Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Pat the chicken breast dry with paper towels.
In a shallow bowl, whisk the egg until smooth.
In another bowl, combine almond flour, garlic powder, onion powder, paprika, salt, and black pepper.
Dip each chicken breast first into the egg, ensuring it is fully coated, and then dredge it in the almond flour mixture, pressing lightly to adhere the crust.
Place the crusted chicken on the prepared baking sheet.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the crust is golden and crispy.
Let the chicken rest for a few minutes before serving.
