Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
In a shallow bowl, whisk the egg until smooth. In a separate shallow bowl, combine the almond flour, garlic powder, onion powder, dried parsley, sea salt, and black pepper.
Dip each chicken tenderloin first into the egg wash, then dredge it through the almond flour mixture, pressing gently to ensure an even coating on all sides.
Arrange the coated chicken on the prepared baking sheet and lightly drizzle or mist with the extra virgin olive oil to help achieve a golden crisp.
Bake for 15 to 18 minutes, flipping the tenderloins halfway through, until the internal temperature reaches 165°F and the crust is beautifully toasted.
While the chicken is baking, steam the broccoli florets for 5 to 6 minutes until they are tender-crisp and bright green.
Plate the crispy chicken alongside the steamed broccoli and serve immediately.
