Slice the chicken breast into even strips.
Place chicken in a bowl with buttermilk and let soak for 10 minutes.
In a separate shallow dish, whisk together almond flour, arrowroot starch, garlic powder, onion powder, sea salt, black pepper, and paprika.
Remove each chicken strip from the buttermilk, allowing excess to drip off, then dredge thoroughly in the flour mixture.
Lightly coat the air fryer basket with avocado oil and arrange chicken in a single layer.
Air fry at 400°F for 12 minutes, flipping halfway through, until the coating is crisp and golden.
While chicken cooks, steam the broccoli florets until vibrant green and tender.
Serve the crispy chicken alongside the steamed broccoli.
