Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness to ensure even cooking.
In a shallow bowl, whisk together 2 tablespoons of flour, garlic powder, onion powder, sea salt, and black pepper.
Dip the chicken breast into the buttermilk, allowing any excess to drip off, then dredge in the seasoned flour mixture until fully coated.
Heat the avocado oil in a skillet over medium-high heat until it begins to shimmer.
Carefully place the chicken in the skillet and fry for 4 to 5 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and set it aside on a plate to rest.
Reduce the heat to medium and whisk the remaining 1 teaspoon of flour into the pan drippings for 1 minute.
Slowly pour in the chicken broth and almond milk, whisking constantly until the gravy thickens into a velvety consistency.
Pour the warm gravy over the chicken and garnish with chopped fresh parsley before serving.
