Preheat your oven to 400°F.
Pat the chicken breast dry and season it with salt, pepper, chopped fresh rosemary, and minced garlic. Set aside.
Wash the sweet potato and cut it into small cubes for a crispier texture.
Place the sweet potato cubes on a baking sheet and drizzle with 1 teaspoon of olive oil, tossing to coat evenly. Season lightly with salt and pepper.
On a separate baking sheet, spread out the broccoli florets. Drizzle with the remaining olive oil and season with salt and pepper.
Place both baking sheets in the oven. Roast the sweet potatoes for about 25-30 minutes until they become crispy on the outside and tender inside, stirring halfway through.
Simultaneously, roast the broccoli for about 20 minutes, until the edges are slightly charred and the florets are tender.
For the chicken, either grill on a preheated grill pan or oven-roast in a separate pan for 20-25 minutes until the internal temperature reaches 165°F.
Once all components are cooked, arrange the chicken on a plate with a serving of crispy sweet potatoes and roasted broccoli.
Serve immediately and enjoy your nutrient-packed, flavor-rich meal.
