Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into even, long strips.
In a small shallow bowl, whisk the large egg until well combined.
In a separate shallow bowl, whisk together the almond flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Dip each chicken strip into the egg wash, letting the excess drip off, then dredge thoroughly in the almond flour mixture until fully coated.
Place the coated chicken strips in the air fryer basket in a single layer, ensuring they do not touch.
Air fry for 10 to 12 minutes, flipping halfway through, until the coating is golden brown and the internal temperature reaches 165°F.
While the chicken cooks, steam the broccoli florets for 5 minutes until tender-crisp and bright green.
Serve the crispy chicken tenders immediately alongside the steamed broccoli.
