Preheat your oven to 400°F.
Cube the sweet potato into bite-sized pieces and toss with half a teaspoon of olive oil, salt, and black pepper. Spread evenly on a baking sheet.
Roast the sweet potato in the preheated oven for 20-25 minutes until tender and slightly caramelized.
While the sweet potato roasts, chop the broccoli into florets, drizzle with a tiny bit of olive oil, and season lightly with salt and pepper.
Spread the broccoli on another baking sheet and roast in the oven for about 15 minutes until tender but still crisp.
Season the chicken breast on both sides with salt, black pepper, and garlic powder.
Heat a non-stick skillet over medium-high heat with the remaining olive oil. Once shimmering, add the chicken breast.
Sear the chicken breast for about 4-5 minutes on each side until a crispy, golden crust forms and the internal temperature reaches 165°F.
Rest the chicken for a few minutes before slicing. Serve with the roasted broccoli and sweet potato on the side.
