Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the sweet potato into thin wedges, place them on one side of the baking sheet, and lightly spritz with half of the avocado oil.
Place the chicken breast in a shallow bowl and pour the buttermilk over it, allowing it to soak for at least 10 minutes.
In a separate shallow dish, whisk together the almond flour, arrowroot powder, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove the chicken from the buttermilk, letting any excess drip off, and dredge it thoroughly in the flour mixture, pressing firmly to ensure an even coating.
Place the coated chicken on the other side of the baking sheet and lightly spray the top with the remaining avocado oil to help it crisp up.
Bake for 20 to 25 minutes, flipping the sweet potatoes halfway through, until the chicken reaches an internal temperature of 165°F and the coating is golden brown.
While the chicken finishes, steam the broccoli florets for 5 minutes until tender-bright green.
Serve the crispy chicken alongside the roasted sweet potato wedges and steamed broccoli for a balanced, clean-eating meal.
