Slice the chicken breast into even strips and place them in a bowl with buttermilk to marinate for at least 15 minutes.
In a shallow dish, whisk together the arrowroot powder, sea salt, black pepper, garlic powder, and smoked paprika.
Remove chicken from buttermilk, letting excess drip off, then dredge each piece in the arrowroot mixture until fully coated.
Heat avocado oil in a large skillet over medium-high heat until shimmering.
Carefully place chicken in the skillet and cook for 4-5 minutes per side until the coating is golden brown and the internal temperature reaches 165°F.
While chicken cooks, steam the broccoli florets in a small pot with a splash of water until tender-crisp.
Remove chicken from the pan and immediately drizzle with honey while still hot.
Serve the crispy chicken alongside the steamed broccoli.
