Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
In a small shallow bowl, whisk together the almond flour, dried oregano, garlic powder, sea salt, black pepper, and smoked paprika.
Pat the chicken breast dry with a paper towel, then brush it with 0.5 tablespoons of the olive oil.
Firmly press the almond flour herb mixture onto both sides of the chicken until it is evenly and thickly coated.
Place the broccoli florets and sliced carrots on the baking sheet, drizzle with the remaining 0.5 tablespoons of olive oil, and toss to coat.
Nestle the herb-crusted chicken among the vegetables on the sheet pan, ensuring they are in a single layer.
Roast for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are golden and tender.
