Preheat your oven to 425°F (220°C).
Peel and dice the sweet potato into medium cubes. Toss with half the olive oil, salt, and pepper, then spread evenly on a baking sheet.
Roast the sweet potato in the oven for about 20-25 minutes until tender and slightly caramelized.
While the sweet potatoes roast, prepare the chicken: Season the chicken breast with salt and pepper.
In a small bowl, mix the maple syrup, minced garlic, and the remaining olive oil to create the glaze.
Heat a non-stick skillet over medium-high heat. Sear the chicken breast on each side for 2-3 minutes until golden.
Pour the glaze over the chicken, reduce the heat to medium, and cook for an additional 6-8 minutes until the chicken is cooked through and the glaze is sticky and reduced.
Steam or microwave the broccoli until just tender, then season lightly with salt and pepper. To achieve extra crispiness, you can quickly sauté it in a dry pan on high heat for 1-2 minutes.
Plate the glazed chicken breast along with portions of roasted sweet potatoes and crispy broccoli. Drizzle any remaining glaze over the top and serve immediately.
