, and dredge thoroughly in the seasoned flour mixture.
Heat avocado oil in a large skillet over medium-high heat until shimmering.
Carefully place the chicken in the skillet and fry for 4-5 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
Transfer the cooked chicken to a plate and set aside, leaving the remaining oil and browned bits in the skillet.
Lower the heat to medium and whisk the remaining teaspoon of flour into the pan drippings for 1 minute.
Slowly whisk in the almond milk, scraping the bottom of the pan, and simmer until the gravy has thickened into a smooth sauce.
Plate the chicken, ladle the warm gravy over the top, and garnish with fresh chopped parsley.
