Preheat your oven to 425°F and line a baking tray with parchment paper.
In a bowl, pour the buttermilk and season with salt and pepper. Add the chicken breast, ensuring each piece is well-coated, then let it marinate for at least 30 minutes in the refrigerator.
In a separate shallow bowl, mix the almond flour, garlic powder, paprika, a pinch of salt, and pepper.
Remove the chicken from the buttermilk, letting the excess drip off, then dredge each piece in the almond flour mixture ensuring an even, light coating.
Arrange the coated chicken on the prepared baking tray. For extra crispiness, lightly spray or drizzle a minimal amount of olive oil over the top.
Bake in the preheated oven for 20-25 minutes or until the chicken is cooked through and the coating is golden and crispy.
Allow the chicken to rest for a few minutes before serving to retain its juiciness.
