Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the chicken breast on a cutting board and, if desired, lightly pound it to ensure even thickness for uniform cooking.
In a shallow bowl, whisk the egg until well combined.
In another shallow dish, combine the almond flour, garlic powder, paprika, salt, and black pepper.
Dip the chicken breast into the egg wash, ensuring it is fully coated, then dredge it in the almond flour mixture, pressing lightly so the coating sticks well.
Place the coated chicken breast on the prepared baking sheet. Optionally, lightly spray the top with cooking spray for extra crispiness.
Bake in the preheated oven for 20-25 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the almond crust is golden brown.
Allow the chicken to rest for a few minutes before serving. Enjoy your crispy, almond-crusted chicken!
