Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into half-inch cubes, then toss them on the baking sheet with half the olive oil, sea salt, and smoked paprika.
Roast the sweet potatoes for 20 to 25 minutes, flipping halfway through, until they are tender and slightly caramelized on the edges.
While the potatoes roast, heat the remaining olive oil in a large skillet over medium-high heat.
Add the ground chicken to the skillet, breaking it into small crumbles with a spatula, and season with garlic powder and black pepper.
Cook the chicken undisturbed for 3 to 4 minutes to develop a golden-brown crust, then stir and continue cooking until fully browned.
Add the finely diced red onion to the skillet and sauté for 3 minutes until softened, then stir in the baby spinach until just wilted.
Divide the roasted sweet potatoes and the crispy chicken mixture into bowls and garnish with freshly chopped parsley before serving.
